The Optional RS485 
Serial Interface

Although the standard RS232 serial interface included with the 
Model DF868 is adequate for most applications, GE offers an 
optional RS485 serial interface upgrade for special situations. The 
Model DF868 is easily modified to provide RS485 communications, 
and this section describes the wiring and use of the special RS232 to 
RS485 converter.

Note:

For compliance with the European Union’s Low Voltage 
Directive (73/23/EEC), this unit requires an external power 
disconnect device such as a switch or circuit breaker. The 
disconnect device must be marked as such, clearly visible, 
directly accessible, and located within 1.8 m (6 ft) of the 
electronics console.

Interface Converter 
Mounting

A special bracket containing the serial interface converter and a three-
terminal barrier strip is mounted inside the Model DF868, just below 
the 

RS232

 terminal block (see Figure 6-1 below). The standard 

RS232

 

terminal block is wired to the input of the serial interface converter, 
and the RS-485 output of the serial interface converter is wired to the 
barrier strip.
