Summary

Stewart Filmscreen BRIC (Binary Reciprocal Intelligent Controller) is a masking controller for projection screens. Supports serial RS-232 control from AMX, Crestron, or other home automation systems. Control via dot-delimited command syntax (#XXYY↵) with 4addressable unit addresses (factory default 01). Channel C maps to the door and closes automatically when screen and mask are retracted.

Notes

Command syntax: #XXYY↵ where XX = unit address (01–04, factory default 01) and YY = command key. Carriage return only — not line feed. Serial parameters are fixed at 19200/N/8/1/None and cannot be changed within the BRIC. Pinout uses standard RJ45 (connector J6): TX=pin4, RX=pin6, GND=pin3/pin5, RTS=pin1, CTS=pin2, +485=pin7, -485=pin8.
