A PCAN-LIN module not be confirmed

Post by Redin_NA » Tue 8. Sep 2020, 16:12

I faced with issue when I connect to PCAN-LIN by USB to serial port converter. On PCAN-LIN apply voltage. Module blinking. By PCAN-LIN CT I connect to PCAN-LIN and get error

With what it can be connected?

From this topic it becomes clear that. RS-232 need 12V Levels. Is it a prerequisite for a correct connection?

Hello,

yes you need a real RS232 COM port to connect to the PCAN-LIN. When using an USB2Serial device, please use one with FTDI chipset.

Sorry, but not everything is clear.
All FTDI chipsets have this electrical characteristics

The FTDI device can only accept 12V signal from PCAN-LIN, or more (Receiver input voltage range +-25V), but the output signal "Transmitter output voltage swing" = +-5V.
is this a sufficient level for the PCAN-LIN module?

Hi

a standard COM port has +/-12V signals. So if you use a FTDI chip with ttl output, you have to add a MAX232 level shifter to get the +/-12V signals for the COM port. We also offer ready to use FTDI based RS232 USB2Serial devices, ordering number IPFH-000101, USB-RS232 Adapter (FDTI Chip Version), price 18.-Euro net.

Hi,

you can order this USB2Serial adapter by email, we don't have it listed in our webshop. We can support you with our CAN and LIN adapters, but not for 3rd party tools like FTDI chips. Please contact FTDI for support about their products.

regards

Michael
