FADER LEVEL

When you specify NONE (30[H] ‘0’) as the scene No. in the 1st byte, you can establish the present setup.

At the same time, when you specify the scene No.(31[H] (‘1’) through 44[H] (‘D’)), parameters of the subsequent 2nd to 26th bytes are written in the scene memory.

For the method of setting the scene No. and index, refer to the GROUP FADER command (pages 29 and 30).

Method of setting the PEQ1-4 frequency, PEQ1-4 Q, PEQ1-4 Gain, Gain Limit and fader level is the same as that of the LINE 3 INPUT command. See pages 32 to 35.

Method of setting the REF LEVEL, Function ON/OFF and delay is the same as that of the LINE OUTPUT1 and 2 commands. See page 37.

For the packet example, see the example of the LINE 3 INPUT command on page 35. However, the parameter length becomes 26 bytes.

REF LEVEL (10th byte)

This command is used to set the reference output level [dBu].

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.
