■TERMINATING RESISTOR
To use the terminating resistor, turn the switch ON, and
OFF to invalidate.
(Factory setting OFF)
■EXTENSION MODULE
Combinations with all extension modules are available.
■STATUS INDICATOR LED
ID COLOR FUNCTION
PWR Red
Turns on when the internal 5V is supplied
normally.
RUN Red
Turns on when the refresh data is received
normally.
ERR Red
Turns on when the received data is abnormal.
SD Red
Turns on when the module is transmitting.
RD Red
Turns on when the module is receiving.
■NODE ADDRESS
Node Address is selected between 1 and 99 in decimal. The
left switch determines the tenths place digit, while the right
switch does the ones place digit of the address.
