3.5 INSTALLATION
The MOD-HDMI-Q can be programmed with one of the following ways:
• Fromthefrontpaneldisplay
• FromtheUSBinterface
3.3.1 Installation using the Front panel display:
The user is able to install very quick and easy multiple MOD-HDMI-Qs using the SSD
+ Button interface of the front panel of the device, following the steps below:
STEP 1:
Power up the MOD-HDMI-Q by adding the external power supply. The MOD-HDMI-Q
will need 40-50secs to initialize itself. The SSD (Seven Segment Display – No 2 / Figure
No1 ) depicts the initialization status.
STEP 2:
Choose a modulator by pressing the MOD Select button (No 5 / Figure No.1). The LED
display will turn on depending on the modulator that is selected.
Step 3:
Choose “Channel mode” by pressing the Channel/Prole button (No 1 / Figure No.1 )
The “Channel LED” will lit indicating that “Channel” selection mode is selected.
Step 4:
Choose “Attenuation mode” by pressing the Channel/Prole button (No 1 / Figure
No.1 ) The “Attenuation LED” will lit indicating that “Attenuation” selection mode is
selected.
Step 5:
Choose “Prole mode” by pressing the Channel/Prole button (No 1 / Figure No.1 )
The “Prole LED” will lit indicating that “Prole” selection mode is selected.
Step 6:
Repeat the procedure from step Νο 2 up to step Νο 5 for the rest of the modulators
of the MOD-HDMI-Q.
HOW PROFILES WORKS
In an installation all the modulators (or Mux in general) need to have dierent values of
the following elds to avoid conicts in the automated scan of the TV sets:
Program Name Service ID TS ID
For that reason, the user must always selects a dierent Prole number in every modulator
starting from Number #1.

HELPLINE 0861 40 41 42 • www.spacetv.co.za
MOD-HDMI-Q : Operation Manual 1v0
Eg. Let’s say we want to install three modulators in a CATV network. In step No 4 we will
choose:
• Prole No 1 for the 1st modulator
o meaning: Program Name = DTV 1
o meaning: Service ID = 1
o meaning: TS ID = 2240
• Prole No 2 for the 2nd modulator
o meaning: Program Name = DTV 2
o meaning: Service ID = 2
o meaning: TS ID = 2241
• Prole No 3 for the 3rd modulator
o meaning: Program Name = DTV 3
o meaning: Service ID = 3
o meaning: TS ID = 2242
As a result, all the above modulators have dierent values in the above elds.
Caution!!!
• Every time we choose a dierent Prole number, the MOD-HDMI-Q will apply a full
reset to itself that will last for 40-50 seconds.
• Using the USB interface, we have the ability to add custom values to the above elds.
3.3.2 Installation using the USB interface:
The MOD-HDMI-Q provides a USB interface with the appropriate software for advanced
programming.
System requirements
• Windows XP (SP1 or higher)

3.10 LCN Provider - Set the LCN provider
* TS ID must always be dierent between DVB-T modulators in the same network.
Caution!!!
• Modulation settings must be applied with care and in order to have adequate
output bitrate. The output bitrate (which can be calculated from the tables in
Appendix B) must be equal or greater than the total sum of the bitrate of the
encoders.
Example: Assuming we select the following modulation settings:
Modulation: 8K
Constellation: 16-QAM
Code Rate: 5/6
Guard Interval: 1/32
Bandwidth: 8MHz
• We have an output bitrate of 20.107 Mbps according to Appendix B.
• This means that encoder’s bitrate must be adjusted in such a way that the
total bitrate of the encoder does not exceed the 20.107MBps limit, otherwise
artifacts may occur.
• For example, one valid selection in case of four encoders would be to set each
encoder bitrate to 5Mbps since: 4 x 5Μbps = 20Mbps < 20.107MBps
