Review: Works as USB to UART adapter, doesn't for LG - Using it to program a Dragino RS485-LN LoRaWAN endpoint and it works perfectly. This is a standard UART-spec compliant device. Note that LGs aren't.
Review: Doesn't work with LG TV. RXD and TXD are reversed. - Same problem reported as another review. Title should not say it works with LG TV, which requires crossover RXD (Tip), TXD (Ring), GND (Sleeve). Haven't found any direct adapters, just 3.5 to DB9, no USB, then use a crossover DB9 adapter.

### ⭐⭐⭐⭐⭐ Works as USB to UART adapter, doesn't for LG
*by P***O on November 11, 2024*

### ⭐ Doesn't work with LG TV. RXD and TXD are reversed.
*by A***E on July 23, 2023*

Same problem reported as another review. Title should not say it works with LG TV, which requires crossover RXD (Tip), TXD (Ring), GND (Sleeve). Haven't found any direct adapters, just 3.5 to DB9, no USB, then use a crossover DB9 adapter.

### ⭐⭐⭐ Inverted TTL logic for Bose!!!
*by L***E on March 5, 2025*

Needed to connect to BOSE stereo, did not fit the bill. As others point out the left and right channels are reserved. The voltage levels are correctly in the 0-5V range but INVERTED for what BOSE uses. This cable outputs 5V idle with 0V signal, however the BOSE needed 0V idle with 5V signals. I tried to find a way to invert this signal using driver settings but came up empty handed. Disappointed because I bought this cable because I wanted to do away with external converters, but maybe others can learn from my mistake. Edit: I actually found a linux program ft232r_prog that reprograms the FT UART to invert the RX and TX signals. I still had to swap the TX/RX wires.
