Hi,
For a reason I cannot explain the new unit has started to connect :-)
using the FTDI adaptor, with RX & TX inverted, see snap attached
output level is 5v active high at the PCAN-LIN RX line

The existing units with a configuration already inside will not connect.
I'll try again with a 12v data signal and let you know how I get on

Thanks
Steve

Hello, again..

5v signal from adaptor TX line converted to 12v
snap one shows 12v level pulses on the line when PCAN-LIN unit NOT connected
snap two shows this signal being reduced (clamped internally) when PCAN-LIN unit IS connected.

So at the moment, i can connect to new unit but not units previously used i.e. have a .pclin configuration installed and units running, indicated by blinking LED's

Any ideas as to how to access these units greatly appreciated.
Thank you
Steve

Hi,

a RS232 interface uses positive and negative voltages. So please use an USB2Serial module, as linked in my previous post. This will work out of the box.

BTW: we also offer a USB-RS232 Adapter (FDTI Chip Version), ordering number: IPFH-000101, price 18.-Euro (not available in the webshop, but can be ordered by email)

regards

Michael

Hi Michael
We are now able to reliably connect to a new unit and a 'previously used' unit.
I'm accepting that one unit I have done a lot of testing with now seems to be faulty.
I'm happy to now call this issue 'closed'.
Thank you for your assistance and patience.
We got there eventually :)
Best wishes
Steve
