Note: When the power supply receives a frame command, it will check the frame
command, if the check sum is correct, then it will return to 0x80, if there is
any error on setting parameter or over parameter, then it will return to 0xA0,
if the command wasn’t executed, then it will return to 0xB0, if the command
isn’t effective, then it will return to 0xC0. Or otherwise, it will return to 0x80.
Note: The local keys on the front panel are not allowed to use when the power
supply is in remote mode. If the local key was enabled, user can press the
numeric key 7 to change the remote mode to front panel operation mode
and all local keys will work.
