Chapter 1 Product Outline
1.1 Outline
NDS3508B Tuner to IP Gateway is a head-end interface conversion device which
supports MPTS and SPTS output switchable. It supports 16 MPTS or 512 SPTS output
over UDP and RTP/RTSP protocol. It is integrated with tuner demodulation (or ASI input)
and gateway function, which can demodulate the signal from 16 tuners into IP package,
or directly convert the TS from ASI input and tuner into IP package, then output the IP
package through different IP address and ports. BISS function is also embedded for tuner
input to descramble your tuner input programs.
1.2 Features
Support 16 FTA DVB- S/S2/S2X input, 2 ASI input
Support BISS descrambling
Support DisEqc function
16 MPTS or 512 SPTS output (MPTS and SPTS output switchable)
2 GE mirrored output (IP address and port number of GE1 and GE2 are different), up to
850Mbps---SPTS
2 independent GE output port, GE1 + GE2---MPTS
Support PID filtering, re-mapping (Only for SPTS output)
Support “Null PKT Filter” function (Only for MPTS output)
Support Web operation

running.
2.2.3 Grounding Requirement
All function modules’ good grounding designs are 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 cable’s 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.
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 toAC 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 NDS3508B Tuner to IP Gateway, user should set the
power switch to “OFF”.
