Hardware and Software Installation

You can also use a ground screw on the connector panel of the MP modem. Use a 16‐gauge wire if you choose to use a ground screw. A ground screw is not required as long as the power harness is properly grounded.

Step 2—Mount the antennas and install the cables

The MP 875 modem has one Main RF antenna connector and one GPS antenna connector. The MP 595W has an additional RF antenna connector for an AP antenna. The MP modem requires an RF antenna to connect to the wireless network.

The built‐in GPS module requires a dedicated GPS antenna or a combination antenna with cables to both the Main RF and GPS antenna connectors on the MP modem.

If you already have an MP modem combination GPS antenna, you can re‐use it with your new MP modem. This antenna has two leads—one for Main RF (TNC connector) and one for GPS (SMA connector).

Main RF antenna

Use an approved Main RF antenna to connect to the wireless network. The antenna must have 50 ohms impedance and a cable with a TNC connector, as well as the following character‐ istics:

•The total maximum gain, including cable loss, must not exceed 4 dBi (if the antenna operates on the PCS band) or 5 dBi (if the antenna operates only on the Cellular band).

•The antenna must transmit and receive on the necessary frequency bands in your coverage area. The MP modem supports these RF bands:

·HSUPA and UMTS networks:

·850 MHz

·1900 MHz
