Product Description
Product Name:17x17x8 subscribers cascade multiswitch for distribution of 16 SAT IF signals including terrestrial for up to 8 users
17x17x8 subscribers cascade multiswitch with an external power supply are designed for the distribution of terrestrial and satellite signals from 4 satellite positions for up to 8 subscribers. Cascade Multiswitches are compatible with all satellite receivers, which support DiSEqC control system. They are suitable for both analog and digital reception.
The multiswitches and external power suppies are designed for maximum efficiency in full operation, eliminating need for stand-by mode functionality.
Key feature:
16 satellite IF 1 terrestrial TV inputs to 17+8 outputs for satellite receivers.
Allow use of 4 Quatro or up to 8 Dual or Twin LNBs.
Single coaxial cable conveys both satellite and terrestrial signal.
External Switching Power Supply can set up the operational power of LNB.
Sheet metal housing with plastic holder.
All users can view all channels select satellite signal by analogue commands 13V/18V.
0/22kHz tone or DiSEqC2.0\DiSEqC1.0 and Tone Burst signal provided by receivers.
Very low tap lossMinimum through loss.
Specification:

The production process of 17 series cascade multiswitch:





Application diagram of 17in 17out 8 subscribers cascade multiswitch:

- Multiswitches are controlled by receiver by analog and DiSEqC commands. In receiver's configuration menu set LNB type to Universal and differentiate received satellites by parameter DiSEqC 1/2/3/4 (A/B/C/D)
- Multiswitches are not compatible with Monoblock LNBs
- If higher than available number of user outputs is required, simply use two multiswitches instead of one, routing LNB outputs via signalsplitters
- Terminate all unused outputs by 75 ohm loads, if terrestrial band is used
- Switching between active and passive processing of terrestrial band is possible by turning the attenuator at terrestrial input fully counterclockwise
- 22 kHz tone required for Quad LNB can be disabled by DIP-switch
- DC supply for preamplifier of terr. antenna is limited to 150 mA max. The supply is disconnected if higher load or short circuit is applied to terrestrial input. To keep power consumption at minimum level is however recommended to include external DC block if short-circuit conditions should persist on terrestrial input



BMS-9xx and BMS-17xx multiswitches have a built-in 22 kHz generator which makes possi-ble to send, through the miniature switchs on the unit, the command "22kHz" to selected SAT inputs, for High Band continuously.
• Active and passive mode of terrestrial band can be selected by the switchs or potentiome-ter. The return path is available in the passivemode.The applicable European Standards and national requirements to ensure electrical security have to be obeyed. Likewise natio-nal standards and requirements for radio
and TV receiving installations.
