LAWICEL sets another
record in speed and performance with the new CAN232, built on same
base technology and know-how as the original version. The new CAN232
comes with more memory, 4 times faster microcontroller, new commands
and possibilities for the customer to update the firmware for free
in less than 5 seconds without opening the case.
Initial tests at customers
and at LAWICEL shows that the troughput has more than doubled compared
to the original version of CAN232. We have now tested it by shooting
500 frames per second with standard 11bit ID's and 8 databytes using
115,200baud RS232 and no single frame is lost during a whole day.
Another test was done shooting 1000 frames per second with standard
11bit ID's and 2 databytes and same result, not a single lost frame.
In the initial release
of the new CAN232, we have increased the receive FIFO from 8 to
32 messages, added time stamp on the messages in milliseconds (option
to be backwards compatible with original version) and optimized
the CAN core functions for speed and memory usage. Further more
we have added the "Auto Poll" function, which can be set
with a command so incomming CAN frames are sent directly out on
the RS232 without the need of polling them manually. Finally we
added a bootloader in the new CAN232 which makes it possible for
the customer to update the firmware inside the CAN232 to new versions/features
that we develop (the original version had to be sent to us for update).
This bootloader also makes it possible for either the customer to
make their own software for the CAN232 or that LAWICEL can do customizations
and add more functionallities without sending the hardware arround
Excisting users with
the original CAN232 cannot benefit of these new features, however
LAWICEL can upgrade the hardware in their original CAN232. Contact
LAWICEL or your local dealer for more information about this.
The new CAN232 is now
availible. We will update this site in the next weeks with more
information, updated demo programs and manuals, so check back often
during the next weeks.
