NETWORK WIRING
ISACC units may be connected in a network using as few as two units and as many as 16
units. The units are connected together using 2 conductor twisted pair cable (Belden 9841 or
equivalent) to the networking terminal block (also called a port) labelled RS485. The 2-
position RS485 terminal block is positioned next to the RJ11 phone jack on the circuit board.
