Introduction Control Dialogs Auto Mixer Combiner Note: The Auto Mixer Combiner replaces the Mix Minus Combiner in the software and incorporates all of its functionality, plus some additional features. Files created in previous versions of Nexia that contain a Mix Minus Combiner will still function normally and the Mix Minus Combiner will still appear in the layout, even though the block will no longer appear in the Object Toolbar or Processing Library.
Nexia Manual LTR When the user first places a Source Selection block into an Nexia layout, this prompts an initialization window. Source Channel Count specifies the number of input channels (2 to 16) and generally corresponds to the number of sources from which the user can choose. If the Source Channel Count is set to Custom, the Chan Count parameter is used to specify the exact number of channels desired. If selected, Enable Logic provides a logic input and output connection point for each channel.
Introduction Balanced Inputs Unbalanced Inputs Unbalanced Stereo to two balanced inputs Outputs Balanced Output Unbalanced Output 3
Nexia Manual LTR Level Mute turns on/off the channel. Channel level may be entered numerically, or may be adjusted by dragging the fader. Maximum and Minimum can be used to restrict the range of level adjustment provided by the fader. Level ID provides a custom label, when the dialog box is minimized (see below). Right-clicking over certain settings will provide a menu of additional options.
Introduction Level Inc/Dec Level Inc/Dec blocks are identical to Level blocks, except they also provide control input nodes for making incremental level changes. Inc/Dec Step determines the amount of level change to occur each time the associated control node is triggered. Control input nodes along the top of the block are labeled as positive (+) and negative (-).
Nexia Manual LTR Mute Button Mute turns on/off the channel. Identifier provides a custom label, when the dialog box is minimized (see below). Right-clicking over certain settings will provide a menu of additional options. Control Dialog Boxes for Mute Button components can be minimized to create user control surfaces (see Customizing Component Objects). When placed from the Object Toolbar, multiple Mute Buttons may be 'ganged' together onto a single button.
Introduction Most Logic Gates have no Control Dialog Boxes. They are used only to customize behavior of other control functions in the system. Logic Gates are connected between the output and input control nodes of other components in the layout. These components can represent internal or external control functions. Examples Internal: Auto Mixer output nodes; Ducker input/output nodes; Remote Preset Button input nodes.
Nexia Manual LTR NOTES: NOT and Flip Flop gates have only a single input per output, whereas most other gates have multiple inputs, up to 8. Flip Flop gates provide a control dialog box, for establishing their initial output state. Also, unlike most other blocks, multiple control output nodes may be connected to a single control input node on a Flip Flop gate. Control Dialog boxes for Logic State gates can be minimized to create user control surfaces (see Customizing Component Objects).
Introduction Command String Command String blocks allow RS-232 control of external devices via NEXIA's Serial port. Control input nodes along the top of the block produce corresponding serial commands, when triggered by control output nodes on other components within the design. Commands can also be initiated using the command button which appears within the control dialog box. Command ID allows the command/button to be named. Command String allows the appropriate character string to be entered.
Nexia Manual LTR Volume 8 The Volume 8 is an external control device, which allows adjustment of eight selectable NEXIA volumes. Volumes can be individual or grouped levels within NEXIA. This includes Level Control blocks, as well as level adjustments found in the Control Dialog boxes of other component blocks. Volume 8 is represented in the layout as a block with no audio or control connections. All functions are assigned using the control dialog box.
Introduction Select 8 The Select 8 is an external control device, which allows initiation of eight selectable NEXIA actions. Actions can be individual or grouped functions within NEXIA. This includes recalling presets, ducking, combining, etc. Select 8 components have no Control Dialog Boxes. They are represented in the layout as a block with eight control output nodes. These control output nodes are connected to control input nodes on the other component blocks to be controlled.
