Power ON indication LED (see Figure 1, pos. 16) glows
Green
at any of the 4 powering modes.
Then switch on receiver(s). The multiswitch will begin the process of auto-detecting which type(s) of receiver connected.
All subscriber outputs are configured to connect legacy STB (su13V / +18V/22 kHz signals), but it switches to
dynamic mode SCR/dSCR if receives a DiSEqC command according EN50494/EN50607.
Set the highest frequency UB for STB located nearest to the multiswitch and lowest frequency for STB farthest to the
multiswitch. If you install less than max. possible STB’s use lowest frequencies first.
Disconnect RF cables or STB‘s from necessary outputs to reset to legacy /
Start mode
.
PIN code
All User Bands (UB) are protected by PIN Code to prevent the set of UB from being used/disturbed by another user (see Table 2).
Default settings
1. SAT IF inputs are configured to use Ku-band Quattro LNB (SAT A, LNB Lo=9750/10600 MHz).
2. All outputs are configured to connect
Legacy
STB (+13 V/+18 V/22 kHz), but it switches to
Dynamic mode
SCR/dSCR
if receives a DiSEqC command according EN50494/EN50607. Output User Bands (UB) are the same in all subscriber
outputs (see Table 2). ). All user bands are turn off (
Start mode
).
3. PIN Codes (see Table 2 and see chapter "
Configuration
").
4. Only one UB plan is set depended of delivery region, if you need another plan see chapter "
Configuration
" or contact
TERRA UAB.
5. DC power to H trunk lines switch (see Figure 1, pos. 17) in position “
OFF
”.

onfiguration
The default setting of the device can be changed using dedicated programmer and software.
These multiswitches can be configured up to 32 User Bands (UB) per pair outputs (SRM543 total 64 UB) for use with
STB’s supporting DiSEqC commands according to standards EN50494/EN50607 (SCR/dSCR) as well as Legacy (+13 V/+18
V/22 kHz) commands. Default settings
Dynamic mode
can be changed to
Static mode
.

3. Multiswich is powered from H trunk
lines:
- building 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. 11-14).
Each dSCR output circuit is individually
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 HIGHER
VOLTAGE!
If STB’s connected to Legacy/dSCR outputs
can’t supply sufficient power for it’s own output – dSCR
power inserter with 20 V PSU should be used (one per out-
put of pair A or B).
WARNING
: Don’t exceed the current capability of power
inserter and dSCR outputs (800mA max.).
SERIOUS DAM-
AGE CAN OCCUR IF OVERLOADED!
Note
: Terr. TV amplifier can be powered from H trunk lines
(15-20 V) to minimize current consumption from STB and
keep Terr. TV operation when all STBs are OFF.
