Start two instances with one PEAKUSB Dongle

Hello everyone,
I'd like to know wether it's possible to use at least one PEAK USB CAN Dongle (1-Channel) for accessing the CAN-Bus with two instances (two different applications).
I saw something similar at another competitor, and I need this function in my setup.
Please let me know, how to procees.

Hello,
This is possible with our Software such as PCAN-View or PCAN-Explorer 6, you can hook up multiple applications to the same hardware channel. Note: You cannot change the bitrate of a already initialized channel, so additional connections will use the same bitrate.
PCAN-Developer 4 supports this feature as well,in case you need to implement your own software.
More information can be found on the product page for the PCAN-Developer package:

Note: The PCANBasic API does not support this.
For further questions feel free to contact us again.
Best Regards
Marvin

Dear Marvin,
thanks for your fast reply.
I want to create two customized applications which shall use an existing CAN-Bus connection (same Baudrate etc. using NetConfig).
So this setup is only possible by using PCAN-Developer 4?
There are no other possibilites (e.g. each Computer which uses these two application also have a PCAN Explorer 5 installed)

Julian

Hello Julian,
Even though you can connect our PCAN-Software to a hardware-channel that was initialized with PCANBasic, it will not work the other way around.
Also PCANBasic applications cannot use connections used by another PCANBasic application.
Another possibility perhaps:
If the complexity of the application does not exceed the scope of what can be done with VBS-macros in PCAN-Explorer 5 then you could potentially use PE5 for your application.
Bear in mind that VBS is a scripting language and will run alot slower than a application written with a real (compiled) language behind it.
If your application relies on functionality which is not provided by VBS-macros and you have to access the same hardware channel twice by two seperate applications then yes, PCAN-Developer 4 is the right solution.
Best Regards
