3.3.1 Installation using the Front panel display
The user is able to install very quick and easy multiple MV7480s using the SSD +
Button interface of the front panel of the device, following the steps below:
1st Step
Power up the MV7480 by adding the external power supply. The MV7480 will need
20-30 secs to initialize itself. The SSD (Seven Segment Display – No2 / Figure No.1)
depicts the initialization status.
2nd Step
Choose “Chanel mode” by pressing the Channel/Profile button (No 1 / Figure No.1)
and the “Channel LED” will lit.
3rd Step
Adjust the output power using the output 20dB attenuator.
4th Step
Choose “Profile mode” by pressing the Channel/Profile button (No 1 / Figure No.1)
and the “Profile LED” will lit.
How Profiles works
In an installation all the modulators (or Mux in general) need to have different va-
lues of the following fields to avoid conflicts in the automated scan of the TV sets:
Program Name Service ID TS ID
For that reason, the user must always selects a different Profile number in every
modulator starting from Number #1.
Eg. Let’s say we want to install three modulators in a CATV network. In step No 4
we will choose:
·
Profile
1
for the 1st modulator
- meaning: Program Name = DTV 1
- meaning: Service ID = 1
- meaning: TS ID = 221
0
· Profile 2 for the 2nd modulator
- meaning: Program Name = DTV 2
- meaning: Service ID =
2
- meaning: TS ID = 221 1
· Profile 3 for the 3rd modulator
- meaning: Program Name = DTV
3
- meaning: Service ID = 3
- meaning: TS ID = 221 2
