QM DFL-100H modulator - 2xHDMI > DVB-T/C

The QM DFL-100H is the successor of the QM SPM-2011 modulator. The main difference is the 2 power supply's in redunancy mode in the DFL-100H and the fact that this new serie has an auto-update function via internet. The 2 power supply's work redundant: if one fails, the other one takes over, which prevents system failures. Just like its successor this modulator is a powerfull all-in-one modulator which converts 2 HDMI-sources to a DVB-T or DVB-C channel.

The modulator has a built-in webserver with lots of features and a user-friendly interface. This webserver can be managed, monitored and controlled both locally and externally. QM has given the compact DFL-100H a powerfull performance. This makes the DFL-100H the ideal modulator to add HDMI-sources out of for instance a settop box, media player or HD security camera system to a CATV-installation.

Its processor monitors the status of the modulator constantly. As soon as an error occurs, the appropriate action is taken and adjusted by the DFL-100H automatically. The watchdog timers reset the device when a CPU-failure occurs.
