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.
