RS232 Command Protocol

CPU controller commands supported by the unit are defined below. All commands must be terminated with a <CR> (carriage
return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the
Command Definitions table (below). All characters in the command string are case sensitive (see Command Definitions table),
and all numbers below 10 must have a leading 0 (ex: 1 = 01).
Legend:
(All numbers must be two digits)
SA : Serial Address (01-15)
BR : Baud Rate Code
IP : Input Port (01-04)
