Advance Packet Serial
Commands
The following commands are used to read RoboClaw status information, version information and
to set or read conguration values. All commands sent to RoboClaw need to be signed with a
CRC16 (Cyclic Redundancy Check of 2 bytes) to validate each packet it received. This is more
complex than a simple checksum but prevents errors that could otherwise cause unexpected
actions to execute on the Roboclaw. See Packet Serial section of this manual for an explanation
on how to create the CRC16 values.
