I have read through the integration specs but can't seem to find a way to query the status of the CCIs on the VCRX using the integration protocol. I have tried action code 9 (to see LED status), using ?DEVICE,46,32,9, and I have also tried using action code 35 (in the documentation this says it is a CCI status query action code) using the command ?DEVICE,46,32,33. I get an ERROR,3 on the 33 action code, and an error on the action 9 (I forget whether it was ERROR,3 or a different one).
I get messages when the CCIs open or close, but I would really like to be able to query their state. Is this possible?
