4.0 Control Commands
Control is accomplished by sending commands consisting of ASCII characters
terminated by an ASCII carriage return (<CR>, hex 0D). In most cases, several
commands may be sent together on the same line before sending the <CR>.
However, in the case of the recall preset command, other commands may
precede it but any commands following it on the same line are ignored. A
command line will not be executed until the <CR> is received. ASCII backspace
(<BS>, hex 08) can be used to correct errors in the command line. After the
command line has been executed, a <CR> will be sent back to the host to
acknowledge completion.
Communication rate is 9600 BAUD. Protocol is 8 data bits, one stop bit, and no
parity.
5.0 Installation and Hook-up

configuration. The front of the unit has an AC power switch and a Ready light.
The light will illuminate when the power switch is turned to the on position and
the unit boots up. See Figure 6 for a typical system hook-up diagram.
