Xpnr Field Default: 1
Note: This field is not available when the ASI In option in the Input field is
selected. The Xpnr field cannot be edited if LFreq in the Mode field is selected.
The Xpnr (transponder) field allows selection of an initial satellite transponder
number (range: 1 through 24) and can only be used if the Xpndr option in the Mode
field is selected. The Xpnr field cannot be edited if LFreq is selected in the Mode
field.
Press the
4
button until the cursor is at the Xpnr label. Then press the ENTER
button to move into the field. Press the

buttons to select the desired
transponder number. Since the associated transponder/frequency tables are stored
in the DSR-4550, scroll through the transponder numbers and notice that the
associated frequency (shown in the LFreq field to the right) automatically changes
with the selection (970-1430 MHz).
When the desired transponder selection is displayed, press the ENTER button to
confirm selection and move the cursor back up to the field label.
LFreq Field Default: 1430MHz
Note: This field is not available when the ASI In option in the Input field is
selected. The LFreq field cannot be edited if Xpndr in the Mode field is chosen.
Contact the programmer or network operator for details about the satellite,
transponder, and frequencies being used during installation.
The LFreq field defines the L-band frequency to which the unit tunes during
installation. If the LFreq option in the Mode field is selected, use this field to
directly tune the IRD to the required frequency.
Note: The transponder number (shown in the Xpnr field) continues to contain
dashes (--) since a transponder number is not required.
For non-C-band, use the LFreq option to enter the exact center frequency of a
carrier. The receiver tuner pulls from a large offset to capture the signal, but
long-term tracking is best if the user enters a precise carrier center frequency.
Press the
4
button until the cursor is at the LFreq label. Then press the ENTER
button to move into the field. Use the
4 
buttons to select the desired
frequency. Select a frequency from 950 MHz to 2150 MHz and press the ENTER
button to confirm a selection and move the cursor back up to the field label.
The DSR-4550 requires 30 to 60 seconds to download the network data. Afterward,
the user can view the Port menu for the active port to select the satellite name from
a list of available satellites (for more details, see "Port Menu" on page 22).
