1 Introduction
The PCAN-RS-232 is a programmable module for the communication between
RS-232 and CAN. The conversion of data traffic is done via a NXP LPC21 series
microcontroller.
The behavior of the PCAN-RS-232 can be programmed freely for specific applications.
The firmware is created using the included development package with GNU compiler
for C and C++ and is then transferred to the module via CAN. Various programming
examples facilitate the implementation of own solutions.
On delivery, the PCAN-RS-232 is provided with a demo firmware that routes from
CAN to RS-232 and vice versa. It allows to configure the data transfer as well as the
hardware with serial control commands. The corresponding source code is included
as an example in the scope of supply.

For direct access to the debugging ports (JTAG) of the microcontroller, an additional
– yet not equipped – connector panel is available on the circuit board of the
converter.
Furthermore the board has four coding solder jumpers in order to assign a fixed
status to the corresponding input bits of the microcontroller. A concrete application
is to identify a PCAN-RS-232 converter on the CAN bus for a firmware upload,
especially if there are several converters connected and in operation.
The following subsections describe each connector assignment.

2.2 J5 Connector Panel: JTAG Ports
The unpopulated connector panel J5 on the PCAN-RS-232 converter’s circuit board
provides an access option to the JTAG ports of the LPC2194/01 microcontroller (μC)
for hardware debugging.
Gain access to the unpopulated J5 connector panel:
Risk of short circuit! Soldering on the PCAN-RS-232 may only be
performed by qualified electrical engineering personnel.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
1. Disconnect the PCAN-RS-232 from the power supply.
2. Unscrew the two screws.
3. Remove the housing cover.
4. Remove the circuit board.
