5 Frequently Asked Questions
(FAQ)
Question
Why doesn't PCAN-USB
have an integrated
interface for USB 2.0?
The data transfer always
stops after a short period
of time, when a CAN
application has been
started (status LED
shines continuously
instead of blinking).
Does PCAN-USB also
work with DOS?
Answer
The transfer rates defined by the USB
1.1 standard are sufficient for handling
the upcoming data from the CAN
traffic and additional management
information. USB 1.1 devices also work
on USB 2.0 interfaces.
It may be that you use an older PCAN-
USB adapter being connected to a PC
with USB 2.0 interface. PEAK-System
has a solution for this problem. Please
contact us on this matter.
No. DOS does not support the USB
standard, and on the other hand PEAK-
System doesn't provide a special
driver. In order to have a CAN
connection with DOS you may
alternatively use the PCAN-Dongle for
connection to the parallel interface, for
example.
