Installation & Setup

Attaching Serial Controllers

An external serial controller is any device that can send and receive ASCII code over an RS-232

(null modem) serial cable attached to the CONTROL port on the enclosure’s CPU. PCs are common serial controllers. Once a PC is attached to the Precis SD, the system can be controlled by running APControl software on the attached PC (see the AMX AutoPatch CD). The system can also be controlled by entering BCS commands into a terminal emulation program (e.g., HyperTerminal). For information on BCS commands, see the BCS Protocol Instruction Manual on the AMX Autopatch CD or at www.amx.com.
