REC OUT PARAMETER REQUEST : 52[H] 4F[H] 4D[H] 33[H],32[H] (‘ROR1,2’)

This command is used to read parameter of the desired single channel of the REC OUT 1 and 2 from the SRP-X700P. The commands that correspond to the respective channels are shown below.

CHANNEL

Command

 

 

REC OUT 1

52[H] 4F[H] 52[H] 31[H] ‘ROR1’

REC OUT 2

52[H] 4F[H] 52[H] 32[H] ‘ROR2’

 

 

Packet format

52[H] 4F[H] 52[H] 31[H] “parameter” 0D[H]

(In the case of REC OUT 1)

Parameter

Specify the scene No. of the scene memory that you want to read, as the parameter.

Method of specifying the scene No. is the same as that of the GROUP FADER command. See page 29.

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 the 9 bytes of the REC OUT1, 2 commands’ parameter from which the scene No. is exempted.

REMOTE : 43[H] 53[H] 49[H] 4F[H] (‘CSIO’)

This command is used to set the CONTROL S OUTPUT and the PROJECTOR CONTROL.

Packet format

43[H] 53[H] 49[H] 4F[H] “parameter” 0D[H]

Parameter

The parameter consists of the 24 bytes all the time in the order as shown in the table below.

The 24th byte should always be set to the fixed value (30[H] (‘0’)).

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.
