Application
System µ-com → Panel data
Panel → System µ-com data
Panel → System µ-com communication
request
System µ-com → Panel communication
request

While 65XX series is used; Normal
mechanism mute request. Set up the
shared LR with normal mechanism
request command
Panel operation control terminal.
CE when the system µ-com is re-written
SOC reset terminal
SOC stop terminal
CD disc detection terminal (8cm J only)
Other than J is not used.
CD detection terminal (Chucking detection)
CD motor control terminal
Panel mechanism motor control 1
Panel mechanism motor control 2
