When i request PowerInfo from my devices, some of them doesn't response.

I found that for the devices that didn't response, the checksum was wrong:
sendstring (without checksum):
0012000D6F0000C3A6FC(20)
generated checksum for the above string:
FC0A(4)

Combined send string is:
0012000D6F0000C3A6FCFC0A (24)

sendstring (without checksum):
0012000D6F0000D3198D(20)
generated checksum for the above string:
1BE(3)
Combined send string is:
0012000D6F0000D3198D1BE (23)

The last string is 1 char to short and so i got no response from the circle.

Whats happening here?
