Operating the DSR-4550
Input Field Default: Port 1
Note: Unless changed, the DSR-4550 displays values for an L-band input on Port 1.
The Input field displays the input to which the receiver is currently tuned. It allows
manual selection of Port 1 through Port 8 for the L-band inputs or ASI input to the
DSR-4550.
To select the Input, press the
4
button until the cursor is at the Input label and
press the ENTER button. Press the

buttons to scroll through the options: Port
1 - 8 or ASI In. Press ENTER to confirm the selection and return to the top line of
the menu.
Note: If Port 1 through Port 8 is selected, then move to the Mode field, Xpnr field
or Lfreq field. These fields are not visible when ASI In is selected.
The following Caution screen prompts the user to confirm the selection.
Press any arrow button (
4
) to back out of making any changes. However,
to confirm the selection, press the ENTER button to set the port selection.
Mode Field Default: Xpndr
Note: This field is not available when the ASI In option in the Input field is
selected.
The Mode field allows selection of the frequency plan type for the satellite to
which the DSR-4550 is tuned.
Note: If the application is a North American C-band satellite, select the
transponder number in the Xpnr field. Otherwise, use the LFreq option and the
LFreq field. The LFreq option can be used for all satellites, including current
C-band, Ku-band, and future satellites where the frequency plans are unknown at
the time of receiver manufacture.
Press the
4
button until the cursor is on the Mode label. Then press the ENTER
button to move into the field. Press the

buttons to display the choices: Xpndr
or LFrq.
• If Xpndr is selected, choose a transponder in the Xpnr field. The frequency in
the LFreq field is set automatically based on internal transponder tables.
• If LFreq is selected, dashes (--) appear in the Xpnr field because the
transponder/frequency relationship is not known. Select a transponder
frequency from 950 to 2150 MHz in the LFreq field. At this point, a
transponder cannot be selected in the Xpnr field.
Press the ENTER button to confirm the selection.
