Page 14 6.3 UNDER-TABLE/TABLETOP MOUNTING There are two recesses on the top and bottom of the housing, each with two M3 threaded holes, for under-table/tabletop mounting. Attach the two included mounting plates to the top or bottom using the included M3 countersunk screws. Now the device can be mounted in the desired position (see illustration, mounting screws not included).
Page 15 7.1 THE FIRST STEPS To access the MSMP web application, the device must be connected either wirelessly (Wi-Fi) or to the network via cable (RJ-45 port). • Cable (Ethernet connection): The MSMP is standard configured in DHCP mode, i.e. an IP address is automatically assigned.
Page 16 IP (DHCP client): 192.168.192.1 Wi-Fi network IP (DHCP server): 192.168.192.2 IP (DHCP client): 192.168.192.100 Illustration: Example of connection to a local network via Wi-Fi network interface (wireless) The MSMP uses mDNS technology to enable intuitive access to it via a web browser in the same local network (LAN).

The RELOAD button can be used to reload the current source. PRESETS: Used to select one of the available presets. The RELOAD button can be used to reload the current preset.
Page 20 ATTENTION: If a file of short duration is to be played (e.g. a ringtone of 2–3 seconds) and the transition mode XFADE is combined with the repeat mode REPEAT ONE/ALL, special attention must be paid to the playback times of the files and transitions, as unexpected behaviour could occur.
Page 21 7.2.2 PRESETS Up to 20 presets or user configurations can be created in the MSMP. If a preset saved in the device is accessed later, all the settings saved in it are restored. Illustration: Example of the configuration of a preset HEADER: All 20 presets are displayed here, which have the following standard designations: P01, P02...P20.
Page 22 NAME: Name of the preset. This name appears in the preset list on the PLAYERpage, in the header of the PRESETS page, and in the LD Systems QUESTRAapplication. ENABLED EVENTS: Activates/deactivates the events initiated by the General Purpose Inputs (GPIs) and the event initiated by silence detection in the preset.
Page 23 Source path/url field as soon as the corresponding preset is accessed. • Media alias: Alias name of the source saved in the preset (Source path/url). It can also be used to access this medium directly from any preset on the player side or in the LD Systems QUESTRA application.

If, for example, the days from Monday to Friday are selected (working days), the configured event is not initiated on Saturdays and Sundays (weekends).
Page 32 Illustration: Example of a daily repetition • ”The event will finish at” specifies the time at which the calendar event will be executed for the last time on each day. This parameter cannot be configured (read-only). It is only intended as a guide and should help the user to optimise the configuration of the “Interval”...
Page 33 7.2.4.5 ALL ABOUT PRIORITIES Calendar events have a lower priority than events that are initiated via GPI. Different priority levels can therefore be defined. In retail, for example, calendar events can be used to initiate special offer announcements, while GPI events are used to initiate emergency announcements, e.g. for evacuation. In contrast, a higher index determines the priority if two calendar events are initiated simultaneously.
Page 34 7.2.4.6.1 CALENDAR FOR BACKGROUND MUSIC Two calendar events are created: one to load and play the stream, the second to pause playback. The calendar is activated and given a unique name. As no specific start date is specified, we leave the “START DATE” field at its default value so that the event is active as soon as the changes are applied.
Page 35 The action of loading and playing the specified stream is configured. The configuration of the calendar event that is to stop the playback of the background music is carried out in the same way, with the difference that the action to be carried out now consists of stopping (STOP) the playback.
Page 37 7.2.4.6.2 CALENDAR FOR CLOSING TIME ANNOUNCEMENTS The closing time should be announced every day 15 minutes before closing (pre-recorded announcement). A reminder should be played five minutes before closing. The announcement should be made twice each day: 15 minutes before closing (7:45 p.m.) and again 5 minutes before closing time (7:55 p.m.).
Page 38 Finally, the announcement saved on the SD card ("mmc://...") is prioritised and initiated.
Page 39 7.2.4.7 CALENDAR FOR THE CHRISTMAS CAMPAIGN As a specific calendar period is specified in this case (15/12/21 to 15/01/22), an end date must be configured. This is done by selecting CUSTOM END DATE and correctly configuring the End date and End time parameters.
Page 40 As far as the repeats are concerned, the announcement should be made every 30 minutes, and we know that the shop closes at 8:00 p.m. As no more audio content is broadcast at 8:00 p.m., we set the number of repetitions so that the event is carried out for the last time 30 minutes before closing time.
Page 41 Finally, the announcement saved on the USB card (“usb://...”) is prioritised and initiated. 7.2.5 CLOUD DISC SYNC The CLOUD DISK SYNC module enables the device to download external audio content to local storage media (USB/uSD). If this module is activated, it carries out a daily check of a remote location where the audio content is hosted, compares it with the current content of the local storage media (USB/uSD) and, if necessary (if differences are detected), synchronises the local content so that it becomes an exact copy of the external content.

