The current date and time is displayed until the back-end controller is powered up. The software release is momentarily displayed before the modulator enters the first status window. 4.3 Menu System – Description and Operation The PT 5780 DVB-T Modulator is equipped with different functions dependent on the purchased options. An operating menu chart, which reflects the structure of the menu system when all possible functions are installed and enabled, is provided in appendix A.. The menu system is designed as a “tree” structure, with a number of different “branches”. Each “branch” is made up of a “menu options”. The lowest “branch” contains a configurable menu option with a list of parameters to choose from. Note that additional configurable options are available via remote access/control. See Chapter 6.2.3. The menu system has two main functions:- 1. system status display - the display of various modulator configuration settings through “status windows” 2. system configuration - the ability to modify the modulator’s configuration settings through “configuration windows”. On start up the modulator always enters the system status menu. There are two ways to enter the configuration menu system; by pressing [EXECUTE] followed by the [RIGHT] arrow button the configuration system will be opened at the top level entry point and the user will be able to navigate freely between all the menus. Alternatively, the user can press [EXECUTE] twice to open the menu system at a sub menu relevant to the status menu parameters being displayed when the key-press sequence is initiated. When using this navigation method pressing the [UP] arrow key will recall the last status display. 4.3.1 Power Up The start-up process includes the following status windows: ---------------------------------------- PT5780 DVB-T Modulator PTV - Power-up - 2001-07-08, 3:07:33 ---------------------------------------- And later: ---------------------------------------- PT5780 DVB-T Modulator PTV Release X.X ............................ ----------------------------------------](https://usermanual.wiki/UBS-Axcera/LL50ATC.Pro-Televsion-Modulator-Manual/User-Guide-556836-Page-27.png)

The complete hierarchy is provided in the attached menu structure diagrams. All menu windows in the configuration menu system contain a four-digit number in the top right hand position. This number is known as the menu identification number and is useful for referencing purposes. The menu-structure has a maximum of four levels; hence the four-digit identification. See examples below. Examples of the top level of the configuration menu system are shown below in Examples A and B. The character string “DVB-T Modulator“ is always positioned on the left hand side of the display when in the top level of the configuration menu system. The available menu items are shown on the second line and may be scrolled through using the 33 and 8 buttons. The “current” menu option is always shown in capitalised format with flashing “< >” brackets. If more menu options are possible than the display allows, three (3) dots are shown in the lower right position.

In a few cases, the “current” parameter is automatically updated in the display window, e.g. the Clock. The lowest level of any particular “branch” of the menu system produces a window that displays the available parameter list, a configurable value or a non-configurable value. At this level the only information given in the upper right hand corner is the menu identification number. If a parameter list is obtained (see Example D), the “current” parameter is always the first item and is capitalised and surrounded by flashing square brackets. Example D ------------------------------------------- Signal, Input, Auto Substitute <2110>w58E [ON] off ------------------------------------------- If an editable value is accessed (see Example E) the current parameter value is shown in the bottom left hand side of the display. The last digit of the “current” parameter value flashes to indicate that this digit will be changed if the [UP] or [DOWN] keys are pressed. The other digits of the value can be edited by navigating to the digit using the [LEFT] or [RIGHT] keys. The valid range for the parameter is indicated in square brackets in the bottom right hand side of the display. Example E ---------------------------------------- Sig.Out.

