Chapter 2 Video Port Pin-outs
The DuraVIS 3000 is equipped with two DB15HD input ports: One that is labeled DVGA/VGA and the other
labeled EVGA. Input power is applied on pins 11 and 12 of either input port. You can supply the power on the
same connector as the video signal, or you can supply power on the unused connector. For Instance, if you
were supplying an EVGA signal, you could apply the power to the EVGA connector or the DVGA/VGA
connector. Be sure to only use one power supply.
The following tables indicate the pin-outs of the video ports of the DuraVIS 3000. Figure 2 depicts the
signal names and pin assignments for the DVGA/VGA high density DB 15 connector. Figure 3 depicts the pin-
out of the EVGA high density DB 15 connector.
DVGA/VGA signals
DVGA (Differential VGA) is a video format created by Parvus Corporation to drive VGA signals over long
distances. DVGA requires all of the signals of a regular VGA cable plus pins 9 and 10. See Table 1.
The DVGA/VGA port on the display is able to handle two video formats: DVGA and VGA. The display will
automatically detect the video format (VGA or DVGA) and display the video image to the LCD.
The VGA/DVGA interface will support
Standard VGA
or
Parvus Differential Sync VGA
via this connector. The
Video pin-out signal connections are shown in the table below. NOTE:
While the display supports VESA VGA
signals, the interface connector is NOT a VESA VGA port. Care should be taken when connecting to this port to
ensure proper signal connections. When used with VESA VGA only the 9 Video signals should be connected,
with all other pins left unconnected. A PC DB15HD VGA Cable should not be used with this interface connector.
