Installation:
First rule in any Multiswitch installation are: NEVER use a too small size satellite Dish, and
NEVER use the compromise of a dual mount LNB for a multi satellite position reception on one Dish.
Correct Dish size ensures bad weather signal reservers and the best possible C/N for the rest of the
installation. Making compromises here CANNOT be fixed later in the network by adding Amplifiers!
A High Gain LNB only gives more Signal Level, but not Signal Quality. That only comes from Dish Size!
Mount the multi switch only indoor on a vertical dry surface using the available screwholes and ‘feets’.
Make sure that no supply voltage is available on the connection cables during installation.
(Temporarily turn off satellite receivers and/or their LNB supply).
Mount suitable F-connectors on the coax cable going to the satellite receivers and connect them
individually to a multi switch subscriber output (8 to 32 outputs dependent on type). Recommended
maximum cable length from switch to receiver is typically 25-30 meters depending upon cable
type/quality and satellite receiver. Far longer cable runs are possible, but be aware of possible DiSEqC
switching problems which may vary between satellite receivers.
Mount suitable F-connectors on the coax cable coming from the LNB units (or another cascaded
Multiswitch unit). Connect them to the correct inputs of the multi switch. Observe correct colour coding.
Double-check that correct SAT position and SAT polarities are connected to correct multiswitch inputs.
SAT Position (A/B) and polarity name and colour are visible on the multi switch unit label.
Preferably use a suitable outlet socket in the apartment at the satellite receiver to separate the terrestrial
RF and satellite SAT-IF signals (e.g.: TOU 01S, EDA 302 F). NOTE: The SAT outlet must have DC pass.
Outputs on the multi switch not in use should be terminated with DC-blocked 75 ohm terminators.
DC supply for LNBs and/or Line Amplifier(s) can be done via the built-in PSU (P-EU and A-EU versions)
and can be done by attaching an external power supply to any of the TMS 9XX CE cascade units.
Cascade switches can also take DC Supply from the trunk lines if a PSU is connected elsewhere in the
trunk. Please consider total system power consumption requirements and add PSUs as needed. DC-
blocks may need to be inserted to avoid power conflicts.
The switch itself only needs a receiver to work on SAT-IF (Active A-versions needs a PSU for RF to work).
Apply mains power to the installation power supply(es) only when all connections are done and you are
sure there are no short circuits present on the coax cables (use a multi-meter to check and verify).
Satellite receivers can now be connected, turned on and set up. System is ready for use.
BEWARE: A high Signal Level does not guarantee the digital quality of your signal! Make sure to use a
suitable quality Field Strength Measurement Instrument that lets you keep track of, and ensure suitable
C/N, BER and MER Levels througout the network.
