dSCR (Digital satellite cable router) multiswitches SRM564, SRM584, SRM564T, SRM584T
Product description
Cascadable single cable wideband multiswitches SRM564, SRM584 and SRM564T, SRM584T are intended for the
distribution of satellite and terrestrial signals for up to 32 satellite tuners or receivers on each outputs pair.
The multiswitches have 4 passive Wideband SAT IF (for connecting 2 Wideband LNBs) and 1 passive Digital Terrestrial
TV (DTT) trunk lines.
The multiswitches have 2 DC input ports for expanded SAT IF distribution system feeding options and dedicated control/
configuration port (see Figure 1 and chapter „Installation instructions").
The multiswitches may be simply switched to Quattro SAT IF range input mode by dedicated switch.
SRM564, SRM564T is are cascadable single cable multiswitches with 3 pairs subscribers outputs (6 outputs total).
SRM584, SRM584T is are cascadable single cable multiswitches with 4 pairs subscribers outputs (8 outputs total).
SRM564 and SRM584 have active Automatic gain control (AGC) Digital terrestrial television (DTT) path to subscribers
outputs (see Table „Technical characteristics").
SRM564T and SRM584T have passive DTT path to subscribers outputs (see Table „Technical characteristics").
The multiswitches are intended for the distribution of satellite and DTT signals for up to 32 satellite tuners or receivers on
each outputs pair and have 7 x DC power modes for convenient DC powering options (see chapter „Installation instructions").
The devices ensures an independent access for every subscriber to any SAT IF and DTT trunk line.
These multiswitches automatically detect Legacy/SCR/dSCR commands from the receiver. The dSCR switches also
feature fully automatic level control for SAT IF and DTT (SRM564, SRM584) signals, negating the need for any gain or level
adjustments in most installations.
Multiswitch is built into a zinc alloy die cast housing for extreme interference immunity. The housing of multiswitches meets
more stringent screening requirements according to EN50083-2, class A.
Control according to EN50494/EN50607 (SCR/dSCR) commands as well as Legacy (+13 V/+18 V/22 kHz) commands.
According to the standard ETSI EN 303 354 V.1.1.1, TERR TV band amplifier of multiswitch type is Launch, selectivity
clasification 0.
Safety instructions
Installation of the multiswitches must be done according IEC60728-11 and national safety standards.
The multiswitches are powered from the stabilized power supply +20 V. This voltage is not dangerous to life.
External power supply must have a short circuit protection.
Any repairs must be made by skilled personnel.
To avoid damaging of the multiswitches do not connect the supply voltage until all cables have been connected correctly.
The device shall be mounted in vertical position with RF input connectors on the top side on a wall or other nonflamable
surface.
The multiswitches must be fixed with steel screws Ø 4-4.5 mm. The screws are not included in a package.
Do not expose multiswitches to moisture or splashing water and make sure no objects filled with liquids, such as vases,
are placed near or on the unit.
Avoid placing the multiswitches next to central heating components or direct sunlight and in areas of high humidity.
No naked flame sources, such as lighted candles, should be placed on multiswitch.
If the multiswitches have been kept in cold conditions for a long time, keep it in warm room no less than 2 hours before
powering.
The ventilation should not be impeded by covering the multiswitches with items, such as newspapers, table-cloths, curtains.
The mains socket of external power supply must be easily accessible.
