Hello, If you only want to capture data from your RS485 port, communicate through Datasockets.
or you can use a RS-485 to RS-232 converter and Address to a RS232 port, such as COM1, then you use VISA to communicate via RS232 using ASRL1::INSTR. National Instruments sells RS485 board that that plugs into a PCI slot: http://sine.ni.com/apps/we/nioc.vp?cid=1363&lang=US I hope this helps. Regards~ Mathews
