I’m trying to get the SLB-EXT to work with a new HY02D211B VFD but they don’t seem to want to communicate using MODBUS. I see all of the documentation with ‘Huangyang’ on the list of VFDs to select from but all I have is PWM, PWM2 and H-100. (is that not in the firmware anymore?) I’ve tried swapping the A-B, RS+, RS- wires and that doesn’t change anything, as well as verify the baud, address, etc, match in the controller and the VFD. When the board powers up (with the VFD already booted) the bottom communication LED blinks for a few seconds and then stays off and the top light never blinks (I’m guessing there’s a communication mismatch somewhere). Would it just be easier to use the PWM settings like I have on my Masso G3? The MODBUS thing sounds nice with only being 2 wires. Here is the $i for reference:

If anyone has some insight that would be great, thanks.
