V-Track™ Automatic Long Range Vehicle ID System
Installation Guide
1.0
System Overview
The Keri V-Track™ System
both operate in the 900 MHz band. However, V-Track™ is much easier to install and far more tolerant of different vehicle
types and metal surroundings than the toll-authority type transponder. It is also far less expensive.
The V-Track™ Vehicle Identification System consists of a directional Exciter (EX-10 - consisting of an integrated
transmitter and antenna), which sends out a uniquely coded RF signal towards the vehicle. The Transponder (LRT-5) is
mounted on the vehicle's windshield. Once the Transponder enters the field and recognizes the coded signal, it "wakes up"
and transmits its ID number via a secure RF signal to a Receiver decoder (RXR-10). The Receiver can be located up to
100 feet (30M) away from the vehicle. The Receiver is supplied in a weatherproof enclosure for direct outdoor installation
or can be placed indoors, such as in a guardhouse, close to other electronic equipment. The Receiver outputs the decoded
data to an access control unit via standard data cabling. Systems are available that output data in either the standard Keri
MS format or in 26-bit Wiegand format. A second or exit lane can be added to the system by installing a second Exciter.
This Exciter is aimed down the exit lane in the same manner as the entrance lane's Exciter.

Installation and setup is made simple and easy through the use of the LRT-5 Transponder. The LRT-5 is equipped with an
LED that flashes Red when in the coverage area of the Exciter. The flashing Red LED indicates that it is in the Exciter
field and is shipping data to the RXR-10 Receiver.

A gimbal mount is provided allowing for flexible horizontal and vertical orientation of the Exciter. Antenna horizontal and vertical radiation patterns are shown below.

External Arming Input Some installations prefer that the V-Track not be active until a vehicle approaches. The V-Track system is built with an input for external arming. This allows the use of road loops, IR detectors, pressure sensors, etc. to activate the V-Track system Antenna/Exciter. -

V-Track™ Automatic Long Range Vehicle ID System Installation Guide Exciter Electrical Installation The Exciter comes configured from the factory for single-lane or for dual-lane entrance/dual-lane exit applications. Make wiring connections as follows: • In single-lane applications only the Power (red) and Ground/Shield (black/silver) connections are made. Clip off the unneeded Green and White wires. - Page 5 V-Track™ Automatic Long Range Vehicle ID System Installation Guide Table 1: EX-10 Exciter Electrical Requirements Parameter Requirement Power Supply Nominal DC Voltage 12.0 VDC Voltage Range 11.0 VDC to 15.0 VDC Nominal Current 500 mA Recommended Power Supply 12 VDC @ 1 A or greater...

A typical mounting location is in a gatehouse for gated communities, or other enclosure, which makes it convenient to provide a data cable from the Receiver to the control unit.

Keri recommends enrolling these Transponders using the block enrollment feature provided by the Keri software (enrolling all consecutively numbered Transponders into the cardholder database at one time by number range).
- Page 10 V-Track™ Automatic Long Range Vehicle ID System Installation Guide LRT Vehicle Installation Figure 8 shows the optimal placement of the Transponder in order of signal response performance. Install the Transponder using the provided double-sided tape or Velcro™ (see Figure 9 on page 10). Ensure the label-end of the Transponder is mounted away from the rear-view mirror’s mounting post.

The EX-10 Exciter should arrive configured for your application from the factor. Labels on the Exciter cover identify individual units as either Single-Lane, Dual-Lane IN, or Dual-Lane OUT.

V-Track™ Automatic Long Range Vehicle ID System Installation Guide For Enter-Exit applications, the RS-485 electrical interface must be connected between the two EX-10 Exciters and the RXR-10 Receiver (see Figure 11 for a wiring diagram). The total length of the RS485 wiring must be less than 500 feet. - Page 13 V-Track™ Automatic Long Range Vehicle ID System Installation Guide Single-Lane Exciter Connection This wiring connection applies to systems in Single-Lane applications.

Page 20: Points To Remember
The “Range” control on the receiver has absolutely no impact on the antenna power or its coverage area. This is a receiver sensitivity control that allows the receive range to be reduced to eliminate unwanted signals from other V-Track systems in the same general area.
