4.5.13. Modbus Setting: Format (Channel One):
Activating the MENU switch twelve times will display the default Modbus setting Format “F8N1” (8-N-
1). Using the UP/DOWN switches, the format can be selected for the Modbus communication interface.
The selectable formats are: 8-N-1, 8-E-1, 8-O-1, or 8-N-(bits- parity-stop bits).
Activating the ENTER switch having changed the status ON/OFF, will flash “SAVE” on the display.
Confirm the SAVE action by activating the ENTER switch once more. Activating the MENU switch
while “SAVE” is flashing, will discard the SAVE and switch the unit back to normal operation. If ENTER
is activated the unit will display “DONE” to confirm that the changes have been saved and return to
normal operation. The operator can change the format settings and if desired move to the next item
(Address) in the menu structure by activating the MENU switch straight after the change. The change
will be saved at a later stage by activating the ENTER switch at any point in the menu structure. If no
switch is activated for 60 seconds, the detector will return to normal operation without saving the
changed settings.
