Using Connection Cables
This section describes how to connect modules using connection cables in a CC-Link/LT system.
• The cables can be wired regardless of station number order.
• Install the master module on either end of the trunk line.
Connect a terminating resistor on the master module side within 20cm from the master module.
• Connect terminating resistors to the both ends of the trunk line of CC-Link/LT without fail.
Connect terminating resistors to the both ends of the trunk line in a CC-Link/LT system.
• For contact information on connection cables, connectors, and terminating resistors, visit:

Calculate the number of required connectors with reference to the following example.
When using a dedicated flat cable for a trunk line and VCTF cables for branch lines

The number of required connectors are as follows:
1) Dedicated flat cable connectors (number of
2) VCTF cable connectors (number of
3) Terminal blocks (number of
