Page 9: Section 3 - Installation & Power-Up
3.2 Installation The MUX-2A-QAM multiplexer is designed to be installed in a standard 19-inch (480 mm) rack (EIA 310-D, IEC 60297, and DIN 41494 SC48D). To install the encoder, secure its front panel to the rack by inserting four machine screws, with cup washers, through the four mounting holes in the front panel. -

SOME TV SETS WILL REQUIRE RE-SCANNING IN ORDER TO DISPLAY THE REVISED CHANNEL NUMBER ASSIGNMENTS. NOTE: The CVCT Mode allows the MUX-2A-QAM to set each virtual channel assignment as a one-part three-digit integer channel number (major) only for CATV applications (ie:“570”) compared to the ATSC broadcast two-part format having major and minor channels (ie:“17-3”). -

The MUX-2A-QAM default setting is “No”. When this mode is enabled (yes selected), major and minor channel numbers and names can be added or edited under the MUX Output / Program # ( Section 8.9) menu. The MUX-2A-QAM creates and maintains the CVCT (cable virtual channel table) and MGT (master guide table) in this mode. -

Instruction Manual Section 9 - Emergency Alert System (EAS) The MUX-2A-QAM EAS feature allows all program streams to be replaced by an EAS broadcast when activated. An ASI input is required for EAS. The ASI format must be a single stream standard definition program (typically <=5.5 Mbps data rate) with MPEG 2 or 4 audio/video encoding. -
Page 21: Section 10 - Frequently Asked Questions
QAM 256. Question: What happens when more than 12 input programs are presented to an input? Answer: The additional programs are not recognized by the MUX-2A-QAM and cannot be multiplexed to the QAM output. Question: What is the maximum number of multiplexed programs and the maximum output data rate? ... - Page 22 Frequently Asked Questions (continued) Question: What happens if a programmed, operational MUX-2A-QAM loses power? Answer: The unit has a non-volatile memory that stores all of unit settings so that it can resume normal operation after going through its reboot sequence. Currently, PIDs are not stored in non-volatile memory. Use the PID offset feature on inputs having the same program numbers as another input.

Page 23: Appendix A: Measuring The Qam Output Signal Level
MUX-2A-QAM Instruction Manual Appendix A: Measuring the QAM Output Signal Level To ensure that the QAM output power level indicated on the LCD screen is indeed accurate, you can also measure the true equivalent signal level for the QAM carrier using the CW (Carrier Wave) signal. The unit is capable of supplying the CW signal which simplifies the measurement process because the output level does not need to be adjusted for the bandwidth setting limitations of the spectrum analyzer. - Page 24 Limited Warranty Blonder Tongue Laboratories, Inc.
