11. Universal output
The output can be used as serial interface or as analog output (0-1V).
If none of both is needed, we suggest switching the output off, because battery
life then is extended.
11.1 Serial Interface
By means of the serial interface and a suitable electrically isolated interface
adapter (HND-Z031, HND-Z032) the device can be connected to a computer for
data transfer. To avoid transmission errors, there are several security checks
implemented e.g. CRC.
The following standard software packages are available:
BUS-S20M:
20-channel software to display the measuring values
The device has 2 channels:
- Channel 1: actual-value-channel pH, mV or rH and base address
- Channel 2: temperature value
The unit of all transmitter values (including measuring / boundary values) is
the unit of corresponding displayed values.
11.2 Analog Output
An analog voltage 0-1 V can be connected at the universal output connector
(mode: “Out dAC”).
The analog output cannot be scaled.

Please take care not to load the analog output too healy, otherwise the output
value will be distorted and the power consumption will rise. Loads up to approx.
10 kOhm are unproblematic.
If the displayed value goes beyond the fixed value, the output voltage will be 1 V.
If the displayed value falls below the fixed value, the output voltage will be 0 V.
In error case (Err.1, Err.2, etc.) the output voltage will be slightly higher than 1 V.
plug wiring:
Attention!
The 3rd contact has to
be left floating!
Only stereo plugs are
allowed!
