CanServo/Protocol/V1.1

CAN Protocol Ver 1.1

• This protocol needs FW Ver 1.12+

• CAN ID
  • 0x7FF : Servo -> Host
  • 0x7FE : Host -> Servo

UID

• Message : Servo -> Host
  • ZUID, <UID : 16 byte>, <ID2 : 4 byte>, <ID1 : 1 byte>, <CAN Mode : 1 byte>
  • This message is sent periodically by the servo if either servo setting ID1 or ID2 is 0.

• Message: Host -> Servo
  • ZIDS, <UID : 16 byte>, <ID2 : 4 byte>
  • ZIDS, <UID : 16 byte>, <ID2 : 4 byte>, <ID1 : 1 byte>
  • ZIDS, <UID : 16 byte>, <ID2 : 4 byte>, <ID1 : 1 byte>, <CAN Mode : 1 byte>
  • The servo with matching UID sets ID2, ID1, and CAN Mode depending on the length of the message.

• This message is delivered using the MultiPacket method below.
