Cautions!
The receiver provides DC power (refer to Chapter 3, Operating the Equipment
Locally) via the active L-band input connector to drive an LNB (Low Noise Block
Down-Converter). Do not connect equipment other than an LNB to this connector.
Failure to do this may result in damage to the external equipment.
The F-type Connector is not suitable for repeated connection and disconnection.
When intended for use in this way, fit a sacrificial connector and connect to it.
6.2.3 Connector Details – IF Monitor Input (RX1290/HWO/DVBS2/IF/CONST)
Connect the IF Monitor input to a suitable IF frequency source e.g. a
satellite modulator. The input can be activated using Input Status
Menu (Menu 2).
This monitor input is designed to give error-free demodulation in the
presence of a wanted carrier only, for example when being fed
directly from a satellite modulator.
The specification for this connector is given in Annex B, Technical Specification.
