General Description MEQ1000A MULTIPLEXING HYBRID QAM MODULATOR QAM OUTPUT 0.000 Mbits/S GENERAL DESCRIPTION The R.L. Drake model MEQ1000A is a commercial grade hybrid QAM modulator. The MEQ1000A features plug-in input modules that include an ATSC/QAM tuner, an ASI input, an SDI/HD-SDI input, HDMI (non-HDCP), Composite input, Component input, and analog NTSC inputs; thus the description 'hybrid' is used to describe it.
Installation & Mounting / Front Panel Controls 7 INSTALLATION AND MOUNTING NOTES This equipment is designed to be installed in a standard 19” rack. A built in fan provides air movement through the unit. When connecting an incoming RF signal source to two DTD1000 modules, note that the antenna or CATV source must be connected to both the A and B input connectors. These inputs are kept separate in case the inputs need to come from different antennas or one antenna and one CATV source.
Rear Panel Connections R1 R2 R3 R4 R5 R6 R7 R8 R9 MEQ1000A - This illustration shows the rear of the MEQ1000A. The ASI connectors are type BNC female. The ASI input is used to input SCTE-18 data in ASI format for use with DTAs and in EAS daisy-chaining applications. R1; RF OUTPUT – This is the high level (61 dBmV), 54 to 1002 MHz, output from the MEQ1000A upconverter section.
Setup and Programming / Software Flow Chart 9 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 two LEFT and RIGHT SELECT buttons and the five LEFT, RIGHT, UP, DOWN and ENTER buttons. The name of the parameter is on the top line of the display and the setting value is on the bottom line.
Setup and Programming (Continued) This section provides additional details regarding the selectable items shown in the ‘adjust’ mode on the Software Flow Chart on page 8. Choose the SELECT PROGRAMS setting to allow the operator to pick which programs from the A and B inputs are to be included in the output multiplex.
Setup and Programming (Continued) 11 If INPUT B is selected, the B program is used and A filtered out. If INPUT A+B is chosen, then both are accepted if present. Note: It is OK to use this menu to set up desired program selections 'off line'. That is, with no actual input at the present time. Programs may be selected that may not currently be in the input stream but are desired at some future time.
Setup and Programming (Continued) / Operation INTERLEAVER: Sets the QAM modulator interleaver. Choose among the available selections based upon your system / set top box requirements. For typical 256-QAM. DigiCipher II CATV systems, I128, J1 is the most commonly used interleave setting but many other choices are available. This menu does not appear in the adjust mode if the QAM mode is A (DVB) as there is only one choice in the DVB standard.
Operating Instructions 13 (from Drake Digital Headend Control Program) Operating Instructions - From Drake Digital Headend Control Program 1) Confirm that all connections to the MEQ1000A and its installed encoder modules have been made as described previously. Connect a serial cable from the RS232 IN connector on the MEQ1000A to the serial port on the PC. (This discussion assumes that the Headend Control Program has already been installed on the PC as per the instructions supplied with the software.
DTA/EAS Considerations and Additional Information DTA and EAS (EMERGENCY ALERT SYSTEM) CONSIDERATIONS Any headend using DTAs or EAS (Emergency Alert System) that includes the MEQ1000A must be setup with one EH24A / EH244 / EH244-IP being the “Master” device and the MEQ1000A and all other additional Drake Headend Products (EH24A / EH244 / EH244-IP / other additional MEQ1000A) being “Slave” devices.
Additional Information (Continued) 15 STATUS DISPLAYS When the units are not in the adjust/program mode, status displays are shown. These vary by input module: DTD1000 Digital Tuner and Demodulator Module - shows DEMOD SNRs. ASII ASI Input Module - shows ASI data presence. Pushing the UP arrow button will cause the firmware version number to display.
