4 Operation and Configuration
RHE2X transmitters can be interrogated and configured in one of three ways:
1) Manually through the front panel user interface
Each RHE2X transmitter has a user operation interface consisting of a color LCD screen
and three pushbuttons. The screen and pushbuttons are used to navigate through a
hierarchical menu structure that logically and intuitively organizes the various features
and functions available within the programming set supplied with the instrument. This
chapter gives a short introduction into operation of the RHE21 through the front panel
user interface. For more detailed information, please refer to the RHE2X Desktop
Reference Manual.
2) By RHECom PC software through the RS485 serial port
See Chapter 5 for details
3) Through Modbus commands via the RS485 serial port
See Chapter 5 for details
4.1 Function of the Pushbuttons
RHE2X transmitters are operated through three front panel pushbuttons. These are labeled
“ESC” [X], “NEXT” [>], and “ENTER” [

]. The function of these pushbuttons depends upon the
currently displayed screen.
The following table details button function in specific situations.
Table 7: Functions of the Pushbuttons
Button Situation Function
ESC Menu Navigation Navigates to the menu one level up
Number Input Exits number input field and returns to the associated menu window without
saving any changes
NEXT Menu Navigation Selects the next menu item
During Number Input Increments the number at the cursor position by one. Number increment is
circular: a ‘9’ increments to ‘0’ for decimal numbers, ‘F’ increments to ‘0’ for
hexadecimal numbers (used for service password)
Number Sign Change Changes ‘+’ to ‘-’ and vice versa. When entering a number with a sign
character, the cursor will start at the first number character to the right of
the sign character in the field. In order to reach the sign character, it is
necessary to traverse all the way to the rightmost character and then start
at the beginning of the input field again
Decimal Point Position
Change Shifts the decimal point and cursor position one place to the right
End of input line The entire number will flash upon pressing ENTER at the rightmost character
in an input field. Pressing NEXT when the field is flashing will return the
cursor to the start of the input line
ENTER Menu Navigation Navigates to the menu one level down or enters an input screen
During Number, Sign or
Decimal Point entry/
change Moves the cursor one character to the right in an input field. Note that when
a number is entered that is not in the parameters’ acceptable range, the field
will change to inverse colors (light on dark instead of dark on light). When a
number is not within an acceptable range, pressing ENTER at the rightmost
character in the field will return the cursor to the leftmost position in the
field for re-editing.
