1: BEFORE YOU BEGIN To install an ISONAS Reader-controller unit, you must complete three key wiring tasks: 1.Supply power to the Reader-controller unit. This may be accomplished with a power feed on the Ethernet Data cable (Power over Ethernet [PoE]) or through an external DC power source (12VDC or 24VDC) 2.Wire the unit to the door’s locks and other components for physical access control. 3.Connect the unit to the data network for communication with the server/workstation host PC.

1.3: INSTALLATION LOCATION GUIDELINES When selecting the location where you are going to mount the ISONAS readercontroller, a few guidelines should be observed. 1) The reader-controller should be kept at least 2 feet from another ISONAS reader-controller, and 6 feet from any other RF emitting device. 2) Assure that the window on the back of the reader-controller’s is mounted against a reflective surface.

1.4 POWERNET CONFIGURATION The PowerNet reader-controller has a set of jumper pins that configure both its input power source, and its lock control circuit. The PowerNet reader-controller can be configured for power to be supplied to the reader-controller through the 12 conductor pigtail (either 12VDC or 24VDC) or through the RJ45 connector (Power Over Ethernet).
1.5 POWERNET READER-CONTROLLER RESET BUTTON The PowerNet reader-controller has a Reset Button located on the back. It can be used for two different types of resets. It is helpful if the PowerNet’s Ethernet cable is connected, and functioning (the amber LED is lit). Monitoring the amber LAN status LED allows you to determine the status of the reset operation. Reset CPU: Press, hold (approx. 2 seconds) and release the Reset button.
2: WIRING AT THE DOOR AND READER-CONTROLLER 2.1: POWERING THE READER-CONTROLLERS All ISONAS Reader-controller models require a direct connection to a power source. The PowerNet reader-controllers can be powered with 12 volts DC, 24 volts DC, or PoE (IEEE 802.3af) power and the supply must be regulated. Many brands of power sources work well with ISONAS equipment. For the PowerNet readercontroller, the desired input power selection is made thru the use of the jumper pins. See previous section (1.
A standard CAT5 cable is then run between the PoE source (Injector or switch) and the PowerNet Reader-Controller which will be located right next to the door. The CAT5 cable can be up to 100 Meters (328 feet) long. With one cable, you provided the required network connection and all the power that will be needed at the door site. PowerNet Supplying 12 VDC to Door Components When using PoE, the PowerNet reader can supply 0.6 amps@12 Volts of power for the external door components.
PoE Power Budget Calculations When planning an installation using PoE, you need to assure that the PoE source (PoE Injector or PoE equipped Network Switch) supplying the PoE power is sized properly for the power draw of all the doors. To do this, you total up the power draw (in watts) of the PoE connections, and compare that total power draw to the rated capacity of the PoE source. Below is a chart of expected PoE power draws of the ISONAS Reader-controllers.
Power Source PoE (802.3af) PoE (802.3af) Switchable Equipment at Power the Door (Max) 0.60 amps PowerNet (12VDC) 0.55 amps PowerNet (12VDC) EDK DC Power Supply 12 or 24 VDC DC Power Supply 12 VDC 1.0 amps PowerNet 3.0 amps (12VDC) PowerNet EDK High-Powered PoE (802.3at) 1.

