CHAPTER 3: INSTALLATION ADD DEVICE TO SOFTWAREG30 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL 3-593Figure 3-62: Configuring serial communication10. Enter the COM port used by the computer, the baud rate, and parity settings from the front panel SETTINGS PRODUCTSETUP COMMUNICATIONS SERIAL PORTS menu, and the relay slave address setting from the front panel SETTINGS PRODUCT SETUP COMMUNICATIONS MODBUS PROTOCOL MODBUS SLAVE ADDRESS menu in their respectivefields.Baud Rate — Typically 19200 for RS232 and higher for RS485. Both modems need to use the same rate.Parity — Set to None if unsureBits — Set to 8 if unsureStop Bits — Set to 1 if unsurePost Terminal Window — Enable this option if you have a SEL-203x Communications Processor, such as an SEL-2030or SEL-2032. This option enables display of a terminal window to allow interaction with the other device.11. Click the Read Order Code button to connect to the G30 and upload the order code to the software. If acommunications error occurs, ensure that the EnerVista software serial communications values entered in theprevious step correspond to the relay setting values, and also ensure that the same IP address is not assigned tomultiple G30 ports.12. Click the OK button when the relay order code has been received. The new device is added to the Online Window.The device has been configured for serial communications. Proceed to the Connect to the G30 section to begincommunication.3.7.3 Configure Ethernet connectionYou connect the Ethernet cable, define a site, then add the relay as a device at that site. The computer and UR device mustbe on the same subnet.1. Connect the Ethernet network cable to the Ethernet port on the back of the device.
