8.5 HARDWARE CONFIGURATION
The figure below shows the required connections and equipment for the RS485 rear terminal interface. The
interface consists of the following:
1. GE Power Management F485 RS232-to-RS485 converter.
2. A standard “straight-through” serial cable connected from your computer to GE Power Management F485.
The converter box end should be DB-9 male and the computer end DB-9 or DB-25 female for COM1 or
COM2 respectively.
3. Connect shielded twisted pair (20, 22 or 24 AWG) cable from converter box to the 269 Plus rear terminals.
The converter box (+, –, GND) terminals are connected to terminals 47, 46 and 88 respectively. The line
should also be terminated in an R-C series network (i.e. 120 Ω, 1 nF) at the two extreme ends of the com-
munication link as described in Chapter 4: COMMUNICATIONS.
