Vehicle Data Recorder
Access to VDR stored data and programming is password protected. All
communications with the VDR are accomplished using HAWK software. HAWK
software is loaded on a laptop or personal computer and provides the interface to change
programming in the VDR, update VDR programs, or access data stored in the VDR.
The connection between the VDR and HAWK is made one of two ways:
1. Wireless technology with the data collector or the wireless interface module
2. A cable connected to the VDR USB connector.
Default Prole
The default VDR prole is programmed at the factory. Seat and belt inputs
(connectors J1 and J2) and the seat conguration for display on the seat monitor display
are set (Refer to Wiring Section). The VDR prole can be changed using the OEM
HAWK program.
OEM (or Dealer) Using HAWK Software
An OEM (or dealer) gains access to the VDR using the OEM user name and
password. If needed it is used at the time of installation to update rmware, change
factory default congurations, or for testing/maintenance. This password does not
provide access to user information or saved data. Refer to the OEM Guide (SBA2EM)
for complete information.
Wireless VDR
To establish communications between the data collector or the wireless interface
and the VDR, access to the inside of the vehicle at the seat monitor display is required.
The SILENCE button on the display must be pressed for HAWK software to connect
to the VDR. The VDR in the vehicle where the SILENCE button is pressed is the only
one that communicates with HAWK software.
When HAWK connects to the VDR, it validates that the wireless communication
is working.
USB Connector
Some VDR models have a USB port that allows for a direct connection to a laptop
or a personal computer running HAWK software. (All stored data and programming
is password protected.)

SBA1HM Rev120113
15
LEDs
The VDR has two status LED indicators. Operation of the VDR is automatic.
STATUS POWER LED
This LED is on when the VDR has activity on any VDR input. When the VDR
is in sleep mode (inactive) this LED will blink. The VDR is connected to the battery
and always has power.
STATUS CAN BUS LED
This LED is on when ECM data is active on the vehicle CAN bus.
External Alarms
There are two (2) alarm outputs from the VDR SIGNAL I/O connector (refer to
Wire Section).
Alarm 1 Visual
The alarm is activated when there is a seat violation (seat occupied, seatbelt open
or improper sit-buckle sequence). This pin provides a ground when there is an alarm
condition (300mA maximum).
Alarm 2 Audible
This alarm is activated when there is a seat violation and the VDR detects a
vehicle speed greater than 5 mph. Pressing the SILENCE button on the display
module cancels the audible alarm (it does not cancel the visual alarm or any alarm
on the display module). This pin provides a ground when there is an alarm condition
(300mA maximum).

SBA1HM Rev120113

Wireless Interface
Module
Data Collector
Wireless Communications
The HAWK data management software needs to be installed on the computer to
store, sort, and display the VDR data.
There are two ways to collect data from the wireless VDR. Use the data collector
or the FRC wireless interface module plugged into a computer USB port. When data
is collected from the VDR using the data collector, it needs to be transferred to the
computer. The data collector is plugged directly into the computer using a USB cable.
Data Collector
The data collector is a wireless device that interfaces with FRC VDRs. Before it
is used the data collector must be synchronized to the owners copy of HAWK. This
downloads the owners VDR password, the users login list with passwords, and specic
vehicle information into the data collector.
To gain access to the data collector menus, to pair the VDR or download data stored
in the VDR or update VDR rmware a user must be logged in on the data collector.
Wireless Interface Module
Installation for the wireless interface module consists of connecting a standard
USB mini-B to Type A cable between the module and a USB port on the laptop or
personal computer with the HAWK software program installed. The rst time that
the module is connected, the device driver that is supplied with the HAWK software
package needs to be installed.

WatchDog PRO Module
The WatchDog PRO is a compartment door and equipment monitoring device.
The module becomes an integral part of the FRC Seat Monitor and Data Acquisition
System when it is connected to the VDR vai the FRC datalink.
The VDR monitors and records the status of all inputs connected to the module.
The VDR provides an audible alarm output if the vehicle is moved when a
hazardous condition exists.
The seat monitor message display shows the name and location for each input
that is causing an alarm.
The seat monitor red door-open icon lights when a hazardous conditon exists.
HAWK software templates allow the names of inputs and locations to be created
or changed.
HAWK reports show past hazardous conditions by name and location with a
date and time stamp.

Install 12-Seat Vehicle Data Recorder
Wireless Interface
As with all wireless radio systems, performance and quality of transmission depends
greatly on the installation of the equipment. For best performance note the following
tips for mounting the VDR:
To get the maximum transmit distance for the signal, locate the VDR in the cab
area as high up as possible
All metal will affect the transmitted signal, it is recommended that the VDR not
be mounted inside of a closed metal compartment
The antenna must be located at least 8 inches from occupants
Install the VDR connectors up (toward the top of the vehicle) when it is mounted
horizontally
Install the VDR connectors forward (toward the front of the vehicle ) when it
is mounted vertically
Position the antenna in a vertical position when possible, otherwise it should
be folded down horizontally with the tip pointed toward the driver's side of the
vehicle
Ensure that the antenna does not touch any objects, particularly metal objects or
wires, as this will seriously degrade the transmitted signal strength.
USB Interface
Ensure there is room to access the USB port before installing.
Installation
1. Measure and mark mounting location for vehicle data recorder mounting screw
holes. Make sure there is clearance for the VDR, antenna, and cables before
drilling holes. Refer to Figure HM-8 for layout and dimensions.
2. Drill two holes for mounting screws (1/4 inch mounting hardware is
