Display

General

The display of the Jellox Node is only designed to show the current measurement values and various status information. The device cannot be operated via the display. The display is activated by briefly holding the magnet (approx. 1 sec.) to the reed switch (see Reed switch). The display then remains active for 20 sec. , showing first the boot screen for 1 sec. (see Boot screen) and then consecutively the tabs with information about the Jellox Node itself and the sensor modules.Using the solenoid switch you can disable automatic switching between the tabs and switch manually between the display screens (see Reed switch). The "detected hold of the reed switch" symbol is displayed in the status bar for as long as the MDN Magnet (206.803) is held to the corresponding position on the Jellox Node (see Operating elements).

1	Status bar	3	Information about the current tab
2	Display of the available tabs with specific information	4	Footer of the current tab

The tab on which information is currently shown on the display is highlighted by a white background. The background of the other tabs is black, provided no error has occurred with the respective components (Jellox Node  or sensor module) of which they contain the information. The fact that one of the tabs not currently displayed contains an error code can be recognised by the red background. If the display is switched to a tab that contains an error code, the colour of the icon in the tab changes from white to black. A list of possible error codes is provided in chapter Error codes.

Tab with valid information

Tab with error code

1	Current tab with valid informationen	4	Current tab with error code
2	Inactive tab with valid informationen	5	Error code (see Error codes)
3	Inactive tab with error code

Status bar

The status bar is located at the top border of the display and shows information about the network connection, mobile network connection, radio connection and the state of charge.

1	Information about the nework connection
		field strength of the mobile network signal during the last connection
		transport mode activated
2	Status of the mobile network connection
		mobile connection disconnected; wait for next connection establishment
	(blinking)	connecting
		connection to the myDatanet server established
		last connection failed
3	Status of the local radio connection
		establishing local radio connection to the sensor modules
4	Status of the reed switch
		reed switch not actuated
		detected hold of the reed switch
5	current state of charge of the battery of the Jellox Node . To the left, the state of charge (SOC) is displayed in %
		State of Charge >= 90 %
		State of Charge >= 40 %
		State of Charge >= 10 %
		State of Charge < 9 %

Information about the Jellox Node

1	Brief designation of the IoT application installed on the device	4	remaining time until the next battery replacement of the Jellox Node
2	Current software version installed on the measurement controller	5	Temperature inside the housing of the device
3	Version number of the IoT application that is currently installed on the device

Information about the remote sensor modules

1	Indicates sensor category (e.g. velocity sensor) of the sensor module for which the information is displayed	5	Serial number of the sensor module
2	Current level1)	6	Remaining time until the next battery replacement of the sensor module
3	Unit of length (mm, cm or m) selected via the server interface	7	Temperature of the electronics of the sensor module
4	Product designation of the sensor module (as indicated on the type plate)

¹⁾ If the firmware of the sensor module is being updated, the message "Update" is displayed instead of the level.
