The optimum RF input levels for the COM24 cards are -25 to -55 dBm per transponder.
COM24FLX cards can only be connected to a SWM module, they will not support a
multiswitch.
The RF connections from the COM24FLX to the SWM module MUST be as shown in
Figure 10 or some channels will not be received properly. Cards in slots 1, 4, 7, and 10
MUST be on separate SWM outputs.
Normal operational behavior of the COM200 chassis is achieved in ambient
environments of 95°F (35°C) or less.
The system will not be capable of streaming any video on any channel besides 100 until
the COM24 cards have been authorized by DIRECTV.
4.2.2 System Integrator Guidelines
The system integrator must provide a mapping of TV channels to COM24 slots and
tuners.
The COM1000 will generally be preconfigured, including the appropriate RF and IP
connections to an edge QAM device, which most likely is the QAM24.
A COM120 RF Distribution panel, consisting of DIRECTV-approved multiswitches and
K
a
B band converters, or a DirecTV SWM-32 unit, shall be supplied by the System
Integrator.
4.2.3 System Operator Guidelines
It is recommended to use the StarRoute SRSN4 Normalizer within the property‟s RF
plant before the COM120 RF distribution panel in order to normalize the B band K
a
signals with the traditional K
u
satellite signal levels. B band signals are generally higher-
powered and tend to saturate the converters unless the installer is very careful regarding
input signal levels going into the COM120 panel.
The operator must take care not to block the front and rear air passageways of the
COM200 chassis. Racks containing doors and/or rear panels are not recommended.
