    In order to get a tidy installation of the modules you should follow the next advises: • Place the DT-802 at the left end of the sub-rack. • Place the DT-700 and / or DT-710 at the right end of the sub-rack.
  • Page 14 Figure 5.- Application example DTTV. The wiring must be done when the DT-802 module is off. You do not have to turn it on until ALL connecting work is done (on one hand control cables between the CPU and the modules and on the other hand, TS cables between modules).
  • Page 15 Figure 6.- Application example DTTV. The DT-802 has an electric current sensor that prevents it from starting up when it is not connected to any module. Therefore the control module will not be ON if at least one connection is made previously.

    CONTROL MODULE. DT-802 For an optimal use of the capabilities of the DTTV, it is advisable to use an universal LNB with independent outputs or an universal LNB with dual polarity (V/H) and dual band (L/H), both with a switchable splitter for satellite, in order to be able of distributing simultaneously signals in different bands and polarisations.

    Turn on your equipment through the switch, which is placed on the rear panel of the module ( Fig. 7 [11] ). After starting up, the DT-802 scans the modules connected to it in order to detect how many and what modules are and if there is any problem.

  • Page 20: Main Screen

    CONTROL MODULE. DT-802 The scanning process takes about ten seconds. After it, it displays on the screen a list of all the modules identified. If the process takes longer, maybe there is a problem with the wiring or the CPU.
  • Page 21 CONTROL MODULE. DT-802 The automatic position assignment does not have any practical effect. Each time you restart the DTTV, the control module will assign different positions to each module. If you do not like this way to assign, Then you can create and save your own assigment.

  • Page 37: Glossary Of Terms

    CONTROL MODULE. DT-802 6. GLOSSARY OF TERMS MODULATOR: In telecommunications, the modulation is the process of varying a periodic waveform, i.e. a tone, in order to use that signal to convey a message. Normally a high-frequency sinusoid waveform is used as carrier signal.
  • Page 38 CONTROL MODULE. DT-802 COFDM: Coded Orthogonal Frequency Division Multiplexing modulation system used in the radio and televisión systems. Unlike other systems that modulate in a single carrier frequency with a very high rate of symbols, COFDM modulates information in many carrier frequencies, where each one has a very low rate of symbols.
  • Page 39 CONTROL MODULE. DT-802 MER: It is the Modulation Error Rate. It is a measure that allows knowing how good a modulated digital signal is. It is the equivalent of the information provided by the signal/noise rate in the analog modulations.
  • Page 40 CONTROL MODULE. DT-802 FIRMWARE: Firmware is a term sometimes used to denote the fixed, usually rather small, programs that internally control various electronic devices. Typical examples range from end user products such as remote controls or calculators, via computer parts and devices like harddisks, keyboards, TFT screens or memory cards, all the way to scientific instrumentation and industrial robotics.
