COMMUNICATION INSTRUCTION MANUAL
This manual contains instructions for communication functions of the ACD-13A, ACR-13A, ACD-15A and ACR-15A.
Serial communication and Console communication cannot be used together.
When performing Serial communication, remove the exclusive cable (CMB) from the USB port of the PC and
console connector of the ACD/R-13A, ACD/R-15A.
When performing Console communication, it is not required to remove the Serial communication cables.
However, do not send a command from the master side.
