Connect board to USB, modify if necessary MAC and IP address and upload to board

Connect to your Router or PC Network Card and check for PING

UDP Commands:

FF 00 00 - Status Read command

FF 01 00 - Relay 1 OFF command
FF 01 01 - Relay 1 ON command
FF 02 00 - Relay 2 OFF command
FF 02 01 - Relay 2 ON command
FF 03 00 - Relay 3 OFF command
FF 03 01 - Relay 3 ON command
FF 04 00 - Relay 4 OFF command
FF 04 01 - Relay 4 ON command

UDP Test Software example including source code (C#)

KMTronic DINo 4 Relay UDP Test Software.zip
