Address FF is a serial broadcast address. Any unit will respond to a command with an address
of FF regardless of the actual serial address set for the unit. Commands being sent to units
over Ethernet must contain an address of FF for proper operation. Otherwise a non-
matching serial address could cause the command to be rejected even though the IP address
was correct.
Command
The command is one or more ASCII characters from A to Z. A list of available commands is in
the next section.
Data Bytes
Each command has a fixed number of data bytes. A response to a command may have a
variable number of data bytes. In that case one of the data bytes will signify how many data
bytes are contained in the message.
Checksum
The checksum byte is a bit wise Exclusive OR (XOR) of all the bytes, inclusively, from the
header to the ETX. For example:
02h 30h 30h 51h 03h 50h
STX 0 0 Q ETX CHK
