Issue:
For PowerMatch amplifiers with firmware version 2.x, when trying to update firmware in ControlSpace Designer 5.12-5.14, the update can fail.
If a PowerMatch amplifier already has version 3.x installed, this should not be a problem.
Note: New PowerMatch amplifiers contain firmware version 2.11.
Workaround:
If updating from version 2.x to version 4.x, the workaround is as follows:
First, update the FW using the firmware file of "v3.920" which is contained in CSD 5.11.
Second, update the FW using the firmware file of "v4.012" which is contained in CSD 5.14.
A fix is being implemented in the next available version of ControlSpace Designer (5.14.1)
