Communication with a Computer

The DVD-V8000 communicates to the computer through the RS-232C port
using pins 2 and 3 for communication and Pin 1 for grounding in case of
using 15-pin D-sub connector or Pin 5 for grounding in case of using 9-pin
D-sub connector. Control or “handshaking” lines other than the TxD and
RxD connections are not required. Please refer to the diagram below for
clarification.

Some computers require the CTS port to be set to HIGH during
communication. It is best to connect the CTS and DSR port on the computer
to the DTR port on the player. During normal operation the player’s DTR is
set to HIGH thus the unit is able to receive a command at any time.
