Quick Start Guide
PXL-250
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
1
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 2 for your system (1 phone line for the modem connected to
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/
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 3
• 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.
