USER MANUAL
DIGITAL MODULATOR DMHD02
TWIN HD ENCODER • DVB-T MODULATOR • USB REC/PLAY

Congratulations on your purchase of the DMHD02
This ‘state of the art’ product, is a twin HD encoder. Two HDMI sources (A and B) can be
encoded and modulated simultaneously into one DVBT channel. Furthermore, a USB port is
available which allows you to play a .ts le instead of using input A. The .ts le and input B are
then available on the same DVBT channel.
Sequential les (e.g. le 001, le 002, le 003 etc) make it possible to play several les
after each other in a loop.
The record function allows you to record your source connected to input A in a .ts le on
a USB stick or drive.
Using DMHDiFace to operate the DMHD02 a wide scale of digital signage functions
becomes available. Using a battery powered time and date function, different les can
be played according to the schedule you can dene by hour, day, week etc.
Different recordings can be programmed at the same time using DMHDiFace

4.2 - Using a USB stick
To operate the USB menu, please rst insert a USB 3.0 memory stick and then power up
the DMHD02. With the USB memory stick connected, you can play les. Only les with the
extension ‘.ts’ can be played through this device. When you play a le, the source connected to
Input A will be interrupted and your ‘.ts’ le will be played.
5 - Programming using a PC
The settings of the DMHD02 can also be
changed using a PC.
First, please install the software DMHDiFace
on your PC. You can download this software
from our internet site http://antiference.
co.uk/product/conexer-twin-hdmi-modulator/
After installing the software, connect the
DMHD02 using a USB cable (not included)
to your computer. Then launch the program
DMHDiFace. On the display of the DMHD02
the message <USB> appears, indicating that
programming is now performed through your
PC. The following window appears on your
screen. All the functions can now be edited and
modied using DMHDiFace.
When you select a USB ‘.ts’ le, this will be played on a continuous loop.
If you want to play a selection of les, name your les sequentially eg: le001.ts, le002.ts,
le003.ts etc. If you select a le from this list to play, that le will start to play and at the end,
the DMHD02 will play the next le with a higher number. When no le with a higher number is
found, it will return to the start and play again from the rst le. Please refer to section 6.5 for
more information on how to create ‘.ts’ les or check out the www.antiference.co.uk website for
software to produce appropriate ‘.ts’ les for your DMHD02.To operate the USB menu, please
rst insert a USB 3.0 memory stick and then power up the DMNSD02. With the USB memory
stick connected, you can play les. Only les with the extension ‘.ts’ can be played through this
device. When you play a le, the source connected to Input A will be interrupted and your ‘.ts’
le will be played.
