Connecting the unit

Consult the manual of your AudioControl 12.8 before connecting the DIPEX, use a
standard CAT5 cable to connect the DIPEX. Normally, the main unit (AudioControl

12.8) will also provide the necessary power to the DIPEX unit.

*When applying an unbalanced line level signal, connector 3 and 4(GND and SIG-)
must be shorted using a wire bridge ! Connect the ground from the unbalanced
source to GND AND SIG-, the + to SIG+. When nothing is connected to SIG-, there
will be no sound at all.

Instruction manualDIPEX

1. Trig: trigger input: connect your voltage free priority contact here

2. GND: ground connection for the voltage free priority contact

3. GND: ground connection for the analog line level signal

4. SIG-: line level signal negative input (balanced)*

5. SIG+: line level signal positive input (balanced)

6. Config/test button: push the button to install the DIPEX unit with the

AudioControl 12.8. By pushing the config/test button the first time, the unit
will receive an address from the main unit. After receiving an address, the
button also functions as a priority test switch

7. Power led: blue led lights up when the unit is powered

8. Status led: the led shows the status from the DIPEX unit: green color: the

unit is paging, priority is active. The incoming audio signal will pass through.
Orange color: paging is requested, or the chime is sounding (priority level
1 to 7). Red: paging is not allowed because a higher priority unit keeps the
paging line occupied. Out of the box, the DIPEX has highest priority and the
status led will never be red. When this led blinks, there is no connection to an
AudioControl 12.8, or the DIPEX unit has not received an address from the
AudioControl 12.8.

9. 24 VDC jack: connect an external DC power supply here if the master unit is

unable to supply the power for the required number of microphones. Consult
the manual of your AudioControl 12.8 for more details.

10. Output (link): RJ45 connector. Connect multiple DIPEX end DIMIC units in a

daisy chain. Output (link) and input are internally hardwired to each other.
Audiocontrol 12.8 can power a maximum of 8 devices.

11. Input: RJ45 connector: connect the DIPEX to the AudioControl 12.8 using a

standard CAT5 cable

12. Output level adjustment: turn the potentiometer to adjust the output level

DIGITAL PRIORITY / EMERGENCY EXTENDER

Using DIPEX for the first time

Default settings: out of the box, the DIPEX is set up as a priority 0 (highest)
priority/emergency extender, meant for paging line level signals from evacuation
systems, emergency message players, telephone or alarm systems etc. When the
priority switch is activated, the chime from the AudioControl 12.8 will not sound
(DIPEX priority level = 0 = highest). If you want to make the chime sound, you
must configure the DIPEX as a lower priority unit (1 to 7).

Connect the DIPEX to the Audiocontrol 12.8 main unit using a standard CAT5
cable. The status LED will blink (red and orange), and the power LED will light up,
indicating that the unit is powered. Wait for approx 10 seconds until the status
LED blinks orange/green. Now push the test/config (6) button on the DIPEX unit.
The DIPEX will now receive an address from the AudioControl 12.8 unit. The
status LED will dim, indicating that the unit has been successfully configured. Push
the test button once to check the functionality: the status LED will light up green,
indicating that the line level signal is passed through (priority = 0, no chime).

NOTE: when you configure the DIPEX unit with a priority level from 1 to 7, the
chime from the main unit will sound when enabled. Please consult the graphic
installer interface for details. When the chime sounds, the status LED will be
orange, indicating that the unit is waiting until the chime has finished sounding.
When the chime has finished sounding, the status LED will become green and the
audio signal will be passed through.

Instruction manualDIPEX

Attention!

DIPEX cannot function unless properly connected to an AudioControl 12.8!

When another DIPEX unit is added to the system, it will become a priority
0 unit by default. This may cause a conflict with the first DIPEX unit. In
such cases, configure the priority levels of the DIPEX units via the graphic
user interface program of the AudioControl 12.8.

Do not connect the DIPEX unit to a computer or other network via the
RJ45 connector. This will cause malfunctions and may cause damage to
your network, computer and/or DIPEX. A maximum of 8 DIPEX units, or a
mixture of 8 DIPEX and DIMIC units can be powered by the internal power
supply of the AudioControl 12.8. If more than 8 units are required, you
must use an external 24 VDC power supply. A dedicated power supply
connector is available on all units. Maximum current consumption per
DIPEX unit is approximately 75 mA.

Maximum CAT5 cable length is approximately 400 meters (one DIPEX unit
connected, theoretical value).
