Use of the DMM 4650 The DMM 4650 can be used in both, incorporated in a rack shelf system or as stand-alone unit. The installer should automate the daily sequences by external control keys, sensors, contact s and the corresponding unit settings. This applies for gongs, alarms, messages and their combinatio ns, as well as for recordings of variable [...]

Each of the 4 ports also supplies a power source in order to facilitate the connection of floating contacts. The ground and earthing conditions are shown in the above diagram. The strict separation of control and audio signals guarantees the trouble-free installation. Sequence function The following example shows in sequence the necessary steps fro[...]

OPERATING THE DMM 4650 General All adjustments carried out at the appliance remain in memory even if the appliance is not connected to a power source (EPROM). Pressing the EXIT-key lets you step back and forth through the levels of the operation menu tree (page 11). The stand-by mode is entered by pressing the EXIT-key when in the “main menu” .[...]

MESSAGE General: Messages are audio signals, stored in the DMM 4650 as information, alarm announcements or other often used texts. Recording a message can be performed directly at the DMM 4650 or by means of rem ote recording. Playback via sum output is achieved by starting a message (Mxx) within a suitabl e sequence (see “Trigger”, “Sequence[...]

Soft key “edt” Using the “edt” key in playback mode provides the opportunity to edit and manage your message structure . The keys are used to select the following menu items. Title Confirming “Title” with the soft key “ok” the selected message’s current name appears on the display. Using the cursor keys lets you enter a name which[...]

Recording level An integrated, electronic control automatically adjusts the input sensitivity of the DM M 4650’s (Mic, Line, Rec. Inp) inputs. This level setting remains unchanged, until the question “Select new recording level?” is answered by using the soft key “y=yes” before starting a new recording. By using a short test signal marks [...]

GONG General: Gong Presets are audio signals that can be started within a sequence. Order and parameters of a gong sequence can be edited. For test purposes the sound can be started in the “gong > editor” menu by use of the PLAY/STOP keys. It is audible via the Pre-Listen outputs. Gong Presets 20 freely programmable presets (user preset) are[...]

List of available gong parameters Type four-stroke, three-stroke bar1: first gong stroke, A highest sound, B, C, to D deepest sound attack1: attack rate from 00ms (hard) to 99ms (soft) release1: fading sound from XXL (long, several seconds.), XL, L, M, S, XS, XXS (short, approx. 1sec) start 2: start delay of the second gong stroke in seconds. (min [...]

ALARM General: Alarms are audio signals that can be started within a sequence. The alarms are square wave form s providing the possibility for various parameters to be adjusted. For test purposes, it is possible to start the alarms signals in the “alarm editor” menu using the PLAY/STOP key. They are present on the pre-listen outputs. Alarm Pres[...]

Announcement General: Using the announcement function provides the possibility to assign incoming audio signa ls from the recording inputs (Mic, line, Rec-Inp) directly to the sum output. Especially in stand-alone applications this option is particularly useful, since it will possibly save one microphone amplifier. Starting the function is either p[...]

Trigger General The menu trigger allows to assign the connection of a control input to a function of the D MM 4650 (sequence start) while various control inputs can initiate a single sequence. The separat e logic control settings for each input provide the possibility to optimally match the requirements of an installation. Pressing the soft key “[...]

Trigger recognition The level of the control inputs are periodically monitored by the processor. The sampling t ime (T s = sample rate) is typically T s typ = 30 msec. The maximum monitor interval can be set to T s max = 100 msec. Thus, shorter impulses, spikes or quick AC voltages are recognized inaccurate or with a delay (undersampling). The bi-p[...]

SEQUENCES General: Sequences are a series of single steps, determining the functions of the DMM 4650 step by s tep. Thus, providing the possibility to define signal sequences, volume levels, trigger outputs, time sequences, loops, etc. Triggering an input ( “trigger”) normally starts a sequence. However, for test purposes it is possible to star[...]

Title Confirming “title” with the soft key “ok” , the name of the currently loaded sequence appears on the display. Using the cursor keys offers the possibility to enter a name of maximally 8 characters. The soft keys “A-a” and “spc” shift between the upper and the lower character case or enter a blank character, respecti vely. Afte[...]

System setup General Basic functions are defined in the menu system setup. Examples are: behaviour during stand- by, language, data backup, etc. The factory defaults are explained in the table on page 36. Modif ications are automatically saved and remain in memory even without supply voltage. Operation menu system setup Confirming the menu selectio[...]

Sum level Confirming “sum level” with the soft key “ok” , enables the setting of the digital audio control “SUM” (see audio functions). Using the cursor keys this value in “dB” -steps can be changed and is effective at the audio output in stand-by mode (no sequence running); presuming that the bypass relay is off. A currently runnin[...]

The soft key “send” starts the data output via the REMOTE/RS232 connector. This menu item is meant for data transfers into a computer. This function can also be execute d via command at the RS232 interface[...]

Self test General In stand-by mode the DMM 4650 runs a number of test routines in order to detect device faults at an early stage. Errors are indicated by the flashing of the green POWER LED. On fatal errors or on a higher occurence of errors, the flashing gets faster and the fault relay drops. At the same time the a udio input is connected directl[...]

CONNECTIONS CONTROL INPUTS AND CONTROL OUTPUTS PORTS A - D General: Operation see page 21 (PORTS C, D are optional) Each of the 4 ports (A, B, C, D) have 4 inputs and 4 outputs and a power source for supplying f loating control keys or contacts. The inputs and outputs are galvanic insulated from the DMM 4650 and the adjacent control l ines. Port A [...]

Outputs: Max. output current (relay contacts): 1A at 24VDC 0.5A 50VDC Installation example: Installation example with factory presets: see also “Factory preset sequences” page 36 - 44 INPUTS: All input signals must be applied longer than 200 msec. in order to be securely recognized . Modifying this default is possible in the menu “Trigger”.[...]

Audio inputs and outputs The XLR inputs and outputs are electronically balanced and wired according to the IEC 268 standards. If unbalanced XLR connection is desired, PIN1 and PIN3 have to be bridged using a jumper. Specifications are to be found in the appendix on page 53. If balanced, floating connection is necessary, the extension kit NR 90211 h[...]

Remote, RS 232 interface, data backup General Data backup should be performed prior to new installations and programming modificatio ns of the DMM 4650. This ensures that replacing an appliance for service purposes takes the least effort , immediately providing identical functions on the replacement unit. When setting-up systems with simil ar funct[...]

The Backing-up process runs with lowest priority and can be interrupted by other sequences at any time. If this is supposed to be avoided, interrupting sequences are blocked by entering the use r3 password (high priority). If the backup is expected to take very long (“backup message” ), start “System setup > Restore > ok” after enteri[...]

Terminal programs The utilized terminal software has to be configured for data transfers (send and receive) with a word length set to 8-Bit and no data conversion. Setting examples for the program “Terminal”, coming together with Windows 3.lx package: Start the terminal software, click the window ‘configuration’ ‘data transmission’, set[...]

FACTORY PRESETS The installed software v 1.2 provides pre-stored factory presets for sequences, alarms an d gongs. Also defined are basic settings (menu “System setup”) as well as input and output lines. For dire ct use of these presets, installation examples are to be found on page 31.
