4. CONNECTION CONNECTIONS B-61813E/03
Refer to Section 4.3, "Connecting a Distributed Link," and Section
4.5.2, "Connecting the communications cable," of the FANUC I/O
Unit-MODEL B Connection Manual (B-62163E) for details.
4.6.3 Setting with the DIP switch
In the AIF02C, distributed link settings can be made with the DIP
switch on the back of the module.
The settings and corresponding signals are shown below.
(1) EDSP (error display method selection)
Normally, set EDSP to the ON position.
(2) Q and H (communication speed setting)
Normally, set both Q and H to the OFF positions.
(3) URDY (setting of the power on/off information for the unit)
Normally, set URDY to the OFF position.
(4) R (terminating resistor setting)
The ON position means that a terminating resistor must be
installed. The OFF position means that no terminating resistor
need be installed.
When only one communication cable is connected to the AIF02C,
terminate it and the basic unit at the end of the communication
cable with a resistor.
When two communication cables are connected to the AIF02C,
terminate the basic unit connected to the end of each
communication cable with a resistor. Do not connect a
terminating resistor to the AIF02C. (Refer to Section 4.6.2,
Refer to Section 5.1.1, "DIP switch setting," of the FANUC I/O Unit-
MODEL B Connection Manual (B-62163E).
