2Overview
2.1Function and Application
DVB-S2 modulator supports 2×ASI input and outputs DVB-S2 RF signal by QPSK/8PSK
modulation. It uses advanced frame structure, channel coding modulation technology. Compared
with DVB-S modulator, it increase 50% of the transmission capacity under same condition and it
has stronger reception capacity under same spectral efficiency. This modulator complies with
DVB-S2 EN302 307 and DVB-S (EN300 421) standard. It suits 1U rack and can be configured
by front panel LCD and NMS (network management software). Its high-integrated and
cost-effective design makes it widely used in varieties of digital wireless and satellite
broadcasting distribution systems.

6.4Grounding Requirement
⚫Good ground wire design is the base of the whole system, and is essential to lightning
protection and anti-interference. The system must follow above principles.
⚫Keep good electrical contact between both ends of outer conductor and shielding layer
and the appearance of metal case of the connected device.
⚫Make sure that connections of both ends of the ground wire are with good electrical
contact and prepare for corrosion prevention treatment.
⚫Do not use other device for ground wire electrical connection.
⚫The sectional area of ground wire from rack connecting to anti-thunder unit must be
greater than or equal to 25mm2
6.4.1 Rack Grounding
Ground terminals of racks in one room should be separately connected to protective are
copper bar provided by side board. And ground wire should be as far as possible short. If the
wire is too long when installing, please cut off to avoid ground wire coiling. The sectional
area of guide line of ground terminal row must be greater than or equal to 25mm2.
6.4.2 Equipment Grounding
When grounding, use guide line to connect protective area binding post to the protective
ground wire row of assembly rack.
6.5Cable Connection
6.5.1 Power Cable Connection
⚫Power jack is on the left of rear panel, power switch is at the left side of power jack, and
ground connecting screw is at the lower left side of power jack.
⚫Connecting power cable: put one end of the cable into the AC power jack and the other
(power plug) to the AC power supply.

10
⚫Connecting ground wire: when connecting alone to protective area in the room, you can
use independent ground or common ground with other equipments (like transmission
equipment) with a resistance less than 1.
6.5.2 Signal Line Connection
Before operating, user should connect all devices requiring cables.
Note:
Before connecting power cable, please turn power switch to “O”position and it’s
required to ground with power supply system.
