Any field which is an R/W (read/write) can be and is stored in a configuration group.
A group is selected by choosing one of the 16 groups and then clicking on the LOAD
button. This action loads all R/W fields (under any of the TABs or pull down menus,
not just the MAIN PAGE TAB) with the stored values of that group.
A group can be changed by editing an R/W field and then clicking on the APPLY
button (“APPLY” also automatically saves). All R/W field values (under any of the
TABS or pull down menus, not just the MAIN PAGE TAB) are stored to the current
configuration group (the current selected group).
For example, current group 1 is selected and the existing RF FREQ is set at 2300 MHz. User
wants to change it to 2250 MHz. User changes RF FREQ field to 2250 and then clicks on
the APPLY button. New frequency is automatically saved to the current group 1.
2.6.4 Status Indicators
The Demod lock status indicates if the demodulators are successfully locked to the RF
signal.
The MPEG Decoder Lock Status is an indication that the Video Decoder is successfully
locked to the incoming digital bit stream.
Both indicators must be locked to decode the transport stream to display video. These
indicators can be very helpful in troubleshooting. For example let’s say the demod lock
status is locked and the OSD (on screen display) is reporting good SNR readings; however the
MPEG Decoder lock status is not locked. This could be an indication that video at the
transmitter end has problems (of course it could indicate other errors as well).
Scrambling Status indicates that incoming signal is scrambled.
2.6.5 BDC Set Up Button
This button on the main page tab is basically a shortcut to the BDC (block down converters)
setup page. It also can be found under the pull down Options Menu\System Setup\BDC. See
Table 3 for an explanation the fields.
Keep in mind you must click on the APPLY button in order for new values to take effect.
Warning: These values are pre-set at the factory for each configuration
group. If the values are changed they can prevent the digital link from working.
Ensure they are correct before changing.
