PXL-250 Tiger Controller

Wiegand Compatible Readers

• five to seven conductor, shielded, stranded, wire – depending upon the Wiegand reader’s requirements

• a minimum gauge of AWG 24 is required for data transfer with a 500-foot maximum run length per Wiegand

specification

Input and Output Connections

• two conductor, stranded, AWG 22 (or a larger gauge)

NOTE: The Lock Output relay may require a heavier gauge of wire depending upon the current demands of the lock and
the length of the lock wiring run.

NOTE: If plenum cable is required, please reference the Belden plenum equivalent to the cables listed above.

3.0 When Installing Controllers

DO

• plan ahead to meet power and telephone requirements
the host computer and one for each master PXL-250 in each network)

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

Quick Start GuidePXL-250

humidity extremes

• 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 ground

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

• use an isolation relay (P/N IRP-1) if attaching to 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 master 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)

1. The wire gauge to use should be determined by the current draw requirements of the Wiegand device and the
actual length of the cable run. A +5 VDC and a +12 VDC Wiegand device must have a full +5 VDC or +12
VDC at the device (long cable runs have a voltage drop across the length of the run due to the resistance in the
cable). To ensure proper voltage is available at the device a larger gauge of wire (having less resistance) or a
power supply at the Wiegand device may be required.

2. Phone lines are only needed for remote communication between host computer and network using a modem.

3. Ground wire is green with or without yellow tracer.

PXL-250 Tiger Controller

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-250 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

• mix PXL-250s with PXL-100s in the same network

• route all controllers in a network in spur, hub, or loop configurations

• connect earth ground
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

4.3 Connecting a Keri Systems Proximity Reader to a PXL-250P

• The "A" reader is wired to TB5.

• The "B" reader is wired to TB6.

Figure 4: Proximity Reader Connections

4.4 Connecting a Wiegand Compatible Reader to a PXL-250W

The PXL-250W controller can be configured to accept input from single-line LED, dual-line LED, and Essex keypad
Wiegand input devices (through the

Doors

™ 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 most Wiegand compatible readers use 5 VDC
power. Check your reader's power requirements and verify jumper JP4 is set correctly per the Verify the Wiegand
Reader Supply Voltage section on page 21. Early revisions of the surface mount PXL-250W mislabeled the JP4 jumper
as JP5. All instructions for the JP4 jumper apply to the jumper labeled as JP5 (see Figure 1 on page 1 for the location
of the jumper).

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 callouts in
Figures 5 and 6 before installation.
