QAM SYMRATE: OUTPUT FORMAT: OUTPUT CHANMAP: To make a change in the displayed parameter and its setting and if this is the initial setup, you will want to enter the `adjust' mode. To do this, press the ENTER button that is located in the center of the four arrow buttons and hold in for several seconds until the display begins to flash. After you are in the adjust mode (bottom line of screen flashing) use the left and right arrows to navigate among screens and use the up and down arrows to change the parameter setting. When ENTER is pressed, the new settings will be loaded and stored and the unit will exit the `adjust' mode. You may wish to not press ENTER until you have gone through all screens and settings and then press ENTER to save and load all changes in one step OR you can store just one or several parameters at a time and reenter adjust mode to set the next. UNIT ID: Parameter Setting Choices Second display line. Must be in adjust mode to change using up/down arrows. # (0 thru 63) OUTPUT CHANNEL: RF LEVEL: UNIT ID: Select the desired unit identification number when connecting the 'RS232 IN' connector to a PC or modem for remote control using 'Drake Remote Control Software'. If zero (0) is selected, the PC will ignore the unit. RS232 BAUD RATE: This setting determines the baud rate at which the MQM6000L communicates with the remote PC. Settings available are 2400, 4800, 9600 and 19, 200. All units 'daisy chained' to the remote PC or modem must be set to the same baud rate. MPEG PROGRAMS: This menu provides selections to determine which programs are multiplexed to form the new multiprogram transport stream output that will be supplied to the QAM modulator section. Choose the DEFAULT setting to multiplex the lowest numbered (or only) MPEG program from each of the six ASI inputs. Choose the SELECT PROGRAMS setting to allow the operator to pick which program (or no program) from each of the six ASI inputs is to be included in the output multiplex. Only one program from each of the six inputs can be selected. This selection must be made using a PC connected to the RS232 IN port and running the 'Drake Digital Headend Remote Control Software' program. It is the operator's responsibility to be sure that the total data rate of these programs does not exceed the maximum data rate for the output QAM mode that will be used. If the total input rate is too large, some programs will have to be dropped from the multiplex. RS232 BAUDRATE: 2400 4800 9600 19, 200 MPEG PROGRAMS: DEFAULT SELECT PROGRAMS QAM MODE: QAM-16A QAM-32A QAM-64A QAM-128A QAM-256A QAM-512A QAM-1024A QAM-64B QAM-256B QAM-1024B GRAY ENCODING: (This menu item only appears if QAM modes QAM-16A thru QAM1024A are selected. ) DVB DAVIC Setup and Programming, (cont) / Operation QAM MODE: This menu allows the user to set the modulation type for the output. Choices range from QAM-16A through QAM-1024B. 'A' suffixes indicate DVB compliant FEC and the B suffixes indicate DigiCipher II FEC encoding. Note that the output QAM mode usually must be QAM-256.
