Review: Perfect if you're setting up ICS panels - So say you have a bunch of industrial control and alarm panels that absolutely need an RS-422/482 serial interface to allow you to program them. Say the original vendor wants to set up a contract for many MANY monies to come out and do that for you. As I've said before - nu-uh. You spin up one of these babies, slap it into a laptop, add a couple of connectors, and as they say Bob's your uncle! Worked great. Came with software I never bothered to install. Got the job done. Sittin' there waiting for another ICS to program...
Review: Great converter. - This works great for what I needed it for (programming LED text signs).

## Questions & Answers

**Q: I lost my software CD.  Is there anywhere the software can be downloaded?**
A: The USB serial adapter use the FTDI chip, you can download a driver from FTDI website (Steps: http://www.ftdichip.com>“Driver”>”VCP Drivers”> choosing a corresponding system driver on the opened page). If you can't download it, please contact us by clicking "contact seller" of the order, we will send you a instruction file.

**Q: Will this work with 4 wire RS485 connections?**
A: So far I use it for two wire, but if I recall correctly, when I got my first one (I've done repeat purchases) I did test it with a four wire setup initially.  I think the instructions did show the setup, but you'll have to check to be sure.

**Q: Will this do 232 connection?**
A: No, It won't. The USB to RS485 adapter you asked is for RS-485 or RS-422 connection. 

For RS232 connection, you may check DTECH RS232 serial cables below:

10ft USB to RS232 cable (FTDI chip) ----  http://www.amazon.com/dp/B017D51ZRQ
Thank you very much!

**Q: Will this work with valence lithium ion battereis?**
A: I'm not clear what you are asking.  This device is powered by the USB port on the computer that it is plugged into.  No batteries required.

Can you tell me more about where the lithium ion battery is located in your situation?  Are you trying to power this with a battery, rather than the computer's port?

### ⭐⭐⭐⭐⭐ Great converter.
*by J***. on July 27, 2025*

This works great for what I needed it for (programming LED text signs).

### ⭐⭐⭐⭐⭐ Work perfectly right of the box
*by D***E on June 14, 2024*

I needed to replace my old RS485 to USB controller and my software vendor suggested this model. It work perfectly right out of the box. It comes with a driver CD but I did not need it. Also included is a breakout box to adapt between the 9 pin type D serial connector and the RS485 twisted pair cable. I did not need to use the wiring block as my RS485 cable was already terminated into a female 9 pin connector that mated perfectly with this RS485 adapter. Literally a plug and play solution for me. Love it!
