OUTPUT CABLES
Both the digital and analog outputs of the DGy 201 are provided on the
DVI output connector. Purpose built cables are available commercially to
provide connections for digital interfaces or analog interfaces. The DGy
201 is provided with DVI-15 pin adapters for use with analog devices, or
alternatively an analog only output cable can be purchased that provides
a “break out” capability to separate RGB connectors or sub miniature
15-pin D connector.

CONNECTOR
The optional composite video signal input use the industry standard
75 Ω BNC connector.
Figure A-1. BNC connector (viewed from rear of chassis)
The BNC connector is designed for use with coaxial cables. Coaxial
cables are well suited for the transmission of high frequency signals over
moderate distances. Coaxial cable is commonly available with a
characteristic impedance of either 50 or 75 Ω. Video signals exclusively
use 75 Ω cable and connectors. For best signal quality it is important to
use a high quality 75 Ω coaxial cable. The use of 50 Ω cable will cause a
signal mismatch which may result in visible artifacts on video images.
Ready made cables are available commercially or can be easily
customized on site to suit your particular requirements.
