2 years ago Hi Alex, it looks like the LED circuitry on the TXIO board will not work with active-low signals. Very sorry about this. We designed the board with active-high signals in mind, and did not expect to have it interface with an active-low style transmitter (didn't know they existed until yours). At this point I don't have a solution for you.

2 years ago No problem - just wanted to check. However I would suggest LEDs-off could be a useful option in the config-file.

Our LEDs work as expected (green on, blue flashing) with the following settings: gpio_bank_high RXA gpio_bank_low TXA
When we switch them (to provide the T/R signal polarity required by Wallops transmitters) all four LEDs light up continuously. However the radar appears to operate fine.
