I have a Quatech ESU2-400 that I intend to use with some serial port development work. It has capabilities to send out data using RS-232, RS-422, or RS-485 ports. How would I configure a port on the device to send data out as a RS-422 port?
Hello and welcome here.
Any answer might depend on the version of openSUSE you use. Please always tell your openSUSE version.
Just a guess from me since I’ve never played with such a device. Hopefully, others with more knowledge about these devices can chime in here. I note that this device is supported by the quatech2 driver. I wonder if the driver sets up a number of serial port interfaces - some nodes representing RS-232, some RS-422 etc. You might need to examine dmesg output and perhaps observe output from
setserial -g /dev/ttyS*
Or perhaps it sets up multiple /dev/ttyUSB* nodes? Just a thought.
Reading the PDF data sheet available from here, I note that they mention Linux support is coming soon, which might be a limiting factor for configuration. Assuming that basic driver support does actually exist, it might just be a case of configuring the device via a Windows environment first.
