4.4 USING 750/760 PC
Connect the computer to the 750/760 via one of the RS485 ports or via the front RS232 port. Following are the
steps to begin communicating with the 750/760 using the PC Program.
1. Run the 750/760 PC Program using the icon installed during the installation process.
2. The main window will come up once the program has finished loading. The communications status of the
750/760 with the PC is displayed on the bottom right corner of the screen. If communications are estab-
lished, the relay displayed will show the same LEDs and display as on the connected relay.
3. If the software is unable to establish communications, it is necessary to edit the communications settings.
4. Select the Communication > Computer menu item to open the COMMUNICATION / COMPUTER dialog
box. These communications settings should be modified as follows:
4
• Slave Address: This setting should be the same as
• Communication Port #: This setting should be the COM port on your computer that is connected to the
750/760 (i.e. COM1 or COM2). On most PCs COM1 is used by the mouse device and so COM2 is usually
available for communications.
• Baud Rate: This setting should be the same as
• Parity: This setting should be the same as
• Control Type: Set to match the type of RS232/RS485 converter control type. If you are connected to the
750/760 front panel RS232 port, select No Control Type. If using a GE Power Management F485 con-
verter, select Multilin 232/485 Converter. If you are connected to a modem, select Modem. If you are
connected to a third party's converter box, use the manufacturer's specifications to select the appropriate
control type from the available list.
• Startup Mode: Set the Startup Mode based on user preference. In the Communicate with relay mode
the software will attempts to establish communications immediately upon startup. While in the File mode /
w default settings the program waits for the user to click the ON button before attempting to establish
communications – this is preferred when the 750/760 PC Program is being used without a relay.
