Cascade dSCR-Switch for use with a Quattro-LNB
1) Diagnostic LED's: Special high power startup mode: status LED's blink alternating GREEN and
RED. This is a special mode active when starting up the device (when the trunks are powered, not
when STBs power the unit). In this mode, the unit will consume the maximum power. This allows
the installer to check that there will be adequate power for the system under full (SCR) load. This
"High power startup" mode gives the installer a 15-second window to check the performance of
the power supplies. After 15 seconds, the unit will go into SCR or Legacy mode.
If the voltage level on the trunks is too low for the unit to operate, then the Power up Diagnostic
LED will be orange, so connect an extra DC supply to the DC input.
If the voltage level on the trunks is OK, then the LED will be green.
2) STB Power to Trunk Switch. There is always DC pass-through on the sat-trunks
OFF This is the default state, as trunks will feed all cascaded units and the LNB. Power comes from
DC inserted at the "DC Input" of 1 or more cascaded units.
ON The STB will feed the unit and the LNB. This is only allowed when 1 unit is used in the system.
From the moment 2 are cascaded, the position "OFF" should be selected. Otherwise, 1 STB will
need to feed all units.
5) Terrestrial amplifier
The Terrestrial trunk has an integrated amplifier that can be turned into bypass- or amplifiedmode.
Only in bypass mode, DOCSIS signals can pass through.
The Terrestrial trunk should always be terminated with a 75-Ohm terminator.
7) dSCR Modes:
The default mode is Legacy Mode. The module will automatic switch from Legacy to SCR mode
upon the first DiSEqC command when a SCR set top box is connected. If SCR mode has been
activated, that specific output needs to be powered-off to go back to Legacy Mode.
SCR mode: status LED slow blinking green. When a compatible Set Top Box is connected and set in
"SCR Mode" up to 16 User Bands can be generated and can be tuned independent of each other to
any LNB input and transponder. The MSU is compatible with the Sky, EN50607 and EN50494
CENELEC-standard.
Legacy mode: status LED solid green. When a Legacy Set Top Box (non-SCR Compatible) is
connected to any of the ports, the dSCR works like a standard multiswitch allowing only one tuner
to be connected to each output and allowing the tuner to select a single band, polarity and
frequency from the relevant transponder using 13/18 V and 0/22 kHz tone switching.
To prevent fire, short circuit or shock hazard:
- Do not expose the unit to rain or moisture.
- Install the unit in a dry location without infiltration or condensation of water.
- Do not expose it to dripping or splashing.
- Do not place objects filled with liquids, such as vases, on the apparatus.
- If any liquid should accidentally fall into the cabinet, disconnect the power plug.
To avoid any risk of overheating:
- Install the unit in a well aery location and keep a minimum distance of 15 cm around
the apparatus for sufficient ventilation
- Do not place any items such as newspapers, table-cloths, curtains, on the unit that might
cover the ventilation holes.
- Do not place any naked flame sources, such as lighted candles, on the apparatus
- Do not install the product in a dusty place
- Use the apparatus only in moderate climates (not in tropical climates)
- Respect the minimum and maximum temperature specifications
To avoid any risk of electrical shocks:
- Connect apparatus only to socket with protective earth connection.
- The mains plug shall remain readily operable
- Pull out power plug to make the different connections of cables
- To avoid electrical shock, do not open the housing of adapter
