Cat 5e Cable Subnetwork Data Bus
The Cat 5e Cable subnetwork data bus is used to connect compatible room devices (
)
to any Distech Controls ECB/ECL series controller. See
Subnetwork Module Compatibility and
on page 71 for a list of compatible extension / expansion modules.
Cat 5e Cable Subnetwork Data Bus Cable Requirements
The Cat 5e Cable subnetwork data bus uses commonly available Cat 5e structural cabling fit-
ted with RJ 45 connectors. If you make your own patch cable, use Category 5e cable and
crimp the RJ 45 connectors at both ends of the cable either as T568A or T568B.
Never connect an IP (Ethernet) network to the SUBNET PORT connector of a con-
troller or RJ 45 connector of a room device. Equipment damage may result.

Cat 5e Patch Cable with RJ-45 Connectors (standard
straight patch cable)
RJ-45 Pin Configuration
Four (4) pairs required. Straight-through wiring. Crimp con-
nectors as per T568A or T568B (both cable ends must be
crimped the same way).
