Table 2-21 Video Connector Summary
2.12.1 Connecting a CRT (J5)
Analog video signals from the video controller appear on a 10-pin dual-row header, J5. These signals
are compatible with the standard video monitors commonly used with desktop PCs. Specifications for
compatible monitors are provided in Chapter 1.
Normally, signals from J5 are connected to a standard DB-15 video connector by a “transition cable”
made from a ribbon cable connector and a short length of 10-wire ribbon cable. A transition cable
can connect the video signals to a bulkhead-mounted DB-15 or DB-9 connector, allowing any
standard CRT to be easily connected using a standard monitor video cable. The following table gives
the signal pinout of J5 and pin connections for a DB-15 connector. Pin connections for a DB-9
connector, used for some monitors, are also provided.
