5.7 ABx Fast Commands
The difference from the standard ABx are:
• The command/response packet contains the packet size
• You can include a checksum in the command
• The headers and terminator are ASCII characters
Since ABx Fast is a binary protocol, the Xon/Xoff handshake cannot
be used.
5.7.1 ABx Command Packet Structure
The command protocol is based on the following minimal packet
structure. The data field and the checksum may not be present
depending on the command type and your checksum setting.
Following a successful operation, the LRP75 will respond with the
following. The data field and the checksum may not be present
depending on the command and checksum setting.
