In the following sections of this document, each of the commands that are used in the CHS300/400-I
converter are described in detail.
OPERATION
[01h]
R/W Byte
This command is used, in conjunction with the hardwired ON/OFF control, to turn the module
output voltage ON/OFF (Margin).
It also used to set the margin state (margin high, margin low, no margin) of the output voltage.
