1 Introduction
1.1 System Overview and Limitations
The LTE65 is a 4G-LTE based telemetry modem designed for real time telemetry data
transfer on racetrack. The combination of LTE65 with RaceConnect cloud provides a highly
flexible telemetry data distribution platform, where one transmitter can send to many re-
ceivers and many transmitters can send to one receiver. The usage of 4G-LTE cellular ser-
vice allows for Plug & Play operation with minimal setup. The transmitter communicates
to the data system in the car via RS232 serial or Ethernet and the receiver device is con-
nected to a computer via RS232 or Ethernet.

1.4 Annual Data Plans
Each LTE65 device requires an annual subscription to be purchased. Transmitters, receivers
and spares all must have an annual subscription for use.
The plan must be renewed on a yearly basis. You will be notified by RaceConnect when
expiration of the subscription nears. Please contact your dealer to place an order for re-
newal.
1.5 System Limitations
The system has been validated with Bosch Motorsport loggers. Third party loggers using
RS232 at 19,200, 57,600, or 115,200 baud have been shown to function, but technical sup-
port is limited.
The system has been tested with computers running Windows 7 and 10 operating sys-
tems. Other operating systems may work but are not tested and technical support is lim-
ited.
Bosch Motorsport has validated 4G-LTE telemetry access at over 60 racetracks in the USA
and Europe. However, Bosch does not operate the LTE networks and cannot guarantee
performance. If you have queries about network access at a track, you plan to test on,
please request this information from an authorized Bosch Motorsport telemetry dealer.

3.4 Safety Notices
CAUTION
Disconnect power before handling of the antenna.
CAUTION
Keep a minimum safety distance of 5 cm from the human body to
the antenna.
3.5 Antenna Installation
When installing antennas, ensure that you are not spinning the cable or antenna body rel-
ative to the LTE65. To tighten the SMA connection, only turn the collar of the cable or an-
tenna. Spinning the entire cable or antenna can lead to damage of the internal co-ax
cable of the LTE65 and reduced RF performance. It is also recommended to tighten the
SMA connections to 3 in-lbf (0.3 Nm). SMA specific torque wrenches are available from
many retailers.
3.6 Receiver Ethernet Connection
Note that an LTE65 receiver must be plugged directly into a computer and not into a
switch or router. USB to Ethernet adaptors are ok to use with the computer. When the
device is used as a receiver with an Ethernet connection it will act as a DHCP server and
assign an IP to the connected computer. The default configuration for LTE65 IP and DHCP
is 10.10.0.235/24 with a lease range from 10.10.0.65-69.
Static IP addresses are not recommended as the LTE65 receiver may not reliably detect
the IP of the connected laptop.

4.2 RaceCon
RaceCon is for configuring and calibrating with Bosch Motorsport devices. For general
RaceCon setup and usage, please refer to the DDU 9 manual on the Bosch Motorsport
website. The information below deals specifically with telemetry setup in an existing Race-
Con project.
4.2.1 Adding the LTE65
In the RaceCon project for your vehicle, insert a telemetry device from the Devices toolbox
by clicking and dragging it into the project window. Please note that in order for this ac-
tion to be available, a data logging device must first be configured in RaceCon. A window
will pop-up for configuring the device. Highlighting the Telemetry icon now in the Race-
Con project should bring up the relevant details about the device in the Properties win-
dow.If this window is not visible in your project, select View Properties.
The name of the device can be changed to LTE65 by right clicking on Telemetry in the
project tree and selecting Rename.
Either a laptrigger channel must be available in the project or the logger must be in "Test-
bench" mode, which is configured via the logger's settings pages, for telemetry to work.
For the MS6/MS7 and logger/display devices, the LapTrigger and Fuel blocks need to be
added to the project to create the channels above.
4.2.2 Communication Specific Settings
Ethernet TX Telemetry
To send Ethernet telemetry from a Bosch Motorsport device, the Ethernet telemetry fea-
ture must be active. Excluding cases where older logger firmware versions are used, Ether-
net telemetry is already enabled on Bosch logging devices.
Set Ethernet telemetry settings on the device by opening the Telemetry Settings window.

Note the following parameters and their settings
– WDServer folder – this is the folder where the “.INI” files for WDServer are stored.
Please make note of this folder path as this path will need to be referenced by WD-
Server in order to enable telemetry live viewing and logging.
– Project Key – The project key is a data security function that is used by WinDarab to
differentiate data from different users. This key should always be a 4 character hexa-
decimal value.
– Configure on Device: Select the device which will be the master for telemetry
– Type: Select your telemetry unit type
– Mode: Select Ethernet or Serial depending on your desired input configuration. Mo-
dem must also be configured accordingly.
– Baud rate: Set to desired board rate. Rate of up to 200 kBit/s is possible with Ethernet
telemetry. For serial data input, baud rates under 115 kBit/s must be selected.
– Destination IP: Do not change from above value unless specifically instructed.
– Destination Port: The logger sends for telemetry to this port. Do not change from
above value unless specifically instructed
– In a new Calibration/Measuring window, ‘telemetry_state’ should be viewed. This will
inform you about the data out streaming status.

