8. Master connection terminal [MASTER]
Connects to the C-RM500 Remote Controller to
split the control data transmitted from the C-
RM500.
9. Terminating resistance switch [TERMINATION]
Set this switch to ON when connecting the C-
RM500. However, there is a case that the switch
is used in the OFF position depending on the

10. RS-232C terminal [SLAVE/RS-232C]
Converts the data received at the Master
Connection Terminal into the RS-232C signal
level and sends out the converted signal. The
RS-232C Terminal also converts an input signal
to the RS-232C terminal into the RS-485 control
signal, and outputs the converted signal from the
Master Connection Terminal.
11. Slave connection terminal [SLAVE/A – D]
Splits an input signal to the Master Connection
Terminal into 4 and sends out the split signals.
