• Channel Tuning Sequence: Use the up and down arrow keys to select
either numeric order or frequency order for the channel tuning sequence.
• Build Channel Plan: Press the Enter key to begin the Build Channel
Plan sequence. This sequence allows the user to create a channel plan
by "learning" the channels on a cable system. Ensure that the SDA-5500
is connected to the cable system.
• Step 1: Enter a name for the new channel plan that will be built. Use
the alphanumeric keypad to enter a channel plan name. Press the OK
soft key when completed.
• Step 2: Select a fixed channel plan to use for building the new plan.
Use the up and down arrow keys to select a fixed channel plan to build
the new plan from. Press the OK soft key when completed.
• Step 3: Enter the frequency at which to stop searching for channels.
Press the Enter key followed by the OK soft key to set the stop
frequency.
• The SDA-5500 will sequence through all channels in the selected fixed
plan until the stop frequency is reached. This operation can be
terminated by pressing the Stop soft key. When completed, individual
channels contained in the newly built plan can be edited.
3. Press the ENTER key, and you will be prompted at the first step to
name the channel plan to be built. The name should be a logical one
that will be easy to remember. The location of the headend is usually a
good name for the channel plan. When the name is typed in, press the
ENTER key.
4. The next step is to choose a channel plan from the built-in list that
most closely resembles the plan of your system. Typically your system
channel plan will be a subset of the built-in plan. Cursor down to the
appropriate channel plan and press the ENTER key or the OK soft
key.
5. You then will be prompted to enter the highest frequency that you
would like to scan. Type in the frequency and press the ENTER key
followed by the OK soft key. The unit will scan for the presence of
channels. After the scan is finished, this phase of the channel plan
building process is complete. Press the Exit soft key to return to the
main CHANNEL PLAN menu.
Editing A Channel Plan
The next step is to edit the channel plan to characterize it for your particular
system. Fig. 14-6 shows the EDIT PARAMETERS screen.
