4. Installation instructions
Read the safety instruction rst.
Installation of system according standard IEC60728-11 ensures safety of personnel and prevents apparatus against
damaging due to lightning or other sources of overvoltage surges.
Headend must be xed with steel screws Ø 4-5 mm. The screws are not included in a package.
If any RF connector on the transmodulator is not used, connect the 75 Ω load supplied.
Connect power plugs of transmodulator to the mains when potective earthing and RF cables are connected correctly.
Shielded cable is recommended for Ethernet connection.
It is recommended to connect power plugs of headend to dierent lines of the mains or one to the line directly, another
through uninterruptible power source (UPS).
System indicates error when one of PS is disconnected. Disconnected PS does not disturb working of other PS.
5. Operation
Power on the device. Yellow LEDs [7] will light on from the left to the right one by one. It indicates powering on progress.
When powering on is nished, device will run according to the latest used conguration. LEDs will indicate the status of each
channel. The led is turned o when particular demodulator is disabled. Green LEDs [7] indicates, that demodulator is active,
no errors detected. Red LEDs [7] indicates that demodulator is unlocked. Yellow LEDs indicates, that demodulator has
some reception errors.
NOTE: Please check the signal quality if the yellow LED lights up.

HEADEND ADDR. - addressing indicator. It blinks on when the device is being accesed via Web interface
2
HEADEND STATUS - error indicator. Red light indicates, that at least one error exists at the moment
3
STATUS DC OUT 1 - indicates LNB1 powering status
4
STATUS DC OUT 2 - indicates LNB2 powering status
5
STATUS POWER SUPPLY 1 - indicates correct DC voltage from power supply PS1
6
STATUS POWER SUPPLY 2 - indicates correct DC voltage from power supply PS2

Startup progress and channel status indicators:
1. Indicate the progress of startup when the device is powered on or rmware upgrade is going on.
2. Each indicator indicate input channel status when the device is up and running:
Does not glow when the input channel is inactive.
Glows yellow if demodulator have CC/BER errors related to reception.
Glows green if demodulator is active and there are no errors.
Glows red if demodulator is unlocked.