Nexia Manual LTR Volume/Select 8 The Volume 8 is an external control device, which combines the functions of both Volume 8 and Select 8 controls. Therefore, the Volume/Select 8 is represented with a control dialog box (for volume functions), as well as a component block with control output nodes (for select functions). Control Dialog Boxes for Volume/Select 8 components can be minimized to create user control surfaces (see Customizing Component Objects).
Introduction and associated with their corresponding component blocks within the layout (see Equipment Table). RED-1 Remote Ethernet Device 1 (RED-1) is an external remote control panel that integrates with Nexia systems via Ethernet, using a single CAT5 cable for control and Power-over-Ethernet (PoE). RED-1 allows for the selection of up to 32 control items. A control item can be the initiation of a logic event (such as a preset recall or a source selection), selection of a volume assignment, or both.
Nexia Manual LTR A list displays all defined control items, each with a Channel Number and customizable Control Label. The New button creates a control item in the list, and the user is prompted to either accept the default label or enter a new one. Rename allows the user to change the Control Label of the selected control item. Delete removes the selected control item from the list.
Introduction Voltage Control Box The Voltage Control Box (VCB) is an external control device, which provides four analog potentiometer inputs and four logic inputs/outputs. When a VCB is placed, an Initialization Properties dialog box appears for assigning the quantities of logic inputs/outputs (4 total). Although the quantity of logic connections on a Voltage Control Box (4) is different from those on a Logic Box (20), their operation and behavior are identical.
Nexia Manual LTR VCB Calibration Once a VCB (Voltage Control Box) block has been assigned in a Nexia configuration, and the VCB device (with potentiometers attached) is connected to the Nexia Remote Control Bus, the potentiometers can be calibrated for accurate tracking of levels (see Device Maintenance). The first screen encountered in this process allows for the selection of the potentiometer Channel to be calibrated. Channel numbers correspond to the Analog potentiometer connections on the VCB itself.
Introduction When maximum and minimum potentiometer settings have both been recorded, this screen will indicate the voltage measurements and prompt the user to either accept these values or recalibrate. "Finish" will return to the Channel selection screen. NOTE: The entire range of level adjustment assigned to a potentiometer will be controlled by the voltage range measured during calibration.
Nexia Manual LTR Logic Box behavior can be altered using Logic Gates. Please refer to the 'Installation Guide' (included with controls), or see Remote Control Bus for more information. External controls must be identified (see Device Maintenance) and associated with their corresponding component blocks within the layout (see Equipment Table). Up to 20 logic inputs are availble on the Logic Box.
Introduction Control Labels The Volume 8, Select 8, and Volume/Select 8 controls all come with a sheet of clear, adhesive-backed labels, for custom printing on a laser printer. A Word document is available on the NEXIA software CD and on the Biamp web site (www.biamp.com), as a label printing template. These labels are meant to be printed using desk-top laser printers only. It is recommended that the printer be set for 'label' printing, and the label sheet should be 'shortedge' feed from the 'bypass' tray.
Nexia Manual LTR In the Word document, select Show Gridlines from the Table menu. Each large cell represents a label. The first four columns are 'left-justified' to create labels for Volume 8 and Select 8 panels, as well as for the 'Volume' (left) section of Volume/Select 8 panels. The last column is 'right-justified' to create labels for the 'Select' (right) section of Volume/Select 8 panels. Leftclick inside any large cell, and begin typing.

ERLE (Echo Return Loss Enhancement) indicates the amount of processing being applied on that channel. TER (Total Echo Reduction) shows the combined echo reduction achieved by acoustic damping (ERL) and signal processing (ERLE).
Nexia Manual LTR blocks should typically receive 'far-end' (Codec In) and ‘program’ signals only (not microphones), and be connected as close as possible to the output, so as to reflect any level adjustments and signal processing applied for local sound reinforcement of those same signals. This approach provides the most accurate reference. AEC Ref blocks should never be connected to paths containing signal from corresponding AEC Inputs.

Input Level provides muting and level adjustment for the normal audio input, which appears as the upper input on the left side of the Ducker. Sense Level provides muting and level adjustment for the signal trigger input, which appears as the lower input on the left side of the Ducker. Threshold determines what sense input signal level will trigger ducking.
