Description
Network PID
Displays the network PID to which the DCX3520e-M is tuned to receive network messages, in
hexadecimal.
Hunt Mode
The hunt mode includes Hunted, None, Round Robin (RR), Search (SRCH), Fixed Frequency (FIX), or
EMM Provider ID (EMM).
LKC
The last known carrier is the last valid OOB frequency displayed in MHz and ranges from 70 to 130
MHz, with the specific values of: 75.25, 104.20, 72.75, 92.25, 98.25, 107.25, 107.40, 110.25, 116.25,
and 103.75.
LKC will remain blank during hunting if a valid carrier has not been found, and will be populated
once a valid OOB is found.
Agile OOB Tuner Hunting
Manually select an OOB frequency by pressing the Menu button while in the OOB Status diagnostics
screen. To exit this mode, press the Menu button a second time, or press the Power button.
If the set-top is in the process of hunting for an OOB frequency, control of frequency selection is
suspended, i.e., it is not possible to press the Menu button on the OOB status screen and display MAN
FREQ when the set-top is hunting.
Summary of Manual Selection of the OOB Frequency
The manual override frequency capability is only displayed if the box is not currently hunting and the
operator presses the MENU key while OOB OSD diagnostics are displayed. The MAN Freq displays the
LKC and allows the operator to select (via scroll up/down) a specific frequency to check if a valid OOB is
on that specific frequency. The MAN Freq parameter is the OOB frequency selected in the frequency
selection mode and displayed in MHz, with the specific values of 75.25, 104.20, 72.75, 92.25, 98.25,
107.25, 107.40, 110.25, 116.25, and 103.75.
1.
When in the OOB Receiver Status Diagnostic, press the MENU button to enter the frequency
selection mode. The Front Panel displays the frequency of the last known carrier. The OSD displays
a new “MAN FREQ” line at the bottom of the screen, which indicates the last known carrier
frequency. At this point, if desired, the frequency change mode can be exited by pressing the MENU
key a second time.
2.
Use the UP/DOWN channel or cursor keys to scroll through all 10 frequencies until the desired new
OOB frequency is found. The new frequency selections appear on the Front Panel and on the MAN
FREQ line of the OSD. When the last known frequency is selected, a dot appears in the middle-
upper part of the Front Panel.
3.
When the desired new frequency has been selected, press the SELECT key to start the search. The
manual frequency search lasts up to 40 seconds. As the DCX3520e-M searches, the frequency being
searched for flashes on the Front Panel. On the OSD, the MAN FREQ line of text is cleared, the HUNT
MODE displays FIX to indicate a search on a fixed frequency, and the OOB FREQ field changes to the
frequency being searched for.
4.
If the frequency is found with the proper EMM Provider ID, then the Front Panel displays the normal
OOB receiver status. The OSD LKC field changes to display the new frequency.
5.
If after 40 seconds the frequency search is not successful, the product performs a warm reset.
