Canaan Avalon Privilege Mode

Hi There, i tried to enable the privilege mode, but it doens't work.

Communication is ok.
I used the diagnostic from fms (for example: [{"command":"version"}]) and socat (for exaple: echo -n "version" | socat -t 30 stdio tcp:192.168.13.20:4028,shut-none && echo)

echo -n “privilege” | socat -t 30 stdio tcp:192.168.13.20:4028,shut-none && echo
STATUS=E,When=44997,Code=14,Msg=Invalid command

echo -n “privilege|0,enable_privilege,0” | socat -t 30 stdio tcp:192.168.13.20:4028,shut-none && echo
-bash: 0,enable_privilege,0”: command not found

Any idea?

Heres my miner info:
echo -n "version" | socat -t 30 stdio tcp:192.168.13.20:4028,shut-none && echo
