When connecting two Model 1094’s, it is necessary to use a

crossover cable. The diagram below shows how a crossover cable
should be constructed.

4.2   CONNECTION TO THE SERIAL PORT 

The serial port interface on the Model 1094 uses interchangeable

Quick Connect Modules. Each Quick Connect Module has a 50-pin
card edge connector on one side and a serial port interface on the
other. Figure 3 (below) shows how a Quick Connect™ Module plugs
into the back of the Model 1094.

4.2.1   CHANGING QUICKCONNECT™ MODULES 

When you purchase a particular version of the Model 1094, it

should be shipped to you with the appropriate QuickConnect™
Module already installed. If you need to install a different
QuickConnect™ Module, follow these steps.

Removing the Existing QuickConnect™ Module 

1. Turn the power switch off. Leave the power cord plugged into a

grounded outlet to keep the unit grounded.

2. Loosen the two thumbscrews on the module by turning them

counterclockwise.

3. Grasp the two thumbscrews and gently pull the module from

the unit. Apply equal force to the thumbscrews to keep the
module straight during the removal process.

Installing the New QuickConnect™ Module 

1. Make sure the power switch 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 Model
1094.

3. While keeping the module’s faceplate parallel with the Model

1094 rear panel, slide the module straight in–so that the card
edge contacts line up with the socket inside the chassis.

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 snap into place.

5. To secure the module in place, push the thumbscrews into the

chassis and turn the screws clockwise to tighten.

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 and 3.
