1 Introduction
The PCAN-RouterDR has two High-speed CAN channels. Their bit rate is adjusted
with a rotary switch on the device front. The module forwards the message traffic
bi-directionally 1:1 between both connected CAN busses.
The ports of the PCAN-RouterDR are isolated against each other and against the
power supply with at least 500 V. Furthermore, CAN 1 has a separation voltage of up
to 5 kV conforming with IEC 60601-1. With its DIN rail casing and the support of the
extended temperature range, the module is suitable for use in an industrial
environment.
Just like the PCAN-Router in the aluminum casing, the PCAN-RouterDR can be freely
programmed. A corresponding development package is included in the scope of
supply.

3 Hardware Configuration
3.1 Configure Bit Rate
Using the rotary switch of the PCAN-RouterDR, the CAN bit rate can be adjusted. The
selected bit rate applies to both CAN channels. At delivery, the switch is set to C
(500kbit/s). A changed setting takes effect after the reset of the PCAN-RouterDR.
Performing a reset is described in section 4.2 Restart.

3.2 Activate CAN Bootloader
With rotary switch position F the CAN bootloader is activated after a reset. This
allows you to transfer a self-created firmware to the PCAN-RouterDR via CAN. The
upload procedure is described in detail in chapter 6 Firmware Upload.
Rotary switch position F for activation of the CAN bootloader
When the CAN bootloader is activated, the LEDs indicate the following states:

Status off
CAN 1 orange blinking
CAN 2 orange on

3.3 Internal Termination
The termination for each CAN channel can be separately activated with switches on
the board. At delivery, the termination is switched off. A High-speed CAN bus
(ISO11898-2) must be terminated on both cable ends with 120 Ω. Otherwise,
malfunctions may arise.
We recommend to do termination at the CAN cabling, for example with
the terminating resistors PCAN-Term (IPEK-003002) or PCAN-MiniTerm
(IPEK-003002-Mini). Thus, CAN nodes can be flexibly connected to the
bus.
Activate internal termination:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.

4 Operation
The PCAN-RouterDR is activated by applying the supply voltage to the respective
connectors. More information about the connections can be found in chapter 2
Connections and Operating Elements. The firmware in the flash memory is
subsequently run.
On delivery, the PCAN-RouterDR is supplied with an standard firmware which
forwards CAN messages 1:1 between the two channels. The bit rate selected at the
rotary switch is used. An incoming CAN message causes a change between green and
orange of the LED status indication for the respective CAN channel.
Information on firmware can be found in chapter 15 Creating Own Firmware.
4.1 First Steps
1. Mount the PCAN-RouterDR at the appropriate position on the DIN rail by
hanging it in at the top of the rail and snapping it to the bottom.
2. Connect each of the two CAN ports with the corresponding CAN network.
3. If the bit rate is different from the default 500 kbit/s, set the bit rate with the
rotary switch (see section 3.1 Configure Bit Rate).
The new bit rate takes effect after reset (see section 4.2 Restart).
4. Connect the PCAN-RouterDR to a power supply (8 to 30 V DC).
The PCAN-RouterDR now forwards the CAN messages one on one.

4.3 Signal Delay
The signal delay at forwarding of a CAN message consists of a fixed processing time
of the microcontroller of about 30 μs and a variable delay depending on message
length and bit rate.
For example, the signal delay of a CAN message with an 11-bit ID and eight data
bytes at 500 kbit/s is approximately 260 μs.
4.4 Status LEDs
A standard firmware is pre-installed on delivery. Therefore, the LEDs CAN 1 and CAN 2
light up between green and red on incoming and outgoing CAN messages.
The LEDs can indicate the following states:
LED Status Meaning
Status
Off No CAN communication
Green blinking Operational
Red flashing Reset
CAN 1/CAN 2
Green blinking Data is transmitted
Red flashing Communication error (error frames)
Power Green on Power supply is present
Additionally, they light up orange when the bootloader is activated. Additional LED
functions can be programmed with your own firmware. More details can be found in
the programming examples supplied.
