Figure 3-8: Connections for Port Echo Mode

The Funct B CC xmit and Funct B CC recv settings allow the
8084 or 8084AD to be configured as the transmit and receive
sides of a "VBI bridge" around video processing equipment. For
correct operation, one caption encoder must be configured as
the transmitter (select Funct B CC xmit) and the other
configured as the receiver (select Funct B CC recv). The two
caption encoders may be connected via null modem cable
between ports B of each unit. When these modes are selected,
the port B data word is set and locked to "8 none". The user is
responsible for configuring identical baud rates on the
transmitting and receiving units.
When Funct B CC xmit is selected, all caption data being
encoded onto the video will also be transmitted out of serial port
B as raw caption data.
When Funct B CC recv is selected, all upstream captions are
blocked, and the data that appears at port B is encoded directly
into the outgoing video. The internal test message is also
disabled.