2.2: WIRING THE DOORS After you connect power to every Reader-controller, the next step is to connect the wiring at each door. Wiring a door may involve connecting: An electronic door latch A request to exit (REX) like: REX Button Motion Detector An auxiliary (AUX) button Door sensors TTL lines (TTL1 and TTL2) Figure 5 shows the typical configuration of equipment at the door.
2.2.1: READER-CONTROLLER CONTROL-LEADS DESCRIPTION The reader-controller has a cable extending from its back plate that is referred to as “the pigtail”. The pigtail consists of 12 wire leads (22 awg) which are used to connect to the various components at the door location. Most installations do not require the use of all the leads. The typical usage of each available lead is shown in Figure 6. Figure 6 One of the wires is for a door sense switch.
The controllers have a lock-control circuit. This circuit consists of a form-C relay, with its “normally open”, “normally closed” and “common” contacts connected to three leads of the pigtail. These pigtail leads can be directly connected to the electronic lock to unlock the door when a valid credential is presented. There are two additional output signals called TTL1 and TTL2 that can be programmed to behave in a variety of ways. The usage of each lead will be detailed in the next few pages.
2.2.2: LOCK WIRING -- BASIC Electronic door lock Overview: If the door does not already have an electronic lock, first install the electronic door lock according to the manufacturer's instructions. Examine the lock to determine whether applying power will lock or unlock the Installation Tip door. Fail Safe: If applying power locks the door (usually magnetic locks), use the gray wire labeled (NC).
Generic Wiring, using External Power for the Lock: See Figure 7 1. The PowerNet itself is being powered by PoE. 2. Connect the positive side of the power supply to the pink (common) wire on the ISONAS Reader. 3. For a Fail Safe lock, connect the gray (Normally Closed (NC)) wire on the ISONAS Reader-controller to one lead of the electric lock. For a Fail Secure lock use the Reader's tan (Normally Open (NO)) wire instead. 4. Wire the other lead of the lock to the Black wire on the power supply.
Generic Wiring, using PoE: See Figure 8 The PowerNet supports a simplified configuration when PoE is being used to supply the lock’s power. 1. Assure that the jumpers are configured as shown: JP1: Pins 2 to 4 Or No jumper JP2: Pins 1 to 3. 2. For a Fail Safe lock, connect the gray (Normally Closed (NC)) wire on the ISONAS Readercontroller to one lead of the electric lock. See In-Rush suppressor section for more info. 3. For a Fail Secure lock use the Reader's tan (Normally Open (NO)) wire instead.
2.2.3: WIRING THE REX BUTTON The REX (Request for Exit) signal expected by ISONAS Reader-controllers is a momentary closure. You can generate this signal with a pushbutton, infrared motion detector, or other simple device. Typically the REX is placed adjacent to the door so that people can press the button and let themselves out the door without setting off the alarm. When pressed, this button tells the ISONAS Readercontroller that that someone wishes to pass through the door, and the latch releases.
2.2.5: WIRING THE DOOR SENSE Connecting the ISONAS Reader-controller to a door sensor allows our Crystal software to determine whether that door is physically open. Then the Crystal software can create alarms based on the door’s state. This wiring task is similar to wiring the REX or AUX About the Door Sense buttons. First, connect one terminal of the door sensor to the Reader's blue wire. Then connect the door sensor's other terminal to the Reader's common ground wire (black).
2.2.6: LOCK WIRING -- LOW-VOLTAGE 12VDC POWER OPTION Powering the reader-controller using low-voltage DC: Wiring DC power to a Reader-controller: Simply run the positive and negative wires from the power source to the positive and negative wires on each Reader. The example below shows the typical power connection for a reader-controller and a lock. 1. Connect the positive power from the power supply to the positive power connection (red lead) of the reader-controller.
2.2.7: LOCK WIRING -- EXTERIOR DOOR KIT The PowerNet readercontroller has an optional Exterior Door Kit (EDK), which allows you to isolate the door’s lock control circuitry on the secure side of the building. Also, since the EDK is rated for 3 amps of current @ 12 Volts, it can be used in cases where the locking mechanism requires more current than the readercontroller’s control circuit is rated for.
The 2nd example shows powering the EDK with the Reader-controller’s PoE power output, and the lock with an external 24 volt power supply. See Figure 13 Understanding the EDK’s LEDs: When the EDK Power LED is lit, it indicates that power is available to the EDK (Red LED). The EDK communication’s LED has four states: Off: No signal received from the reader-controller. Green: Signal received from the reader-controller, and valid encryption key is available.
2.2.8: LOCK WIRING -- 2 READERS TO 1 LOCK If you are wiring both sides of the door to control IN and OUT access, then you will have the special condition of wiring 2 Reader-Controllers to a single locking mechanism. If there is not a door sensor switch connected to the door, then typically you connect both reader-controllers to the door’s lock circuit.
2.2.9: USING THE TTL LEADS The TTL1 and TTL2 leads are logical output leads. In their “normal” state, there is a 5VDC potential on the leads. When the leads “activate”, this voltage potential is removed (0 VDC. These leads are typically used to connect to an alarm system. Certain abnormal conditions of the reader-controller can be configured to activate these leads. An example would be having TTL2 activate when the door is held open too long.
2.2.11: WIRING THE WIEGAND INTERFACE MODULE The ISONAS Wiegand Interface Module (WIM) allows the PowerNet to receive credential data from a Wiegand-based device, validate the credential, and then log that activity. The WIM is an in-line module that is attached to selected conductors of the PowerNet’s Pigtail. Figure 15 shows how to wire the WIM. Figure 15 Note: The WIM is easily identified by a yellow stripe The PowerNet can supply the 12VDC power required by the WIM.

