Installation
Getting started
For simplicity, we’ll call the ABI-MD3004SCT encoder modulator “MD3004” in this manual.
Installing DTV management program
The management program comes as an executable file, and works on a PC from Windows 7 up to Windows
10. The PC should have a spare USB interface port to connect to the MD3004.
When you install the program, it is possible that at the end of the process, Windows tells you that the
installation failed. Disregard this message as well and try running the program. If it does not work, try
installing a second time.
Preparing the HDMI sources
Please pre-configure the HDMI sources (video resolution and refresh rate, audio format and sampling
speed) and check their proper operation directly on an HDMI screen before connecting them to the
MD3004. Limit the HDMI ouput of the sources to max 1080p@24Hz. The resulting video bitrate can go as
high as 12Mbps.
Please be aware that some video sources like Google Chromecast cannot be configured individually and
will allways start up at 1080p 60HZ. There is afterwards no possibility to turn down resolution or refresh rate.
Please do not use this type of device.
It is very difficult to identify the nature of a signal distortion or failure on a end-to-end system if this step has
not been done properly on forehand.
Preparing the MD3004
The 4-input ABI-MD3004 is supplied with a 5V external power supply.
Install the unit properly, eventually ground the coax input to an equipotential safety ground.
Connect the RF output to the distribution network and the RF input to the aerial or to another MD3004’s
output in case a larger number of modulated signals is required.
Connect the power supply to mains.
Connect the 5V plug to the MD3004.
The front panel LED will light green, signalling that there is power supply.
Both rear panel’s LEDs will light red during boot-up of the unit.
The LED adjacent to the HDMI inputs will start blinking green when the unit is ready to operate.
