1. OVERVIEW
Dear customer,
Thank you for choosing our product.
In the following we will show you what has to be considered
during commissioning and use.
Should you encounter any unexpected problems, please feel free
to contact us.

1. DETAILS
The CAN board is compatible with Raspberry Pis (and other ARM single
board computers) on a voltage level of 3.3V, as well as with Arduinos on a
voltage level of 5V. A general pin assignment can be found in the following
diagram and table. A detailed connection overview and instructions for use
in combination with the dierent systems can be found in the following
chapters.

1. DETAILS
For best operation between CAN High and CAN Low, a terminal resistor
is required.
A 120Ω resistor at each bus end is optimal for a maximum range over
longer distances. This is already integrated in our module and can be
activated or deactivated at connection P1.

2. USAGE WITH AN ARDUINO

For use with an Arduino, we recommend using the MCP2515 library.
This is available on the Github platform and can be downloaded there.
Simply copy the library folder into your Arduino library.
This is usually located at :
"C:\[your username]\Documents\Arduino\libraries".
If you are using an Arduino Mega, please note that the SPI interface is
connected to dierent pins than the Arduino UNO.

2. USAGE WITH AN ARDUINO
Among the examples of this library you can find an example for a
transmitter as well as for a receiver. With these examples the basic
functionality of the system can be explored excellently. With a second
Arduino and a second Can module, for example, a communication
between both devices can be established, where one module takes over
the transmitter and the other module the receiver. In this case, connect
both CAN-High interfaces and both CAN-Low interfaces of the two
modules with each other.

3. USAGE WITH A RASPBERRY PI

INT 22 (GPIO 25)
SCK 23 (SCK)

VCC1 2 (5V)
VCC 1 (3.3V)
Attention! Please make sure to connect the VCC1 and VCC connectors
correctly. The module works with a voltage level of 5V, but in contrast to an
Arduino, the inputs and outputs of the Raspberry Pis are only designed for a
voltage of 3.3V. For this reason, our module has two voltage inputs (VCC1
and VCC). This allows you to use the module on your Raspberry Pi without
hesitation and without permanently damaging it.

3. VERWENDUNG MIT EINEM RASPBERRY PI
To install the necessary extensions and to be able to use the CAN module
with a Raspberry Pi, please update the package list and install the extensions
can-ultis:
Next, use the following command to get the kernel version of your Raspberry
Pis. This is necessary for the further configuration of the system.
You will be shown the current kernel version (e.g. "4.4.41-v7").
Next, open and edit the config.txt file with the following command:
If your kernel version is 4.4.x or newer, please add the following lines to the
end of the file:
However, if your Raspberry Pi runs with an older kernel version, please add
the following lines to the end of the file instead:
The 8000000 stands that the MCP2515 operates with a clock of 8 MHz. This
depends on the quartz used and may need to be adjusted.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install can-uls

3. VERWENDUNG MIT EINEM RASPBERRY PI
Save the file with the key combination CTRL+O, confirm the saving process
with Enter, and exit the editor with the combination CTRL+X.
Restart your Raspberry Pi with the following command:
Aer the restart has been completed, you can now start the CAN interface:
The system should now be ready. You can now start a first send attempt with
the following command:
Instead of attempting to send, you can also start receiving:
For example, in order to gain initial experience with the module, two
Raspberry Pis and two CAN modules can be used to initiate communication
between the two devices.
In this case, make sure that you also connect the CAN high pins of both
modules as well as both CAN low pins.

Symbol on electrical and electronic equipment
This crossed-out dustbin means that electrical and electronic appliances do
not belong in the household waste. You must return the old appliances to a
collection point. Before handing over waste batteries and accumulators that
are not enclosed by waste equipment must be separated from it.
Return options
As an end user, you can return your old appliance (which essentially fulfils the
same function as the new appliance purchased from us) free of charge for dis-
posal when you purchase a new appliance. Small appliances with no external
dimensions greater than 25 cm can be disposed of in normal household quan-
tities independently of the purchase of a new appliance.
Possibility of return at our company location during opening hours
Simac GmbH, Pascalstr. 8, D-47506 Neukirchen-Vluyn
Possibility of return near you
We will send you a parcel stamp with which you can return the device to us
free of charge. Please contact us by e-mail at [e-mail] or by telepho-
ne.
Information on packaging
If you do not have suitable packaging material or do not wish to use your own,
please contact us and we will send you suitable packaging.
