Terminating resistance is required at both ends of the trunk line.
This value applies when using Thick Cable for the trunk line.
If Thin Cable is used, the value will be 100 m max.

Connect external terminating resistance.
Switched using DM area setting. (Default setting: 750 kbps.)
If the number of slaves connected is 16 or less, the maximum main line length
will be 100 m max., and the maximum total branch line length will be 50 m max.
There are no restrictions on the branching configuration, main line length,
branch line length, or total branch line length. Connect external terminating
resistance to the node farthest from the master.
