Using this switch, specify whether to hold or clear the output when an error occurs and
whether this slave station is the end station (station furthermost from the master station) or
not.

End station settings when using the CC-Link special high-performance cable
If the CC-Link special high-performance cable (FANC-SBH
made by Kuramo Denko, etc.) is used for the communication
cable and this slave station is the end station, always turn
OFF the end station setting (SW4 No. 2). Additionally, 130
Ω
-terminating resistor (1/2W), which is purchased on the gen-
eral market or supplied with the master station, is connected
to a position between the terminal blocks DA and DB of this
slave station to set the station to the end station.
When connecting a resistor purchased on the general market,
perform the insulation process so that the lead wires of the re-
sistor are not in contact with each other (short-circuit).
If the switch is set with the power
“
ON
”
, the setting contents may
not be recognized. Set the switch always with the serial transmis-
sion unit block power
“
OFF
”
.
Set the terminal resistance correctly, referring to the
“
Master Sta-
tion
”
User
’
s Manual. If the terminal resistance value and connec-
tion method are mistaken, there is a possibility that communication
errors may occur.
In connecting the externally mounted terminal resistor at the out-
side, be sure to turn the terminal station setting
“
OFF
”
.
Where the externally mounted terminal resistance is connected at
the outside, proper insulation is required to prevent the resistor lead
wire from contact (short-circuit).
