Omni8C/8P/16C Serial Port Pinouts to PC or PLC 

The isolated serial port option must be specified separately when ordering your annunciator, and will be 
factory fitted before delivery. 
If fitted with the Serial Port option, the Serial connections are as follows: 
 

DB9M Pin 

RS232 

RS485

Figure 4-5 – RS232/485 Connector Pin-out (Omni8C/16C/8P). 

 
The selection of RS232or RS485 communications is done only by the way that the connector is wired. No 
other settings or adjustments are necessary. 
 

NB: Once the Serial Port (DB9) Option Board has been fitted, the Serial Jack plug facility normally used to 

configure the annunciator is disabled and configuration must then be done through the DB9 Serial Port.
