Upgrade information
Meter firmware
A meter that has been upgraded to firmware version 2.1.0 or later cannot be downgraded to an earlier firmware version. All subsequent meter firmware upgrades must use an upgrade file with the UPX file type extension.

unsupported file type
Do not upgrade to firmware version 2.1.0 if you need to
downgrade the meter in the future. Firmware version 2.1.0 and later
is not compatible with the previous UPG meter firmware upgrade file
format.
Failure to follow these instructions can result in loss
of firmware downgrade functionality.

Remote display firmware
The remote display firmware upgrade only applies to the PM89RD96 (96 x 96 mm remote display) with firmware version 3.x.x or earlier. The remote display must be connected to the DIN rail-mount meter, and the meter must be connected to the same Ethernet network as the computer running ION Setup.
Restart requirement
There are no manual power-down/power-up requirements for the meter firmware upgrade. Meter automatically restarts as required.
