NOTE: The factory default is 19200 baud; however, the player memorizes the transfer speed each time the power is cycled.

3.2Communication with a Computer

The DVD-V5000 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 when 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.
