CHAPTER 1 Product Introductions
General Description
SIGNAL-350 series encoder & modulator is DIPOL’s consumer electronics which allow audio/video signal input
in TV distributions and video recorded and playback from a USB port with applications in home entertainment,
surveillance control, hotel Digital Signage, shops etc.
It is an all-in-one device integrating MPEG-2 encoding and modulating to convert audio/video signals into DVB-T
RF out.
The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and
antenna etc. its output signal is to be received by a DVB-T standard TV, DVB-T STB etc.

CHAPTER 2 Safety Instruction and Installations
Safety Instructions
WARNING: Hot plug is not allowed since it may cause system halted.
To prevent fire or electrical shock, do not expose the device to rain or moisture.
The encoder modulator is powered with a voltage of 12V DC. The power supply voltage
must not exceed the recommended voltage, which otherwise may cause irreparable damage
to the device and the invalidation of the warranty. Therefore:
 Do not replace power supply with a voltage greater than 12V DC.
 Do not connect the device to the power if the power cord is damaged.
 Do not plug the device into mains supply until all cables have been connected correctly.
 Do not cut the cord.
Avoid placing the device next to central heating components and in areas of high
humidity.
Do not cover the device with elements that obstruct the ventilation slots.
If the encoder modulator has been kept in cold conditions for a long time, keep it in a warm
room minimum 2 hours before plugging into the mains.
Mount the device in vertical position with the connectors located on the top side.
When replacement parts are required, be sure the service technician has used replacement
parts specified by the manufacturer or have the same characteristics as the original part.
Unauthorized substitutes may result in fire, electric shock or other hazards.
Safety check- Upon completion of any service or repairs to this device, ask the service
technician to perform safety checks to determine that the device is in proper condition.
Installations
RISK OF damage to the unit
Mechanically handling the unit may result in damage. Do not connect the unit to the power
supply before or during assembly. Connect the unit as below instructed.
NO HOT PLUG!
1.

4.
Connect cable to RF output to STB/TV.
5.
Power supply connection: a) Connect the earth cable; b) Connect the power plug to the
unit mains connector; c) Connect the power plug to the mains socket.
Cascade installation
SIGNAL-350 unit has 1 AV analogue TV signal to RF output encoded as DVB-T Digital TV
signal.
Several SIGNAL-350 units can be cascaded in order to increase the capacity. The maximum
capacity of a series of N units is 1xN incorporated TV signals. To cascade 2 or more units,
connect the RF output of the preceding unit to the TV input (loop-through) of the next unit
(see below illustration).
Chapter 3 Operations of TS Creator Software
SIGNAL-350 encoder modulator has a function to create TS videos with the software
supplied with the product. Users can create *.ts files containing images, videos and audios in
a simple and intuitive way, and play them on a television through SIGNAL-350’s USB port.
File format supported include:
Image: JPG, PNG, BMP, GIF/Video: MP4, WMV, AVI, MPG, TS, MKV… /Audio: MP3, WAV
Installation
1.
Download our “TS Creator” software package on your PC to get the installer and its
auxiliary routine.
2.
Occasionally, if your PC hasn’t installed “Net Frame 2.0” yet, double-click
“NetFx20SP2_x86.exe” until complete the installation.
3.
Double-click
“Setup.exe” application to install the “Creator” and generate a
desktop shortcut.
Operations of “Creator”
Double-click the “Creator” shortcut icon, it will trigger an operation interface like below:
Click to add Images and videos
Click to adjust the order of Images/videos
Click to delete the Images/videos
Click to add audios
Click to set a save path for the TS video to be created.
To set time duration for every picture when
playing the video
To set the resolution for the output video
The video is transformed based on VBR (Variable Bit
Rate). The number set here represents the highest bit rate for the output video and bit rate
will varies under the number.
Users can select a encode format here according to
the standard of receiving terminal.
Users can filter the null packet to boost the video’s effect bit
rate.
A single video can be maximum 2.0 GB in size.
(SIGNAL-350 cannot play a video bigger than 2GB.)
After setting all the parameters, click
to start the transformation. Click “OK” when
it prompts “The operation completed normally.”
Click this button to stop the transformation before the operation completed.
After finishing the transform operation, users can click this button to play the
generated TS video.
File Management
After finishing the transformation, users can find out the videos files generated according the
Saving Directory. For example, we save the video in “D:\ABC” so we can find it in Disk
D\Folder ABC.
Management:
1.
Three files will be generated if the Null Packet has been filtered.
TS video for preview through the “Creator” interface by clicking “Play” button
TS video and information files: Users need to save the two files together in
the USB memory, and then SIGNAL-350 can read them and play the video.
2.
Two files will be generated if the Null Packet has not been filtered.
TS video for preview through the “Creator” interface by clicking “Play” button
TS video: Users need to save it in the USB memory, and then SIGNAL-350
can read it and play the video.
Remarks:
 All the file names are automatically generated.
 Rename the files before creating a new video to avoid covering the previous files.
 If you rename “FinalOutput-204-0.ts” or “FinalOutput-204-0.tsinfo”, always keep the
names the same (Extension excluded) and then SIGNAL-350 can read them and play the
video.
