Serial Communications Port
The HC-DySC serial port is a DE-9 female connector. The pin-out follows
standard RS-232 protocol: pin 2 is RxD, pin 3 is TxD and pin 5 is common
(return). All other pins are unused. Contacts are galvanically isolated from the
system power and grounds.
•
Protection: The RS-232 port is ESD-protected to 15kV.
•
Protocol: 57.6k bps, 8 data bits, one stop bit, no parity, flow control off
•
Data packets are SLIP encoded (with 2 byte length field).
•
Data accessible through this port includes load voltages, load currents,
status, and event and diagnostic logs.
•
Consult Rockwell Automation technical support for specifications to the
HC-DySC SLIP protocol.
