Got a machine, on a patient simulator, the unit displays LL disconnected.. Changed the LL cable, LL disconnected. Changed the banana clip end, LL disconnected. Changed the CAM module, LL disconnected. Changed the CAM Cable, LL disconnected. Put the RL on the LL, unit functions normally. Thoughts?
When you say "changed the CAM Cable", do you mean the cable running from the CAM to the MAC 5500. If so, I suggest replacing or repairing the CAM board itself.
I will try a known good cam module and see if perhaps that is the problem. I have tried different cam modules, all with the same indications, so maybe (since they are on my desk) they are all broken too.
I am happy to report that the problem has been resolved. It appeared that no matter which CAM module I used, or how I hooked it up it always failed the same way. Turns out there is a problem with my patient simulator. I used a different simulator and had no problems with the unit.
I hadn't thought about test equipment being faulty.
