Great for plugging into rs485 type networks. Review: Works just fine - I bought this to connect to a CO2 controller I purchased so I could adjust the settings and read the CO2 levels with my computer. It totally worked exactly like it was supposed to. The db9 to terminal bus adapter is well labeled and I had no problem wiring it to the controller correctly. I don't know why these RS-485 to usb are so pricey, perhaps it's the FTDI chip. I don't know much about the FTDI chip, but from what I've read it is the most reliable for processing rs-485 to usb. I would recommend this to a friend, however if you can find a cheaper one with the FTDI chip, I would assume it is just as reliable. I liked this one because it came with the nice terminal bus.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great device, going strong 5+ years *by A***R on January 27, 2024* Great usb serial device, easy to use and has been trouble free for the past 5+ years I’ve had it. Great for plugging into rs485 type networks. ### ⭐⭐⭐⭐⭐ Works just fine *by P***E on February 24, 2013* I bought this to connect to a CO2 controller I purchased so I could adjust the settings and read the CO2 levels with my computer.

Thanks! ### ⭐⭐⭐⭐ Works as advertized *by K***M on March 2, 2013* I have been using this converter on two different Win 7, 64 bit machines and on a Mac Mini running 32 bit Win 7 in Boot camp. The device works flawlessly on all machines. The port assignment can be changed in Window's device manager and the assignment is retained by the OS. I am using the device in a RS-422 set up with only one receiver. The device arrived pinned as; 1=T+, 2=T-, 3=Rx+, 4=Rx-, 5=Gnd, and 6=Vcc. It has a supplied terminal block so, if needed, you can cut the end off of a serial cable and connect that to the terminal block as needed. I have two different devices with different pin outs, so I used some RJ45 to DB9 modular adapters, one for each device and one to connect to this RS-422 adapter. The connection can then be made with a RJ45 cable. You will probably need an Ohm Meter to figure out the pin assignments for the RJ45/DB9 adapters. I would have given 5 stars but the price seemed a little high for what it is. If you do need a USB to RS-422 adapter, this one works well. ## Frequently Bought Together - Gearmo Pro 5ft.
