+---- Thread: keypad communication failure (/thread-2207.html)
- m.khairy - 03-28-2011
i have a kp04 , when i communicate it with the system the message that appear on keypad is
keypad communication failure
and the system doesn\'t work
i tested the cable , it\'s good
and isolate all i/o
however the problem is still

This message means the keypad is not communicating with Comfort either because the KA/KB wires are connected or the ID on the keypad is not set correct
If there is only 1 keypad then the ID should be 1
ie the shunts A B C should be connected
The Number of Keypads in Comfigurator should match the number of keypads in he system and each ID should be set unique

Thanks for replying
But,
The KA/KP wires are connected
i have only 1 keypad and the ID is 1
The number of keypads in comfigurator is 1
The problem is still

How long is the cable connecting the KP04 to the Comfort panel?
Try connecting them with a short cable e.g. around 1 meter and see if it makes any difference?
Could it be that the KA/KB connection is reversed i.e. KA goes to KB and vice versa?
You have mentioned the keypad ID is 1 so all shunts A, B, C, D have been ensured to be closed or shunted?
And one more thing, when the Communication Failure displayed on the KP04, what Keypad number is displayed? Is it Keypad 1 e.g. \"Communication Failure Keypad 1\" or some other numbers?

Communication Failure Keypad 1

Have you tried with a short cable?

what else is connected to KA KB? are these other modules working?
Can you connect a UCM to Comfort and communicate?
What are the state of the red and green leds on Comfort PCB

The problem was in the firmware update ,
when i updated the firmware the keypad worked correctly

I think there may have been a firmware upgrade attempted before which was not successful which caused the system to be inoperative.
