Keypad
UP / DOWN: Press one of these keys to select the probe input
for the display and functions. When the function menu is active,
use these keys to navigate the menu, make a selection or to
change a number on the display.
ENTER: When the menu is active, press
this key to confirm a selection.
To prevent unauthorized or accidental changes, access from
the keypad to the calibration functions can be blocked out
when configuring the HygroFlex with the HW4 software. This
also prevents access to the calibration functions with the
HygroPalm calibrator.

menu items appear on the LCD message line. Press this key again
to exit the menu
2.5 Serial interface (HygroFlex 2 and 3)
Both the HygroFlex 2 and 3 have an external receptacle (located on the connector plate) that
provides both a RS-232 and a RS-485 interface. A special connector matching this receptacle is
shipped with the HygroFlex.
Serial interface settings
The HygroFlex transmitter is compatible with the ROTRONIC HW4 software (version 1.2.2 or
higher) and backward compatible with the ROTRONIC HW3 software. Each software uses a
different communications protocol and different settings regarding the parity, number of data bits
and number of stop bits. When interrogated, the HygroFlex automatically recognizes which
software and which protocol is being used. This allows using the HygroFlex with either HW3 or
HW4 without requiring a manual configuration of the HygroFlex serial settings.
When used with HW4, the HygroFlex automatically sets its serial interface as follows:
Parity :
none
Data bits
: 8
Stop bits
: 1