Component Objects Ambient Noise Compensator Ambient Noise Compensators automatically adjust program volume in response to changes in background noise levels, as monitored by external ambient sensing microphone(s). Program Mute turns the program input signal on/off. Program Level adjusts the relative program input volume. Program Label provides a custom label, when the dialog box is minimized (see below). Prog Meter displays the current program input level.
Nexia Manual LTR Feed the "ambient" signal into the Ambient Input (bottom left, marked with an "A") of the ANC block. This signal should be derived from either a single dedicated sensing microphone, or from a dedicated array of sensing microphones feeding a common Mixer block. Setup of the ANC block is best done when the ambient noise in the room(s) is minimal, but the Ambient Meter should read at least -60dBu. Connect the output of the ANC block to its destination.
Component Objects Press the "Set Threshold" button, ensuring that the Program Input level is a good approximation of the highest program signal level you expect will be fed to the ANC. This process records the levels of both the Ambient and Program inputs. The Ambient Threshold is set to 10dBu higher than the recorded Ambient level. This process takes up to 5 seconds.

System Design Placing Component Objects System design begins with the placement of Component Objects into the Layout. This can be done in two ways. The simplest way is to select a component category from the Processing Library, and then drag & drop a pre-defined component into the Layout. Processing Library component categories can also be selected from the Processing Library Menu (at the top of the screen), which indicates keyboard short-cuts as well.
Nexia Manual LTR To make a connection, click on a Node, move the mouse to a corresponding Node, and click again to place a Line Object (wire). Multiple Nodes on one or more objects can be selected as a group (click & drag to select). Then, by clicking on the top selected Node, these multiple Nodes may be connected to a matching set of multiple Nodes on one or more other objects, in the same manner as described previously for a single connection.
System Design Customizing Component Objects Component Objects can be customized in several ways. First, when using the Object Toolbar to place components into the Layout, certain components will present the user with a pop-up ‘Initialization Properties’ window of configuration options. Several pre-defined configuration (input/output) options may be available for the component, as well as a 'custom' selection that allows the user to more specifically configure the component.
Nexia Manual LTR Object and Layout Text The size and appearance of both text and objects can be customized. Special Text Objects can be placed into the Layout using the Text cursor on the Object Toolbar. When selected, Component & Text Objects display handles which can be dragged for re-sizing. Right-clicking over an object provides a pop-up menu which includes the Edit Text option. Edit Text can also be accessed for a selected object by simply pressing the Enter key.
System Design see a list of possible Compile Error Messages Compile Error Messages Validation of the Topology Map Message: The Automatic Mixer (object code '__') at [__,__] has no active audio output. Explanation: An Auto Mixer Main Output is connected to a Mix-Minus Combiner input, but appropriate audio output connections have not been made. Mix-Minus Combiners allow Auto Mixers to share control data only, and do not support audio input or output. Message: Unintended use of Combiner block detected.
Nexia Manual LTR Explanation: The main output of an Auto Mixer can be connected to only a single Combiner input (Mix-Minus or Room). Otherwise, Auto Mixer control data might be shared with multiple groups of combined mixers, causing convoluted behavior. Message: Empty layout ! Explanation: No objects have been placed in the layout. Messages: There are no audio sources or destinations. There are no audio sources. There are no audio destinations.

Explanation: Although quite large, there is a limit to the quantity of control connections within a single unit.
Nexia Manual LTR The PC computer, running NEXIA software under Windows® XP Professiona/Vista, must have a 10/100 BaseT network card (NIC) installed. When connecting directly to the Ethernet port on a single NEXIA unit, a 'cross-over' CAT5 cable is used. When connecting to a network (or system) of multiple NEXIA units, a 'straight-through' CAT5 cable is used (via an Ethernet switch).
