3.2. Connection
Audio connection recommendations
The console microphone, a cardioid electret condenser type, is mounted on a gooseneck
and is not removable. It is supplied with an "anti-pop" foam windshield.
Its audio output is balanced and sent through pins 5-6 of the remote devices bus connector
(Euroblock). There are two connection methods:
1. Using a twisted pair cable: if you use a CAT5 cable (4 twisted pairs) to connect the console
to MIMO88, you should use one of the twisted pair for audio transport. The connection to
the MIMO88 audio input will be made by linking free pins (5 and 6) of MIMO88 Euroblock
(REMOTE 1 or 2) with a piece of cable and the relevant audio input.
2. Using an independent balanced cable: in installations with long cable runs and a high level
of electromagnetic interference induced on the cable, CAT5 cable connection can present
problems and in these cases it is recommended to use an independent balanced shielded
cable for audio transport
If you connect 2 consoles on the same remote control bus line (i.e. to the same MIMO88
connector for remote devices, REMOTE 1 or 2), you must take into account that only one can
transport audio through a CAT5 cable twisted pair. For the second console, you must use an
independent balanced shielded cable, or a second CAT5 cable, directly connected to the MIMO88
audio input.
Overall, audio transport through the twisted pair of a CAT5 cable can be done with FTP cable
(not screened). However, it is highly recommended to use cable with a global screening for all pairs
(S/UTP type) and even more a cable with individual screening for each twisted pair (S/STP type).
The choice for a type of cable will logically depend on the electromagnetic noise level of the cables
environment (structured cabling plates, conduits, etc.) and therefore on the risk of this noise
induction in the microphone audio signal
Audio levels of the microphone signal sent from the MPAGE16 can be set in EclerNet Manager
application. It is highly recommended to use EclerNet Manager DSP processing to insert a high-
pass filter (around 150 Hz) in the input channel of the microphone signal, in order to remove a big
part of it low-frequency noise, induced and captured from the MPAGE16 physical environment.
4. OPERATION
4.1. Quick guide for paging
Roughly, procedure for paging with a MPAGE16 console is the following one:
1.
Visual inspection of availability / busy zones (LED indicators)
2. Paged zones selection, by clicking on their touch keys ("1" to "16")
3. Press and hold the PAGE key while performing the paging
4. PAGE key release
5. Press the CLEAR key if you want to cancel the last zones selection
However, this process and its results when paging depend on the PAGER module
programming made in the MIMO88 unit the relevant MPAGE16 console is connected to. This
programming is done with EclerNet Manager application. Check EclerNet Manager application
manual for more information.
The following sections describe the function of the various keys, LED indicators, and other
elements of the MPAGE16; this description is necessary for correct programming and operation of
the console
