CABLING

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).

RJ-45 Straight-Thru:

￿	pin 1 → white / orange		← pin 1
￿	pin 2 →	orange	← pin 2
￿	pin 3 → white / green		← pin 3
￿	pin 4 →	blue	← pin 4
￿	pin 5 → white / blue		← pin 5
￿	pin 6 →	green	← pin 6
￿	pin 7 → white / brown		← pin 7
￿	pin 8 →	brown	← pin 8

		Pin	RJ-45 Straight-Thru			Pin
TX+ 1						1	RX+
TX-	2			2			RX-
RX+ 3						3		TX+
+V		4			4			+V
		5				5
RX- 6					6			TX-
+V		7				7		+V

Pins 4, 5, 7, and 8 are used to carry power to the Canopy modules.

RJ-45 Crossover:
