MUTING/LINE4 Select Parameter Request | Sony RS-232C instruction

•MASTER MUTING (6th byte)

This command is used to specify muting of the MASTER A and B with the 8-bit data.

When you want to set the MUTING status, set the corresponding bit to 1. When you want to cancel MUTING, set the corresponding bit to 0.

Bit-2 to bit-7 are fixed all the time.

bit7	bit6	bit5	bit4	bit3	bit2	bit1	bit0
0	1	0	0	0	0	MASTER B MASTER A

•GROUP FADER MUTING (7th byte)

This command is used to specify muting of the REMOTE1 to 6 with 8-bit data.

When you want to set the MUTING status, set the corresponding bit to 1. When you want to cancel MUTING, set the corresponding bit to 0.

Bit-6 and bit-7 are fixed all the time.

bit7	bit6	bit5	bit4	bit3	bit2	bit1	bit0
0	1	REMOTE6	REMOTE5	REMOTE4	REMOTE3	REMOTE2	REMOTE1

•LINE4 SELECT (8th byte)

This command is used to specify the selection channel for the LINE4 SELECT.

CH

OFF	30[H] (‘0’)

A	31[H] (‘1’)
B	32[H] (‘2’)

C	33[H] (‘3’)

D	34[H] (‘4’)
E	35[H] (‘5’)

F	36[H] (‘6’)

Example: When you want to write the following channels in the scene No.1 after setting MIC1/WL1-MIC4 in the MUTING status, LINE OUTPUT7 and 8 in the MUTING status, other channels in the MUTING-released status and LINE4 SELECT in B.

43[H] 4D[H] 54[H] 53[H] 31[H] 4F[H] 40[H] 40[H] 43[H] 40[H] 40[H] 32[H] 0D[H] (‘ C M T S 1 O @ @ C @ @ 2 CR’)

MUTING/LINE4 SELECT PARAMETER REQUEST:

52[H] 4D[H] 54[H] 53[H] (‘RMTS’)

This command is used to read the muting setup of the respective input/output channels and GROUP FADER for each scene memory and to read the LINE4 SELECT setup from the SRP-X700P.

•Packet format

52[H] 4D[H] 54[H] 53[H] “parameter” 0D[H]

•Parameter

Specify the scene No. of the scene memory that you want to read, as the parameter. Method to specify the scene No. is the same as that of the MUTING/LINE4 SELECT command. See page 44.

•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 7 bytes of the MUTING/LINE4 SELECT command parameter from which the scene No. is exempted.

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.
