carefully check before running.
2.5 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.
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 25 mm2.

output the corresponding program)
3) Modulator Setting
Bandwidth
There are three possible options provided for selecting bandwidth: 6M, 7M, and 8M.
When the display shows them, user just need swift LEFT and RIGHT key to choose
and repressing ENTER to confirm.
When entering “Modulator” submenu, user can configure the modulating parameters
for the 1carrier output separately:
Page 8
SD4260 S-Video/CVBS/YPbPr to DVB-T Encoder Modulator User Manual

Constellation
Four different constellations QPSK, 16QAM and 64QAM will be shown on the LCD
window. User can set constellation type with the same method mentioned above.
Transmission Mode
When user enters Transmission Mode, the LCD would show the current working
mode. User can move LEFT/RIGHT keys to select and press ENTER key to
confirm. 2K and 8K are the options:
2K: When the device works as current mode, the number of current carrier is 2048
8K: When the device works as current mode, the number of current carrier is 8192
Guard Interval
In communications, guard intervals are used to ensure that distant transmissions do not
interfere with each other. These transmissions may belong to different users (as in
TDMA) or same user (as in OFDM). The purpose of the guard interval is to introduce
immunity to propagation delays, echoes and reflections, to which digital data is
normally very sensitive. There are four possible options provided to be selected. They
are 1/4, 1/8, 1/16, 1/32. User can shift the LEFT/RIGHT keys to select and press
ENTER to confirm.

UP, and DOWN buttons to adjust the frequency and confirm by press ENTER
button.
RF Out Level
The RF attenuation range is from -30~-10dbm (77~97dbµV) with 0.1db step.
After entering this setting submenu, user can shift UP/DOWN/LEFT/RIGHT
key to set the output level and press ENTER to confirm.
RF On
This interface is to decide whether to enable the RF (carrierA) output or not.
OFF: to disable programs to output through carrierA.
ON: to enable programs to output through carrier A.

User not only can use front buttons to set configuration, but also can control and set the
configuration in computer by connecting the device to web NMS Port. User should ensure
that the computer’s IP address is different from the SD4260’s IP address; otherwise, it
would cause IP conflict.
The default IP address of this device is 192.168.0.136. (We can modify the IP through
the front panel.)
Connect the PC (Personal Computer) and the device with net cable, and use ping command
to confirm they are on the same network segment.
I.G. the PC IP address is 192.168.99.252, we then change the device IP to 192.168.99.xxx
(xxx can be 0 to 255 except 252 to avoid IP conflict).
Use web browser to connect the device with PC by inputting the Encoder & Modulator’s
IP address in the browser’s address bar and press Enter.
It will display the Login interface as Figure-1. Input the Username and Password (Both the
