Keyboard Operation - Relay MR005DL User Manual

Access by ID: The M-Bus Display supports a different setup of the passcode mode from the
menu „Display config. – Passcode mode". If this mode is activated, the user (tenant) can make
a readout limited to his own meter(s). After first key-press the tenant is requested to type in the
ID (identification no.) of the required slave. Afterwards this single meter is read and its data
displayed. Please note that only meters which support secondary addressing are readable in
this mode. The access to the menu is possible in this mode after input of the ID 00000000 and
login with the described passcodes.
Access by Adr: This mode allows a direct readout of meters using their primary addresses
without any login procedure. This mode is similar to "Access by ID". The primary address for
global readout 254 is used by default. So by just pressing the E key you can read a meter if
there is only one meter connected. The cursor keys allow editing the address. You can leave
the input mask and step to the passcode request by pressing the  key three times.

5 Keyboard operation

Basics:
Besides the control using FService the device includes 4 keys and a backlighted display for
comfortable, local access to all functions. The buttons give a very precise, mechanical feedback
and each input is acknowledged by an acoustic signal (beep). Execution of menu entries and
input of numbers are described later. The device automatically returns to inactive state after
some minutes without input.
Selection of a menu entry:
An arrow marks the active menu entry on the LCD. The arrow is moved down with the  key
(black) and up with the  key (grey). Pressing the E button (blue) executes the currently
selected menu entry. The C button (red) cancels the input and exits from the menu.
 key
Input of numbers:
The  button increments the number of the active position by one. After the 0 it restarts with the
9 again. The  key moves the cursor to the next position on the right. The active position is
blinking. After pressing  at the most right digit the cursor moves to the most left digit. The E
button ends and acknowledges the input regardless of the current position. You can cancel the
input with the C key.

After input of passcode and confirming with the E key the main
menu is activated. You can always see two entries of this
menu. The first displayed lines are "Readout of all" and "Single
readout". By pushing the  button the LCD scrolls to the next
part of the menu. In this example the line "Single readout" will
then be marked with the arrow. This submenu would be entered
by pressing the E key.
