CMB16D QC Loosing LOR signal

OK, I need some ideas on what is happening to my CMB16D QC DC LOR unit. I am loosing the LOR signal intermittantly during the show. I have tried the following. New Cat5 cables,reset the unit,tried RJ11 jacks,bypassed the unit and the problem did NOT follow, I have 3 units  and I switched the outputs from a working unit to the problem unit and visa-versa and the problem remained with the problem unit. I have checked the sequences to make sure it was OK as well. The last thing I did was replace the unit with a NEW unit and the problem remains!!! The only thing I haven't replaced is the power supply! I am stumped. Anyone?

If it's happening with a different controller, I would suggest trying a different power supply since you said you replaced the cat5 cables and bypassed the unit.

What kind of power supply are you using? Pic and info would be helpful.

If I read you right. The problem is only on the one controller, no matter what you do. I dont have my unit in front of me right now (wonder why that is? LOL). If the communication chip is in a socket. I would lift it a little and re-seat it. Sounds like the comm chip is acting up. This would be where I would focus per your trouble shooting thus far.

What is your problem with my answer? AS you both noted that the intermittent problem is only on the one controller. So, I said that maybe the problem is with the comm chip on that board. Would not a bad comm chip or its connections cause this problem?

 

How do you find fault with what I said? I did not suggest a comm cable. I did not suggest a RJ-45 jack, cause if it was either one and you physically moved controllers around then the problem would effect a different controller. And your suggestion of a power supply is not valid, unless you moved it too with the controller. Remember, you said you moved the controller, not both controller and power supply. Sorry I dont read minds so I have only your own words to go by. Yes if you moved the power supply with the controllers, there is a chance that it too could be the problem.

Max-Paul, the problem was the same with TWO controllers. Not ONE.

As quoted "The last thing I did was replace the unit with a NEW unit and the problems remains!!! The only thing I haven't replaced is the power supply."

I'm not knocking your thoughts at all.

My friend Max-Paul,

Please spare your toes... I too lock on single words to bypass the next.

I want to add that your suggestion of the comm chip does warrant a good cause and check for problems such as this.

Walk on all 10 my friend and be proud!!! :)
