5. DATA LINK CABLE WIRING
5.1 Wiring Precautions
When using existing CC-Link dedicated cables, rewire the system using
communication terminal block for the AJ65SBT2B-64RD3.
5.2 CC-Link Dedicated Cable Connection Method
The following shows how to connect the AJ65SBT2B-64RD3 to a
master module and a remote module with CC-Link dedicated cables.
Figure 5.1 Connection of the CC-Link dedicated cables
5.3 Connection of Terminating Resistor
The AJ65SBT2B-64RD3 stores the terminating resister of 110
,
so
there is no need the external wiring
(1) Precautions
(a) Move the L TER. switch until it clicks.
(b) Make sure that between DA and DB is high resistance (when
the L TER. switch is off) or is 110 (When the L TER. switch is
on) with a tester before wiring the system with CC-Link
dedicated cables.
(c) The built-in terminating resistor cannot be used in the following
cases. Wire a terminating resistor (110 or 130 ).
• A CC-Link system is configured using CC-Link cables of
130 .
• The AJ65SBT2B-64RD3 may be replaced during data link.
