Audio Control and Tone (ACT) Module
23-9
Controlling the Module
The RTU (or PC) is interfaced to the ACT via the RS232 port. The communication parameters
of the RTU (or PC) port must be set to: 9600 BPS, 1 stop bit, no parity.
The ACT is operated using a simple instruction set. Each instruction must be sent twice. If the
second instruction sent does not correspond to the first, that instruction is rejected. When the
ACT recognizes a valid instruction, it echoes an acknowledgement. While the module is
playing a stored audio signal, the instructions should be sent only once.
