DO

• plan ahead to meet power and any telephone requirements2

for your system (1 phone line for the modem connected to

the host computer and one for each Primary PXL-500/PXL-510 in each network)

• mount controllers in environmentally suitable areas - they require protection from weather and from temperature/

humidity extremes

• if not using a KPS power supply, mount the controller at least 3 feet away from the controller's power supply to

prevent EMI radiated from the power supply from affecting the controller

• use the enclosure as a mounting template to mark drilling holes for permanent mounting

• consider mounting requirements - central versus distributed

- central mounting places all controllers in one location, running lengths of cables out to each door to support

readers, inputs and outputs

- distributed mounting places each controller near the door it supports running short lengths of cable out to each

door, but running a long network communication cable

• note the locations of the knockouts in the enclosures and remove the appropriate knockout for the easiest cable

routing into the controller

• route all controllers in a network in a single, continuous daisy-chain

• route cables in accessible areas for ease of maintenance

• connect all controllers to a quality earth ground3

• add transient suppression across electric devices attached to a controller output

• use an isolation relay (P/N IRP-1, or equivalent) if attaching to an elevator, a parking gate, a turnstile, or any

application using a large electric motor

• verify the controller's supply voltage is 12 VDC – long power line runs cause a drop in voltage at the end of the run

• verify proper operation of the host computer's COM port

• for a single door application, install the reader to the TB-5, "A" reader connection

• attach the reader to be used for card enrollment to the Primary controller (this reader can be used for access control as

well as enrollment, but during the enrollment process the door associated with the enrollment reader will not allow

access until the enrollment process is complete)

• If using Wiegand readers, check the voltage requirements of the reader (+5 VDC or +12 VDC at the device). A PXL-500W has a reader power voltage jumper in the lower left corner (marked JP5) - This configures to the reader port to output either 5 or 12VDC.

DO NOT

• make modem phone line connections through PBX telephone switching systems - most modems are not compatible with PBX systems leading to disconnection problems with the modem
• locate the PXL-500/PXL-510 controller near EMI sources - EMI sources can affect the performance of the controller
• use switching power supplies - they are EMI sources

• route network and reader cables beside power cables - transients on the power cables may be picked-up by network and reader cables

• stretch or over-tension cables

• route over sharp objects

• let the wires get tangled

• route controllers in a network in a loop configuration

• connect earth-ground to the network cable shield - the PXL-500/PXL-510 automatically connects earth ground to the shield at one point on the network to prevent ground loops

• use gender changer plugs when making RS-232 serial communication connections (unless you know it is a “straight-through” plug) - gender changers may have internal wiring changes that can disrupt communications

Refer to the image on page 1 for all controller wiring connections.

Note: Screws on terminal blocks must be tightened securely.

Figure 3: Earth Ground and 12 VDC Power Connections

Note: TB2 is colored red to make it easier to tell it apart from the network connector

• The "A" reader is wired to TB5.
• The "B" reader is wired to TB6.

The PXL-500W controller can be configured to accept input from single-line LED, dual-line LED, and Essex keypad Wiegand input devices (through the Doors.NET™ software).

Note: The Wiegand Reader must transfer data according to the Security Industry Association's Wiegand Reader Interface Standard (document number AC-01D-96). Keri Systems, Inc. cannot guarantee the performance or reliability of Wiegand Readers that do not meet these data transfer guidelines.

Note: All Keri Systems proximity readers use 12 VDC power while some Wiegand compatible readers use 5 VDC power. Check your reader's power requirements and verify jumper JP5 is set correctly per the Verify the Wiegand Reader Supply Voltage section on page 19.

Note: The wire colors called out in Figures 5 and 6 are industry standard wire colors. However, some manufacturers may not follow these industry standard designations. Before installation, please refer to the Wiegand device’s manual to see if the device’s wire colors follow the industry standard. If not, then match the wire’s purpose to the call outs in Figures 5 and 6 before installation.

Each PXL-500 is shipped with an installation kit including all necessary terminal blocks and transorbs. One of these terminal blocks has a jumper across pins 1 and 2. This terminal block is designated for use on TB-4. If a door switch is not used on the controller, this jumper prevents a continuous door open status alarm from being received by the controller. If a door switch is used, simply remove this jumper and install the door switch leads.

The general-purpose input is used in conjunction with the programmable input/output feature of the Doors access control software. There are three possible uses for the general-purpose input.

• the Primary controller may be figured for either Global Unlock (see figure 9) or Auxiliary A-door RTE (see figure 10)

• the Secondary unit may be figured for Auxiliary A-door RTE (see Figure 10)

Make the following connections for a Global Unlock input.

 7.0 Communication between the Access Control Network and Host Computer

Communication between the access control network and the host computer may be made via one of three ways.

• A direct connect cable between Primary controller and host computer via the RS-232 serial port.

