Interfaces Common to the Converters
The RS485 equipment interface and the operator serial I/O interface found on the converter
hardware both play a role in the operation of the switch and are included here for continuity. For
further information, please refer to the converter manual for more information on these two
interfaces.
2.4.6
Operator Serial I/O (J8 on Converter Rear Panel)
Through the Operator Serial Port, the operator can gain access to all of the control features of
the converter. This enables the remote operator to configure the switch, set the gain and
frequency of the converter and interrogate status of the converter.
The Operator Serial Port is a DB 9-pin female connector at the rear of the converter. This port
provides serial interface that can be configured as either a RS232, RS422 or RS485 interface.
This port allows the user to remotely control all of the features outlined in the Serial Protocol
(Appendix B). The serial port comes configured as an RS-232 Serial port for DCE unless
indicated otherwise. The pinout of the D sub 9-pin socket connector configured for RS232 or
RS422/485 is as follows:
