MESSAGE General: Messages are audio signals, stored in the DMM 4650 as information, alarm announcements or other oftenused texts. Recording a message can be performed directly at the DMM 4650 or by means of remoterecording. Playback via sum output is achieved by starting a message (Mxx) within a sui...

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 k...

Recording level An integrated, electronic control automatically adjusts the input sensitivity of the DMM 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 recordin...

GONG General: Gong Presets are audio signals that can be started within a sequence. Order and parameters of a gongsequence 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 ...

ALARM General: Alarms are audio signals that can be started within a sequence. The alarms are square wave formsproviding the possibility for various parameters to be adjusted. For test purposes, it is possible to start thealarms signals in the “alarm editor” menu using the PLAY/STOP key. They are pr...

Announcement General: Using the announcement function provides the possibility to assign incoming audio signals from therecording inputs (Mic, line, Rec-Inp) directly to the sum output. Especially in stand-alone applications thisoption is particularly useful, since it will possibly save one micropho...

Trigger General The menu trigger allows to assign the connection of a control input to a function of the DMM 4650(sequence start) while various control inputs can initiate a single sequence. The separate logic controlsettings for each input provide the possibility to optimally match the requirements...

Trigger recognition The level of the control inputs are periodically monitored by the processor. The sampling time (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 ina...

SEQUENCES General: Sequences are a series of single steps, determining the functions of the DMM 4650 step by step. Thus,providing the possibility to define signal sequences, volume levels, trigger outputs, time sequences, loops,etc. Triggering an input ( “trigger”) normally starts a sequence. Howeve...

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 bl...

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. Modifications areautomatically saved and remain in memory even without supply voltage. Operation ...

Self test General In stand-by mode the DMM 4650 runs a number of test routines in order to detect device faults at an earlystage. Errors are indicated by the flashing of the green POWER LED. On fatal errors or on a higheroccurence of errors, the flashing gets faster and the fault relay drops. At the...

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 floatingcontrol keys or contacts.The inputs and outputs are galvanic insulated from the DMM ...

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 thisde...

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. Specificationsare to be found in the appendix on page 53. If balanced, floating conn...

Remote, RS 232 interface, data backup General Data backup should be performed prior to new installations and programming modifications of the DMM4650. This ensures that replacing an appliance for service purposes takes the least effort, immediatelyproviding identical functions on the replacement uni...

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 user3 password(high priority). If the backup is expected to take very long (“backup message” ), start “System s...

Terminal programs The utilized terminal software has to be configured for data transfers (send and receive) with a word lengthset 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 ‘co...

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