Weird situation.
My 7890A stopped communication with Chemstation B.04.03 SP2 [106] Windows 7. I am getting a module not found error. I was running fine then just stopped after a reboot.
I moved the instrument to an XP laptop running B.04.03 [16]. There it ran for a while (a few days), then stopped as above after a reboot.
I created a new instrument on the XP and the instrument boots, can read the instrument parameters but won't download a method.
I can ping, and change the firmware so it looks like it is a software error. I did change the LAN cable. It is a crossover
I reloaded Chemstation outright and the online doesn't find the instrument.
I changed the logic board and reloaded the firmware A.01.16.
No change.
I tried on a windows 10 instrument in Windows 7 mode. It worked once then back to module not found.
I tried deleting the inst config files. That didn't seem to work
Then I hooked up a 6890N and have no issues with it running at all even after reboots.
So I hooked up the 7890A again. No luck
I need the 7890A running on the Win 7 computer. What is left to do.
