1.8. Electrical connections
1.8.1. DVI inputs and outputs
DA2DVI-Pro provides 29 pole „digital only” DVI-I connectors for input and output
connections. Always use high quality DVI cable for connecting sources and
displays.
The input has a built-in signal detection circuit with a LED indicator located on the
front panel. The LED lights green, if the input connector senses a valid DVI signal.

Cable length at inputs
DA2DVI-Pro has an advanced built-in cable equalization circuit, which
automatically provides cable length compensation. This circuit extends the
maximum usable cable length to 60 meters using high quality 22AWG copper cable
at WUXGA 1920x1200 graphics resolution.
