Controller not responding

ZRS serial controller not responding to baud rate in NCD Base software. I have tried both onboard com port and a USB-serial device.
When i choose com port and baud rate and click ok i see the Rx light blink but software comes back and says controller did not respond.

Hi Keith,

How are you powering the relay board? Are you using a 12VDC power supply we provided? Can you also send a photo of the board powered up?
