3. Configure Protocol & Self-test
C24 supports two protocols, Modbus RTU and ASCII, to communicate with the monitoring peripherals. Which
protocol to use is adjustable by the 2-toggle dip-switch on one side of C24 as depicted in Overview.
The external dip-switch also enters C24 into self-test whereby C24 examines itself to make sure its hardware is
working properly
