Waveshare USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection

Q: Do you need a driver for this?

Hi,Yes, you can get the Driver installation from our wiki link: https://www.waveshare.com/wiki/USB_TO_RS485

Q: Connecting to a conductivity system (analog eval-cn0359-eb1z) power led comes on, yet neither transceiver led. are drivers needed? can i test system?

Hi,please check this way: 1) Disconnect the connection with analog eval-cn0359-eb1z first, send data to the host computer, and check whether TXD is on. 2) Try to test another USB port . 3) Change to another host computer and check whether the TX or RX lights are normal.

Q: I need this to control the “iot relay”, but since the usb ports are always powered, how can i control the on/off effect with this usb adapter?

This is a RS485 serial port adapter, the serial port is always on. If you have a RS485 relay module, the module will alway be on to, that module will control a relay, that it turns on and off by command over the RS485 serial connection.

Q: Will this work with the usb 2.0 on an rpi 3b? currently, when i hook plug it in, the os finds the adapter but then crashes the rs485 bus.

Hi,it can work with the usb 2.0 on an rpi 3b. If it is crushed ,it can be caused by low electricity
