VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL DESCRIPTION SECTION 2.1: DESCRIPTION This section provides a high-level description of the transmitter’s key sections. The transmitter circuitry is subdivided into four basic stages: Ac-Dc Power Stage Control/Excitation Stage - see page 2.1.4 RF Stage - see page 2.1.5 Refer to the functional block diagram, Figure 3.1.1 on page 3.1.9. VX150 to VX2 Electrical Schematics Some descriptions in this section refer to electrical schematics (SD-#s).
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL DESCRIPTION Power Supply Interface PWB See electrical schematic Figure SD-1. The Power Supply (PS) Interface PWB (A4): interfaces between the ac input and the LVPS and the power supply. distributes LVPS voltage to the RF drive (exciter) stage and the control/monitor stage. distributes PA voltage to the RF power stage and the control/monitor stage. controls, with the controller module, the LVPS output voltage.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL DESCRIPTION Control/Excitation Stage See electrical schematics SD-1 and SD-3. The control/excitation stage performs many critical functions for the transmitter. The primary components of the control/monitor stage are the Exciter PWB (A1) and the System Interface PWB (A3). The display module (U1) uses a rotary button to navigate through the various menus. On the front panel there is a pushbutton switch (BACK) to allow the user to return to the previous menu.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL DESCRIPTION System Interface The System Interface PWB (A3) interfaces with the Exciter PWB to perform the following functions: contains monitoring and protection circuits to prevent transmitter damage under adverse or fault conditions, including high speed SWR protection and interlock/muting.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL DESCRIPTION RF Stage See electrical schematics SD-2 and SD-4. The RF power stage accepts the RF drive input and generates the final RF output. It consists of a Pre-amp/IPA (A6), Power Amplifier (A7), Exciter PWB (A1), a Low Pass Filter assembly (A9) and a Directional Coupler (A11). The Pre-amp/IPA amplifies the exciter’s RF output to the proper level required to drive the power amplifier(s). IPA/RF Power Amplifier See electrical schematics SD-12 and SD-13.

VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Figure 2.2.41: Network Settings Page All IP addresses shown are for reference purposes only Determining DHCP Setting One of the main decisions in configuring the network connection on your VX150 to VX2 transmitter is whether you set DHCP to ON or OFF.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL 3. OPERATING THE TRANSMITTER Enter the following parameters (where applicable): Mac Address - Displays a number that serves as unique network adapter identifier. This is set by the manufacturer and is displayed for informational purposes only (cannot be user set). It may be necessary to use this number to allow the AUI to access your network.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Connecting a Laptop Directly to the Transmitter If connecting to the VX150 to VX2 directly with a laptop, you must set a static IP address on the VX150 to VX2 and your laptop. 1. 2. From the controller UI’s Main Menu, go to User Settings -> Network Settings and set the IP address as follows: DHCP: OFF IP Address: 10.10.10.2 Netmask: 255.255.255.0 Set the transmitter for Remote control.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Exgine Email Server The Email Server (see Figure 2.2.42) allows you to configure email parameters (e.g., email server and port number), and is required if the notification feature is used (see Notifications, on page 2.2.64). NOTE: Nautel recommends that the following settings be entered/vetted by a qualified Network Administrator. Figure 2.2.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL 3. OPERATING THE TRANSMITTER Enter the following parameters: Email Server: The outgoing mail server. Enter the server name or IP address here. In order to enter a server name (e.g., mail.nautel.com), at least one nameserver IP address must be entered (see Network, on page 2.2.65).
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Time The VX150 to VX2 controller module’s internal clock uses an externally accessible backup battery, and therefore maintains an accurate date and time, even during power outages. The date and time needs to be set when the transmitter is first installed, or after a power outage if the backup battery has failed. You can set the date and time using the AUI (see Setting the Clock - using the AUI).
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Procedure to set up the time and date: 1. Select the Time Setup option from the left-side of the User Settings page to open a related window on the right-side of the page. 2. Enter Time and Date parameters and press Apply. Press Cancel to discard changes. Please note that Time and Date cannot be set via this menu if NTP is enabled (see Setting the Clock - Using the Front Panel on page 2-152). 3.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER NOTE: The NTP clock synchronization polling interval varies between 64 and 1024 seconds. To minimize network traffic, the interval will change depending on how much error is accumulated between polling events and will be increased if the remote NTP server becomes unreachable. The polling interval is also randomized slightly to avoid the situation where a large number of requests are always arriving at the NTP server at the same time.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Monitoring NTP Servers The NTP Server Status section displays tabular information on the NTP servers connected to the network. The table includes remote name, IP address, delay, offset and jitter. Remote Name: Displays the host name of the referenced time source. An asterisk (*) in the first column marks the reference time source that is currently preferred by the NTP daemon.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER SNMP The SNMP page (see Figure 2.2.46) provides a means to configure the SNMP agent and associated traps. Figure 2.2.46: SNMP page Configure the SNMP agent as follows: 1. 2. Enter the first five fields, noting the following: Agent Port: Enter the UDP port where the SNMP agent checks for requests. The default setting is 161. If your transmitter is behind a firewall, you must open this port to use SNMP.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL 3. OPERATING THE TRANSMITTER Trap Receiver IP: Enter the IP address of the computer to which the SNMP agent will send trap notifications. The computer must be running an SNMP application that is configured to receive traps. The SNMP agent will send trap notifications to one receiver only. Trap Receiver Port: Enter the UDP port where the SNMP agent will send traps. The default setting is 162.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER NOTE: This section contains frequent reference to Orban's Optimod-FM 5500 Digital Audio Processor Operating Manual (see the link below).

Detailed descriptions are not included in this document. Refer to the Orban Optimod 5500 manual for more information on setting these parameters.
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Figure 2.2.50: Audio Processor meter window There are two types of Orban audio processor presets: factory presets and user presets. Factory presets, designated by an 'F' in the Load or Save screens, cannot be modified. When a factory preset control is changed, a new preset is automatically created. This preset's default name will be the same as the Orban preset with an asterisk (*) prefix (e.g., * EXTREME).
VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Tab Sections The following tabs (and referenced Figure numbers) are available on the Audio Processor page.
