This displays, at a glance, the current frequency selection and modulation parameters. The
top line also displays the lock status of the individual RF and ASI inputs (√ = locked) and the
video format detected by the decoder. The bottom line displays the currently selected
Decoder and Demodulator Modes.
Pressing the MENU key will take the operator to the main setup menus; pressing MENU
again at any point returns to this display.
Allows the operator to select the required Modulation scheme being used (LMS-T or
DVB-T).
NOTE: When the unit is first switched on, and when switching modulation modes, the unit
performs a self-test routine on the RF front end. This causes a slight delay (15-30s)
before the demodulator will lock. See Section 6.1 for more details.
You can turn Individual inputs on and off as required.
NOTE: In Dual Pedestal LMS-T mode, only Inputs 1 & 2 are active.
You can configure Frequency, Bandwidth, Guard Interval and Polarity. Apart from
Frequency, all have ‘Auto’ modes, which allows the Demodulator to detect the correct
configuration from the received signal.
NOTE: In Dual LMS-T mode, the bandwidth shown is the combined width of the two
pedestals.
If you are using a frequency outside the range of the currently selected downconverter,
then an ‘Invalid Frequency’ alarm will occur, and reception will not be possible.
For each RF input, select the downconverter type, and turn on power to the
downconverter. All current Vislink downconverters are listed, or the Local Oscillator (LO)
frequency of any unlisted downconverter may be entered by selecting OTHER. To enter the
incoming UHF frequency directly, select NONE. When NONE is selected, downconverter
power is disabled.
To change all RF inputs to the same downconverter settings at the same time, SET ALL
INPUTS should be set to ON; to set them individually, turn this setting OFF.
