Selecting Cable Types
Refer to Types of Cables on page 1-28 in 1-6-1 Design, and select applicable cables.
Using Different Cable Types
All cables downstream from the Master Unit must be the same type. That means the same type of cable
must be used for the trunk line and their branch lines; for sub-trunk lines and their branch lines; and
branch lines and their sub-branch lines.
If a Repeater Unit is used, however, cables can be different upstream and downstream from the
Repeater Unit, i.e., for the trunk line and sub-trunk lines, and for a sub-trunk line and another sub-trunk
line. Refer to the following illustration.
Note Round Cable I, Round Cable II, Flat Cable I and Flat Cable II cables are all treated as different types of
cables.
Cable Separation between Multiple CompoNet Network
When more than one CompoNet network uses Flat Cable I or II cables, electrical interference may dis-
turb stable system operation. To prevent interference, do not bundle Flat Cables from different Compo-
Net networks. Instead, separate the Cables for one network by at least 5 mm from cables for other
networks.
