Pioneer LASERDISC/COMPACT DISC PLAYERS CLD-V2400 - Manual (Page 33)

The Transmission speed
4800, or 1200 baud can be selected by using the Dip Switch 2 on the back of the
player: Down = 1200 BAUD; UP = 4800 BAUD. The factory default is UP=
4800 BAUD. The BAUD rate can also be set by sending Level III commands to
Register C.
4) Connection to a Computer
The player can be connected to a computer via the RS-232C port as shown below.
It is connected with three lines: One line transmits commands from the computer
to the player to control operations. Another line transmits status responses from
the player to the computer. The third line is Ground.
The player does not use hardware handshaking. Therefore, control or “handshaking”
lines other than TxD and RxD are not required, even if the computer provides them.
Some computers, however, may require hardware handshaking. The player makes
a line available to be used, as needed, by the computer. The DTR signal is always
pulled high internally, within the CLD-V2600 & CLD-V2400.
The player is connected to the RS-232C port of the computer as follows:
See Appendix C for specific interface cable pin configurations to use to connect
various computers to the CLD-V2600 or to the CLD-V2400.
