4.1. INPUT
The DA1910SX uses a 15-pin HD connector for
input, which is compatible with standard VGA pin-
outs. This allows the connection of a computer
using coaxial cables to a 15-pin HD connector
cable. This allows greater flexibility and versatility of
the DA1910SX. The input and output cables for
various computers are available.

4.2. MAIN RGBHV OUTPUT
BNC connectors are considered standard
connectors for audio-visual systems. They offer a
better quality connection for high-resolution video
signals. They also allow easy cable maintenance in
the field. This output offers RGBHV, RGBS, and
RGsB output signals (RGsB type input is pass-
through only). With these connectors, the
DA1910SX can be connected to compatible
projectors using 4 coax or 5 coax cables.