• Use of a LAN-520 module to provide LAN/WAN Ethernet connectivity between Doors.NET and one or more PXL networks. The LAN-520 uses TB13 port to connect to the controller. For information about setting up a PXL-500 with a LAN-520 - a video can be viewed here:

• When using a LAN-520 for ethernet communication, the jumpers across JP6 and JP7 must be removed.

Note: Verify the earth ground1 has been connected at pin 3 of TB-2 before turning the power on for the first time.

Note: Do not connect the 12 VDC power supply’s terminal block output to the TB-2 connector on the PXL-500/PXL-510 controller until you have completed all the steps in section 5.1.

To verify the 12 VDC supply voltage:

1. Set the DVM to a DC volt scale capable of reading 12 VDC.

2. Turn the power supply ON.

3. Place the Red DVM lead on the power supply’s terminal block output - Pin 1.

4. Place the Black DVM lead on the power supply’s terminal block output - Pin 2.

5. Check the DVM reading. It should read between +12 VDC to +14 VDC.

6. If the DVM does not read between +12 VDC to +14 VDC, verify the power supply is of the correct voltage, verify the

cable length does not exceed 200 feet, and verify the cable gauge is AWG 18. This problem must be corrected before

power can be supplied to the controller.

7. Turn the power supply OFF.

8. Connect the power supply’s terminal block output to the TB-2 connector on the PXL-500/PXL-510 controller.

9. The controller is now ready to be powered ON.

Note: On long power cable runs, keep in mind the resistance in the cable itself causes a drop in voltage at the end of the run. The power supply must be able to account for this voltage drop.

All Keri Systems proximity readers can use from 5 to 12 VDC power while some Wiegand compatible readers use only 5 VDC. For Wiegand configured PXL-500/PXL-510 controllers, there is a warning LED on the mother board to indicate if the controller is applying 12 VDC to the Wiegand compatible reader. If your Wiegand compatible reader does operate on 5 VDC no changes need to be made; the default position for the jumper is set to 5 VDC power. If your Wiegand compatible reader requires 12 VDC, turn the controller power off and move the jumper on JP5 (at the lower left-hand corner of the controller) from pins 2-3 to pins 1-2. When power is restored, the warning LED will turn on indicating 12VDC is being supplied to the Wiegand compatible reader.

The RS-485 wiring test is provided for field testing of the RS-485 connection. The RS-485 wiring test is done in two steps. The first step tests the negative side of the RS-485 (TB-1 pin 1 and the second step tests the positive side of the RS-485 (TB-1 pin 2).

Make sure the RS-485 cable drain wire is connected to pin 3 on TB-1 on each controller in the network.

NOTE: The RS-485 wiring test will show if there are any PXL-250s that still have the R45 resistor. This resistor must be removed for the RS-485 wiring test to work properly. For information on how to test a specific controller and remove the R45 (2.2K) resistor, refer to the R45 (2.2K) Resistor Removal Application Note (P/N 01736-001).

1. Make sure all controllers are powered up.
2. Install the jumper across pins 1-2 on JP9 on the Primary controller ONLY.
3. LED11 will illuminate RED continuously (it is ok for the green LED to be either off or flashing).
4. Check each Secondary unit on the system.
   
   The following guide will inform you of that controller’s status.

• If LED11 is illuminated RED on every controller in the network, then the RS-485 negative wiring is ok.

• If LED12 is illuminated Green, then the + and - lines are reversed somewhere in the RS-485 wiring or at the

controller.

• If no LED is illuminated, then there is an open wire somewhere in the RS-485 wiring, at the controller, or the drain

wire.

• If both LEDs are illuminated on all controllers, then there is either a short in the wiring somewhere in the RS-485

wiring or at the controller, or there is one or more PXL-250s that still have the R45 resistor.

1. Once all controllers on the network have been checked and are operating correctly, return to the Primary controller.

2. Switch the jumper on JP9 from pins 1-2 to 2-3 on the Primary controller ONLY.

3. LED12 will illuminate GREEN continuously (it is ok for the red LED to be either off or flashing).

4. Check each Secondary unit on the system. The following guide will inform you of that controller’s status

• If LED12 is illuminated GREEN on every controller in the network, then the RS-485 positive wiring is ok.

• If LED11 is illuminated RED, then the + and - lines are reversed somewhere in the RS-485 wiring or at the controller.

• If no LED is illuminated, then there is an open wire somewhere in the RS-485 wiring, at the controller, or the drain

wire.

• If both LEDs are illuminated on all controllers, then there is either a short in the wiring somewhere in the RS-485

wiring or at the controller, or there is one or more PXL-250s that still have the R45 resistor.

Once all controllers on the network have been checked and are operating correctly, return to the Primary controller.

5. Remove the jumper from JP9 (be sure to keep the jumper in a place where it may be used in future tests).

6. Either perform a reset on the Primary controller, or perform an Autoconfig in Doors. The test is complete and the

system is in operating order.

Note: LEDs 11 and 12 blinking when not in RS-485 wiring test mode is normal.
