Under the Inputs heading, you may select the desired RF input video channels
for each of the four RF tuners. Select the Broadcast radio button for off-air
signals or the CATV radio button for cable television signals. Enter the chan-
nel number and click
Tune
.
Under Outputs , you may set the output data rate, PSIP presence (enabled or
disabled), and TSID for each ASI output. The output data rate may be selected
from the drop-down menu as 19.39 Mbps, 26.97 Mbps, 38.81 Mbps, or a cus-
tom rate from 2.5 Mbps to 100 Mbps in 1 kbps steps. To set a custom output
data rate, choose
Custom (2.5 - 100) from the drop-down menu and enter the
desired rate (in Mbps) in the box immediately below the menu.
Finally, under the Control heading, PID Display Mode allows selection of
either a decimal or hexadecimal numbering system for display of the PID
addresses on all screens.
Time Source is used to select which RF Input to use
for the STT signal to be included in the PSIP output of all four multiplexers.
Status
The Status section on the right side of the page provides the status of all input
and output signals. The status information is periodically updated automati-
cally. Received signal parameters are labeled
RF Input 1 through RF Input 4 .
These reports include channel selected, frequency, modulation type, frame lock
status (true or false), TSID, signal-to-noise ratio (SNR in dB), signal strength
quality, and errored seconds. Any active alarms or warnings are displayed in
red text beneath the status of the affected RF input.
ASI output information includes the output data rate, the TSID, and the occu-
pied bandwidth of each of the four ASI outputs (
ASI Output 1 through ASI
Output 4 ).
