SRP-X500P RS-232C Interface Manual

1. Overview

1.1 About This Manual

This manual is the Interface Manual for the Sony SRP-X500P Digital Powered Mixer. The protocol explained in
this manual is designed for controlling the SRP-X500P Digital Powered Mixer from an externally connected
computer. This manual should be used together with the Operating Instructions and the User’s Guide.

Note
The material contained in this manual consists of information that is the property of Sony Corporation and is
intended solely for use by purchasers of the equipment described in this manual.
Sony Corporation prohibits the duplication or use of any portion of this manual without expressed written
permission from Sony Corporation for any purpose other than the operation or maintenance of the equipment
described in this manual.

In this manual, numeric values are indicated as follows:

Unmarked numbers : decimal numbers
Numbers prefaced by “0x” (e.g., 0x10) : hexadecimal numbers
Numbers enclosed by single quotation marks (‘ ’) : ASCII-converted hexadecimal numbers code

1.2 Connecting the SRP-X500P to a Computer

Connect the COM port of the computer to the REMOTE RS-232C connector of the SRP-X500P.
The REMOTE RS-232C connector of the SRP-X500P has the following specifications.

Terminal configuration : D-sub 9-pin, male, inch-sized screws
Electrical specifications : Conforms to the RS-232C standard

1.3 Communication Format

The communication format is described below.

Baud rate : 38,400 bps
Communication mode : Half-duplex start stop system (asynchronous)
Data length : 8 bits
Parity bit : odd
Stop bit : 1 bit
Flow control : None

1.4 Communication Protocol

The communication protocol is described below.

・When the SRP-X500P successfully receives a command from the computer, the SRP-X500P returns an ACK
(Acknowledge). When the SRP-X500P fails to process a command due to a reception error or other problem, it
returns a NAK (Not Acknowledge).

・When the computer sends a command, the computer waits for an ACK or NAK from the SRP-X500P. If the
computer receives a response, it can send the next command.

・If the computer does not receive a response even after 1000 ms has elapsed after the transmission of the
command, it means that the SRP-X500P did not receive the command normally. The computer should re-send the
command.

・Transmission of the command by the computer should take place within 1000 ms. If the transmission is not
completed within 1000 ms, a NAK should be returned without processing of the command.

・If the computer receives a NAK while transmitting the command, the computer should stop transmitting the
command immediately.

1.5 RS-232C indicator

When SRP-X500P is communicating with the computer, the RS-232C indicator on the front panel is lit up.

1.6 Note on Value Settings

When setting up or operating the SRP-X500P through the RS-232C connector, be sure the parameters are within
the value ranges specified in this protocol manual. The setting of values not defined in this manual may be a
cause of an operational malfunction in the SRP-X500P or a communication malfunction between the SRP-X500P
and the SRP-X500P Manager software. If this happens, the FACTORY PRESET command should be transmitted
to restore the SRP-X500P parameters to their factory settings.
Afterwards, the parameters should be set to their appropriate values.

SRP-X500P RS-232C Interface Manual

1.7 Handshake Codes

ACK : 0x41 ( ‘A’ )

When the SRP-X500P has received a command from an external computer and has processed it successfully, it
returns an ACK to the computer as notification that the command has been executed. There are cases when other
data are added to and returned with the ACK, depending on the command.
See “2. Command Reference” (page 6) for details.

NAK : 0x4E ( ‘N’ )

When the SRP-X500P fails to process a command sent by an external computer, it returns a NAK to the
computer.

DELIMITER : 0x0D ( ‘CR’ )

The SRP-X500P adds a delimiter code (equivalent to the ASCII carriage return) as the last byte of all commands.

1.8 Communication Packet Format

Communication packets are variable in data length.
A communication packet consists of command, parameter and delimiter, as shown below.

Command example:

When “C” is selected in AV/RGB INPUT ( ‘C S E L 3 CR’ )
0x43, 0x53, 0x45, 0x4C, 0x33, 0x0D
Command Parameter Delimiter

Command : The command always comprises the first four bytes.
Parameter : The length and function of the parameter varies according to the command. See “2. Command
Reference” (page 6) for details.
Delimiter : The SRP-X500P always adds the delimiter code 0x0D (equivalent to the ASCII carriage return)
as the last byte of all commands.

Example of ACK

When the SRP-X500P returns the status of the AV/RGB INPUT SELECT ( response to ‘R S E L CR’)
0x41, 0x33, 0x0D
ACK Parameter Delimiter

Parameter : The length and function of the parameter varies according to the command. See “2. Command
Reference” (page6) for details.
Delimiter : The SRP-X500P always adds the delimiter code 0x0D (equivalent to the ASCII carriage return)
as the last byte of all commands.

Example of NAK

0x4E, 0x0D
NAK Delimiter

Delimiter : The SRP-X500P always adds the delimiter code 0x0D (equivalent to the ASCII carriage return)
as the last byte of all commands.
