## Questions & Answers

**Q: Are there any instructions on how to use it? Send or receive Messages?**
A: This is a "well behaved" product which seems to meet its specifications.  I recommend this product for what it does.  It works well for both send and receive.  I have several of them.

Serial communications can be a bit "tricky" so if you are not familiar with it, I recommend either a book or research on the internet.  A full discussion of this subject is a bit beyond this forum.  Good luck.

**Q: Would it work with rs422?**
A: Currently, only RS485 is supported.

**Q: this item include the cables on the picture?**
A: I don't know what picture you are looking at but - probably.  The package included a 4 conductor cable approximately 12 inches long.  It is designed to plug into the "TTL" end.

**Q: Does the tx go into high-z (tri-state) when not transmitting, so it can be used on modbus or multi-drop lines?**
A: Yes.  It works well with Modbus multi-drop lines as long as your "master" is working according to spec.  For the price, just try it to be sure it works for you.

## Customer Reviews

### ⭐⭐⭐⭐⭐ these are the nuts
*by C***S on 24 April 2023*

using them for all sorts of projects, i.e. communicating between 2x arduinos or 2x teensys. Great bit of kit.

### ⭐⭐⭐⭐⭐ this solved my RS485 connection problem
*by W***B on 13 August 2020*

I tried several ways to get an RS485 anemometer to work with an ESP32 mcu. This adapter finally solved my problem. Once I had it hooked up, it worked.Plus very fast delivery.
