We had a duplex thyssen endura suffer major water damage. I managed to get the slave car moving on phase 2 but I can not seem to get the cpua board functioning on the master. I've followed the manual exactly using the usb stick placing the the software in tke/update, moving the boot jumper and the reset and buttons on the board. It flashes the Morse code z like its should and after a time flashes the red led at a slow 2 pulse but the uit never comes up. Any thoughts. I've spent the last 7 days replacing boards just to get the 1 moving. The IMS will not connect without the cpua being programmed so that sucks too. I've performed this on many tac 32s no problem but this endura is different. Any help is appreciated
