4.1 INPUT AND OUTPUTS

The 

DA1904SX

 is a special application distribution

amplifier providing one VGA (SVGA, XGA) type
input on a 15-pin HD connector and one RGBHV
buffered input on a 15-pin HD connector. It also
provides one RGBHV buffered output on 5 BNC
connectors and one VGA (SVGA, XGA) loop output
on a 15-pin HD connector. The loop output should
be no longer than twelve feet for most applications.
Typically, a VGA-type 15-pin HD male to 15-pin HD
male cable will be used. The 

DA1904SX

 may be

used. The 

DA1904SX

 may be used with a variety of

input cable types, though the cable should be of
high quality output.
