Works without trouble

These usb to serial converters are often finicky. This one just worked immediately. Nice.

Great for PTZ camera control and Simple to understand

Great tool! It is allowing me to have RS485 connectivity and control to a PTZ camera and coming off of another device that will control my camera without the manufacturer's utility. Simple to connect and does the job without any errors. I have been using this extensively without fail. I am a fan!!!

Worked and saved me money

I used this to connect to a vision scanner at work. The manufacture sold a cable that was around $300. So I figured I’d give this a shot. Very easy to connect and good instructions. Only quality issue I noticed was the circuit board is exposed. So, using this in the elements may be a problem. I personally keep this in my office and only bring it out when I need it.

Took a few minutes for all the drivers to settle down and work.

I got this particular maker since it was rated as being very compatible. And after waiting a few minutes for Windows 11 to correctly load up all the drivers for Com3 to appear; it does indeed work without fail. Nice clean signaling and now works without fail. Sure, I may make a mistake; but at least I don't have to worry about the communication.

Good Adapter For The Price

I used this product to interface with a Spectrum (Omneon) video server over VDCP/Louth (RS-422 full duplex) without issue. The unit was easy to setup (install drivers from the included CD, connect the cable), and the pin-out is straightforward. The top 5 pins (left-to-right) are Ground, RX-, RX+, Tx-, TX+. I would definitely buy another.

Does not receive in RS485

This device appears to only transmit using the RS485 protocol, not receive, by design. You cannot use it to receive transmitted RS485 from a controller to view the output from the controller on a PC screen. If I'm wrong, then my unit is defective.
