Enhancements and Improvements

Support of the MxMessageSystem

Starting with firmware release, the MxDisplay supports the MxMessageSystem. This adds several new features that are described in more detail further down.

To configure the MxMessageSystem, open the new Settings > Installation > MxMessageSystem dialog. When configuring, make sure that the connection data is identical to the connection data on the door stations or cameras that are exchanging messages with the MxDisplay device. To define the messages themselves, open the new Settings > Installation > MxMessageSystem > MxMessages dialog.

Receiving MxMessageSystem Messages

The MxDisplay device can react to MxMessageSystem messages. This means that you can execute softbutton functions from an MxMessageSystem message to switch to the Live view or to open a door, for example. Note that you also need to specify the MxMessage that should trigger the softbutton function. In addition, a softbutton can also use the new MxMessageSystem function to visualize messages that contain a parameter, e.g., you can show the current state of the lights (on/off) on the display.

Sending MxMessageSystem Messages

The custom softbuttons can also be used to send messages using the MxMessageSystem. You can thus send messages via the door station to a connected MX-Output-Box to open a gate or to switch the lights on or off. When defining the softbuttons, select the message that will be sent using the new MxMessageSystem function.

"Room Thermostat" Feature

This firmware release also includes the new room thermostat feature that can control one or more remote-controlled heating valves depending on the current room temperature. This feature has the following properties (only the most important ones listed):

To configure the feature, you should create a new view in MxDisplay (e.g., by the name of "Room Temperature") that contains a softbutton of the new Room Temperature function type. Once you tap the button, you can set all relevant parameters in the Room Thermostat dialog. Once you have completed the configuration, all values will be displayed in the new view and the room temperature control is valid.

For more information on this new feature, please consult the Configure an MxDisplay to Control Thermostats tutorial under Support > Download Center > Software Downloads > MxDisplay in the Application Tutorials section.

Doorbell Signaling Using MxMessageSystem Messages (for "Large Installations")

A door station with a KeypadRFID module can now send a message to all connected MxDisplay devices when entering a specific combination of digits. This will prompt the MxDisplay device to ring that had been configured to respond to this combination of digits. The device will then execute the other functions as defined (show live image, activate intercom, open door, switch lights). In contrast to the "classic method" used before, no permanent connection between the MxDisplay devices and the door station (via the internal "EventStream") is required. This allows connecting virtually any number of MxDisplay devices to one door station.

After properly configuring the MxMessageSystem (see above) and defining a message that is used for receiving the specified combination of digits, the signaling on the door station or camera is actually configured on the MxDisplay device in the new Settings > Installation > Camera Configuration > MxMessages dialog. Make sure to define one receive message of the state of the "bell button" and one send message each for the "door opener" function and the "light switch" function, respectively.

The "bell parameter" should be set to the combination of digits and the letter for the function button that should be pressed on the KeypadRFID to trigger the doorbell message (B = bell button, M = mailbox button, K = key button, O = OK button, E = ESC button, Example: 2121B). Ensure that the message IDs correspond to those sent by the KeypadRFID and received by the MxDoorMaster. Among other things, the KeypadRFID needs to have a properly configured "Keypad" message of the "Function Code" type, among other things.

Software Release V2.1.0.33 for MxDisplay+

Creation Date: 2017-10-10

Publishing Date: 2017-10-20

Important Notes:

Enhancements and Improvements

New Floor Call Feature (Uses the Signal Input/Output Pins of the MxDisplay+)

Starting with firmware release 2.1.0.x, the MxDisplay+ provides a storey call functionality. It is intended for scenarios in which both – a main door at a building and an apartment door on a floor inside – are present. The main door is equipped with a door station that is controlled by an MxDisplay+ as intercom, while the apartment door is connected directly to the MxDisplay+. The two wires of the apartment doorbell and the wires of any door contacts or door lock contacts are connected to the signal inputs, the electrical door opener is connected to the signal output of the MxDisplay+. The MxDisplay+ will indicate the doorbell that had been pressed, allowing you to open the corresponding door.

To configure this feature, open the new Settings > Installation > Door Configuration > Storey Call dialog. For additional details to the connections that are required for this feature, please read the document Quick Install MxDisplay+, which is available on the MOBOTIX website in the section.

External Temperature Sensor

This firmware supports an external temperature sensor that has been connected to the separate input terminals T+/T- of the MxDisplay+. The following temperature sensors can be used:

To select the attached temperature sensor, open the Settings > Installation > Display Configuration > Temperature Sensor dialog.

MxDisplay Software-Release V1.0.2.16

Creation Date: 2015-06-18

Publishing Date: 2015-06-26

Important Notes:

Enhancements and Improvements

Redesigned "Access Control" Dialog, Tool Tips

The Settings > Access Control dialog has been completely redesigned. The menu structure, in particular, has been improved when adding new RFID cards. In addition, the dialog has been improved for adding PINs, users, parties and door stations that opens when tapping the "+" icon: When tapping and holding an icon, a text explains the icon's function. The same applies to all other dialogs that contain icons.

If a PIN has been set for an RFID card in the access control, the following applies when trying to gain access using the card: If a KeypadRFID controls the access, you also need to enter the assigned PIN, whereas a BellRFID will grant access using only the card.

New Functions for Softbuttons

Two new functions are available when defining "function icons":

If function icons have been created, the tool bar beneath the live image shows an additional "checkerboard" icon. Tap on this icon to see and to use the defined function icons.

Note: To activate and define function icons, tap and hold the Home button in the MxDisplay main menu.

Enhanced Menus and Screens

MxDisplay Features

"A Smartphone On the Wall"

That's the first impression of the new wall-mounted display from MOBOTIX. It can be integrated flush with the wall, comes in a stylish design in black or white and users can operate it using gestures, just like a modern smartphone. With just a few swipes, the user can look at an overview of the cameras in the house, retrieve the latest video messages of the door intercoms or create a new access transponder for a visitor.

The MxDisplay is extremely easy to operate and serves as an intercom for the video door station. Regardless of what menu the user is in, tapping the key icon immediately shows the live image of the door station. Tapping and holding opens the door. If necessary, you can increase the security by assigning a PIN or RFID transponder.

Main Features

Besides the features mentioned above, the MxDisplay has many more features; the most important ones are listed in the following:
