Patton electronic IM1/I4 user manual Installing the New QuickConnect Module

4.1.2	Installing the New QuickConnect™ Module
1)	Make sure the power switch on the base unit is off. Leave the
	power cord plugged into a grounded outlet to keep the unit
	grounded.

4.2 CONNECTING TO THE 10BASE-T ETHERNET PORT

The RJ-45 Ethernet port on Model IM1/I4 is designed to connect

directly to a 10BaseT network. Figure 5, below, shows the 10BaseT

RJ-45 port pin description. You may make connections up to 330 feet

2)	Hold the module with the faceplate toward you and align the
	module with the guide slots in the rear panel of the base unit.
3)	While keeping the module’s faceplate parallel with the base unit
	rear panel, slide the module straight in–so that the card edge
	contacts line up with the socket inside the chassis. Figure 4
	(below) shows how a Quick Connect Module plugs into the rear
	of the base unit.

NOTE: The card edge connector should meet the socket when it is almost all the way into the chassis. If you encounter a lot of resistance, remove the module and repeat steps 2 & 3.

4)With the card edge contacts aligned with the socket, firmly seat the module by using your thumbs to apply pressure directly to the right and left edges of the module faceplate. Applying mod- erate and even pressure should be sufficient to seat the mod- ule. You should hear it “click” into place.

5)To secure the module in place, push the thumbscrews into the chassis and turn the screws clockwise to tighten.

4.2.1 Connecting the Hub Ports to Workstations

The Model IM1/I4 10Base-T hub interfaces are configured as DCE (Data Circuit Terminating Equipment). Therefore, it “expects” to con- nect to a 10Base-T workstation using a straight-through RJ-45 cable. Use the diagram below to construct a cable to connect the IM1/I4 to a workstation.

IM1/I4		10BaseT Workstation
RJ-45 Pin No.		RJ-45 Pin No.
1	(RD+)	1	(TD+)
2	(RD-)	2	(TD-)
3	(TD+)	3	(RD+)
6	(TD-)	6	(RD-)

4.2.2 Connecting the Hub Ports to a Hub (DCE)

The Model IM1/I4 10Base-T interface is configured as DCE (Data Circuit Terminating Equipment). If you wish to connect the IM1/I4 10Base-T ports to another hub (or a 10Base-T port that “looks like” a hub), refer to the diagram below to construct a 10Base-T “crossover” cable.

IM1/I4		Hub
RJ-45 Pin No.		RJ-45 Pin No.
1	(RD+)	1	(RD+)
2	(RD-)	2	(RD-)
3	(TD+)	3	(TD+)
6	(TD-)	6	(TD-)
