Remark
Use commercial terminating resistances of
110 Ω ± 5 % and 1/2 W.
[Resistance model name]
(Example: ERDS1TJ111 Matsushita Electronic
Components Co., Ltd.)
Use of the resistances of 110 Ω and 130 Ω
furnished with the master and local modules is
prohibited.
The method to connect the terminating
resistance across DA-DG and DB-DG is also
acceptable.
If possible, do not remove the cover of the
cable on the trunk line side.
