FIRMWARE VERSION REQUEST : 52[H] 56[H] 45[H] 52[H] ( ‘RVER’ )

This command is used to read the version number of the SRP-X700P firmware.

Packet format

52[H] 56[H] 45[H] 52[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 consists of the 8 bytes all the time in the following order.

byte

Parameter name

 

 

1st-7th

FIRMWARE VERSION

 

 

8th

30[H] (‘0’) fixed

 

 

FIRMWARE VERSION (1-7th byte)

The 7-bytes ASCII code indicate the firmware version of the SRP-X700P.

Example: When the firmware version is 1.00

41[H] 31[H] 2E[H] 30[H] 30[H] 20[H] 20[H] 20[H] 30[H] 0D[H] ( ‘A 1 . 0 0 s s s 1 CR’ ) (“s” indicates the space. )

FR SETUP : 43[H] 46[H] 52[H] 53[H] (‘CFRS’)

This command is used to indicate start/stop of setting up the feedback reducer, to the SRP-X700P.

Packet format

43[H] 52[H] 53[H] 41[H] “parameter” 0D[H]

Parameter

Specify the channel that you want to implement setup, as the parameter.

By sending the command CANCEL (37[H]), you can stop the setting up.

CHANNEL

 

MIC1/WL1

31[H] (‘1’)

 

 

MIC2/WL2

32[H] (‘2’)

 

 

MIC3

33[H] (‘3’)

 

 

MIC4

34[H] (‘4’)

 

 

MIC5/LINE1

35[H] (‘5’)

 

 

MIC6/LINE2

36[H] (‘6’)

 

 

CANCEL

37[H] (‘7’)

 

 

You can check the progress status of the feedback reducer setting up using the STATUS REQUEST command or the ALL STATUS REQUEST command that are described later.

When setting up is complete, the SRP-X700P turns ON the feedback reducer automatically.

You can acquire the parameter of the notch filter that is set during the setting up, using the MIC INPUT STATUS REQUEST command.

Example: When setting the MIC1/WL1 feedback reducer to the automatic setup

43[H] 52[H] 53[H] 41[H] 31[H] 0D[H] (‘C F R S 1 CR’)

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.
