Dear ericthegeek,

Sorry to bother you again, but I have two question waiting for your answer.
1.Get-Command:DEVICE_INFO:
The controller get all the device-info except Sensor count, no matter how many Sensor I set in my firmware, the controller always display:Sensor count:0x00.

2. Set-Command:IDENTIFY_DEVICE:
After the communication channel is setted up(Discovery process has completed),the controller send out this command periodic:

I search the RDM protocol E1.20, but find nothing about these requirement,is it different between different RDM-Controller?

Waiting for your answer,and tanks.
