The following information describes the wiring standards for installing a Canopy system. All
diagrams use the EIA/TIA 568B color standard.
Currently shipping modules auto-sense the Ethernet cable type – either RJ-45 straight-thru cable or
RJ-45 crossover cable can be used to connect a network interface card (NIC), hub, router, or
switch to a module.
Earlier modules did not auto-sense. In cases where older modules are used:
• When connecting a Canopy device directly to a network interface card (NIC)
use a RJ-45 straight-thru cable.
• When connecting a Canopy device directly to a hub, switch, or router use a
RJ-45 crossover cable.
When using the Canopy AC wall adapter the +V is +11.5VDC to +30VDC with a nominal value of
+24 VDC, and the maximum Ethernet cable run with the AC wall adapter is 328 feet (100 meters).
