Point your miners to the IP address of your Start9 Server followed by the port of the Datum-Gateway service. This is 23334 by default so in your miner UI under "Stratum URL"/"Host"/"Pool"/similar you will enter something like this:
stratum+tcp://192.168.x.y:23334 or stratum+tcp://10.0.0.x:23334 replacing x/y as appropriate.
Under "Username"/"Worker" enter a Bitcoin address. This is where your OCEAN rewards will go. You can append this with unique worker information if desired.
