Details
GM-482422 USB to RS-422 / RS-485 Converter FTDI Chip with Terminals photoelectric isolation interface converter can convert the single ended USB signal into difference RS-422 or RS-485 signal. The built-in photoelectric isolator of the USB to RS485 / RS422 Converter can provide an isolation voltage as high as 2500Vrms. There is also a rapid transient voltage suppression protector for protection of RS422 / RS485 interface with advanced TVS (Transient Voltage Suppressor) technology
Under normal conditions the TVS tube is in a state oh high resistance. However, when both ends of the TVS tube are hit by transient high energy, the impedance at the both ends can be depressed by the TVS at very high speed. After absorbing a high current, the voltage between the two ends is depressed and kept at a pre-set value; therefore no damage is caused to the electrical components behind the transient high voltage impact.
The protector can effectively restrain lighting or ESD (Electro-Static Discharge) with a protection voltage of 600w on each line for lightning surge and transient voltage events, while transmission of RS-422 / RS-485 is maintained by capacitors between the poles.

- Works great

My PC configured it automatically and it has been working with no issues!
Quality Value Price - Worked with M1 Mac
-
I was nervous because the driver listed only intel Macs. It worked for me with my M1 MacBook Pro running MacOS Ventura, version13.1, using cool term. The device showed up in cool term without installing any drivers. I initially had my baud set incorrectly. So, I thought it wasn't working and installed the driver. Now two devices show up in cool term. Both seem to work correctly.
Quality Value Price - perfect.
-
This does exactly what its supposed to and has held up to some extreme conditions (-36F to 111F) without fail.
Quality Value Price - Nice usb device for bacnet access.
-
This device plus YABE are good for looking at bacnet devices. Finding out what points are available and writting to some for settings.
Quality Value Price - Works perfect for Watlow EZ-Zone Controllers/Configurator
-
Bought this specifically to use for configuring a Watlow PM8 control using the Watlow EZ Configuration software (via RS-485) on a Windows 10 PC. Installed this adapter into USB port, let Windows search and install a driver and it was ready to roll. It came with a mini-cd containing a bunch of driver files and pdf manuals as well. Didn’t need the driver files, but the manual was nice, as it illustrates the adapter pin-out. Overall, a great purchase.
Quality Value Price - Great

Price abit high
Quality Value Price - Works for WATLOW PM6 Controllers
-
For the 1 person alive who is also using WATLOW's EZ-Zone Configurator, this works as well as - or better than - the one sold by WATLOW and is only about 14% the cost. We'll see how it holds up over time. Plugging it in and letting Windows (don't know about Mac & Linux) download the driver, or going to Device Manager and getting the driver off the web should get you running. Just remember to set the latency for the COM port if there are issues. You will still need to send power to the WATLOW device while trying to configure it.
Quality Value Price - Great for BACNET MSTP work.
-
I use this to find BACNET MSTP devices using BQT software. Helps to verify the instance numbers and change the Object Name too. Has big screws to connect transmit and receive, along with a light that shows the its transmitting and receiving.
Quality Value Price - Good RS485 adapter for pc.
-
Very simple except no wiring diagram. Just Google it - no problem. Works great.
