Autonomous mode 10 Autonomous mode The digital conference system provides a 100% stand alone solution and is completely self-configuring. With DIGIMIC it is easier then ever before to setup even the most complex conference systems. DIGIMIC matches digital broadcast and studio audio requirements, meeting the needs of today's conferencing world. When connected to the DCen the system can be expanded to include our conference software. TCP/ IP communication is utilized to offer microphone control and name handling as well as other conference requirements. The delegate's frontend – the microphone unit – offers a thoughtful ergonomic design enabling the delegate to concentrate on the conference. DIGIMIC wireless can be used in different system modes as described in the following: • Autonomous mode (also Multi-room mode, described in a separate chapter) • Slave mode (please refer to page 19) System overview wireless basic discussion system Figure 1 TMD/01orTM58/6ExternalPower Supply Wireless Delegate UnitsDMic with DDocDSpark Radio Transceiver Unit Connection to LS signal OUT Connection to ext . signal INWireless Chairpersons’ Unit DChair with DDocMicrophone
Autonomous mode 11 DSpark Radio Transceiver Unit The radio transceiver unit DSpark together with the docking unit DDoc ensures reliable wireless audio transmission. For basic configurations the DSpark can be used autonomously offering the most common functionalities for discussion systems. This solution offers an inexpensive first step into the wireless world of conferencing without loosing the opportunity for future system upgrading and expansion, either wired or wireless. The radio transmission is based on the unique intelligent adaptive narrow band protocol (APRON) which combines for the first time ever several wireless transmission security features within one single protocol ensuring co-existence with Wi-Fi systems and resistance to mobile phones or Bluetooth emission, also suppressing unwanted interception. The wireless DIGIMIC provides also a multi-room solution, offering the possibility of using the same system within one building in several rooms at the same time. The DSpark is equipped with four independent antennas, receiving independently the individual signals of each active microphone, providing a high audio quality and transmission reliability even under critical RF congested environments. The DSpark can also be wall mounted like shown in the next illustration. In this case also see HIGH POWER in “Settings of DSpark” next chapter. 190 mm7.48 in289 mm11.378 in289 mm11.378 in62 mm2.44 inRear side
Autonomous mode 12 Connecting the Power Supply For the basic functions of the Radio Transceiver Unit you just have to connect the external desktop power supply to the DSpark (Figure 2). Then you can start to place the wireless delegate units DMic with DDoc for your conference. Figure 2 Power Supply 05.0292 On/Off switch
Autonomous mode 13 Transmitting antenna The powerful directed transmission antenna ensures the continuous control and audio downstream to each single delegate unit within the system even over longer distances of up to 50m radius and beyond, depending on the installation environment. Adjustment of the transmitting antenna The radiating side of the transmission antenna is the curved front side. This side must be adjusted toward the room/microphone units. To avoid interference it is not recommended to adjust the front side of the transmitting antenna toward the receiving antennas. antenna front antenna back Direction of signal radiation Direction of signal radiation
Autonomous mode 14 Settings All functions are activated when pressing the corresponding push-button. The corresponding control LED will light up when a function is activated. Figure 3 For basic configurations the DSpark can be used autonomously offering the most common functionalities for discussion systems like AUT3 or PRIO. Control LED Push-button for activation Transmitting antenna Receiving antennas
Autonomous mode 15 REGISTER REGISTER can be opened (LED off) or closed (LED on). Use REGISTER open (LED off) during setup. During setup you switch on and register your units to the DSpark. The DSpark will automatically put all recognized units into an internal list. This list will be expanded as long as the register function is open (LED off). To save this list close the Register (LED on). Once the register is closed no more units can be registered to the DSpark. This function offers you the following opportunities: 1. The wireless system is now completely closed (like a wired one) and cannot be intercepted by any other wireless DIGIMIC unit. This is important because to exclude interception you have to take out the unit which are designed to work perfectly with the DIGIMIC wireless: DMic and DDoc. 2. This register function also enables to use multiple DIGIMIC wireless systems within one building by simply assign your units to the DSpark of the corresponding room (please refer to page 26 for more details) Note: The list is stored automatically. To delete the list press and hold button “register” for minimum 5 seconds. The corresponding LED will flash two times to indicate that the list is deleted. Note: You can exchange the battery pack and re-register the units which had already registered even when the register is closed. HIGH POWER With this option the power of sending is increased in the case DSpark is used as desktop. When DSpark is wall mounted, there is no need of increasing the output power. PRIOrity mode If a DChair unit is to be used, PRIO mode is available with this setting. Press button PRIO to enable this option. Maximum 2 DChair units are supported as chairpersons at the same time. They will be identified automatically. With 2 DChair units 2 active Delegate units DMic are possible at the same time. This means: 0 DChair Æ max 4 active delegates’ are possible 1 DChair Æ max 3 active delegates’ are possible 2 DChair Æ max 2 active delegates’ are possible
