Serial Interface Specifications
In addition to the basic operations via main unit control panel
and remote control unit, the DVD-V8000 is equipped with a
RS-232C serial control interface supporting connection to a
computer. Two types of D-Sub serial connectors are provided
(9-pin and 15-pin). The selection of one or the other of the
connectors is made via the ADV. SETUP menu.
Important
¶ The 9-Pin and 15-Pin connectors cannot be accessed si-
multaneously.
Connector pin assignments are as shown.

Control Functions
(a) Serial control
TxD, RxD, DTR
Serial control interface complying with RS-232C standards.
(b) Extend Terminal
SW1, SW2, SW3, SW4, SW5, SW6, SW7, SW8
Simple control of the player can be effected by connect-
ing switches to these terminals.
(c) External power control
The player’s power control can be effected via the inter-
face connector’s POWER pin.
Control is disabled when key-lock is set. Unset the key-
lock before attempting to use the external power control
function.
In the standby condition, when an H signal of 100 msec or
more is followed by a L signal, the power ON sequence is
performed. In the power ON condition, impression of the
same series of signals will produce the power OFF se-
quence, placing the player in the standby condition.
Terminal input voltage is ±12 V or less, with H signal level
of 4.5 V or above, and L signal of 0.5 V or below.

(d) Playback status output
The interface connector’s STOP_ST Pin can be used to
detect the player’s status (play/stop). The “L” signal is
detected during player stop, and the “H” signal during
playback. Since output collector output is used, pull-up
should be to maximum 12 volts (50 mA).
