3.1 Serial Interface Specifications
3.1.1 Signal Interface
The signal interface is a standard RS-232C connection.
3.1.2 Data Type
Data Length: 8 bit
Stop Bit: 1 bit
Parity bit: No Parity
3.1.3 Data Transfer Speed (Baud Rate)
The data transfer speed may be set to either 4800, 9600 or 19200
baud through the Advanced Setup Menu screen or with the Advanced
Feature Menu Set command (refer to the DVD-V8000 Operating
Instructions for command description).
NOTE: The factory default is 4800 baud; however, the player
memorizes the transfer speed each time the power is cycled.
3.2 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.

D-sub connector
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.