By applying the [LEFT] , [RIGHT] , [UP] , [DOWN] keys as required (see attached Configuration Menu System diagram) it is possible to navigate to a number of sub menus: SFN TS Control (ID 1100) This menu, which is only available when the instrument is configured for SFN mode, allows the user to select if the transmission parameters (constellation, guard interval, code rate, hierarchy) are to be controlled via the MIP (default setting) or if the parameters are to be set manually. If the manual mode is selected it is the operators responsibility to ensure that the selected parameters correspond to the parameters applicable to the transport stream to be transmitted. If the manually selected parameters do not match those applicable to the applied transport stream transmission in SFN mode is not possible (output will be muted). MODE (ID 1200) This menu allows the user to select the COFDM parameters for the transmission. Sub menus are available for setting Hierarchy (if hierarchical option is installed), IFFT, Code rate constellation and guard interval. The mode menu cannot be accessed if SFN TS control is set to “ON”.](https://usermanual.wiki/UBS-Axcera/LL50ATC.Pro-Televsion-Modulator-Manual/User-Guide-556836-Page-36.png)
![PT 5780 DVB-T Modulator ProTelevision Technologies Operating Instructions Instruction Manual Revision 3.11 4-15 MFN/SFN (ID 1300) The menu allows selection of the network mode to be applied for the transmission; Multi Frequency Network – MFN or Single Frequency Network – SFN. Note: The menu is only accessible when the SFN option PT 8732 is installed. 4.3.4.4 SIGNAL Menu System (Menu ID 2000) The signal menu system (menu ID 2000) is accessed by pressing the [EXECUTE] button followed by the [RIGHT ARROW] button as described in paragraph 4.3.4.1. When the menu system is entered at menu TRANSMISSION use the [RIGHT ARROW] button to navigate to the SIGNAL menu. INPUT menu (ID 2100) This menu allows the user to select the input source(s) and to set the status of the auto substitution function. In the non-hierarchical configuration the input menu (ID 2120) allows the user to assign a primary input source and a secondary input source. The instrument offers as standard a choice between two input sources (ASI input “A” and ASI input “B” corresponding to the BNC input sockets located in the rear panel of the modulator). Additional input sources such as two more ASI inputs (input “C” and “D” ) or an SPI LVDS input are available as options (When installed the SPI LVDS input is identified as input “C”). For non-hierarchical applications the user will typically program input ”A” as the “primary” and input “B” as the “secondary” input source. Should the “primary” signal source fail in this configuration the instrument will automatically switch over to the “secondary” input if the Auto substitution function is set to “ON” (requires that a valid MPEG-2 transport stream is applied to the “secondary” input). For hierarchical applications the user will typically assign input “A” as primary source for the High Priority input (Menu ID 2120) and assign input “B” as primary source for the Low Priority input (menu ID 2130). If the option that provides two additional ASI inputs is installed (Input “C” and “D”) the user may choose to program Input C as secondary input source for the High Priority input (menu ID 2120) and to program Input D as secondary input source for the Low Priority input (menu ID 2120) if it desired to add redundancy by means of the Auto Substitution function. That is, when the auto substitute function is set to “ON” the unit will automatically switch to the secondary input source if the primary input source fails (requires that a valid MPEG-2 transport stream is applied to the “secondary” input). OUTPUT (ID 2000) This menu allows the user to set a range of parameters that affect the generated COFDM spectrum. Sub menus are available for setting (centre) frequency, bandwidth, level, sideband filter (window) function, spectrum polarity, and local transmission delay (SFN only). A sub menu (menu ID 2210) allows the user to set the output frequency. The IF version allows setting of the frequency in the range between 35-37MHz. The RF version covers the range from 30MHz to 1000MHz. Note: In case of the RF version (option PT 8715 installed) the IF output is fixed to 36MHz. The RF version allows furthermore the user to set the output frequency by channel number (menu ID 2220). The applicable channel raster is programmable via the channel set-up menu (menu ID 2230). The channel set-up menu offers selection between a](https://usermanual.wiki/UBS-Axcera/LL50ATC.Pro-Televsion-Modulator-Manual/User-Guide-556836-Page-37.png)
