RS232 Command Structure
RS232 commands sent to the VS-560 consist of four bytes: a start character, an address character, a
command mode character, and a command data byte. There is no need to send a carriage return or line feed
at the end of the message. If these characters are sent, they will be ignored. The received message structure
is summarized in the following table:
