6.4 Uploading Firmware via the Serial
Connections
This section shows how to activate the microcontroller’s boot-
loader. The actual upload process depends on the upload software
used which is supplied by a third party and is not described here.
Important note:
When uploading a firmware via the RS-232
interface, the CAN bootloader may be overwritten. Afterwards,
a firmware upload via CAN is not possible anymore.
Do the following to activate the microcontroller's bootloader:
Danger of short circuit! Take great care when soldering to
avoid short circuits.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
1. Switch the PCAN-Router off by disconnecting it from the
power supply.
2. Open the casing of the PCAN-Router by removing the
screws in order to gain access to the board.
3. Establish a connection on the J4 connector panel between
pin 4 (\Boot_ser) and pin 5 (GND).
4. Establish a serial connection to the computer or program
adapter.
This is carried out either via the RS-232 interface (IPEH-
002210-P only) or via the serial ports of the microcontroller
(TTL levels).