![Operating Instructions ProTelevision Technologies PT 5780 DVB-T Modulator Instruction Manual Revision 3.11 4-18 Reference input (ID 2600) This menu allows the user to select the 10MHz clock reference source and to configure parameters with respect to the 10MHz and 1PPS reference inputs. Sub menus are available for selecting 10MHz source (menu ID 2610), impedance for the 1PPS reference input (menu ID 2620), impedance for the 10MHz reference input (menu ID 2630), and trigger level for the 1pps input. The 10MHz reference source can be set to Internal, External or Auto. By auto mode the unit will synchronize to an external reference if available and automatically switch to the internal reference if no external reference is available (no alarm will be raised if the unit switches to internal reference). By external reference mode the unit will synchronize to an external 10MHz when available and switch to the internal reference if no external reference is available (an alarm will be raised if the unit in this mode needs to switch to internal reference due to absence of external reference). Note: for SFN mode external reference should be selected. 4.3.4.5 ALARM Menu System (Menu ID 3000) The alarm menu system (menu ID 3000) is accessed by pressing the [EXECUTE] button followed by the [RIGHT ARROW] button as described in paragraph 4.3.4.1. When the menu system is entered at menu TRANSMISSION use the [RIGHT ARROW] button to navigate to the Alarm menu. Define Alarm menu (ID 3100) This menu allows the user to program the desired response for each of the possible alarms that can be raised by the unit. For each type of alarm the user can choose to route the alarm to one or several of the following destinations: Alarm destination Description Mute When the Mute option for an alarm is set to “ON” the alarm will be routed to the mute control circuit. In this case the modulator output will mute whenever the alarm is active. Event Log When the Event Log option for an alarm is set to “ON” the alarm will be routed to the Event Log. In this case the time and date when the alarm is raised and the time and date when the alarm is lowered will be recorded in the event log together with the specific name of the alarm type. Relay 1 When the Relay 1 option for an alarm is set to “ON” the alarm will be routed to Alarm 1 relay control circuit. In this case the Alarm 1 relay contacts will be activated whenever the alarm is active. The red ALARM led located in the front panel will be on for the duration of the alarm. Relay 2 When the Relay 2 option for an alarm is set to “ON” the alarm will be routed to Alarm 2 relay control circuit. In this case the Alarm 2 relay contacts will be activated whenever the alarm is active. The red ALARM led located in the front panel will be on for the duration of the alarm.](https://usermanual.wiki/UBS-Axcera/LL50ATC.Pro-Televsion-Modulator-Manual/User-Guide-556836-Page-40.png)

![PT 5780 DVB-T Modulator ProTelevision Technologies Remote Interface Instruction Manual Revision 3.11 5-3 The instrument will always send the response data in capitals. Headers are not sent in the response messages, only the parameters. 5.2.4 Long and Short Form Program messages may be sent in either long or short form. ♦ The long form is the full word ♦ The short form is usually the first four characters of the long form The short form in a syntax specification is shown in upper case, and the remaining part of the long form is shown in lower case characters. Note: Upper and lower case, as used in syntax specification, is only a notation habit to facilitate distinction between long and short form. The instrument itself does not differentiate between upper and lower case characters. In program messages, either the long or short form may be used in any mix of upper or lower case characters. There is no semantic difference between upper and lower case in program messages. 5.2.5 Syntax Elements ; Semicolon separates two commands on a command line and does not change the path. : Colon separates the keywords of a command. In a command line, a colon “:” after a separating semicolon “;” indicates the root control level. Moves down for level. , Comma separates parameters. ?? Question mark identifies a query command. (Query commands are formed by adding a question mark to the header command). * Asterisk identifies a common command. (Common commands consists of a header command preceded by an asterisk and possibly followed by one or more parameters) ’ or ” Single or double quote introduces and terminates a character string. Space Space character separates the command header and parameters. | Parameters divided by a “|” indicates an “or” selection between the values shown. Only one value may be used at a time. [xxxx] Square brackets indicate an optional specific string parameter used by some command systems.](https://usermanual.wiki/UBS-Axcera/LL50ATC.Pro-Televsion-Modulator-Manual/User-Guide-556836-Page-57.png)
