Mechanical Mounting

To mount the Wireless MultiModem, do the following:
1. Obtain mounting screws (two are needed) that are appropriate for the surface on which you will
mount the MultiModem. The mounting screw on the connector end of the unit must have a
screw-head no thicker than 2 mm. The allowable thickness is limited because the screw must fit
beneath the RS232 cable. The allowable thickness of the other screw-head is not limited in this
way.

For example, one might use two 6-32 self-tapping screws 5/8” in length to mount the unit in a
truck to the wall of the cab behind the passenger’s seat.
2. Typically, the unit is mounted against a flat surface into which holes can be drilled. The
mounting holes (center-to-center) must be separated by 125mm or 4 -15/16 inches.
