RS485 connecting issues
RS485 connecting issues
(OP)
I have several Vaisala Temp/humidity sensors (HMP110) with RS485 outputs (2 wire half duplex). The input power is 5-28VDC max 5mA. I want to connect it to the National Instruments PXIe 8431/16 which has 8DB9 RS485 male connectors. The Vaisala instrument has 4 colored wires and 1 ground. I would like to know the best possible setup for connecting these sensor to the PXIexpress. What components will I need?

If it's just for a one off, you can solder wires to a DB9 solder bucket plug, wrap some tape around it and you're good to go. If you need something more permanent it might be worth buying some DB9 flying leads, wire it to a terminal strip and put that in a junction box.
