BMS-1732K 19 Inch Multiswitch

Product Information: BMS-1732K 19” Multiswitch for 4x SAT + 1x
Terrestrial

The BMS-1732K is a multiswitch that enables the distribution of
satellite signals from four LNBs and one terrestrial input to up to
32 receiver outputs. The device features cascading loop-through for
SAT/IF inputs, tap-loss subscriber outputs, and a TERR gain of
23-25dB. It supports the selection of LNB/polarity 13V, 18V,
13V+22KHz, and 18V and has a frequency range of 950-2150MHz for
SAT/IF and 47-870MHz for TERR. The device has a return loss of
10dB/14dB for input/output and isolation of >33dB for SAT-SAT
and >37dB for SAT-TV.

The BMS-1732K has a compact design with dimensions of 320 x 320
x 90mm (2RU) and can be cascaded to a following unit to double or
even multiply the needed output numbers. The device supports quad
& quattro usable LNBs, and the maximum current from the
subscriber output is 41mA. The device also has a maximum current
from the system of 960mA and a maximum current with LNB of 920mA.
The operating temperature range is suitable for most indoor
installations.

Product Usage Instructions

We strongly recommend that the installation of the BMS-1732K be
carried out by technical professionals. All necessary connections
to the LNB’s SAT-A…D as well as the cascading outputs are printed
on the rear and front panel, so a mismatching usually cannot be
done. Please ensure that every component, including the BMS, Coax
cables, and antennas/dishes, is grounded to avoid voltage
differences between devices. The grounding should also be fit to
earth potential to secure them against lightning influences.

The BMS-1732K supports cascading to a following unit to double
or even multiply the needed output numbers. However, a cascading of
more than 7 units is not recommended due to the attenuations of
each. The cascade units should disable the power. The LNB-powering
can be switched OFF (default is = ON) by the front panel
switch.

For active terrestrial input and distribution to every output,
trunk lines (cascade outputs) should always be terminated with
75Ohm incl. DCBlocker. The device supports DiSEqC, and the
technician should have knowledge about it. Electronic equipment is
not household waste and must be disposed of properly at an
appropriate official collection point at the end of its service
life.

Quickstart

BMS-1732K

We strongly recommend the installation by technical skilled people.
All needed connection to the LNB’s SAT-A…D as well as the cascading outputs are printed to the rear and front-panel so that a mismatching usually cannot be done. Please assure the grounding of every component (BMS, Coax cables as well as Antennas/dishes) to avoid voltage differences between every device. The grounding should also be fit to earth potential to secure them against lightning influences.
The BMS supports cascading to a following unit to double or even multiply the needed output numbers. (32 -> 64 -> 96…) A cascading of more than 7 units is not recommended because of the attenuations of each. The cascade units should disable the power
Before you connect the both power supplies to the power source by the power cords, please connect all coax-cables and the max. 4 LNB’s or the optical ­ electrical fibre receiver to it.
Please take care about not making any Coax- shortages and check the cables before power connecting. The device runs with only one PSU connected. The 2nd PSU is in standby just in case the first one will fail ­ and will take over the power-loss job. So it is recommended not to connect them both to the same power-line and fuse system:

AC 220V 50Hz supplying please! Both have one small fuses ­ just in case something happens… control these.

Remark: The LNB-powering can be switched OFF (default is = ON) by the front panel switch.
Connected optical receiver -> electrical changer installed before the unit in between LNB’s and the SAT Inputs of the BMS-1732K -like our BFR-41 or similar- do not need the LNB powering ON ­ so you can switch it to OFF.
Active Terrestrial Input and distribution to every output:
The unit comes with an additional terrestrial Input F-Connector serving DVB-T/T2 frequencies to pass through to the output receiver ports. The terrestrial output depends of course from the amount of energy you provide into its Input. These needs to be carefully balanced and eventually before the switch input: Attenuated or amplify to raise best conditions for the pathway of the combined Terrestrial and satellite frequency range. As example for an active T-Version: 5dB difference which means the terrestrial output signal is 78% less (remember: 3dB = 50%) at the Multiswitch output by optimal Input values. So the signal quality -as a distribution component- to all the end user wall-outlets is much better by the active internal T-Amplifier- but need to be balanced to not overload it.

Shown is a good quality output level of 80 dBµV directly from a BLANKOM 32 -> 32 -Multiswitch cascaded output. The first 2 showing ASTRA Satellite high band while the 3rd shows Eutelsat Hotbird 13°E on DiSEqC SAT Pos. 2 with a better adjusted LNB at the dish(es). So your signal quality depends on: Dish direction and angles, LNB focus and angle and also its LNB-quality and the cable length and quality.
