User manual DRAKE DIGITAL SCT

[. . . ] SETTING UP A REMOTE MODEM If a pair of modems will be used to connect the PC to the headend via a dial up phone line, the following procedure must be followed. The remote modem that will be located at the headend equipment location must be set up for auto answer mode and it must also be set to communicate at the same baud rate as the transcoder settings. It is suggested that this not be changed unless your modem will not operate at this speed. When changing the RS232 baud rate, be sure to change it in three places: 1) the setting on the SCT/PS unit, set with front panel buttons. [. . . ] Up to 10 transcoders can be controlled with a single connection to one PS150 or PS151 (or up to 6 SCT860s with a PS100). When more than one tray of transcoders is installed, or when DQTs or MQMs are also present, the data connection can simply be looped through all associated PS100, PS150, and PS151 power supplies and the DQT861s and MQM861s to pick up all of the transcoders. The maximum number of SCT860s that can be controlled as one headend via a single RS232 connection is 63. The maximum number of SCT1860, SCT2860, SCT3860, SCT4860 transcoders is 70 per headend. Each headend file can contain its specific parameters, connection type, dial-up number, password, etc. The PC may be connected directly to the PS100, PS150, PS151, DQT861, or MQM861 RS232 input DB9 connector via a standard serial data cable. If the control and monitoring is to be from a remote site using a dial-up telephone line, modems may be used to make this connection. Here are the major issues to be addressed in order to set up your remote monitoring and control: s Assigning UNIT ID numbers. A FEW WORDS ABOUT UNIT ID NUMBERS In order to view settings or control a transcoder, it must be assigned a unique UNIT ID address in the desired headend. The SCT1860/2860/3860/4860 series of transcoders uses a system where the connected PS150 or PS151 is assigned a number from 1 to 7 and the 10 transcoders connected to that supply are automatically assigned a number between 1 and 10 determined by which socket they are connected to on the power supply. If the PS unit ID is set to 0, the transcoders connected to that supply will not be seen or addressed by the remote control software - control must be from the power supply panel. See the instruction manual 3 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. 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. 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. Drake SCT Control Program main screen, proceed as follows: s Click to highlight a desired headend name and select that headend. If the modem choice was selected, enter the phone number to be dialed, if not already present. [. . . ] 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. After connecting to the headend and while viewing the eight transcoder summary screen, s Click on the "Change Password" button. s In the space provided on the "Change Password" screen, enter your desired new password.
