INTER-M CD Player Remote Control Protocol

Model : CD-610

1. Outline

This document is remote control protocol description for using Inter-M CD player CD-610 with RS-232

port. Protocol is consist of two protocol, control signal and condition reply protocol. If control signal

protocol which is defined in this document is transferred to RS-232 port of CD-610, CD-610 is

functioned by control signal. When the status of operation is changed, CD-610 send the status reply

protocol to external controller. External control system receives this signal with showing its status on

display and confirm whether it is work properly or not. Status Reply signal protocol can be sent when any

buttons are pressed on CD player, remote controller is working, controlling with RS-232 protocol.
