2.3.1 Remote Sensor and the External Control Terminal
The infrared sensor and the external control (EXT CONT) terminal on the front of
the player are the interfaces that receive input from the remote control units RU-
6000T, RU-V103 and Pioneer Barcode Readers. Both remote control and barcode

commands sent from these units are transmitted in serial data streams. NOTE:
The remote sensor and the EXT CONT terminal cannot be used simultaneously.
The infrared sensor receives the RCU signals on a 48-KHz carrier, removes the
carrier, shapes the waveform, and outputs the shaped waveform. (See Figure 2-E.)
The stereo mini-plug (Figure 2-F) is used to input a signal to the EXT CONT
terminal providing a wired connection for the remote control units (RU-V6000T,
RU-V103) or a Pioneer Barcode Reader. GND Switch Data, or RCU/Serial Data are
input as signals as shown in Figure 2-G, on the next page. RCU/Serial Data is an
active-low signal. The input serial data must be asynchronous, 1200-baud, no
parity, 7-bit, and 1-stop bit serial data. The TTL level is used for the signal level.
