I am trying to use a Raspberry Pi 4 to communicate to a temperature controller made by Lakeshore (model 240-8P).
The manual gives me the following information:
Digital I/O – USB
Function: Emulates a standard RS-232 serial port
Baud rate: 115,200, 8 data bits, 1 stop bit, no parity, no handshaking
Connector: USB micro-B
If I connect it to one of the four standard USB ports, it shows up with I use the lsusb command in the terminal. It does not create a /dev/ttyUSB file and I can't figure out how to echo commands to the device.
Do I need to be using a CP2102 converter attached to the pins rather than use the built-in USB ports? Do they behave the same?
Do I need the raspberry pi to create the /dev/ttyUSB file before I can use it?
Do I need to load a special driver?
Thank you!
