#### Important Notes

To properly operate the Raindancer Beacon, it has to be connected to an adequate power supply via the POWER-IN field (12/24V DC is recommended). The USB port on the front casing is not suitable.  
When a single power supply is used to power both, Raindancer Beacon and peripherals, the GND lines should be tied together.

<p class="callout danger">Power down all systems (Raindancer Beacon, sensors/actuators) before connecting to the Raindancer Beacon via USB, internal components may irreparably take damage otherwise!</p>

#### Analog Field Section

- Analog Pins can be individually configured, according to the requirements of the devices to be connected: 0-10V or 4-20mA. By default, all Analog Pins are preconfigured to 4-20mA. An alternate configurations can be set using the web-portal.

Pin Assignment and Value Ranges when Used as Pump Control Unit:

- The value ranges can be individually adjusted using the web-portal.

#### Digital Field Section

- Output can be configured as a permanent or pulsed signal (125ms – 256s).   
    Signal configuration can be adjusted using the web-portal.
- Pulse counter (using level raise/fall, max. ca. 60Hz), e.g. for water meters on Digital Channel 8.
- Please note that floating/pulsing input voltages may be transmitted as highly fluctuating input signals, triggering associated actions (e.g. error notification).

#### Error Codes

- By combining the three main Error Codes using Digital Channels 4 – 6, four additional states, up to a total of 7, can be transmitted.
- • The textual interpretations of the Error Codes can be customized individually using the web-portal.
