I need to configure a sensor (Thies 3D Sonic Anemometer, Manual: https://www.biral.com/wp-content/uploads/2015/01/4.383x.xx_.xxxUS3D.pdf) via my computer, it has RS485 full duplex and half-duplex capability.
From the wiring diagram I found that there are four pins available: TX+ (pin 5), TX- (pin 2), RX+ (pin 4), RX- (pin 1) for full duplex. For half-duplex pin 2 serves for TX-/RX- and pin 5 as TX+/RX+. Now I only have an RS485 Adapter, which has four ports labelled as A, B, Ground and +5V.
As far as I know, the sensor has last been operated in full duplex mode. Will I damage anything, if I hook pins 2 and 5 to my adapter (YF USB to RS485 adapter: https://www.play-zone.ch/de/yf-usb-zu-rs485-adapter.html)?
How do I know which pin to A and which to B on the adapter side?
