TECHNINET is designed to convert satellite IF (Intermediate Frequency) signals into VHF­compatible signals (Version A:EO2...EO4, SO2...SO4, Version B:SO4...S10, EO5...E12,
S11...S20, Version C: E21...E37, S21...S41). The unit is fully programmable, compatible with
neighbouring channels, and converts stereo/dual tone signals in accordance with the dual
sound carrier protocol. In the VPS versions, an integrated line data decoder evaluates the
PDC/VPS data broadcast by many stations/providers. The units are thus in a position to re­cognise varying sound modes received from the broadcaster (mono, stereo, dual channel
sound), and to automatically activate the appropriate code frequencies within the PAL signal.
Channel 1 is supplied by a separate input, E1. An integrated distribution field is available at
input E2, which distributes the signals of one level to channels 2, 3 and 4. This signal is then
subject to damping by 9 dB before being made available for further distribution at output A.
Both Satellite-IF inputs are provided with current appropriate to an LNB (13V, 300 mA max.)
It is possible to loop an external decoder through into channel 4, using the Sub-D connector.
The appropriate connection cable for Sub-D-SCART is available under Order no. 0000/3613.
The output level of the individual channels can be adjusted by means of the respective con­trols (approx. 80..100 dBµV.
Data remains in memory even if there is a power failure.

Installation:

Please ensure there is enough space to provide adequate ventilation. In­stall the base station in a room in which a maximum ambient temperature
of 55° C. is not exceeded at any time, even at the height of summer.

Mount the unit(s) in an upright position next to each other on a wall surface, or use the wall­mounted housing, which is obtainable as an accessory. Ensure that units are placed

at a distance of at least 4 cm from each other.

Where several units are to be installed together, the relevant ouputs must be connected by
means of multiple connectors (or by means of inversely switched BK distributors). This will
result in a certain level of collective damping, which may make it necessary to include a sui­table BK amplifier in the signal path. However, amplifier output levels in excess of 110 dBµV
are not recommended.
The IF in-/outputs can be switched as required, depending on programme allocations. Pay
attention to the acceptable range of levels at the inputs.

NOTE:

In order to avoid damage to the TechniNet units, the installation should be
properly grounded (earthed) before it is switched on.

Preliminary Settings:

All four channels are preprogrammed to default settings at the factory, in order to provide a
defined starting point for the user. Pre-programming is carried out in relation to ASTRA, and
with reference to an LNB with a LOF of 9.75 GHz. The following settings are programmed at
the factory:

- audio bandwidth 130 kHz - video level high

- volume 0 dB - internal signal path (channel 4)

- adaptive de-emphasis - VPS versions: VPS auto on

- audio A 7.02 MHz, B 7.20 MHz - output offset 0 kHz

Programming block:

Programming is entered via the keyboard.In order to prevent an unintentional change in sto­red data, the keyboard is electronically blocked once programming has been completed.
This programming block can be idsabled by pressing both arrow keys simultaneously for ap­prox. 4 seconds. Once the red display starts to blink, you have approx. 3 seconds in which to
press both the "+" and "-" keys, which will enable the programming mode (display of channel

1)

Programming:

Switch on the current supply, and enable (unblock) the keyboard. The number of the channel
selected appears in the red display, the parameters selected appear in the green display.
The parameters are set by means of the "+" and "-" keys. The arrow keys are used to move
on to the next parameter. The "M" key is used to store the programmed values, and to move
on to the next channel.
When you have selected channel 4, pressing the "M" key will result in programmed values
being stored in memory, and you will exit the programming mode (red display shows "-").
The following parameters can be called up successively for each channel, and altered:
