[. . . ] MQM6000L Multiplexing QAM Modulator Instruction Manual MQM6000L Multiplexing QAM Modulator QAM OUTPUT 0. 020 Mbits/S ENTER TM is a trademark of R. L. Drake LLC P/N: 3852505-B-2009 Printed in U. S. A. 2 Caution Statements WARNING: TO PREVENT FIRE OR ELECTRICAL SHOCK DO NOT EXPOSE TO RAIN OR MOISTURE A product and cart combination should be moved with care. Quick stops, excessive force and uneven surfaces may cause the product and cart combination to overturn. The lightning flash with arrow head symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] If the unit is not in the adjust mode, pressing the up button will display the firmware version number or pressing the down button will display the output QAM symbol rate. Rear Panel Connections 7 R1 R2 R3 R4 R5 RF OUTPUT ASI INPUTS AC POWER 120 VAC 60 Hz 15 WATTS IN OUT RS232 1 2 3 4 5 6 R1, RF OUTPUT ­ This type "F" connector is the high level (+40 dBmV), 54 to 1002 MHz, output from the MQM6000L upconverter section. R2, ASI INPUTS 1 through 6 - These six BNC type connectors each accept multiprogram ASI format MPEG2 transport stream inputs. R3, RS232 IN - Connection to a PC or modem for use with remote control / monitoring program or for firmware download. R4, RS232 OUT - Loop to another MQM or DQT. R5, AC Line Cord ­ For connection to the nominal 120 VAC power source. This unit is designed for use in countries with 120 VAC power standards but the power supply will accept an input voltage range of 90 VAC minimum to 260 VAC maximum with a power line frequency of either 50 or 60 Hz. The maximum power consumption is 15 watts. 8 Setup and Programming QAM SYMRATE: PRESET MANUAL x. xxxx MSym/Sec (only in manual) NORMAL CW STANDBY PRBS 15 PRBS 15M PRBS 24 PRBS 23M BROADCAST CATV IRC HRC 2 thru 69 (broadcast) 2 thru 158 (CATV) 1 thru 158 (IRC & HRC) xx. x dBmV (+30 to +42 dBmV) Programming and viewing of the various setup and operating parameters is accomplished using the front panel back lit, two line, sixteen character wide LCD along with the 4 arrow buttons and the ENTER button. The name of the parameter is on the top line of the display and the setting value is on the bottom line. To observe a certain parameter setting without intending to change its value, just use the left and right arrow buttons to navigate through the menus shown in the list. The current setting for each parameter is shown on the bottom line of the display. Note that depending upon certain settings, some screens are not needed and will be skipped. 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. # (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'. RS232 BAUD RATE: This setting determines the baud rate at which the MQM6000L communicates with the remote PC. 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. 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. [. . . ] The unit must be sent to the following address: Service Department R. L. Be sure to include your street address which will be needed for UPS return. UPS Surface (Brown Label) takes 7-10 days to reach us depending on your location, Blue takes 2-3 days. Red is an overnight service.
