Typical Mobile Truck Installation: Components and Connections

Installation Notes:
The mobile truck is equipped with one (or more) Series 9000 Micro Control Units (MCU’s) per the customer’s needs. The MCU is network-ready.

In the cab or another protected area of the vehicle, the cellular modem module is secured. Both units require 12-16 VDC vehicle power (under 4 amps). The cellular modem may be located behind/under a seat, or other protected area of the vehicle. One goal is to minimize the length of the coaxial cable run between the cellular radio modem and the antenna.

The cellular radio requires a coaxial cable run to the roof of the cab or superstructure where the antenna is mounted. A high-gain cellular antenna helps provide reliable cellular connections even when away from coverage areas.

Between the MCU and the cellular modem is a standard CAT-5 network cable. This cable must be oil and fuel proof or be encased in a conduit or other protective raceway. The same conduit can share network and DC power wires.

The MCU also has two wires that connect to the fuel flow pulser and the solenoid fuel control valve. The MCU provides a dry relay contact to operate the 12 VDC solenoid valve.

The MCU is weatherproof, but it is always best to provide protective cover against road dirt and dust where possible. MegaTronics has alternate sealed enclosures if required.

The cellular antenna will perform best if mounted high as possible on a flat metal surface; however, this is not required. The antenna must be protected from impact with structures. A compromise that protects the antenna may be in order. Antennas may be mounted using a magnetic mount, a drilled hole, or a right angle bracket.

The cellular radio modem provides a network (Internet) connection that can be used for other purposes on the vehicle by adding a simple network router. If added bandwidth is required to operate a computer or other equipment, a different service agreement may apply. However, telemetry or tracking devices with low bandwidth can be accommodated easily.

Alternate Enclosure
No more rust problems at seaside locations.

If the MCU will be exposed to excessive dirt, oil, fuel, dust, water, etc., MegaTrak™ offers an alternative enclosure.

Shown below, the alternative enclosure, with a rubber gasket to seal out the elements, has a replaceable door that can be opaque or clear. It can also be padlocked.
