Introduction
Following the purchase of VT-2300, there will be several factors to consider prior to its installation,
including placement of the VT-2300 hardware and the selection and placement of the antenna(s). This
installation guide is designed to provide instructions for the installation of the VT-2300 hardware for
use with the NexTraq™ Fleet Tracking platform.
This document is designed for new and experienced installers and their managers to anticipate and
answer questions associated with VT-2300 installations.
This installation guide covers the following:
•Equipment and Tools
•Types of Antenna Mounts
•Placement of VT-2300
•Installations
•Troubleshooting
•Appendices covering installation of available peripheral devices
VT-2300 Hardware
The VT-2300 consists of a nylon plastic engineered housing containing the electronic components.
Additional equipment includes a separate power connection cable and a modular cellular GPS
antenna.
Specifications for the VT2300 can be found in Appendix A.
The VT-2300 is powered by an external power supply; vehicle power (12-24 volts). The device is
designed to be installed in the vehicle’s cab.
The unit is not waterproof or dustproof, nor is it designed to be placed near or on heat-generating
sources (ex: in the engine compartment, attached to the heater).

External mounting tabs are provided that allow the VT-2300 to be secured to the chassis of the
vehicle. If you are replacing a Wahoo 2 or VT-2200, the VT-2300 will fit in the area you have the
previous unit secured. Additional equipment is required to properly mount the VT-2300 hardware and
is provided in the installation kit for each VT-2300.
The VT-2300 connector configuration is composed of unique connectors to eliminate the chance of an
installer incorrectly wiring the unit. Five connectors make up the VT-2300’s configuration: power,
GPIO, a serial port interface, GSM antenna connector and GPS antenna connector.

Power Cable Diagram
Fig. 3 Power Cable Description
The 4 pin power cable is the only harness needed if install requires ONE positive input sensor / GPIO1
(in addition to normal 3-wire install).
PIN2 (green wire) will be covered by heat shrink. Installer will need to cut back heat shrink to expose
for sensor install.
NOTE: While the power cable is backwards compatible with the VT-2200, PIN2 (green wire) is not
functional on VT-2200 devices.

VT-2300 Adapter Cable Diagram
Fig. 5 VT-2300 Adapter Cable Position
Each wire on the VT-2300 Adapter Cable will be part of a connector. Wires can be cut from a
connector when necessary for sensor installs.
PIN2 is Negative Input Sensor1/GPIO2. PIN3 is Negative Input Sensor 2/GPIO3. PIN4 is Sink
Output/GPIO4 and is used for Starter Interrupt.
NOTE: PIN configuration of the VT-2300 Adapter Cable has changed from VT-2200. PIN1 now
handles 1-Wire® data including Driver ID and Temperature Sensors. (The positive input/GPIO1, PIN1
on the VT2200 Adapter Cable, has moved to PIN2 on the power cable.)
WARNING:Do not connect a wire with voltage to PIN1 (Green). This will damage the 1-Wire device.

Sensing Probe (Black/Green)
Four PIN connector Used with Driver ID Key Fob Buzzer, LED, or any other
output (Yellow/Blue/Orange-White)
Three PIN connector Used with two inputs and one output (Blue-White/Black)

Antennas
Among all installation variables, antenna location has the greatest impact on the performance of the
radio module. Great care should be taken before installing the antennas. The standard antenna type
used for the VT-2300 is a combination antenna in the style of either a blade or a puck. Two FAKRA
connectors provide connection for GPS (blue) and GSM (violet).
Fig. 7 – Combo Blade Antenna
The combination antenna combines the cellular and GPS antennas into a single antenna package. The
combination antenna can be mounted on glass, on the dashboard or as a covert installation.
