6.2 DMM 4650 Interconnection
Interconnecting the DMM 4650 is established through control inputs and outputs on the DPM 4000 or on the DCS
400 monitoring system (DCS 408, DCS 409, DCS 412).
Every single sequence needs a control output for the start / stop command and a control input for the
transmission of the return signal. The control output starts the DMM 4650 sequence with a positive slope and
stops it with a negative slope. The return signal's control input reacts to the negative slope and activates the
macro "Message Stop". Additionally, in most cases a control input is needed for the DMM 4650 READY / FAULT
signal. The following cabling example offers a possibility for controlling three different sequences including fault
recognition. This is accomplished by utilizing Port A on the DMM 4650 and the 8 I/O control module (IN 5 - 8 and
OUT 5 - 8) of the DPM 4000.

Using an adapter cable (2 x RJ-45 to 25-pole D-Sub), the shown cabling is established with relative little effort.
For a larger amount of sequences, it is necessary to additionally utilize Ports B, C, and D on the DMM 4650.
Triggering the sequence start / stop is accomplished through additional control outputs on the DPM 4000 control
module (OUT 2 - 4) or via relay contacts on the DCS 408 respectively on the DCS 409 modules. The return signal
is present at the control inputs IN 1 - 4 of the DPM 4000 control module; additional control inputs can be provided
via DCS 412 modules.
For controlling a DMM 4650 sequence, first you have to assign the start / stop and return message lines in the
PROMATRIX Designer software. Afterwards, defining the audio signals in the window "External Audio Signals
DMM 4650" is possible (the window opens when double-clicking onto the DMM 4650 symbol), where start / stop
and return message lines are assigned to individual audio signals. When this is done, starting a DMM 4650
sequence from a paging console is already possible. Individual zones are assigned in the paging console dialog
(key-assignment).
Defining additional triggers and zones is possible for the case that different events than a paging station keystroke
(external triggers, timer) are used to start a DMM 4650 sequence. Displaying text on the LCD during the output of
a DMM 4650 sequence is possible as well.
Programming examples for interconnecting the DMM 4650 are provided in the file Demo99_2.pmx, which is
installed during the installation of the PROMATRIX Designer software within the following directory:
/promatrix/examples/.
