Each board includes an 8-position DIP switch, which is used to set the ID of the board in question, to terminate a chain of boards (DIP 8), and set some additional settings.

	Each board needs a unique ID ''per serial chain'' - ie. you can have two ''Board 0''s as long as they are on different chains. '''DIP 1-6''' sets the ID in '''binary''' notation, starting at zero (All Off). So if you want to set the board ID to 5, you would set DIP 1 and 4 to ''On''. Or if you want to set the board ID to 0, leave all six ''Off''. If the board is the last board in the chain, set DIP 8 to ''On'' as well to terminate the serial chain. Boards connected earlier in the chain should have DIP 8 ''Off''.		Each board needs a unique ID ''per serial chain'' - ie. you can have two ''Board 0''s as long as they are on different chains.

	In this diagram, it shows the serial connections between the ''P3-ROC'', two ''SW-16''s, a ''PD-LED'' and a ''PD-16''. The ''SW-16s'' are connected to one of the two ''Serial Switch'' connectors while the ''PD-LED'' and ''PD-16'' are connected to one of the two ''Serial Driver'' connectors. Note how the pinouts on ''Switch'' and ''Driver'' are different.		In this diagram, it shows the serial connections between the ''P3-ROC'', two ''SW-16''s, a ''PD-LED'' and a ''PD-16''.

It also shows how the DIP switches are set on each board to ID them, as well as to terminate the chain on the last board (DIP-8). For this example, the boards are numbered '''ID 1''' and '''ID 2''' in each chain, with the last board terminated via '''DIP 8'''.

			=== Wiring Examples ===
			There are a number of ways to connect the '''P3-ROC''' boards to your machine but the following are some basic configurations to illustrate serial, power and device connections.

			'''Important Note:''' When wiring up multiple power supplies for logic, solenoids and LEDs, it is '''critical''' to connect all grounds together at the power supplies (or use the '''Power Entry''' board) to avoid a potential floating ground issue that can easily destroy your boards.
