Criteria for Selecting Cables
Selecting Cable Types
Select the cable type using the following items as conditions.
Note
Bit Slaves come with a Flat Cable already connected. If this cable is removed,
the Unit cannot be connected.
Using Different Cable
Types
The same type of cable must be used for all lines downstream from the Mas-
ter Unit (i.e., the trunk line and branch lines, sub-trunk lines and their branch
lines, and branch lines and sub-branch lines must use the same type of
cable).
When Repeater Units are used, however, different cables can be used for the
trunk line and sub-trunk lines, and for sub-trunk lines and sub-trunk lines,
above and below a Repeater Unit.
Note
Round cable I, round cable II, Flat Cable I (Standard) and Flat Cable II
(Sheathed) are treated as different types of cable.
Restrictions in
Distance between
Cables of Multiple
CompoNet Systems
When using more than one CompoNet System with Flat Cable I or II, opera-
tion may be unstable due to interference. To prevent this, the Flat Cables for
the different CompoNet Systems must be separated from each other by at
least 5 mm.

Application
• When using com-
mercially available
cable is desirable.
• To provide commu-
nications power
separately.
