Welcome

This guide describes how to install and use the Expedience mobile subscriber unit (MSU). 
The MSU maintains contact with base stations in order to provide wireless high-speed 
Internet access to subscribers in moving vehicles, such as cars, trucks, and vans.
This guide is intended for use by professional equipment installers. Service providers should 
not attempt to install the MSU. 

Installation overview

This section provides an overview of the tasks you will perform when installing the MSU. 
To install the MSU:

1

Determine where the MSU will be mounted inside the vehicle.

2

Install the antenna in the desired location. 

3

Run the antenna cable to where the MSU is mounted and plug the cable into the MSU.

4

Determine the appropriate length for the MSU power cable. 

a If using the full length of the cable, go to step 5. 
b If you want to change the location of the fuse holder, cut the cable and use the crimps 

to insert fuse holder at the desired location on the power cable.

5

Power the MSU by preparing the cable and attaching the MSU power cable to the battery 
or to an unused, positive fuse block terminal. 

6

Ground the MSU to a screw that goes to chassis ground.

7

Connect the MSU cable harness to the connector on the back of the MSU. 

8

Connect the MSU to the laptop computer using the RJ-45 cable. 

For further information about these tasks, refer to the sections that follow.

Determining where to install the MSU

The MSU is installed inside the vehicle. Cables on a cable harness connect the MSU to a 
power source, to the frame of the vehicle for grounding, and to the subscriber’s laptop 
computer. Also, a separate antenna cable connects the antenna to the TNC antenna 
connector on the MSU. 
When choosing a location for the MSU in the vehicle, be sure the antenna cable and the cable 
harness can reach the MSU.
