Using it for RS422 TXA- (1)TXB+ (2) / RXA- (6) RXB+ (7)?** A: I don't know. I used this device in a development project for a client. I used it with Cygwin on a Windows 7 system and on a RS485 bus to which I had attached multiple devices. It worked flawlessly in this respect. No clue about RS422 or later Windows releases. **Q: I need for a 2 wire PTZ security camera, what will work that has a usb connection? This is driving me crazy. PLEASE HELP** A: This unit is ONLY for USB to RS-485 connection, however, it will handle a 2 wire connection. I'm not sure what drivers a PTZ camera needs, but you should be able to find them on their website. **Q: Can I use 2 of these converters on one Windows 7 computer (using two separate USB ports) to do a loop back test?** A: I haven't done it myself, but it should work fine. I have one of these. Once installed, the device appears to Windows 7 as a serial port device. If you install two of them, they will appear as two separate serial ports.You just need to make sure to wire them up appropriately. ## Frequently Bought Together - Gearmo Pro 5ft.
