Motorola DCH3200 Agile OOB Tuner Hunting, Field, Description, Emm Pid, Network, Hunt Mode

4 DIAGNOSTICS

Field	Description
EMM PID	Displays the packet identifier (PID) stream the DCH3200 tunes to for EMM data, in
	hexadecimal
Network	Displays the network PID to which the DCH3200 is tuned to receive network messages, in
PID	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

An OOB frequency can be selected manually 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. pressing Menu button on OOB status screen to display MAN FREQ is not available when the set-top is hunting.

Summary of Manual Selection of the OOB Frequency (OSD Frequency Override in Hunted Mode)

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 frequency of the last known carrier is displayed on the Front Panel. 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 will appear on the Front Panel and on the “MAN FREQ” line of the OSD. When the last known frequency is selected, a DOT will appear 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 will last up to 40 seconds. As the set-top searches, the frequency being searched for will flash on the Front Panel. On the OSD, the “MAN FREQ” line of text will be cleared, the “HUNT MODE” will display “FIX” to indicate a search on a fixed frequency, and the “OOB FREQ” field will change to the frequency being searched for.
