Powering the external ports

If a payload wired into an external port does nothing, the usual reason is that the port's power is off. Plugging the connector in does not energise the port — you switch it on in the app.

Wiring and pin assignments are in External ports; the cables are listed under Accessories.

Where to switch it on

All external port power is switched in Maintenance → Power / System, which everyone can open. The ports you plug into from outside are gathered in the Top ports section. The whole screen is described in Maintenance › Power / System.

Switching on a 48 V port

Ports that carry raw battery voltage — POWER (2-pin) and PWR-CAN (4-pin) — sit on the 48 V rails.

1. Open Maintenance → Power / System.
2. Press Turn on on the EXTERN (48V) row in the Top ports section — the power that goes out to the external expansion ports. CAN-FD robots have no such row, only ARM · ADDON (48V).
3. Confirm with Turn on in the Turn this on? dialog.
4. Check that the live voltage on that row comes up.

If your add-on sits on ARM · ADDON (48V), switch that row instead.

⚠

CAUTION

ARM · ADDON (48V) is one PDU port shared by the arm and the add-on. Turning this rail off also cuts arm power, so make sure the arm is stopped before you switch it.

The 48 V rails put out raw battery voltage, which moves between 42.0 V and 58.4 V with the state of charge. Add your own converter if the payload needs a regulated supply.

Switching on a 12 V port

Tap the 12V port 1–4 toggles in the Top ports section. The ports are named by number only, because what is plugged into them differs from robot to robot. A picture of which connector is which will be added under ? Help next to the section title. Turning a port off asks Turn this off? first — if a network device is plugged into it, the app may lose its connection.

It is on but still does not work

• The toggle is grayed out and will not press — the rail state has not arrived yet. Check the robot connection first (Connection).
• It does not flip immediately — the toggle shows the actual state the robot's PDU reports, and that takes about a second to come back.
• The voltage does not come up — check that the connector is seated and the cable is intact (Connector handling).
• Power is present but the device stays off — check you are within the per-port current limit: POWER 5 A, PWR-CAN 10 A, 12V/LAN 2–3 A (pin map).

Still stuck

Tell us which port you wired what into, and the voltage shown on the power screen.
