Product description
Cascadable 8 output single cable multiswitch with 4 independent signal processors is intended for the distribution of
satellite and terrestrial signals for up to 32 satellite tuners or receivers on each outputs pair.
The multiswitch have 4 passive SAT IF and 1 active Terrestrial TV trunk lines and 4 pairs subscribers outputs (8 outputs
total) and 4 x DC power modes for convenient DC powering options (see chapter „Installation instructions”).
The device ensure an independent access for every subscriber to any SAT IF or Terrestrial TV trunk line.
These multiswitches automatically detect SCR/dSCR mode or legacy format from the receiver. The dSCR switches also
feature fully automatic level control, negating the need for any gain or level adjustments in most installations. Built into a
zinc alloy diecast 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) as well as Legacy (+13 V/+18 V/22 kHz) commands.
Safety instructions
Installation of the multiswitch must be done according IEC60728-11 and national safety standards.
The multiswitch 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 qualied personnel.
To avoid damaging of the multiswitch 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 nonamable surface.
The multiswitch must be xed with steel screws Ø 4-4.5 mm. The screws are not included in a package.
Do not expose multiswitch to moisture or splashing water and make sure no objects lled with liquids, such as vases,
are placed near or on the unit.
Avoid placing the multiswitch next to central heating components or direct sunlight and in areas of high humidity.
No naked ame sources, such as lighted candles, should be placed on multiswitch.
If the multiswitch has 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 multiswitch with items, such as newspapers, table-cloths, curtains.
The mains socket of external power supply must be easily accessible.
IMPORTANT WARNINGS!
Before connecting any products to a system, it is essential to make sure the system power supply is switched off. Avoid
short-circuit or overload of any power supply. Never “HOT-SWAP” any system components as this may result in damage to
the newly introduced or existing components.
The SRM580 multiswitch is intended only for indoor installation or installation in a suitable weatherproof outdoor cabinet.
This multiswitch must not come into contact with moisture or be installed in areas of high humidity or heat.
Suitable for moderate and tropical climates.
Always mount the multiswitch securely to a wall or bulkhead panel so it cannot hang or swing on its coaxial cables as
this may strain the internal circuit board and components.
Always connect all of the coaxial cables to the multiswitch before connecting the power. These units are not designed to
be “HOT-SWAPPED” or connected to a live system.
Always be sure that connecting cables shield and multiswitch functional grounding clamp have common potential before
powering the system. Floating voltages can be created in an un-earthed system which may cause damage and can be dangerous.
Momentary short-circuit of any cables may be enough to damage the sensitive electronics within the multi-switch or the
connected system.
Always allow plenty of ventilation around the multi-switch and do not allow it to be covered with materials such as loft insulation.
We recommend at least 5 cm of airspace around the multi-switch. Digital products can get hot to the touch and require
a ow of air to avoid overheating.
SRM580 multiswitch is designed only to work with Ku band Quattro LNBs.
LNB’s and other system equipment connected to the multiswitch SAT H,Lo and H,Hi trunks inputs/outputs can be powered
from the same power supply as the multiswitch.
To avoid damage not covered by warranty DO NOT EXCEED MAX CURRENTS. See “Technical
characteristics” for max. current for external equipment.
DO NOT OPERATE THE DC POWER TO H TRUNK LINES SWITCH (see Figure 1, pos.21) unless you
totally understand the power demands of the system and conrmed they are 2 A or less. ALWAYS LEAVE
THE DC POWER TO H TRUNK LINES SWITCH IN THE "OFF" POSITION when inserting SRM580 into an
existing multiswitch installation.
Damage caused by current overload is not covered by the manufacturer’s warranty.

Installation instructions
Read the safety instruction rst.
Fit multiswich on mounting place and connect it (pay attention to the multiswitch inputs and Quattro LNB outputs marking, connect
the isolated 75Ω loads to the unused RF output F sockets), power on multiswich using one of 4 powering modes (see Table 1).
Table 1
Powering mode
”DC power
to H trunk lines
switch” position
(see Figure 1, pos.21)
Warnings and notes
1. Multiswich powered from local PSU (20V) via
DC input
(see Figure 1, pos. 20) . (Recommended for use is
PS202F 20 V PSU).
H trunk lines are DC isolated from it.
OFF
Recommended as rst choice.
WARNING: BEFORE CONNECTION
ALWAYS CHECK DC POWER TO H TRUNK
LINES SWITCH (see Figure 1, pos.21). IT
MUST BE IN POSITION "OFF"!
Note: All trunk lines preserve DC bypassing.
2.Multiswich is powered from local PSU (20 V)
via DC input and with DC passing to H trunk
lines.
In this mode H trunk lines can power in cascade
other multi-swiches (without PSU, with “DC to H
trunk lines” switch ON)
ON
WARNING: Don’t overload PSU via H trunk
lines – check total system power consumption
of multiswich and from H trunk lines (including
all other equipment connected).
Check all other system equipment connected
to H lines if it can accept 20 V. SERIOUS
DAMAGE OF IT CAN OCCUR!
3. Multiswich is powered from H trunk
lines:
- build new SCR/dSCR system (18 V - 20 V)
- upgrading old legacy systems (15 V - 18 V)
ON
WARNING: Don’t exceed the current capability of system
power supply.
SERIOUS DAMAGE CAN OCCUR IF OVERLOADED!
4. Multiswich is powered from Legacy/
dSCR (subscriber) outputs
(see Figure 1, pos. 11-18).
Each dSCR output circuit is individualy
powered directly from STB’s or from dSCR
power inserter (with 22 kHz bypass). OFF
WARNING: MULTISWITCH WILL DRAW CURRENT AND
POWER FROM PAIR OUTPUT WITH HIGEST
VOLTAGE! If STB’s connected to Legacy/dSCR outputs
can’t supply sufcient power for it’s own output – dSCR
power inserter with 20 V PSU should be used (one per
output of pair A, B, C or D).
Note: Terr. TV amplier can be powered from H trunk lines
(15-20 V) to minimize current consumption from STB and
keep Terr. TV operation when all STB‘s are OFF.
