Optional Video Cable Options
HD15 to HD15
This cable should be used when connecting the monitor to a signal source that provides analog
RGB outputs by way of an HD-15 connector.
HD-15 to 5 BNC
This cable should be used when connecting the monitor to an analog source that provides RGB
video by way of BNC connectors. There are three possible wiring schemes, depending on the
type of sync supplied by the source. The DVI-I to BNC cable can be used with all three schemes.
When the source provides composite sync on green, only three of the cable's five BNC connectors
are used. When the source provides RGB video and separate composite sync, four of the cable's
five BNC connectors are used. When the source provides RGB video and separate horizontal and
vertical sync, all five of the cable's BNC connectors are used.
