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

3.1.2Installing 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.

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 2 (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 moderate and even pressure should be sufficient to seat the module. 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 CONNECTING TO THE 10BASE-T ETHERNET PORT

The RJ-45 Ethernet port on Model IM1/I is designed to connect directly to a 10BaseT network. Figure 3, below, shows the 10BaseT RJ-45 port pin description. You may make connections up to 330 feet using Type 4 or 5 cable.

4.2.1 Connecting the 10Base-T Ethernet Port to a Hub

The Model IM1/I 10Base-T interface is configured as DTE (Data Terminal Equipment), just like a 10Base-T network interface card in a PC. Therefore, it “expects” to connect to a 10Base-T Hub using a straight-through RJ-45 cable. Use the diagram below to construct a cable to connect the IM1/I to a 10Base-T Hub.

IM1/I		10Base-T Hub
RJ-45 Pin No.		RJ-45 Pin No.
1	(TX+)	1	(RX+)
2	(TX-)	2	(RX-)
3	(RX+)	3	(TX+)
6	(RX-)	6	(TX-)

4.2.2 Connecting the 10Base-T Ethernet Port to a PC (DTE)

The Model IM1/I 10Base-T interface is configured as DTE (Data Terminal Equipment). If you wish to connect the IM1/I to another DTE device such as a 10Base-T network interface card in a PC, you must construct a 10Base-T crossover cable as shown in the diagram below.

IM1/I		10Base-T DTE
RJ-45 Pin No.		RJ-45 Pin No.
1	(TX+)	1	(TX+)
2	(TX-)	2	(TX-)
3	(RX+)	3	(RX+)
6	(RX-)	6	(RX-)
