CAN232 is a very small
dongle that plugs into any PC COM Port, or any other RS232 port
in an embedded system and gives an instant CAN connectivity. This
means it can be treated by software as a standard COM Port (serial
RS232 port) which eliminates the need for any extra drivers. Sending
and receiving can be done in standard ASCII format.

The module plugs directly
into a standard serial port and provides a standard DB9 male output
to CAN systems according to CiA (CAN in Automation) recommendations.
It is powered with 8-15VDC through the CAN connector with ESD protection
and reveresed power. It consumes max 100mA, but normally not more
than 40mA (this depends on BUS load and eventual CAN cable errors
etc.). Use your own RS232 LIB/drivers (in e.g. Visual Basic, Deplhi,
according to CiA recommendations DS102-1.
The CAN232 is powered with +Vin (6-16VDC) at pin 9 and GND at pin

Sample programs in C,

products from LAWICEL
has same commands as CAN232, though some removed (such as Poll One
and Poll All) since it is a new product and we do not need to be
backward compatible. With CANUSB you will get increased bandwith
of CAN and can work at higher busloads. The goal was to make it
the choice of CAN to USB converters if you work with CAN speeds
up to 500Kbit/100% busload, 750Kbit 50% busload or 1Mbit 25% busload.
We feel the market need a low cost CANUSB device with same functionallity
and easyness as the CAN232. Price is €99 in single quantity.
CANUSB works on both Windows and Linux platforms.
Looking inside the CANUSB,
you find a dense 4-layer printed circuit boards with parts on both
sides of the PCB. The CANUSB will be firmware upgradable through
the USB interface, so customers easily can update firware when we
release a new improved software or new functions in the software.
CANUSB is also CE ceritified, which many other similar products
