To upgrade the 489 firmware, follow the procedures listed in this section. Upon successful
completion of this procedure, the 489 will have new firmware installed with the original
setpoints.
The latest firmware files are available from the GE Multilin website at
http://www.GEmultilin.com.
Before upgrading firmware, it is very important to save the current 489 settings to a file on
your PC. After the firmware has been upgraded, it will be necessary to load this file back
into the 489.
Refer to Downloading and Saving Setpoints Files on page 4–23 for details on saving relay
setpoints to a file.
Loading new firmware into the 489 flash memory is accomplished as follows:
Connect the relay to the local PC and save the setpoints to a file as
shown in Downloading and Saving Setpoints Files on page 4–23.
Select the Communications > Update Firmware menu item.
The following warning message will appear.
Select Yes to proceed or No to cancel the process.
Do not proceed unless you have saved the current setpoints
An additional message will be displayed to ensure the PC is connected to the relay front
port, as the 489 cannot be upgraded via the rear RS485 ports.
