3.1.2 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.
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.

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.
