Review: Not compatible for VFD display - Not compatible for VFD display
Review: No manufacturer documentation online, a hobbyist has published information that is helpful but incomplete, and having gotten the device to work once it has repeatedly lost its settings and finally will not accept new settings. It's not worth messing with and I regret the purchase.

No manufacturer documentation online, a hobbyist has published information that is helpful but incomplete, and having gotten the device to work once it has repeatedly lost its settings and finally will not accept new settings. It's not worth messing with and I regret the purchase.

### ⭐⭐⭐⭐ Review
*by M***A on 6 November 2021*

I spent days trying to communicate this display with Modbus RTU. Poor documentation. Finally, browsing in other websites I found some details about modbus registers to be pointed to (40001 to 40007). The device doesn't respond to Modbus requests, it only accepts commands to change the value displayed, decimal point, brightness and other setting modifications. The device has a jumper inside which I have not idea what is for.