System Design System Connect Considerations The System Connect screen provides a System List (configured devices only) and a Device List (all configured and non-configured devices). When a selection is made in the System List, Connect To System will establish communication with, and retrieve the configuration from, the device(s) in that system. Send System Config will attempt to send an open file of a properly compiled system configuration to the device(s) specified in the Equipment Table.
Nexia Manual LTR Send Configuration and specific Device Maintenance functions (Reset/Initialize, Set IP Address, and Update Firmware) are not allowed during a multi-client session. All other system users must disconnect before these functions can be performed. Send Configuration often affects multiple devices, which will be unavailable to other users during this process. Device Maintenance functions affect individual devices, which will be unavailable to other users during this process.
System Design 159
Nexia Manual LTR Proper Gain Structure Proper gain structure is important because it affects signal-to-noise performance and available headroom within a sound system. Every sound system has some inherent noise, whether it be self-generated by the internal electronics or induced into the signal path by external sources. Therefore, unnecessarily low gain settings can result in signal levels which are significantly closer to the noise floor, potentially causing a sound system to appear noisy.
System Design To establish proper gain structure, the primary element is input gain. Each system input provides adjustable Gain In (trim), with an associated Peak indicator. For best performance, increase gain on a given input until the Peak indicator just begins to flash on normal signal content. The Peak indicator first comes on with 6dB of headroom remaining (before clipping occurs).
System Control Software User Interface Once a system design is compiled and downloaded into NEXIA devices, the system can be controlled in real-time the via the NEXIA software. The extent of control can be limited with different password levels. In addition, Control Dialog Boxes for certain Combiners, Dynamics, Controls, & Meters components can be minimized to create customized control surfaces (room combiners, meters, level controls, mute buttons, & preset buttons).
System Control Cabling and power for an RCB network can be calculated using a program (NexiaRCBCabling.hta) found under Program Files/Nexia/Ultilities. Controls are wired in parallel (pin-for-pin), using 5-conductor data grade cable (95~120 ohms nominal impedance; 16 pF/ft. max. capacitance; 65% min. velocity of prop.). Recommended cable: Gepco 18/22AXL, Liberty AXLINK, Liberty CRESNET, or equivalent (use data pair for Hi & Lo; use power pair for + & -).
Nexia Manual LTR Remote Control Bus Hub 164
System Control The Remote Control Bus Hub provides eight parallel ports for the connection of remote control devices to an Nexia® system. Each port can accept multiple remote controls connected in a 5wire daisy-chain. A single Hub, connected to a single Nexia unit, allows multiple branches to be added to the remote control network. Also, maximum cable length is calculated only across the two longest network branches, thereby effectively extending the network range.
Nexia Manual LTR NTP strings require a space between each parameter; the last character in the string needs to be a line feed . A space is not required before a line feed, but is acceptable and is used in examples shown in this manual (for legibility only). A space normally proceeds the carriage return/line feed in a response to a GET command (see Command and Responses).
System Control RS-232 Control The RS-232 port on the back of an Nexia unit is set to a default baud rate of 38400, 8 data bits, no parity, 1 stop bit, and no flow control. (38400:8:None:1). If multiple Nexias are connected together in a system then only one RS-232 port needs to be connected to a third-party control system; communication data is shared via Ethernet through a switch.

To turn echo back ON during a session: Send byte sequence 0xFF 0xFD 0x01. Receive 3 byte response from server (0xFF 0xFB 0x01 = echo ON). Send desired commands.
System Control Example: With a returned GETL response of 405, divide by 10 (405 / 10 = 40.5), and then subtract 100 (40.5 – 100 = -59.5dB) For your reference, the SETL/GETL Table on the following page shows .5dB increments converted into the SETL/GETL format. Some Attributes do not support all commands. The Attribute section defines which commands support SET/SETL, GET/GETL, INC, or DEC functions. RECALL is only used on preset commands. DIAL is only used on telephone dialing commands.
Nexia Manual LTR Device Number A Nexia Device Number represents the physical Nexia box’s defined address. The Nexia software automatically sets this number when a system is Compiled and loaded.
