RX375P

MOUNTING

RX375P Placement

Placement of the RX375P is crucial to the system’s operation. The

GPS engine inside the RX375P computes a position based upon

measurements from each satellite to the internal GPS antenna unit.

Mount the RX375P to the identied point of interest. When choosing

a location, make certain there is an unobstructed view of the sky

available to the smart antenna. This will ensure that the GPS satellites

are not masked by obstructions, which can potentially reduce system

performance.

To place the RX375P:

1. Mount the RX375P on, or as close to the center of the point of

measurement.

2. Position the RX375P as high as possible.

The following illustration provides an example of the ideal location for

vehicle placement.

Routing and Securing the Cables

Consider the following when routing cables:

• Power/data cable must reach an appropriate power source

• Power/data cable may connect to a data storage device,

computer, or other device that accepts GPS data

• Do not run cables in areas of excessive heat

• Do not expose cables to corrosive chemicals

• Do not crimp or excessively bend cables

• Do not place tension on cables

• Coil up excess cable in the cab of the vehicle or near the antenna

• Secure along the cable route using plastic tie wraps as necessary

• Do not run cables near high voltage or strong RF noise and

transmitter sources

WARNING! Improperly installed cables near machinery may cause

injury or death.

Mounting options

The RX375P can be mounted in several ways: Magnetic Mount,

Surface Mount or Pole Mount.

Magnetic Mount

The magnetic mount can be screwed into the bottom of the RX375P

and mounts to metal surfaces. A metal disc and foam adhesive are

included with each magnetic mount. Use the foam adhesive to bond

the metal disc to the desired mounting location if there are no metal

surfaces.

To use the metal disc and foam adhesive:

1. Clean and dry the mounting surface on the vehicle.

2. Remove the backing from one side of the foam adhesive and press

the metal plate onto the mounting surface on the vehicle.

3. Remove the backing from the other side of the foam adhesive.

4. Press the metal plate onto the mounting surface of the vehicle.

5. Apply rm pressure to ensure good adhesion.

6. Place the RX375P on top of the metal disc.

Surface Mount

As an alternative to the magnetic mount, the antenna is easily attached

to the surface with four machine screws (no. 8-32, not included).

To surface mount the antenna:

1. Use the templates located in Appendix C of this document, or

photocopy the bottom of the antenna and use it as a template to

plan the mounting hole locations

WARNING! Make sure the printout of the template or the

photocopy is scaled ONE TO ONE with the mounting holes

on the bottom of the antenna!

2. Mark the mounting hole centers as necessary on the

mounting surface.

NOTE: If using a photocopy of the receiver bottom, punch the

holes in the copy and use the back of the copy when marking

from the outside of the cab.

3. Place the antenna over the marks to ensure that the planned hole

centers agree with the true hole centers. Adjust as necessary.

4. Use a center punch on the hole centers in order to guide

the drill bit.

5. Drill the mounting holes with a 9 mm bit appropriate for

the surface mount.

6. Place the antenna over the mounting holes and insert

the mounting screws through the bottom of the mounting

surface and into the antenna.

WARNING! Install the antenna only hand-tight.

Damage resulting from overtightening the antenna is

not covered by warranty.

Pole Mount

The center thread of the antenna is 5/8 in (15.875 mm) for compatibility

with a survey pole (not included).
