Components of the GT1

Group Tester One
Control Panel
The control panel is the central component of the GT1. The operating system and the
application programs are stored here.
Monitor
The surface of the monitor is covered by a touch-sensitive plastic sheet that senses the
pressure of a finger or the touch pen and transfers it to the system.
Note: Use only your finger or the touch pen supplied to operate the touch
screen. If other objects are used, it may damage the GT1 Screen.
Control Block
The main control block of the GT1 control panel is located under the center of the touch-
screen. It consists of 1 on/off switch, 3 LEDs and the infrared receiver port. The infrared
port is the connection to the wireless keyboard used during programming.
The On/Off switch is used to switch the control panel on and off or to initiate a forced
switch-off. If a fault occurs that causes the unit to lock-up, you can shut down the unit
by holding down the on/off button for 5 seconds. This may cause the loss of operating
software, necessitating a reinstall (use only in an emergency).
The status of the switch does not affect the charging operation.
Located on the front of the Control Panel:
- PCMCIA interface (radio card slot in
left handle)
- Monitor with touch capabilities
- Control Block
- Battery Compartment (in right handle)

The temperatureLED will glow red when the control panel is overheated. The control
panel will shut down approximately 10 seconds later. See the Owners Manual for restart
procedures.
The batteryLED will glow yellow during charging. It will switch off to signify the battery
is fully charged. It will flash yellow if excessive temperatures continue.
The operationLED will glow green when using an external power source, glow orange
when using the internal battery. A flashing orange LED signifies a discharged battery.
Alternately flashing orange/green LED denotes that the internal battery is defective or has
been removed.
Control Panel Connections

Power Supply
The control panel is supplied power from one of three voltage sources:
Internally from the battery (approximately 2.5 hours of operating time).
Externally from the bench power unit or the docking station.
Externally from the vehicle electrical system.

DVD Drive
The DVD Drive is accessible from the top of the control panel. It accommodates DVDs
and CD-ROMs for installing programs, applications or updates of the control panel.
Note: When you open and close the DVD drive the control panel must be in the 14°
inclination position as shown, otherwise the drive tray or the disc may be
damaged. The suspension system for the drive is optimized for 14°. Do not
use the DVD unless the control panel is attached to the docking station.
Docking Station
The Docking Station is intended for stationary operation, it replaces the bench power unit
and provides the power supply. The Docking Station also provides the interfaces for con-
nection to a USB device and the LAN Network.

Bench Power Unit
As an alternative to the docking station, the bench power unit may be used to power the
control panel. The bench power unit consists of the built in connecting cable on the con-
trol panel, the power unit itself and a separate power cable. When the control panel
receives power from the bench power unit, the internal battery is simultaneously
charged.
Optical Keyboard
The keyboard uses an Infrared link to communicate with the GT1 control panel. It is used
only for service programs and can not be used in place of the virtual keyboard of the con-
trol panel. The keyboard must always face the control panel when in use and must be
less than 1 meter away from the control panel (IR). The keyboard uses 4 AA batteries as
an internal power supply.
Old batteries can leak and damage the keyboard. Always
keep fresh batteries in the keyboard (or remove when not
in use).
If more than one GT1 is in use in the workshop, the optical keyboard should be config-
ured to a specific GT1 control panel as follows:
1. Press and hold the identification key while pointing the keyboard at the control panel.
2. Press a numeric key, 0-7 on the keyboard. The control panel will now respond only
to commands from that keyboard.
If necessary the identification can be changed at any time following the above instructions.
CAUTION!!!

LAN Control Panel Cable (Crossed)
The LAN control panel adapter (crossed) is approximately 30 cm long with a RJ45 con-
nector and a RJ45 socket. It is identified by a black (yellow on early units) stripe near the
socket and a label reading LAN Adapter BT X.This crossed cable is needed to be able
to communicate between the diagnostic head and the GT1.
LAN Control Panel Adapter (Uncrossed)
The LAN control panel adapter (uncrossed) is approximately 30 cm long with a RJ45
socket and a RJ45 connector. It can be identified by a gray stripe near the socket and a
label reading LAN Adapter 1:1.
LAN Control Panel Cable
The LAN diagnostic head cable is 10 meters long and has a RJ45 connector and an
orange plug connector.

MFK1 and MFK2
The MFK1 and MFK2 cables are the main leads used for measurements. They are simi-
lar in appearance, but have different measurement capabilities.
Only one cable, either MFK1 or MFK2 (visual markings) may be connected to the control
panel at one time unless a Measurement Interface Box (MIB) is used.
Both Both large positive cable ends of MFK 1 and MFK 2 include a button used to hold
the measured value on the display screen.
Multi-Function Test Cable-MFK #1
MFK 1 is used to measure:
Voltage - up to 50 Volts
Current - up to 2 Amps

Vehicle Battery Adapter Cable
The vehicle battery adapter cable is used while in the vehicle as a power supply for the
GT1. This cable does not charge the GT1s internal battery.
Ammeter Clamp with Adapter
The ammeter clamp and adapter can be used to measure the amperage of a circuit
inductively. There are two amperage clamp available: one measures up to 50 amps, the
other up to 1000 amps.

Battery
Power is supplied by the integrated battery when the control panel is not connected to an
external power source. The battery must be charged to insure uninterrupted use of the
control panel as a mobile test unit. The battery is charged automatically as soon as the
control panel is placed in the docking station or connected to the bench power supply.
While the battery is being charged the BatteryLED illuminates in yellow.
To achieve the longest possible service life for the integrated battery, it must be fully
charged, then discharged for normal use. Once a month the battery should be formed
which entails fully discharging the battery, then fully recharging it.
To formthe battery:
Disconnect the bench power unit from the control panel or undock from the docking
station or disconnect the docking station from a power source.
Fully discharge the battery, by leaving the control panel ONuntil all the LEDs are
out.
Dock the control panel or supply power to the docking station or connect the bench
power unit.
Charging is complete when the BatteryLED goes out.
Note: Always replace a defective battery with a new battery. Never operate the
control panel with out a battery (it acts as a buffer). Sudden interruption of
power my cause the control panel to loose the installed operating system.
Replacing the Battery
1. Switch off power and undock control panel.
2. Remove screw on right hand handle.
3. Pull off handle.
4. Remove battery.
5. Press down on the retainer for the connector
and carefully remove connector.
6. Connect new battery.
7. Insert new battery in handle.
8. Reinstall handle on control panel.
9. Completely charge new battery.

Control Panel
Note: The power supply to the control panel cannot be measured at the open
docking contact because the power is through-connected via a proximi-
ty switch only when the control panel is docked.
Forced Switch-Off may be used only in the case of spe-
cial faults. Continued use of this feature may cause oper-
ating system failure and device shut down. Normal shut
off is performed by pressing the ON/OFF switch for
2 seconds.
