3.2 Communication with a Computer
The DVD-V7200 communicates to the computer through the player’s RS-232C port
using pins 2 and 3 for communication and Pin 1 for grounding. Control or
“handshaking” lines other than the TxD and RxD connections are not required.
Please refer to the diagram below for clarification.

GND Pin 1 - GND
In some computer, the CTS port should be set to HIGH during the communication.
It is the best thing to connect the CTS of the computer to the DTR of the player. In
normal operation and communication is available , the DTR in the player is set to
HIGH thus the unit is able to receive a command at any time.
