The RS232 parameters may be defined using the CONFIG menu.
Baud rates (transfer speed) may be set to 4800, 9600 or
19200bps. It is also possible to set an ‘address’ to facilitate
connection of up to 99 AR8600 to a single port for custom
operation, the addresses may be set between the limits of 01 to
