Diagnostic Equipment

Control Panel

The control panel is the central component of the GT1. The operating system and the app
cation programs are stored here.

43 - 04-09

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)

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 Unger or the touch pen supplied to operate the touch screen. If other
objects are used, it may damage die 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 soft¬
ware, necessitating a reinstall (use only in an emergency).

The status of the switch does not affect the charging operation.

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 batten/. A flashing orange LED signifies a discharged batten/.

Alternately flashing orange/green LED denotes that the internal battery is defective or has
been removed.

Diagnostic Equipment

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 inter¬
nal power supply.

Caution: 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 key¬
board should be configured 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.

Diagnostic Equipment

Battery

Power is supplied by the integrated batten/ when the control panel is not connected to an
external powersource. The battery must be charged to insure uninterrupted use of the con¬
trol 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. Charging
time is approximately2 hours and while the battery is being charged the "Battery" LED illu¬
minates in yellow.

To achieve the longest possible service life for the integrated batten/, it must be fully
charged, then discharged for normal use. Once a month the batten/ should be "formed"
which entails fully discharging the battery, then fully recharging it. To "form" the batten/:

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 con¬
nector 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.

Optical Testing and Programming System - OPPS

43-04-35

OPPS (Optical testing and Programming System) is a device that may be used instead of
the Diagnostic Head as a vehicle interface for either the DISplus or GT1 When used, it
replaces the Diagnostic Head. OPPS was developed to reduce the amount of time required
to program E65/E66 M OST control modules by 30-60% and to diagnose the Fiber Optic
communication systems MOST and Byteflight. OPPS can be connected into the MOST bus
and the OBD connector simultaneously.

Refer to E65 CIP PROGRAM M IN G SETUP below, for details on how to connect and make
use of OPPS forCIP programming. Each OPPS unitwill have the Network settings foryour
service workshop configured when you receive it. API International has been contracted to
perform this service:

No loading or configuring necessary upon receipt of the OPPS.

Report any problems to API @ (800) 527 - 4872 ext. 232.

/Vote; For additional details and updated information, refer to SI #B07 03 02. OPPS is deliv¬
ered with newer operating software than is available through the DISplus/GTl. Do not
under any circumstances perform an OPPS software update available in "Connection
Setup" or if automatically prompted by the DISplus/GTl software until CD32. jfan update
is performed before CD32 the OPPS will be nomopemtional and must be returned for
repair.

All OPPS units remain the pmperty of BMW of North America LLC. Centers may not sell,
transfer or assign any third party to use the OPPS and its software.

2 Carrying cases
2 OBD cables

Cabling Setups:

There are 2 different cabling setups that are addressed in this section. Each is used for
E65/E66 programming and MOST/Byteflight diagnosis. Each OPPS will require 1 Network
IP address and 1 wall mounted LAN receptacle. API has acquired the additional IP address
(es) for each center.

If upon receiving yourOPPS the workshop has a sufficient numberof LAN receptacles, use
cable setup #2. If the workshop does not have a sufficient number of wall mounted LAN
receptacles, use cable setup #1. The following is an overview of the 2 different cabling
setups.

1. Cable setup #1 This setup should be used if the OPPS is operated independent of the
workshop network.

2. Cable setup #2 This setup should be used if the OPPS is operated on the workshop
network.

20

Diagnostic Equipment

Cable Setup #1 - To be used if the network is not operational (using GT1)

This setup may be used temporarily if the network is not operative, there are not enough
LAN wall drops or network IP addresses are in conflict. The vehicle is direct wired to the
OPP5 and the GT1, which is direct wired to the printer via the USB A/B cable (1 piece sup¬
plied to every center with the first GT1 delivered). The USB printer cable can stay attached
to the printer even if the printer is working on a network. The printer configuration must be
changed to "Local printer" in the GT1.

Note: This setup requires a direct USB cable connection to the printer. This greatly limits
GT1 mobility and will not allow the update of diagnostic programs via the network, which
will be available as of the third quarter of 2002. It should only be used as an exception for
the reasons stated above. This setup may also be used for E65/E66 programming.

Instructions

1. Attach the straight adapter to the control
panel (4) LAN connector.

Note that the straight adapter stays attached
to the GT1 regardless of which cable setup is
used.

S07 02 U14

2. Attach the straight LAN cable SE (3) to the
free end of the straight adapter.

3. Attach the free end of the straight LAN cable
SE to an open LAN connection on the wall.

Wired wall LAN connections should have a
number/letter combination on them.

This number will also be on the connection
where the switching hub is located.

4. Attach the OP PS to the vehicle using the
short OBD cable P/N 663 111 (2).

5. Attach the DK LAN cable to the OPPS (1).

6. Attach the chrome connector end of OBD
cable (short) 663 111 to OPPS connector (2).

This "short" OBD cable is used for diagnosis
and for C IP programming.

The "long" OBD cable 663 112 is used for
testing optical bus systems only. The "long"
OBD cable 663 112 only transmits at a baud
rate of 10400 compared to the high speed
115K baud rate for 663 111.

7. Attach the free end of the DK LAN cable (4)
to a LAN connection on the wall. Wired wall
LAN connections should have a number/let¬
ter combination on them.

This number will also be on the connection
where the switching hub is located. Before
attaching this line to a wall LAN line make
sure that the other end of the line is attached
to the switching hub.

8. Establish communication with the vehicle via
the usual procedure. OPPS takes slightly
longer to perform a "self test" than the
DISplus/GTl head.

As stated earlier, OP PS comes with 2 OBD
cables:

“Short version" P/N 663 111 which is used for
CIP programming thmugh the OBD (2) and
MOST bus as well as diagnosis of all E65/E66
modules.

“Long version" P/N 663 112 (2) which is used
for Optical module and bus testing of modules
located a distance from the vehicle OBD con¬
nector such as in the vehicle trunk.

The long OBD cable 663 112 only transmits at
a baud rate of 10400 compared to the high
speed 115K baud for 663 111.
