Purpose This document was written as a reference specification for the Lexicon RT-20 Universal Disc Player RS-232 interface. 1-2. References Refer to the RT-20 User Guide for information about the RS-232 connector and RT-20 functionality. Overview The RT-20 RS-232 interface has been designed as a Master-Slave communication protocol, in which the RT-20 is the slave device. The Master-system controller is referred to as the HOST device. 2-2. Block Diagram RT-20 (SLA Device) VE HOST (Master- System Controller) RS232C cable (straight) Connector D-SUB (9pin, male) 2-3. RT-20 RS-232 Connector Pin Definition The RT-20 serial RS-232 connector is a male 9-pin D-sub connector. Detailed Description The RS-232 hardware interface specification between the HOST and the RT-20 is described below. 3-1. Physical connection HOST RT-20 TxD RxD GND RxD TxD GND (Serial Port settings) Baud Rate : 9600bps Data Bits : 8bit Parity : None Stop bit : 1bit Handshaking : None 3-2. Transmission data packets from the HOST to the RT-20 There are two kinds of transmission data packets that are described below. Command Packets The Command Packets are provided for the Host Controller to request the RT-20 to perform a specific action. Start character : '@' COMMAND : see "Data Packet COMMAND List"on page 16 End character (CR) : 0Dh S tart `@ ' CO M M AND E nd 0D h 3-2-1-2. Status Request Packets The Status Request packets are provided for the Host Controller to request the RT-20 to report specific operating statuses.