Autonomous mode 16 LS INTERN When active (LED on) the audio signals from the DMic units are directly routed to the DMic loudspeakers. Audio from DMic micro Audio to DMic loudspeakers (LS) Figure 4 Otherwise (LED off) external signals are routed to the DMic loudspeakers, e.g. from a mixing console like shown below. Audio from DMic micro Audio to DMic loudspeakers (LS) Figure 5
DDoc Docking Unit 17 DDoc Docking Unit The docking unit DDoc transforms the delegate unit DMic into a wireless discussion unit, replacing the tasks of a cable by its powerful rechargeable battery and the reliable and stable wireless communication protocol. DMic and DChair are delivered with a cover to protect the contact bar. Before using the DDoc the first time we recommend to check or charge the rechargeable batteries. (please refer to page 23) The transformation of the wired DIGIMIC delegate units is easily be done by unplugging the cable and sliding the DMic on the docking station DDoc. But before sliding the DMic on the docking station, it is necessary to remove the covering of the contact bar on the rear side. This is done in the way shown below: 1. Turn the DMic upside down, if there is no microphone plugged in. We recommend handling on a soft surface. 2. Press the two clips in the shown direction. 3. Turn the DMic on top, the covering should fall down. Rechargeable battery pack Antennas 2.2. Cover
DDoc Docking Unit 18 Slide the DMic on the docking station DDoc. Ensure that the unit is connected properly with the contact bar. This solution introduces unique flexibility in terms of the installation of rental and sales projects and maintains a high level of connectivity. DIGIMIC wireless is based on an intelligent transmission protocol, which assures the audio quality and reliability of a wired conference system, combined with the flexibility and freedom offered by wireless. The complete DMic Delegates Conference Unit with the DDoc Docking Unit looks like shown below. Don’t forget to assemble the microphone. DMic DDoc Contact bar
Slave mode 19 Slave mode For additional discussion functions, like Request-to-Speak-mode, name handling, robotic camera control, software interfaces or combination with wired units the DSpark can be connected easily to the DIGIMIC central control unit DCen. Only in this mode DDoc can be set into standby.

Single operation mode 21 Single operation mode The following chapter describes the operation with one DSpark in autonomous mode. System startup Before starting a conference all units have to be registered by the Radio Transceiver Unit DSpark. This is easily done by just pressing the microphone key. Please ensure that the REGISTER LED is off. Successful registration will cause the microphone ring and microphone button to flash twice. DDoc Docking Unit Before starting operation with the DIGIMIC wireless equipment make sure that the rechargeable batteries inside the DDoc units are properly charged. Otherwise the battery pack has to be charged, either in the DTray (Charging and transport tray for 10 DDoc) or with an external power supply. For successful login status see table below. Indication of battery status There are three possibilities of checking the status of the rechargeable batteries: 1) In operation Æ by a Multicolor-LED in front of the docking station. The Multicolor LED has different indication modes: White – for a few seconds ready for operation BLUE – flashing no reception, battery ok BLUE – not flashing radio reception ok, battery ok (more than 1h operation time) OFF – permanent Switches off automatically after 30 sec for power saving (standard operation mode) RED – not flashing radio reception ok, battery low RED – flashing no reception, battery low (for less than 1h operation time) Multicolor LED
Single operation mode 22 Easy rule to remember: Mode flashing or permanent Æ receiving status Color red or blue Æ status of rechargeable batteries 2) Not in operation Æ by a test key at the bottom of the battery pack. Press and hold the blue test key with a peaked object or your fingernail. The green LEDs will then indicate the current battery status in 20% increments. For example: Low battery power > 80% battery power Full battery, end of charging LEDs on Battery power Operating time 1 * 20% up to 4h 2 20 – 40% up to 8h 3 40 – 60% up to 12h 4 60 – 80% up to 16h 5 80 – 100% up to 20h * If one LED is flashing, the battery is almost empty. 3) Not in operation Æ by charging in the DTray charging tray. The status indication of the battery power is the same as shown above. The LED indication by charging the docking unit in the DTray is permanently, so you don’t have to push the test key for this purpose. Automatic switch off The DDoc switches off automatically, if: - the DMic will be disconnected from DDoc (immediately switching off) - the battery pack is removed from the DDoc unit - a switch off signal arrives from the DSpark (immediately switching off) - there is no radio communication for 30 seconds (e.g. outside the radio range) - the battery is empty Note: If you switch off the DSpark radio transceiver unit, all registered DMic / DDoc units will switch off immediately. Test key Indicator lights
Single operation mode 23 Charging of the battery pack There are two options of charging the battery pack. Charging via power supply For a quick charging of a single unit an external power supply (05.0902) is provided. You do not need to remove the battery pack from the DDoc. Just connect the plug to the connector of the DDoc. Note: The discussion function of the unit is disabled when the external power supply is connected. Charging with the external power supply is only possible if the unit is not in use. Charging via DTray Charging Tray For charging more than one battery pack an external Charging Unit DTray is provided. With DTray it is possible to charge 10 units at once. First you have to remove the battery pack from DDoc. Removing the battery pack No tools are necessary to remove the battery pack. If not already done, separate the DMic unit from the DDoc docking unit as shown below. Note: This charging solution offers you the opportunity to leave all units on the tables in your conference room. Just collect all batteries after the conference day to re-charge them. You also can just exchange low batteries (during conference) with charged one’s offering the possibility of an “unlimited” wireless conference period. Connector for power supply