2.2.12: WIRING THE DUAL-SRM The dual Secondary Relay Module (SRM) is available to enhance the PowerNet’s ability to control devices located at the door. The SRM provides a set of form-C relay contacts, which are controlled by one of the PowerNet’s TTL outputs. There a multiple options available within the Crystal Matrix software to control the TTL outputs. The SRM is commonly used to selectivity control two locks, or to control a device located at the door, in addition to the door’s lock.
Figure 17 SRM’s wiring color code Color Function Purple TTL input to SRM. Connected to the PowerNet pigtail’s Purple or Brown conductor. Black Power Ground from PowerNet.
2.2.13: WIRING THE QUAD-SRM The Quad Secondary Relay Module (QSRM) is available to allow a single PowerNet to control up to 4 locks. The QSRM is an electronically controlled 4-way switch, that directs an input electrical signal to one-of-four outputs connections. The QRM is commonly used to control multiple doors on storage cabinets or computer racks. Figure 18 shows a PowerNet and QSRM controlling four fail-secure locks.
QSRM’s wiring color code Color Function Purple TTL input to SRM. Connected to the PowerNet pigtail’s Purple conductor. Brown TTL input to SRM. Connected to the PowerNet pigtail’s Brown conductor.
2.2.11: MANAGING INDUCTIVE LOAD CHALLANGES Most door latches use a relay coil that powers up and down to open and close the door. When this happens, electricity enters the connected circuit. This problem, known as back EMF, produces network interference that usually becomes more pronounced when the device is switched off. Switching off a typical 12 VDC relay coil can produce a back EMF of 300 volts or more. If this relay is switched via an output, that voltage appears across the terminals of the output.
2.2.12: MANAGING IN-RUSH CURRENT LOADS Some Magnetic Locks with advanced quick-release circuitry will generate an initial surge of current when the lock is turned on. This surge of current can be 20 times greater than the lock’s steady state current requirements. The lock control relay is rated for 1 amp of current. This in-rush current can greatly exceed that rating, and shorten the useful life of the reader-controller. Figure 20 shows the solution to this.

3: CONFIGURING THE READER-CONTROLLER’S COMMUNICATIONS ISONAS Crystal software communicates to the Reader-controller units over the organization's data network. 3.1: ETHERNET-BASED TCP/IP READER-CONTROLLERS There are many Ethernet network topology permutations, too many topologies to cover in this guide. Here are two common Ethernet configurations used by ISONAS customers: Direct Crystal-Software to Readers: This is the simplest type of network connection.
Using Port Forwarding to reach the Readers. This is common on networks where the available number of IP addresses is limited. It can also be used when the ISONAS software must communicate with Readercontrollers on another site that is behind a network firewall. As in the first topology, ISONAS Crystal software runs on a server/workstation that is connected to a Ethernet network.
Here is an example of the ISONAS Network screen for the above configuration: Port Forwarding requires steps outside of the ISONAS software; you must configure your Router to “forward” each port number to exactly one reader. This configuration is specific to the Router that you purchase and will be defined in the vendor’s documentation. Typically the configuration is labeled “port forwarding”; however it is sometimes referred to as “gaming options.
3.2: SECURING MESSAGES ON YOUR NETWORK You can configure ISONAS Readers and software to secure each and every message to and from the Reader using Advanced Encryption Standard (AES). When you enable AES in both an ISONAS Reader-controller and the Crystal software, every message to and from that Reader-controller is encrypted. Therefore, anyone who manages to hack into your data network would still face a daunting task to decrypt the actual messages to the Reader-controllers.
