6.1

Analog voltage outputs

Each of the two analog voltage outputs can be configured to one of the following:



True North offset.



Tilt X.



Tilt Y.

Both analog voltage signals are digitally generated by means of a 12-bit 0-5V
Digital to Analog Converter and subsequently conditioned by an analog output
stage with 220Ω output resistance. The output is constrained to the range 0.5-
4.5V, leading to the following characteristics:

Variable

Variable range

True North offset

0…360º

0.5…4.5V

0.11º

Tilt X / Tilt Y

-90…90º

0.5…4.5V

0.05º

The first analog voltage output, Out (V1+), is located at pin 1.

The second analog voltage output, Out (V2+), is located at pin 5.

Both analog outputs reference its voltage to Out (V-), located at pin 8. In order to
ensure proper signal integrity, Out (V-) must never be connected to Supply(-) on
the sensor side. Otherwise the voltage drop in the negative power line will affect
the accuracy of the measurement.