Single operation mode 24 To remove the rechargeable battery pack, pick up the DDoc and turn it upside down, press the marked position and pull as shown: Never under any circumstances place the DDoc unit upside down on a table or something else. This can damage the antennas! Insert the battery pack into a free slot of the DTray charging tray. The charging time is max. 9 hours if the battery is completely empty. Specifications of the battery pack: • Lithium polymers (built in) • 3.7 VDC • 13.2 Ah Please be sure to avoid a short circuit of the electrical connections. To put back the battery pack after charging simply slide it back in the DDoc. The sophisticated design of the DDoc ensures that the battery pack is slide in always correctly. 12Press and hold herePull here

Multi room operation 26 Multi room operation The following chapter describes the operation in autonomous mode with more than one DSpark. Multi operation mode is also available for slave mode in combination with DCen (wired central unit). The setup procedure is the same. With DIGIMIC wireless it is possible to handle parallel operation of different conferences in the immediate vicinity. To enable a reliable operation each DSpark has to be configured with its own ID. Up to 5 radio channel numbers (0 to 4) are possible. Note: channel #0 is factory default Multi room operation mode examples a) Parallel operation with 3 DIGIMIC wireless systems in three conference rooms: Room 1 Room 2 Room 3radio systemnumber 0 radio systemnumber 1 radio systemnumber 2 This sample enables a reliable and autonomous operation. b) Parallel operation with more than 3 DIGIMIC wireless systems in seven rooms: Room 1radio systemnumber 0Room 2radio systemnumber 1Room 3radio systemnumber 2Room 4radio systemnumber 3Room 5radio systemnumber 4Room 6radio systemnumber 0Room 7radio systemnumber 1 This constellation enables also a reliable and autonomous operation. Please notice that room 6 has the same radio system number than room 1. It is essential that there is a greater distance to room 1.
Multi room operation 27 Radio system number For allocation of another channel number press the keys REGISTER and LS INTERN of the DSpark Radio Transceiver Unit simultaneously. This will enter the configuration mode. Figure 8 DSpark confirms this mode by blinking two times of all 4 LEDs (REGISTER + HIGH POWER + PRIO + LS INTERN). The current radio channel number is displayed. The pattern of the LEDs is shown in the table below: logical radio number LED REGISTER LED HIGH POWER LED PRIO LED LS INTERN 0 off off off off 1 on off off off 2 on on off off 3 on on on off 4 on on on on Table 1 Now the user can specify the new logical radio number by setting the LEDs with the corresponding buttons on or off. It is insignificant which LEDs are switched, or in what order this happens. Only the number of LEDs lucent is relevant as input for the new radio system number. Examples for valid input of radio system number 2: logical radio number LED REGISTER LED HIGH POWER LED PRIO LED LS INTERN 2 on on off off 2 off off on on 2 off on off on 2 off on on off Five seconds after pressing any button the configuration mode is finished. This is indicated by blinking two times of all 4 LEDs (REGISTER + HIGH POWER + PRIO + LS INTERN). The new radio system number is now saved will be used until this setting is changed again. Also the primary status of the LEDs and the function of the buttons are restored. The new settings are immediately effective; there is no need to switch DSpark on and off. If no changes are made in configuration modus the current setting persists when leaving the configuration. Therefore this procedure can be used to show the current setting of the radio system number. factory default
Multi room operation 28 Adjusting DMic/DDoc combination to a room (0 – 4) Please make sure only one DSpark in your venue has activated the register function (register open – LED OFF). Please make sure that the preset of the several DSpark Radio Transceiver Units is like described above. Open Register (LED OFF) on your first DSpark (Local radio channel number 0). Make sure other DSpark have their Register closed (LED on). Place the desired number of units on the table and press the MIC button one after each other. Resetting of DDoc Docking Units DSpark can reset all docking stations DDoc which are allocated to this DSpark (Radio Transceiver Unit) and are in operating distance. Therefore press the inner buttons HIGH POWER and PRIO simultaneously for about 5 seconds. The LEDs of HIGH POWER and PRIO are flashing for the time of deleting, but minimum three times. If you do this, all DDoc units will forget the room number they were tied to. This requires a new setup. Allocation of DDoc Docking Units To configure the DDoc units press and hold the MIC button for at least 4 seconds. This procedure is indicated by flashing of the multi MIC-LED. The current radio channel number is reset. In this mode DDoc searches for any DSpark Radio Transceiver Units. If one is recognized DDoc tries to log in. When successful DDoc gets confirmation and stores the new radio channel number as default. This will finish the configuration mode. If there is no log-in possible DDoc will terminate the configuration mode after 30 seconds and then switch off.
