Local Area Network: RS-485 serial port

The RS-485 serial port is located on the lower left corner of the

terminal. It is a 6 position 4-pin female port which will accept a

male RJ-11 modular connector.

The terminal can use RS-485 2-wire serial communication,

allowing up to 32 terminals to be connected to one host port. An

RS-232 port on the host is typically used in conjunction with an

RS-232/RS-485 converter to complete the connection.

Through software, the host can communicate with individual

terminals even though they are wired in parallel. RS-485 commu-

nication uses a differential bus which provides good protection

from interference over long runs of up to 4000 feet.

NOTE: When wiring a network, always follow the electric wiring

codes in your area. Typically, a teflon coated wire is required for

wiring through the ceiling. The junction box to junction box wire

shown on the opposite page is a teflon jacketed cable.
