Firmware on CM9001/A - cannot upgrade - cc_uk - 06-17-2026
I have a separate thread on SCS on a CM9001/A
In trying to troubleshoot this I wanted to try older firmware on the CM9001/A to determine if SCS used to work.
I ran into problems - I downgraded to ULTA 7.252. SCS still didn't work, but found I was then unable to upgrade again to 8.034. I got a message to say that the firmware did not match the system type.
after a reset the CM9001/A no longer responds - ONLY the right hand red LED of the bank of 4 LEDs is lit (ID0?), ie to the immediate right of the ALM LED.
I am assuming either the board is faulty or the FW is corrupted. I then tried to upgrade with the firmware upgrade cable, but noted that a CM9001/A needs a UCM/USB and not ETH03.
Since I don't have a USB module I will have to order one, though Laser do not appear to have them in stock. Before I order one on back-order through them please could you help me with advice on whether you think this is likely to work or is this CM9001/A faulty?
