Works with Garmin 19x HVS on long cable at 38400
Mary Sue Hayward✓ Verified Purchase•September 3, 2023
It works! It took me awhile to figure it out, but once there it was more of less obvious. It helps to look at the FTDI reference design for the 422 converter, and as remarked (and in one line of the user manual), 120 ohm termination resistors are recommended at the end of long high speed cables. In my case, needing to connect to a Garmin 19x at the end of 30 meters of cable, they weren't needed. The 'trick' that took me forever was that I initially connected the Garmin TX to the DTech TX lines -- didn't work. Swapped the polarity and lo and behold I could see data. But I then couldn't send messages to the Garmin. After some down time thinking, I correctly connected the Garmin TX to the DTech RX and the Garmin RX to the DTech TX and it all worked. I did have to swap polarity too, but now everything works great!
Will connect a NABU PC (1984 Ottawa Canada) to the Nabu Network (2023)

Excellent quality that was easy to install and connect to a DIN cable to the NABU PC.
Handy little adapter

This worked great for my needs, I used it on Win10 for a while to control several Oriental Motor drives via MODBUS in a multi-point configuration. In the final installation I switched to a DTECH RS-232 to RS-485 adapter since the control interface only had an RS-232 port. I now use the USB adapter on a Huanyang VFD running RS-485 which works fine as well.
I didn't like how the activity lights blurred between the little status light windows so I popped it open and glued some black tubing over each LED to keep them constrained to their own status light window which really improved visibility of the Tx/Rx lights.

I use this product with Growatt inverter. Easy use
Works nicely under Linux

Installed without any drivers needed under Ubuntu. Works nicely. (As I'm using a pre-installed version of the OS, it's possible drivers had been added separately).
