1Introduction
PCAN-GPRS Link is a hardware and firmware platform for the
recording and forwarding of vehicle data. There are two freely
programmable microcontrollers within the unit which process
internal vehicle data.
The PCAN-GPRS Link is provided as a development platform for
telematic applications.
PCAN-GPRS Link supports the evaluation of FMS and Bus FMS data
(Fleet Management Standard). This produces consumption-related
vehicle data. The DTCO info interface also allows the connection
and processing of a digital tacho with access to information such as
driver identification and driver working time. The GPS module can
be used to determine location and output the direction of travel.
There is an optional expansion to allow any volume of additional
data to be processed, output and recorded. These include
temperature and movement sensors, barcode scanners, RFID
readers, displays and WIFI or Bluetooth connections.

2.6 SD Card
The SD card is located in the card slot on the board of the PCAN-
GPRS Link. To format the SD card and/or to install the firmware, you
need an SD card reader and an SD card with maximum 2 GB
capacity (supplied with the PCAN-GPRS Link set is a 1 GB SD card)
Do the following to setup and/or install the SD card:
1. Unscrew the back panel of the PCAN-GPRS Link.
2. Press the SD card at its end to eject it from the card slot.
3. Insert the card into the card reader on the computer.
4. Format the card and/or copy the firmware onto it (see also
on page 34 Uploading the Firmware via SD Card
).
Format the SD card with the file system FAT16 or FAT32
through the appropriate application of the operating system
(maximum sector size 512 byte).
5. Log off the SD card from the Computer and take the card
from the card reader.
6. Insert the SD card back into the card slot.
7. Close the back panel of the PCAN-GPRS Link.

3Operation
The power supply of the PCAN-GPRS Link is switched on by apply-
ing the supply voltage. To save power it is possible to switch off the
internal power supply. Restart is only possible via CAN or clamp 15
(ignition). The RTC from the microcontroller and the GPS are still
supplied. This allows a fast GPS Fix.
Attention! The GSM antenna must always be connected! If this
is not the case, the transmitter can be damaged.

3.2 Wake-up
If the PCAN-GPRS Link is in Sleep mode, the operation will be
resumed by a wake-up signal.
Following possibilities are available for activating the PCAN-GPRS
Link by a wake-up signal:
CAN: When a message is received via CAN 1 or CAN 2, the
PCAN-GPRS Link turns on. Within the wake-up time of 370 ms
further incoming CAN messages are not processed.
Clamp 15 (ignition): With a positive level on clamp 15 the PCAN-
GPRS Link is set in operation. The wake-up time is also 370 ms.

PCAN-GPRS Link – User Manual
17
Figure 5: Power supply PCAN-GPRS Link
The PCAN-GPRS Link goes to sleep mode, if no CAN data is
transmitted/received, the microcontroller is inactive, and clamp 15 is
low. Activation of the PCAN-GPRS Link is in this case only possible
via CAN or clamp 15.
3.3 Cabling
3.3.1 Termination
A High-speed CAN bus (ISO 11898-2) must be terminated on both
ends with 120 Ohms. Otherwise, there are interfering signal
reflections and the transceivers of the connected CAN nodes (CAN
interface, control device) will not work.
The PCAN-GPRS Link does not have an internal termination. Use
the adapter on a terminated CAN bus.

PCAN-GPRS Link – User Manual
18
3.3.2 Example of a Connection
Figure 6: Simple CAN connection
In this example, the PCAN-GPRS Link is connected with a control
unit by a cable that is terminated at both ends.
3.3.3 Maximum Bus Length
CAN networks may have bit rates of up to 1 Mbit/s, where all CAN
nodes must be able to process messages simultaneously. The
maximum bus length depends on the bit rate.
The following table shows some examples with the bus length in
relation to the bit rate:
Bit rate Max. bus length
125 kbit/s 530 m (580 yards)
250 kbit/s 270 m (300 yards)
500 kbit/s 130 m (140 yards)
1 Mbit/s 40 m (45 yards)
Note: The PCAN-GPRS Link is set by default to 500 kbit/s. Only
in the case of the use of FMS used standard is 250 kbit/s. All
other bit rates can be used freely.

4Transfer CAN Data via
TCP/IP
The PCAN-Link software package allows the transfer of CAN data
using TCP/IP. PCAN-Link is based on the CANAPI2 interface by
PEAK-System, thus supporting various communication scenarios
(PCAN-Link is not included in the scope of supply).
Several virtual or physical CAN networks can be connected via a
network medium.
A simple PCAN-Link client can be integrated in the PCAN-GPRS
Link. Note that the data rates of GPRS are 50 kbit/s in the best case.

5Firmware
The WinARM software provided can be used to produce your own
firmware. This chapter describes the installation of the package.
Furthermore, the properties for the programming of CPUs are
described.
Note: You need the WinARM package only if you don’t have the
full version of the μVision development environment!
The ARM Evaluation Software μVision from Keil to compile the
firmware can be found at:
https://www.keil.com/arm/demo/eval/arm.htm
Attention! From μVision version 4.20, there is currently no gcc
support. Use the version 4.13 or less.
5.1 Installing the WinARM Package
This chapter covers the installation of the program package
WinARM. Software, source code, and additional information is
included on the supplied CD in the following directory branch:
/tools
WinARM is collection of tools to develop applications for ARM
processors and microcontrollers on Windows platforms. The
package includes the GNU GCC Compiler for C and C++.
The installation of the WinARM package is done in two major steps,
the decompression of the ZIP archive and the setup of additional
search paths under Windows.
