This page is about connecting the P/P3-Roc to your computer. It roughly covers connecting the bus between the nodes. For electronic details see the P-Roc section in the pinballmakers.com Wiki.
If you got a P-Roc just connect it to your computer using USB.
Then connect switches and driver according to the manual (see /hardware/existing_machines/index for specific machines). If you are using a PD-Master board see below for switches and drivers.
mpf hardware scan </running/commands/hardware> will show the firmware version and revision of your P-Roc if it is connected correctly.
If you got a P3-Roc just connect it to your computer using USB.
Connect all your SW-16 boards to the switch bus and all your PD-16 and PD-8x8 boards to your driver bus. Use twisted wires but connect + to + and - to - on all nodes.
mpf hardware scan </running/commands/hardware> will show the firmware version and revision of your P3-Roc if it is connected correctly.
Set a unique address on every SW-16 board on your bus. Those addresses can overlap with the driver addresses. It does not matter on which of the two switch busses the boards are connected. Terminate the bus at the last board. See switches_p3_roc for how to configure those boards.
You can list all SW-16 using mpf hardware scan </running/commands/hardware>:
$ mpf hardware scan
Firmware Version: 2 Firmware Revision: 6 Hardware Board ID: 1
SW-16 boards found:
- Board: 0 Switches: 16 Device Type: A3 Board ID: 0
- Board: 1 Switches: 16 Device Type: A3 Board ID: 1
- Board: 2 Switches: 16 Device Type: A4 Board ID: 2
Set a unique address on every PD-16/PD-8x8 board on your bus. Those addresses can overlap with the switch addresses. However, they overlap with the PD-LED addresses so plan accordingly. It does not matter on which of the two driver busses the boards are connected. Terminate the bus at the last board. See drivers and lights for how to configure those boards.
MPF and the P3-Roc do not know if those boards are connected as the communication is one-way only.
