I have an A/B SLC 5/03 1747-L532 that I'm trying to upgrade. The OS on it was erased and I finally got the firmware update ROM. The battery on this unit died and I havn't replaced it yet. I just took it out.
When I put the upgrade in, it appears to download sucessfuly.
The problem is that when I remove the upgrade and cycle the power, I get a fault and I can't communicate with it at all. The fault code is
FLT, FORCE, DH485 then FLT, FORCE, DH485, RS232, BATT.
It alternates those 2 sequences. Could the lack of battery be causing this or is it something else? I just spent $150 on this stupid upgrade and its still broken.
