REAR PANEL OF THE MX-100B MATRIX
In addition to the battery-sector
power supply
, in the rear panel we find:
- 1 main communication port:
- RS422/RS485
over 4 points terminal block.
- RS232
over SubD9 female plug-in.
- 1 SubD37
plug-in and 1 SubD44
plug-in (interconnecting of two Matrices to obtain a 16x16
Matrix).
- 4 telecommands
on terminal block, which permits for instance the starting up of the pre-
recorded messages of a digital lector (GD-26) (stopped: opened and started up: closed).
- 1 two-points plug-in
for the "day/night" attenuation command. One jumper on each input-
output card which permits to choose the wanted attenuation for output when the command is
activated (contact closed):
- 0dB (there is no attenuation).
- - 3 dB
- - 6 dB
The input-output card is pre-configured on -6 dB.
- 1 button "DEGRADE 1 "
(BY-PASS 1) to the manual by-pass mode (input 1 in general call). In
this by-pass mode, the Din plug-in " Input by-pass mode 2) " is not used.
- 1 Din plug-in " ENTREE DEGRADE 2 "
(BY-PASS 2 INPUT) to plug in the (external) input that
will be automatically connected to the 8 outputs in case of power supply default. The telecommand
of this input allows in addition to commute this input in general call.
- 1 "PROG." Button
for:
- When it is in use
reinitialize the password which by default is "1 2 3 4".
- When programming
reinitialize the default Configuration (see chapter "Geographical
priority"). For security reasons, the access to this button in the rear panel is protected (it is necessary
to introduce a gadget in the hole to operate with this button).
- 1 two-points plug-in that indicates a power supply default
(an opening between X and Y
indicates there is a default).
- 8 input-output blocks, each one composed by:
- 1 Din plug-in of input
.
- 1 Din plug-in of output
.
- 1 RJ45 plug-in (paging microphone MX-101
.
- 1 micro-line commuter
.
By-pass mode (BpM): In the BpM the warning lights of the front panel are not managed (non
significant).
