Upgrading Relay Firmware

To upgrade the 750/760 firmware, follow the procedures listed in this section. Upon
successful completion of this procedure, the 750/760 will have new firmware
installed with the original setpoints.
The latest firmware files are available from the GE Multilin website at
www.GEmultilin.com.
Units with bootware versions earlier than 3.00 must be set to a baud rate of 9600
with a Slave Address of 1 before downloading new firmware. The bootware version
can be checked in the

actual value.
Before upgrading firmware, it is very important to save the current 750/760 settings
to a file on your PC. After the firmware has been upgraded, it will be necessary to
load this file back into the 750/760.
Refer to Downloading and Saving Setpoints Files on page 4–20 for details on saving
relay setpoints to a file.
Loading new firmware into the 750/760 flash memory is accomplished as follows:
1. Connect the relay to the local PC and save the setpoints to a file as shown in
Downloading and Saving Setpoints Files on page 4–20.
2. Select the Communications > Update Firmware menu item.

cancel the process. Do not proceed unless you have saved the current
setpoints.
4. The EnerVista 750/760 Setup software will request the new firmware file.
Locate the firmware file to load into the 750/760. The firmware filename has the
following format:
27 K 700 A4 . 000
5. The 750/760PC software automatically lists all filenames beginning with '27'.
Select the appropriate file and click OK to continue. This will be the Analog
Board file.
6. A second file request will be prompted. This will be for the Control Board file.
Both analog and control board files must have the same firmware
versions.
7. The software will prompt with another Upload Firmware Warning window. This
will be the final chance to cancel the firmware upgrade before the flash memory
is erased. Click Yes to continue or No to cancel the upgrade.
