Mac:
1. We have had this issue for years. Specifically this affects AGS units. We were told that bus cables had to be a minimum of 6’ to avoid “ringing.” Later (after we purchased and replaced cables) we were told there was no foundation for this claim. 2. Some Fluke advanced testers we have looked at have a “bus health” test function. I think this is in the 125B Scope Meter and I see reference to the function with a BHT190 break out adapter. The literature indicates applications on the following bus architectures: Profibus, Foundation, Modbus, CAN-bus, AS-i bus and RS-485. I will leave it to you to research if this function would be helpful. BTW, the Scopemeter is about $3K and hard to get in a hurry. You could probably rent one. I wish you good luck in resolving your issue.

We have a site that has been giving us a lot of issues. It seems like the AGS might be dropping in and out and defaulting to "Off". It works flawlessly when we are there of course. Cables are testing fine. No other device seems to have these issues. All of these cables are factory made. Maybe there is another explanation for the AGS defaulting to "Off". Thanks in advance for your help -- Mac Lewis "Yo solo sé que no sé nada." *-Sócrates*
