Chapter 1 Product Outline
1.1 Outline
NDS357X IRD is DEXIN‟s new design which integrates demodulation, de-scrambler in one case
to convert RF signals into TS output after re-mux.
It is a 1-U case which supports 4 tuner inputs. The 4 CAMs/CIs accompanied can decrypt
programs input from encrypted RF, ASI and IP. The CAM requires NO unsightly external power
cords, cables, or additional remote control device.
BISS function is also embedded to descramble programs from any input.
Its pluggable structure design greatly facilitates the change of Tuner modules as needed.
To meet customers‟ various requirements, NDS357X is also equipped with 1 ASI and 1 IP input
for re-mux, and output with 2 ASI ports and IP port.
1.2 Features
4 DVB-S/S2 Tuner inputs (DVB-C, T/T2, Optional)
1 ASI & 1 IP (UDP) input for re-mux
One CAM can decrypt multiple programs from Tuners/ASI/IP
Support BISS descrambling
IP (1 MPTS & 8 SPTS) over UDP and RTP/RTSP output; ASI out
Support maximum 128 PID mapping per input
Pluggable and changeable demodulator modules
LCD display, Remote control and Firmware, web NMS management
Updates via web
Best quality and breakthrough price

2.2.3 Grounding Requirement
All function modules‟ good grounding is the basis of reliability and stability of devices.
Also, they are the most important guarantee of lightning arresting and interference
rejection. Therefore, the system must follow this rule.
Coaxial cables outer conductor and isolation layer should keep proper electric
conducting with the metal housing of device.
Grounding conductor must adopt copper conductor in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.
Users should make sure the 2 ends of grounding wire well electric conducted and be
antirust.

NDS357X IRD User‟s Manual
7 / 41
It is prohibited to use any other device as part of grounding electric circuit
The area of the conduction between grounding wire and device‟s frame should be no
less than 25mm2.
2.2.4 Frame Grounding
All the machine frames should be connected with protective copper strip. The grounding
wire should be as short as possible and avoid circling. The area of the conduction between
grounding wire and grounding strip should be no less than 25mm2.
2.2.5 Device Grounding
Connecting the device‟s grounding rod to frame‟s grounding pole with copper wire.
2.3 Wire’s Connection
The grounding wire conductive screw is located at the right end of rear panel, and the power
switch, fuse, power supply socket is just beside ,whose order goes like this, power switch is
on the left ,power supply socket is on the right and the fuse is just between them.
Connecting Power Cord
User can insert one end into power supply socket, while insert the other end to AC
power.
Connecting Grounding Wire
When the device solely connects to protective ground, it should adopt independent way,
say, share the same ground with other devices. When the device adopts united way, the
grounding resistance should be smaller than 1Ω.
Caution:
Before connecting power cord to NDS357X IRD, user should set the power switch to
“OFF”.
2.4 Signal Cable Connection
The signal connections include the connection of input signal cable and the connection of
output signal cable. The details are as follows:
