4.2.5 STARTUP AND COMMUNICATIONS CONFIGURATION

1. Connect the computer running the 750/760PC software to the relay via one of the RS485 ports (see Section 3.2.10:

RS485 and RS422 Communications on page 3–16 for details and wiring) or directly via the RS232 front port.

2. Start 750/760PC. When starting, the software attempts to communicate with the relay. If communications are success-

fully established, the relay shown on the screen will display the same information seen on the actual relay The LED

Status shown will also match the actual relay when communications is established.

3. If 750/760PC cannot establish communications with the relay, this message will appear.

4. Click OK to edit the communications settings (or alternately, select the Communications > Computer menu item at

any time). The Communications/Computer dialog box will appear containing the various communications settings for

the local PC. The settings should be modified as shown below.

preferred when the software is being used without an attached 750/760 relay.
