Thank you in advance for reading.
Having a problem reprogramming a new OEM TAC 20 CPU board. The laptop won't communicate with the board to reload the software. Pulls up a "Node is not online" error. Have tried to transfer eeprom, but the files emailed from Thyssen aren't eeprom files, they're .dat files, and the IMS program doesn't recognize them as eeprom, which they may not be anyway. The laptop recognizes the #1 elevator on the duplex and can transfer files back and forth, but it doesn't connect properly to the #2 elevator(2 stop duplex). I know it connects because the reload button becomes available when I plug it in, even though it won't allow me to reload the files.
Any idea where to go from here? Thanks again.

Respectfully,
