| 441097 | 2006-03-27 03:37:00 | Can someone help on this one – well outside my area! How can I get an RS485 port on my PC?! Need it to try out a new security camera settings. Is it possible to get a DVR card with attached RS485 ports?! Many thanks |

With RS422 (as used on the Mac serial ports) it's just a matter of grounding the RX- line. RS485 is a bit more clever ... just a single pair. But 10Mhz at 4000 ft is pretty good speed/range. There are converters: Google (google.co.nz/search?hl=en&q=rs232+to+Rs485&meta=) will show some, (and give a design for one you can make yourself). |
