SCENE RECALL BUTTON PARAMETER REQUEST :

52[H] 52[H] 53[H] 41[H] (‘RRSA’)

This command is used to read the scene Nos. that are set to the SCENE RECALL A to D buttons on the front of the SRP-X700P.

•Packet format

52[H] 52[H] 53[H] 41[H] 0D[H]

•Return packet format

When communication with the SRP-X700P is established with success, the parameter is returned together with ACK (41[H] (‘A’)) in the order shown below.

41[H] “parameter” 0D[H]

The parameter is the same as that of the SCENE RECALL BUTTON command.

SCENE STORE : 43[H] 53[H] 54[H] 52[H] ( ‘CSTR’ )

This command is used to store the scenes to the scene memory.

The procedure to store the scenes to the scene memory is shown below.

1.Specify the scene numbers that you want to store using the respective commands of MIC INPUT, LINE3 INPUT, LINE4 INPUT, ROUTING, LINE OUTPUT 1 and 2, LINE OUTPUT 3 through 8, REC OUT, SPEAKER OUTPUT, MUTING/LINE 4 SELECT and GROUP FADER. Then send the parameters that you want to store, to the scene memory.

2.Send the SCENE STORE command to store the scenes.

•Packet format

43[H] 53[H] 54[H] 52[H] “parameter” 0D[H]

•Parameter

The parameter consists 11 bytes all the time in the order as shown in the table below.

RS-232C specifications

The Sony RS-232C is a renowned communication standard that has been widely utilized in various electronic devices, enabling serial communication between computers and peripheral devices. This protocol is integral in various applications, including industrial automation, medical equipment, and consumer electronics.

One of the main features of the Sony RS-232C is its simplicity and ease of use. The standard utilizes a basic serial communication method, allowing for asynchronous data transmission. This means that data can be sent one bit at a time over a single channel, ensuring reliable communication over short distances, typically up to 50 feet, although longer distances can be achieved with proper cable management and signal boosters.

The technology behind the RS-232C standard employs voltage levels to represent binary data. Logic level zero is represented by a voltage between -3 to -25 volts, while logic level one is between +3 to +25 volts. This voltage differential is crucial for distinguishing between 'on' and 'off' states in electronic signaling. The standard supports data rates of up to 115.2 kbps, making it suitable for various applications, although it is generally limited in speed when compared to modern communication standards like USB or Ethernet.

In terms of characteristics, the Sony RS-232C supports both full-duplex and half-duplex communication, allowing for simultaneous transmission and reception of data, or one-directional data transfer, respectively. The protocol also includes control signals for flow control, such as RTS (Request to Send) and CTS (Clear to Send), which help manage data transmission and prevent data loss due to buffer overflow.

The RS-232C standard has 25-pin and 9-pin connector configurations, although many devices now utilize the more compact 9-pin DIN format. This legacy standard remains prevalent in industrial settings, as many devices still use RS-232 connections.

Despite the emergence of more advanced communication protocols, the reliability and robustness of the Sony RS-232C ensure that it remains an enduring choice for numerous applications. Its straightforward configuration, coupled with extensive documentation and support, makes it a favorable option for both new installations and the maintenance of legacy systems in various industries. As technology continues to evolve, the RS-232C standard remains a testament to the enduring principles of reliable communication.