System Control The Device number that a DSP block has been assigned to can be determined in 3 ways: First Way: 1. Right click on the DSP block and select ‘Properties’. 2. Click on DSP 1 attributes tab and scroll down. The device that the block is assigned to will be displayed in the ‘Allocated To Unit’ field. Second Way: 1. In the Display tab of the Options screen select "Display Device Assignment in DSP Block info field".
Nexia Manual LTR Attribute The Attribute defines the portion of the DSP block to be controlled (fader level, crosspoint mute etc). The following tables show whether each NTP Attribute supports SET/SETL, GET/GETL, INC, and DEC Commands, as well as the Value range that the Attribute will accept. Index1/Index2 determines whether Index1, Index2 or BOTH are needed for a NTP String to be complete.
System Control Invert Polarity INPINVRT SET, GET 1 0 =normal 1 = inverted * Can contain a decimal number. Note: Nexia SP Line Inputs only support input gain values of 0, 6, 12, & 18 (dB). Example: Set Device 1 Input Level at Instance ID 6, Input 3 to –10dB.
Nexia Manual LTR The following table of Attributes is valid only for Nexia PM Stereo Line Inputs.
System Control Phantom Power AECPHPWR SET, GET 1 0 = off 1 = on Input Mute AECINPMUTE SET, GET 1 0 = unmuted 1 = muted Invert Polarity AECINPINVRT SET, GET 1 0 =normal 1 = inverted Enable AEC AECENABLE SET, GET 1 0 = off 1 = on NLP Strength AECNLP SET, GET 1 0 = off 1 = soft 2 = medium 3 = aggressive Noise Reduction AECNR SET, SETL, GET, GETL 1 0, and 6 ~ 15 * Can contain a decimal number. Example: Set Device 1 AEC NLP Strength at Instance ID 24, Input 3 to aggressive.
Nexia Manual LTR Last Number TILASTNUM GET None None TISPEEDDIAL DIAL None 1 ~ 16 TIPHONENUM DIAL None enter the phone Dialed Speed Dial Entry to Dial Phone Number to Dial number Redial TILASTDIALED DIAL None none Note: The TC can insert delay while dialing a phone number by inserting commas where desired (each comma provides 1 second of delay). Most PBX systems require delay after acquiring an outside line.
System Control Note: GET 1 TICIDUSER 23 will return: "" "" "" if there is no caller ID information available. The first set of quotes contains the date and time in the format MMDDHHmm. The second set of quotes represents the incoming phone number in the format 5036417287. The third set of quotes contains the name of the caller. If there are quotes contained within the name, there will be a backslash preceding the quotes within the name, i.e. "David \"Dawg\" Grisman".
Nexia Manual LTR Rings Before 1, 2, 3, 4, or 5 Auto-Answer Line Echo TIRXLEC SET, GET None Cancellation 0 = off 1 = on Noise TIRXNS SET, GET None Suppresion 0 = off 1 = on * Can contain a decimal number. TC Transmit Attribute Commands Index Value Range Transmit Level TITXLVL SET, SETL, GET, GETL, INC, DEC None -100 ~ 0 * Transmit Mute TITXMUTE SET, GET None 0 = unmuted 1 = muted * Can contain a decimal number.
System Control 1 = muted Crosspoint Mute AMMUTEXP SET, GET 1 1 =unmuted 0 = muted Logic Output AMLOGOUT GET 2 0 = off 1 = on * Can contain a decimal number. Note: Typically, Index1 represents the input/row, and Index2 represents the output/column. However, Automixers have only a single output and, therefore, Index2 is not used to specify an output/column. Example: Set Device 1 Automixer Crosspoint Mute at Instance 3 Crosspoint 1 to muted.
