1.11 Access Plus System Interface Board

The Access Plus interface board (1972-010) is piggybacked onto the main unit's Plus circuit board (1970-010). The interface
board provides additional connections to the unit for keypads, card readers and/or RF receivers using RS-485 communication
protocol.
The Access Plus system can be programmed via a PC using a network or modem connection. An RJ-45 jack (Cat5) is provided
on the interface board for network connections.

1.11.1 RS-485 8-Pin Connector Description

Use the RS-485 terminals to add up to six (6) card readers, keypads and/or RF receivers to the Access Plus system. These
devices must be wired in a daisy-chain format with a maximum wire run distance of 4000 feet. We recommend that you use
Cat5e wire for all RS-485 wire runs.
DO NOT power RS-485 devices from the Access Plus system. These devices must be supplied with their own power source.
Refer to the individual device wiring instructions for connection information and wiring guidelines for these products.