Serial TX Telemetry
To send serial telemetry the TELEMETRY_Mode should be set to Serial. No other changes
are required or values need to be set to specific values. Baudrate can be configured based
on use case needs if required.
Note: With serial to serial configuration, it is recommended that the transmitter transmits
at 57,600 bps and the receiver receives at 115,200 bps.
Note: It is recommended to keep serial bus usage below 80 % when sending serial data.
4.2.3 Configuration of Data Stream
To configure channels to be sent over telemetry, the channels must first exist in the Race-
Con project.
To add channels to be sent over the telemetry system, double-click the LTE65 icon in the
RaceCon project window. This will bring up the LTE65 Configuration Management page.
Channels can be added by single-clicking on the data logs and drag and drop the channel
into the LTE65 window.
‘Fast’ and ‘Slow’ telemetry mode are configurable for each data channel. Shown in the
window below opened by double clicking the channel in the Telemetry Configuration
Measurement window.

Bosch Motorsport Telemetry_System_LTE65_Manual 15/28
The telemetry uses available bandwidth and channels are grouped into fast and slow fre-
quency blocks, an explanation and visual representation below:
Fast block (block 1): transferred every cycle and used for a high-frequent transmission of
channel information (e.g. speed, rpm).
Slow blocks (block 2..n): transferred every nth cycle and used for a low-frequent transmis-
sion of channel information (e.g. tire pressure, oil temperature).
Only one fast block exists, up to seven fast blocks will automatically be created by Race-
Con depending on the number and data types of channels. If the maximum bandwidth of
a block is reached, a warning will be displayed. To fix this problem you can view the alloc-
ation of the channels and data rate in the ‘Statistics’ tab of the Main Area.
4.3 WDServer
WDServer is used to capture data streaming from transmitters and convert to WinDarab
file format; WDServer also creates a log of the data received over telemetry.

4 | Tools
16/28 Telemetry_System_LTE65_Manual Bosch Motorsport
4.3.1 Settings
Settings are selected by clicking the settings button at the top of the WDServer window.
Under the “Common” tab, choose directories where WDServer can store its temporary
files and log files. These are created during telemetry reception and can be used to help
diagnose issues.
Under the “Telemetry” tab, the first section requests a folder path for the DCP- configura-
tion files. This is the folder path where RaceCon stored the INI files required by WDServer.
Select the “Change” button next to this section and navigate to this folder. A template can
also be specified for the file nomenclature for logged telemetry as well as a save location.
– To insure proper communication between WDServer and the receiver, do not delete
any old INI files from this folder path. As mentioned previously, RaceCon will generate
a new INI file each time a project is synchronized or saved; each new INI file instance
has an incremented file name. Retaining all of these INI file iterations will insure that

Tools | 4
Bosch Motorsport Telemetry_System_LTE65_Manual 17/28
WDServer always has a reference to whichever configuration is programmed into your
vehicle’s logger system.
– If the RaceCon project for the vehicle resides on a different computer than that which
is used for telemetry, then all INI files for a given project should be transferred to the
telemetry computer after every data synchronization in RaceCon. WDServer may have
trouble recognizing INI files stored on removable media, so best practice is to copy
these files to the telemetry computer’s hard drive.
4.3.2 Adding car in WDServer
To set up a new car, select Add Car.
In the Car settings tab, enter a name for the new vehicle. This name will be used as part of
the file name for WDServer’s log of received telemetry data and will also show up in Darab
when searching for the telemetry stream in the Network folder.

4.4 WinDarab
WinDarab is the data analysis program for Bosch Motorsport devices, including streamed
telemetry from Bosch Motorsport loggers.
Extensive WinDarab Documentation is available on the Bosch Motorsport website.
4.4.1 Loading the Telemetry Data
The following is an example of file name and data format. File is typically located in Win-
Darab/WDServer which will automatically be in the computer tree portion of the file ex-
plorer when opening a file in WinDarab as shown below.
In the File Explorer, click ‘Open’ and navigate to the data set. Under ‘Network’, search for
the car or cars that are required for viewing.

5 Troubleshooting/FAQ
My transmitter and/or receiver will not connect to the cell network indicated by a flashing
green life LED and flashing red WAN LED,
– Indication of an antenna problem. Check for correct connectivity and placement of
transmitter antenna.
My devices are connected to the network, but my transmitter is not sending data indicated
by no flashing on the data LED.
– Check that the datalogger’s TX port is wired properly to LTE65’s RX port.
My devices are connected to the network and both my transmitter and receiver devices are
showing activity (“WAN” lights are flashing and not red during use), but I am unable to re-
ceive data in WDServer.
– Check that the LTE65 receiver’s TX port is wired properly to your laptop.
– Indication of a network issue on your PC. Please contact your dealer for assistance.
My telemetry file in WinDarab has no data but all lights on the LTE65s show data is being
sent and received.
– Check in WDServer if Block/Sec and Byte/Sec are received. If Byte/Set is greater than
0 and Block/Sec is 0 this is likely an INI file. Confirm the INI file in the directory refer-
enced by WDServer matches the directory the INI file from the latest configuration
sent to the logger device.
I have another issue or my problem is not solved.
– Note the telemetry_state mode in RaceCon or WinDarab and contact your Bosch
Motorsport contact.