Nexia Manual LTR Standard Mixer Attribute Commands Index Value Range Input Level SMLVLIN SET, SETL, GET, GETL, INC, DEC 1 -100 ~ 12 * Output Level SMLVLOUT SET, SETL, GET, GETL, INC, DEC 2 -100 ~ 12 * Input Mute SMMUTEIN SET, GET 1 0 = unmuted 1 = muted Output Mute SMOUTMUTE SET, GET 2 0 = unmuted 1 = muted Crosspoint Mute SMMUTEXP SET, GET 1 & 2 1 = unmuted 0 = muted * Can contain a decimal number.
System Control Example: Set Device 1 Room Combiner Wall State at Instance 4 Wall 2 to up (close/separate). Command Dev # Attribute Inst ID Index 1 Index 2 Value Line Feed SET 1 RMCMBWALL 4 2 None 1 Result: SET 1 RMCMBWALL 4 2 1 Mix-Minus Combiner Attribute Commands Group State MCMBGROUP SET, GET Index 1 Value Range 0 ~ 32 Note: Index1 is the input being addressed.
Nexia Manual LTR * Can contain a decimal number. Note: Index1 represents the filter to be controlled. Parametric EQ filters are initially numbered from left to right, and the selected band is displayed in the upper left hand corner of the Parametric EQ dialog screen in Nexia software. Use this number as Index1 for Parametric EQ strings. Example: Increment Device 1 Parametric EQ Band Level at Instance 11 Band 2 by 2dB.
System Control * Can contain a decimal number. * Can contain a decimal number. * Can contain a decimal number. Example: Set Device 1 High Shelf Filter Gain at Instance 100 to -10dB. Result: SET 1 HSFLTGAIN 100 –10 * Can contain a decimal number.
Nexia Manual LTR Note: Index1 represents the filter band to be controlled. All-Pass Filter bands are initially numbered from left to right, and the selected band is displayed in the upper left hand corner of the All-Pass Filter dialog screen in Nexia software. Use this number as Index1 for All-Pass Filter strings. Crossover Blocks * Can contain a decimal number. * Can contain a decimal number. * Can contain a decimal number.
System Control 4-way crossover: Index1 = 1 is the low-pass filter cut-off frequency Index1 = 2 is the lower slope of the low-mid filter cut-off frequency Index1 = 3 is the higher slope of the low-mid filter cut-off frequency Index1 = 4 is the lower slope of the mid-high filter cut-off frequency Index1 = 5 is the higher slope of the mid-high filter cut-off frequency Index1 = 6 is the high-pass filter cut-off frequency Example: Get Device 2 Crossover 3-Way Cut-Off Frequency at Instance 40 Low-Pass filter.
Nexia Manual LTR * Can contain a decimal number. Example: Set Device 3 Noise Gate Bypass at Instance 55 to active. Result: SET 3 NGBYP 55 0 Router Blocks Router Attribute Commands Index Crosspoint RTRMUTEXP SET, GET, SETD, GETD Value Range 1 & 2 1 = unmuted 0 = muted Note: For attributes with 2 Index fields, Index1 is the input/row, and Index2 is the output/column. Example: Set Device 1 Router Crosspoint at Instance 98 Row 4 Column 5 to muted.
System Control SET 1 RTRMUTEXP 98 4 5 0 Result: SET 1 RTRMUTEXP 98 4 5 0 Source Selection Attribute Commands Index Source SRCSELSRC SET, GET, SETD, GETD 1 Value Range 0 = No Source/muted 1 = Source 1 2 = Source 2 3 = Source 3 Level SRCSELLVL SET, GET, SETL, GETL, SETD, GETD 1 -100 ~ 12 Example: Set Device 1 Source Selection Source at Instance 99 Source 2 selected.
Nexia Manual LTR * Can contain a decimal number. Note: Value Range is from 0 to the maximum value for the specific delay block. For example, a 50mSec delay has a maximum setting of 1717 centimeters, 17 meters, 676 inches, or 56 feet. Example: Set Device 1 Delay In Centimeters at Instance 24 to 40 centimeters. Result: SET 1 DLYCM 24 40 Control Blocks * Can contain a decimal number.
