I can't remember if the first 6890Ns were 10MB or 100MB communication cards but it could be the LAN port or the communication card is going bad. Does that one have the Jet Direct card or is it a built in type of connection?
This is a unit with a direct connection.
Interesting development since I posted this yesterday - this instrument and its PC runs off the same switch as another GC-MS and PC. The other instrument has no issues communicating. When I put the problematic instrument on its own switch, the comms no longer drops out.
For clarification - in my earlier post I'd said I'd already swapped out the switch, but what I meant was that the existing switch was working just fine with another instrument, so I'd assumed it wasn't likely to be the cause of the issue. Sorry for the error!
For some reason then, the 6890 doesn't like that switch, even though it's of a similar vintage. Changing the port on the switch and the cable makes no difference. The other instrument and the MSD and PCs on that switch all talk fine.
With this in mind, it wouldn't surprise me if the 6890 has a 10 Mbit/s-only card in it and what I thought was a fault condition may just be due to the fact that it's older.
