Figure 7.1 Main Menu Structure
Under Inputs Menu, you can monitor and configure the parameters of the Tuner, and TS over IP
input (only when the TS/IP streaming board is installed and the board is set to
“IP In”, refer to
section 7.4.6 Optional Function)
7.2.1 Status
You can monitor the status of the inputs signals under the status menu.
- ASI Input:
locked or unlock indicate the status of the ASI input.
-Tuner Input:
when the QPSK/QAM/COFDM signal is locked by the tuner, the bit rate is
displayed on the bottom row of LCD.
-Ethernet:
this indicates the status of the transport stream over IP input. The bit rate is
displayed on the bottom row of the LCD, if IP input is valid (note this menu is showed only
when the TS/IP streaming board is installed and the board is set to
“IP In”, refer to section 7.4.6
Optional Function).
7.2.2 QPSK/COFDM/QAM/DVB-S2
The tuner setting menu is different and exclusive according to DVB-S/DVB-T/DVB-C/DVB-S2
tuner is equipped. To receive the QPSK/COFDM/QAM/DVB-S2 signal, the relative parameters
below must be set to appropriate values for the receiving antenna over which the device can
receive the signal.
QPSK
LNB Local Oscillator
(L.O.) Freq:
enter the frequency of the LNB in MHz
Satellite Freq:
edit the satellite down link frequency in MHz. The IF
frequency will be calculated automatically
Symbol Rate:
enter the QPSK symbol rate
LNB Voltage:
select the correct LNB voltage output of the F-
connector: Off, 13 V, 18 V
LNB 22KHz:
activate the LNB 22 kHz control signal to the LNB: On
or Off.
Note:
please contact the local satellite operator for the satellite frequency and symbol rate.
<A>
Normally, 13V switches the LNB to receive Vertical/Left hand polarization while 18V
receive Horizontal/Right hand.
<B>
Normally, 22KHz control signal switches the LNB to receive high band if any.