System Control Note: Instead of SET, SETL, GET, GETL, INC, or DEC; the Preset attribute uses RECALL as the command. Preset numbers begin at 1001. Regardless of preset name, the first preset defined is 1001, the second is 1002, and so forth. However, the numbers of any deleted Presets will not be available. Since Presets apply to entire systems, the Device Number will always be 0 for Preset strings. Example: Recall Device 0 Preset number 1001.
Nexia Manual LTR Nexia uses an Instance ID number to specify the exact DSP block to be controlled. Custom names (Instance ID Tags) may be assigned to DSP blocks, and used in lieu of Instance ID numbers within NTP command strings. Instance ID Tags may be up to 32 characters, but may not start with a number. If the Instance ID Tag includes spaces, it must be double-quote delimited ("Instance ID Tag") when used in a command string.
System Control Example: DEC 2 AMLVLOUT 6 1 2 In an Auto Mixer on Device 2 we are decreasing the level of output 1 on instance ID 6 by 2dB. Index2 is used to represent the output number. Example: SET 1 MMLXP 5 1 2 –5 In a Matrix Mixer on Device 1 we are setting crosspoint 1:2 (Input/Row 1, Output/Column 2) level to –5dB on instance ID 5. Note: For commands with 2 Index fields, Index1 is the Input/Row, and Index2 is the Output/Column.
Nexia Manual LTR Value determines what a DSP block is being set to, incremented by, or decremented by. The Attribute section will define which type of value the string will need in order to execute the NTP string. Example: INC 1 AMLVLIN 4 1 1 In an Automatic mixer input level string, the Value equal to 1 states that the fader is to be incremented by 1 dB. Example: SET 2 MMLVLIN 5 2 –100 In a matrix mixer input level string, the value is set to –100dB.
System Control GET 2 AMLVLIN 4 2 would result in the response: 1.0000 this tells us that the level is currently set to 1dB. If an incorrect command string is sent, an Nexia will respond with: -ERR A space normally proceeds the carriage return/line feed in a response to a GET command, but this space is not present in the standard ‘+OK’ or ‘-ERR’ responses.
Nexia Manual LTR Nexia software can be used to control Nexia units real time via a network. After connecting to a Nexia device, users, technicians, and designers (as determined by passwords) can access their appropriate level of control of the system. Depending on the authorized access level of control Levels, Meters, Presets, and layers can be accessed and changed.
System Control Presets Once Presets are created, Preset buttons can be placed on screen and used to easily recall different scenarios. Meters If meters are placed on screen, users can view real time Signal Present, RMS, Peak, and Logic indications.
Nexia Manual LTR HyperTerminal is a useful tool that comes with Windows® and can be used for RS-232 purposes. Simply open a HyperTerminal session by going to: Start> Programs> Accessories> Communications> HyperTerminal. Enter a name for your connection and click ‘OK’. Under the pull-down menu labeled ‘Connect Using’ select the location of your RS-232 Comm. port. Under the Comm. port properties set it to 38400, 8, None, 1, and None as shown below. Now HyperTerminal is ready to use.
System Control Windows® is a registered trademark of Microsoft Corporation. IP Address Commands Nexia has some useful IP and reset tools that may be useful when returning to older systems for service work. Nexia will automatically output its IP Address through the RS-232 port when it is powered up and functioning. Simply have a straight through RS-232 cable connected to Nexia and a PC with HyperTerminal running. When Nexia is powered up it will print the data in the HyperTerminal screen.
Nexia Manual LTR If a Nexia does not have a system loaded into it, you can set the IP Address via the RS-232 port. Example: SET 0 IPADDR 192.168.1.101 . If there is no NEX file in the Nexia, and the command is typed correctly, Nexia will send back a ‘+OK’ response. You will need to power cycle the Nexia for the new IP Address to take effect. As stated above, Nexia will output the IP Address when powered up, or you can use the GET IPADDR command mentioned above.
