3.5 INSTALLATION
The MHD101 can be programmed with one of the following ways:
● From the front panel display
● From the USB interface
3.5.1 Installation using the Front panel display
The user is able to install very quick and easy multiple MHD101s using the SSD + Button interface of the front panel
of the device, following the steps below:
1
st
Step
Power up the MHD101 by adding the external power supply. The MHD101 will need 20-30 seconds to initialize itself.
The SSD (Seven Segment Display – No2/Figure 1.) depicts the initialization status.
2
nd
Step
Choose “
Channel mode
” by pressing the Channel/Profile button (No 1 / Figure 1. ) and the “Channel LED” will lit
indicating that “Channel” selection mode is selected.
3
rd
Step
Choose “
Attenuation mode
” by pressing the Channel/Profile button (No 1 / Figure No.1 ) the “Attenuation LED” will
lit indicating that “Attenuation” selection mode is selected.
4
th
Step
Choose “
Profile mode
” by pressing the Channel/Profile button (No 1 / Figure 1.) and the “Profile LED” will lit indicating
that “Profile” selection mode is selected.
How Profiles works
In an installation all the modulators (or Mux in general) need to have different values 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 Νο
1
for the
1
st
modulator
o meaning: Program Name = DTV
1
o meaning: Service ID =
1
o meaning: TS ID = 224
0
● Profile Νο
2
for the
2
nd
modulator
o meaning: Program Name = DTV
2
o meaning: Service ID =
2
o meaning: TS ID = 224
1
● Profile Νο
3
for the
3
rd
modulator
o meaning: Program Name = DTV
3
o meaning: Service ID =
3
o meaning: TS ID = 224
2
As a result, all the above modulators have different values in the above fields.
Caution!!!
● Every time we choose a different Profile number, the MHD101 will apply a full reset to itself that will last for 20-30
seconds.
● Using the USB interface, someone has the ability to add custom values to the above fields.
3.5.2 Installation using the USB interface
The MHD101 provides a USB interface with the appropriate software for advanced programming. For more information
