6.7. COMMUNICATIONS
The object of this test is to check the communication ports of the relay (PORT1, PORT2 and PORT3). To do this
it is necessary to use a computer and the communications software GE_LOCAL. Figure 7 shows the series cable
and connection accessories necessary to establish the connection between the PC and the relay. Figure 8 shows
the cable and connectors necessary for remote connection (by MODEM) through PORT3.
The PC communication parameters necessary to match the relay default setting parameters are:
Relay number: 1
Remote port speed: 19200
Local port speed: 19200
Remote stop bit: 1
Local stop bit: 1
By using GE_Local communications software establish the connection and check that the relay communicates
through the three communication ports. Repeat this test with different baud rates and different power supply
voltages.
