Device LEDs

The pine.box has two LED indicators for the device status

  • Power LED:
    • OFF: No power supply, power supply out of specified range, internal power supply malfunction
    • Green: Power supply good
  • System LED:
    • Off: System not running

PinSignalDescription
1L+24 Volt power supply to device (will be switched by pine.box). The pine.box can deliver max. 0,5A per port on this pin. The pin is overload protected.
2I/QDigital Input/Output – not supported by pine.box
3L-Device GND
Please note that the GND potential at the 24V input connector and the GND potential at the port connectors differ due to internal filters.
4C/QCommunication signal (SIO- Standard Input/Output). The pine.box can deliver max. 150mA per port on this pin. The pin is overload protected.

The pine.box supports communication speeds COM1 and COM2. The speed is auto-detected.COM3 speed is not supported.

Device Port Indicators

Each port has one LED indicator located at the port.

  • Off: Port power not enabled
  • Green: Port power enabled, communication to connected device ok
  • Blinking Red/Green: Port power enabled, no device detected at port
  • Blinking Green: Port enabled, device detected but device configuration faulty (e.g., wrong IODD file loaded)
