8RP Board
Powering Two 8RP Boards
To wire each 8RP board:
1.
Connect an 18- or 20- gauge wire from Power/Communications board J6 Pin 1 (+12 VDC) to
8RP board J5 Pin 1 (+12 VDC)
2.
Connect an 18- or 20- gauge wire from Power/Communications board J6 Pin 2 (GND) to 8RP
board J5 Pin 2 (GND)
3.
Connect the power supply (5 A or higher required) to Power/Communications board J6 Pin 3
(+12 VDC) and Pin 4 (GND).
Wiring Readers
To wire a reader:
1.
Mount the reader. Refer to the manual that came with your reader for specific mounting
instructions.
2.
Run cable from the reader to the controller. Bring each reader cable through the appropriate
knockout hole in the controller cabinet. Allow some slack wire for servicing the cables and for
plugging the cable into an adjacent slot for troubleshooting.
3.
Remove 8 inches (20.32 cm) of insulating material from the cable. Unwrap shielding and tie all
shields together. Connect the communications cable shield to the ground nut adjacent to the cable
entrance knockout of the cabinet enclosure. For more details, refer to figure
Typical Installation
Using Shielded Cable/drain Wire - Outside and Inside the Enclosure on page 20 .
4.
Place the appropriate wires to the appropriate screw terminal on the 8RP reader board. Refer to
the reader wiring diagrams in this section. Pairing of cables is very important.
Caution: The 8RP board has built-in pull-up resistors. Do not install the external
pull-up resistors supplied with Proximity Readers.
5.
Label each cable end with Controller Address Number/Device or Reader Number.
We recommend using 20-AWG shielded cable for wiring reader DOs and DIs. Use plenum-rated
cable for applications where cable is to be run above the false (suspended) ceiling in the air
circulation space.
The following cable types are recommended:
