SETTING UP HEADEND FILES - continued
To set up a different headend location, close any existing connection, then use the "Setup New
Headend" button again and repeat the above steps for the second location. Add as many
locations as needed using this same procedure.
NOTES
(1) Right click on a headend name to edit or delete that headend if needed.
(2) This software contains factory default SCT parameter settings including presets for
certain popular services. These may or may not be the same settings that are factory loaded
into the transcoders themselves. You may wish to first set all parameters in the PC file for your
specific headend without connecting to the headend. You may then download these PC settings
to the headend with one command. If you wish to do this, proceed to the Off-line Editing
section.
To begin connecting to a headend now, skip the following "Off-line Editing" paragraph and refer
to the "Connecting to a Headend" paragraph.
OFF-LINE EDITING OF TRANSCODER PARAMETERS
To edit parameters off-line, choose the "Continue without Connecting" option from the modem
connection menu or if a direct connection is programmed, proceed as usual and edit the
appropriate PC files. Do not download the PC files to the transcoder but be sure to save
changes when prompted for this response.
CONNECTING TO A HEADEND
From the R.L. Drake SCT Control Program main screen, proceed as follows:
■
Click to highlight a desired headend name and select that headend.
■
Click on the "OK" selection.
If a direct connection is being used, this will make the connection.
If the modem choice was selected, enter the phone number to be dialed, if not already present.
Click on the "Connect" button to make the connection.
■
Once connected, the screen will display eight sets of transcoder info at a time. To speed up
the display refresh cycle, remove check marks from all unused transcoder numbers for all
transcoder screens. Click on the appropriate button to display another set of 8 transcoders.
■
If no data can be received from the transcoders, check the RS232 baud rate setting (right
click on headend name or select "edit" from the file menu). The setting must match the
transcoder setting. If necessary, use the remote modem setup procedure to program the
remote modem for this same baud rate.

PASSWORD PROTECTION
It is always possible to connect to the SCT headends with the RS232 control software,
regardless of password settings. However, without a valid password, you will only be able to
view the existing settings and edit the PC files. It will not be possible to download any new
parameters to the transcoders. This prevents unauthorized tampering with the headend settings
via the RS232 link. With SCT860s, DQT861s, or MQM861s each unit is set individually. With the
18/28/38/4860 units, the password is set on the PS150/PS151 and applies to all 10
transcoders per supply.
The factory default password is 0. If this password is not changed and the RS232 control
program is also kept at the default 0 setting, full access will be permitted. If password
protection is desired, program a new password. To do this, there must be a person at the
headend to put each transcoder or supply into the password programming mode.
Start the password program process by connecting to the headend, either by direct connection
or via a modem. You can always connect regardless of the password settings. After connecting
to the headend and while viewing the eight transcoder summary screen,
■
Click on the "Change Password" button.
■
In the space provided on the "Change Password" screen, enter your desired new password.
Do not click the ‘OK’ button yet.
■
Now have the person at the headend place all SCT860s, all PS150/PS151s, all DQT861s,
and all MQM861s to receive the password in the loading password mode by pressing the left
arrow, enter, and right arrow buttons simultaneously. Hold these until the that unit's display is
displaying the "Loading Password" message. Repeat on each SCT860, DQT, MQM, or power
supply until all displays are showing the "Loading Password" message.
■
Back at the PC, click on "OK" to transfer the password to the transcoders. It is essential that
this order is followed. The new password is now set in both the PC software and at the
transcoders.
■
Test the new password by downloading a PC file to a transcoder.

EIGHT TRANSCODER SUMMARY SCREEN DISPLAY
Each summary screen displays four items of interest for each of eight transcoders: Mode,
satellite S/N, Output QAM symbol rate, and alarms or firmware version number. When the
View/Edit button is pushed for any one transcoder, the detailed parameter screen, showing a
full set of parameters, will be accessed.
DETAILED PARAMETER SCREEN
When the "View/Edit" button is selected, this screen provides all parameter values for the
selected transcoder as stored in the PC file on the left side and the actual operating param-
eters in the SCT will be shown on the right side. The parameters in the left side PC file may be
changed without affecting the actual hardware operation. When desired, values from the PC
file may be downloaded to the transcoder from the screen. Alternatively, you may wish to
select other transcoders and adjust values as desired in the PC files and then return to the
summary screen and download all of the PC files to multiple transcoders in one operation.
Many times it will be desirable to set up the entire set of headend parameters off-line and then
download all of these PC files to the multiple transcoders.
