Connecting the unit
Consult the manual of your master unit before connecting the
microphone. Use a standard CAT5 cable to connect the microphone
to the main unit. Normally, the main unit will also provide the
necessary power to the microphone. Consult the manual of your
main unit for more details.
DIMIC12S, the slave unit, cannot be used without the DIMIC12
digital paging station. The purpose of the slave unit is to expand the
number of zones and/or programmable function keys on the paging
station. The slave unit is connected to the paging station using the
flat cable supplied with the slave unit. It is possible to daisy chain up
to 7 slave units.
The opening for the flat cable is at the right side of the DIMIC12
unit. Just pop off the small lid and connect the flat cable. Connect
the other end to the left side of the slave unit and so on…

Knobs 1 - 12 are for zone selection or programmable functions.
The amber LEDs next to the knobs will light up when the knobs are
pushed. The behavior of the LEDs and knobs depend on what has
been programmed in the master unit. The knobs can be configured
as latching or non-latching knobs, zone selection knobs, function
knobs or preset recall knobs.

Knobs 13 and 14 are the actual paging buttons: when pushing
knob 13, all pageable zones will be paged. When pushing knob 14,
all selected and pageable zones will be paged. The corresponding
selection LEDs will light up to confirm the selection.
The ready-busy LED is green when the unit is ready and when
paging is allowed. It turns orange when a paging request is sent
to the master unit and turns red when paging is forbidden due
to priority restrictions. During the time the chime is sounding, the
ready-busy LED will stay orange. When the chime has finished
playing, the LED will turn green to indicate that paging is possible.
The amber selection LEDs of the selected zones will flash during
paging.

1. Output level adjustment: turn the potmeter to adjust the
output level
2. Output link: RJ45 connector. Connect multiple DIMIC1/12(S)
units in a daisy chain. The maximum number of units depends
on the capabilities of the master unit. Output (link) and input
are internally hardwired to each other.
3. Input: RJ45 connector: connect the DIMIC12 to the master
unit using a standard CAT5 cable.
4. 24 VDC jack: connect an additional DC adapter here if the
master unit is unable to supply the power for the required
number of microphones. Consult the manual of your master
unit for more details.
Please note that the combination of multiple mics and excessive
CAT5 cable length will cause a substantial voltage drop on the
CAT5 cable. In case of doubt, use a DC adapter as power source for
the microphone/slave.

DIMIC1 has no zone selection knobs. Only the push-to-talk button
is present. Configuration and default functionality depends on the
master unit’s possibilities. Ready-busy has the same functions as
DIMIC12.

PAGING MICROPHONE
Using the DIMIC1/12(S) for the first time
Default settings: out of the box, the DIMIC12 is set up as a 4-zone
paging mic. Knobs 1 to 4 are configured as zone 1 to 4 selection
knobs. Knobs 5 – 12 have no function (yet) and must be configured
via the user interface of the master unit. The slave unit has no
default settings and must be configured before use. Knob 13,
marked “all zones”, functions as an all zone paging knob. Knob 14,
marked “selective” functions as a push-to-talk button.
LED messages: during power on, the DIMIC12(S) LEDs light up 5
times from bottom to top, left and right rows simultaneously, to
indicate that the unit is performing a diagnostic self-check.
When the LEDs light up going up and down, left and right rows in
opposite directions, the microphone is requesting an address from
the master unit.
Confirm the request by pressing the “all zones” or “selective”
button. The LEDs will stop blinking to indicate that the unit has
been accepted by the master unit. The address is permanently
stored in memory and can only be erased via the user interface of
the master unit.
The behavior of the 12 knobs can be configured in the user
interface of the master unit. It is possible to make the knobs work
as latching or non-latching knobs, or to assign a special function, a
preset containing preselected zones…
By default, the zone selection knobs work like this: when a zone is
selected, the corresponding LED will light up. When the selected
zone is being paged, the LED will blink. When paging is finished,
the LED will go out and the unit is ready for a new selection. You

Attention!
can also program the unit, so that the selected zone LEDs stay
lit after paging. Consult the manual of the master unit for more
details.
By using automated addressing, the master unit will recognize
the microphone/slave, and will automatically recall the settings
and functions of the push buttons after power up. When a new
microphone is added to the system, you must configure the newly
added microphone via the user interface of the main unit.
Do not connect a slave unit to the microphone unit when powered
on. The slave unit will not be recognized and will not function when
hot plugged!!!
When a communication error occurs between microphone and
master unit, or between microphone and slave unit, the LEDs of the
microphone/slave will start to scroll continuously from bottom to
top, left and right simultaneously, to indicate that communication
has failed. Check all connections as well as the cycle power of the
main unit and microphone/slave to restore normal functionality.
DIMIC1/12(S) cannot function unless properly connected to a
compatible master unit!
Do not connect the microphone to a computer or other network.
This will cause malfunctions and may cause damage to your
network and/or microphone. You must connect the microphone to
the master unit via the CAT5 cable.
