The data transfer speed can be set to either 4800 or 9600 baud on the Industrial player menu screen and/or with the Advanced Feature Menu Set command.(Please refer to the DVD-V7200 Operating Instructions and/or the Advanced Feature Menu Set command description.)

NOTE: The factory defaultis 4800 baud.The player memorizes the transfer speed every time and that is retained after the power cycle reaches completion.

3.2Communication 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.

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.
