Can anyone help with repair info for this comm module for a TDS210. I found info that it can be upgraded to a TDS2MM with the correct firmware and memory increase which could be interesting. But right now the board will not allow the scope to boot completely so something is wrong. It did boot a few times but could never comm with the serial port connected.
Looking for file tds2mm.hex (firmware for TDS2MM module)
Looking for ideas of what to check
Looking for schematics, or pictures or any help to troubleshoot board.
Even pinout for expansion connector on the TDS210 scope would be helpful.
Thanks in advance
Eric
