Introduction
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. An API allows simple integration within a
specific application environment. The 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.
The PCAN-GPRS Link has ECE type approval (E1), which guarantees
its problem–free use in vehicles.

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 PCANGPRS Link is set in operation. The wake-up time is also 370 ms.
16
PCAN-GPRS Link – User Manual
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.

3.3.1
Cabling
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.
17
PCAN-GPRS Link – User Manual

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
High-Speed-CAN networks may have bit rates of up to 1 Mbit/s. The
maximum bus length depends primarily on the bit rate.
The following table shows the maximum possible CAN bus length
at different bit rate:
Bit rate
Bus length
1 Mbit/s
40 m

110 m
250 kbit/s
240 m
125 kbit/s
500 m
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.

Transfer 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.

Firmware-Upload
You can transfer the firmware on different ways to the microcontroller of the PCAN-GPRS Link.
via the SD card (this is the recommended method)
via firmware update over the air
via the serial interface
6.1
Uploading the Firmware via SD Card
From the supplied CD, subdirectory \Software and Firmware\
decompress the ZIP-Archive PCAN-GPRS_Link_
ExampleProject_Vx.x.x.zip to C:\ including all contained
subdirectories.
The directory C:\ PCAN-GPRS_Link_ExampleProject_Vx.x.x and
all subdirectories are created.
Transfer the following files to the SD card:
FirmCRC.BIN
crc.txt
update.ini
Note: Check the update.ini. Thus the update will be
performed, the following string must be included in the file:
UPDATE=TRUE.
Write everything in capital letters and put no characters before
the string. Otherwise, the string will not be recognized by the
boot loader.
34
PCAN-GPRS Link – User Manual
After inserting the SD card into the PCAN-GPRS Link the module
starts programming itself. Switch the module off and on again.
6.2
Firmware Update via GPRS
Using the internal boot loader, a firmware update via GPRS can be
done. To keep all update options open the GPRS interface is not
predefined by Peak-System. Transfer the files FirmCRC.bin,
crc.txt and update.ini on any path onto the module so that
you can use the update.
After the data is transmitted, the microcontroller writes the data to
the SD card. After a reset the module will start by itself.
6.3
Uploading Firmware via the Serial
Connections
This section shows how to initiate the microcontroller’s boot loader.
The actual upload process is done with the tool Flash Magic (on the
CD in the directory tools), which is supplied by a third party and is
not described here. You can get more details from our customer
support (see address on page 2).
Attention! If you transmit the firmware with this procedure, the
boot loader for the update via SD card will be overwritten
Do the following to initiate the microcontroller’s boot loader:
1.
Switch the PCAN-GPRS Link off by disconnecting it from the
power supply.
2.
Open the casing of the PCAN-GPRS Link by removing the
screws in order to gain access to the board.
35
PCAN-GPRS Link – User Manual
3.
Establish a connection on the J6 connector panel between
pin 4 (/Boot_ser) and pin 5 (GND).
Figure 8: Connection at connector J6
4.
Establish a serial connection to the computer via the serial
port of the microcontroller (attention: TTL levels).
5.
Switch the PCAN-GPRS Link on by applying a supply
voltage.
Due to the Low level on port P0.14 of the microcontroller,
the PCAN-GPRS Link starts the boot loader for serial
transfer.
