The hardware communicates over local‑area or wide‑area
networks (LAN or WAN), TCP/IP, RS‑232, RS‑485 per port,
and dial‑up communications. The system works with
existing facility communication topology to reduce
installation costs.
Each intelligent system controller (ISC) can connect to a
combination of up to 16 devices. Connect single and dual
reader interfaces, input control modules, and output
control modules to the ISC over a 4000 ft (1219 m) per port
RS‑485 wire bus. The ISC uses a 32‑bit processor to
command all downstream modules using a 38.4 kbps
communication.