Page 45 7.2.7 SCRIPTS/LUA A script is a simple programme, a file with commands, written by the user in the programming language LUA (https://www.lua.org/). Each script can be seen as a kind of script that the player is supposed to realise, i.e. a series of pre- programmed tasks to be performed as soon as the corresponding trigger is received.
Page 46 Figure: Available trigger pulses ॰ ON BOOT: Start-up tasks can be configured during device activation. ॰ ON EVENT: With activation of a GPI event (GPI1 or GPI2), in addition to the silence detection event (SILENCE) ॰ ON PRESET: After loading a preset. One of the 20 presets must be selected, which then activates the script.
Page 47 • Script Status: Shows the status of the script: RUNNING (flashing) when the script is being executed or STOPPED (permanently lit) when it has finished or stopped executing. • Script Output: Output/return value of the script. Output messages can be written to then appear on the display.
Page 48 7.2.7.1 EXAMPLE SCRIPT02: Automatic playback of the content of the uSD card as soon as it is inserted There are applications in which the local storage medium changes depending on the user. In a gym, for example, each trainer changes the music according to their specific training session. In other words, each trainer connects their own USB storage device or uSD card to play their specific audio content.
Page 49 7.2.7.2 EXAMPLE SCRIPT04: Playing Internet radio after restoring the Internet connection The following script accesses a preset as soon as an available Internet connection (WAN) is detected. This can be interesting when used with the silence detection event: The player is playing an Internet radio programme and suddenly loses the connection to the radio station due to a network problem.

Page 59 7.4.1.2 TIME SYNCHRONISATION Illustration: Name and time, time synchronisation This option allows you to enable or disable synchronisation of the time with an NTP server. In addition, the servers that are eligible for synchronisation can be managed here. The MSMP is equipped with an internal clock, which ensures that the time setting is not lost if the power supply or the connection to the NTP server is interrupted.

Page 63 7.4.4 USB/MMC SETTINGS Used to display the storage space used in the local storage media and to manage the encryption function if there is a need to secure the musical content stored on the uSD card, USB device, or similar for reasons of security or data protection.
Page 64 Please note the following considerations regarding the encryption function: • The encryption process is destructive, as formatting the external medium deletes all files stored on it. • If this function is enabled, any other external medium (uSD or USB) that is inserted into the corres- ponding slot and does not containthe encryption keys will be encrypted, i.e.
Page 65 • Apply Encrypt now: The storage medium is encrypted immediately. • Disk Usage: Storage capacity of the medium (MB) and used storage space (%) on the uSD card or USB device. If no storage medium is found, the message “NO DISK” appears. 7.4.5 REGISTER The log file(REGISTER) makes detailed monitoring of the player’s activities possible.
Page 66 Illustration: Reboot 7.5 CONFIGURATION OF AN SSH SERVER FOR STORE AND FORWARD (RSYNC) The MSMP’s Cloud Disk Sync, Store and Forward module enables the device to download external audio content to local storage media (USB/uSD). If it is activated, it carries out a daily check of a remote location where the audio content is hosted, compares it with the current content of the local storage media (USB/uSD) and, if necessary (if differences are detected), synchronises the local content so that it becomes an exact copy of the external content.

Page 68 7.5.1 CONTENT GROUPS A content group is a group of devices that synchronise the same audio content using the Store and Forward service. A separate user must be created for each content group. A device that has been assigned to a specific content group can thus only access the content assigned to this group and not other content. This procedure is for safety reasons.
