Setting BRAVIA

BRAVIA Professional Display has a serial port. But the connector is not D-sub which is widely used. It is 3.5 mm stereo mini jack. I personally recommend to use a USB-to-pin-jack TTL Serial Adapter Converter Cable (FTDI chip) to connect your PC and BRAVIA.

cable

The BRAVIA Serial Control is disabled by default. Before you use this module, you have to enable the BRAVIA Serial Control. Visit the official page, see the section "Set up BRAVIA Professional Display" for details.

Quick Start

Getting status

The BRAVIA Serial Control enables you to retrieve some status or setting modes. The sample code below retrieves the power status of the BRAVIA.

// BraviaSerialControl constructor
const BraviaSerialControl = require('node-bravia-serial-control');
// BraviaSerialControl object
const bravia = new BraviaSerialControl({ path: '/dev/ttyUSB0' });

// Open the serial port
bravia.open().then(() => {
  console.log('Opened.');
  // Retreive the power status
  return bravia.getPowerStatus();
}).then((res) => {
  // Show the result
  console.log(JSON.stringify(res, null, '  '));
  // Close the serial port
  return bravia.close();
}).then(() => {
  console.log('Closed.');
}).catch((error) => {
  console.error(error);
});

In the code above, the variable bravia is a BraviaSerialControl object. you can retrieve the status calling the getPowerStatus() method implemented in the BraviaSerialControl object.

The code above will output the result as follows:

Opened.
{
  "status": false
}
Closed.

As you can see the code above, you have to open the serial port using the open() method before accessing the BRAVIA.

Changing mode

The BRAVIA Serial Control allows you to change various types of status or mode of the BRAVIA. For example, you can change the picture mode using the setPictureMode() method:

// BraviaSerialControl constructor
const BraviaSerialControl = require('node-bravia-serial-control');
// BraviaSerialControl object
const bravia = new BraviaSerialControl({ path: '/dev/ttyUSB0' });

// Open the serial port
bravia.open().then(() => {
  console.log('Opened.');
  // Set the picture mode to "cinema"
  return bravia.setPictureMode({ mode: 'cinema' });
}).then(() => {
  // Show the result
  console.log('Done.');
  // Close the serial port
  return bravia.close();
}).then(() => {
  console.log('Closed.');
}).catch((error) => {
  console.error(error);
});

Emulating IR command

The BRAVIA Serial Control supports the SIRCS (Sony IR Control System) emulation. That is, you can emulate IR commands using this module.

// BraviaSerialControl constructor
const BraviaSerialControl = require('node-bravia-serial-control');
// BraviaSerialControl object
const bravia = new BraviaSerialControl({ path: '/dev/ttyUSB0' });

// Open the serial port
bravia.open().then(() => {
  console.log('Opened.');
  // Emulate the CC (Closed Caption) button on the remote
  return bravia.emulateSircs({ code: 'cc' });
}).then(() => {
  // Show the result
  console.log('Done.');
  // Close the serial port
  return bravia.close();
}).then(() => {
  console.log('Closed.');
}).catch((error) => {
  console.error(error);
});

BraviaSerialControl object

Creating BraviaSerialControl object

In order to use this module , you have to get the BraviaSerialControl constructor loading this module, then create a BraviaSerialControl object from the constructor as follows:

// BraviaSerialControl constructor
const BraviaSerialControl = require('node-bravia-serial-control');
// BraviaSerialControl object
const bravia = new BraviaSerialControl({ path: '/dev/ttyUSB0' });

In the code snippet above, the variable bravia is a BraviaSerialControl object. The BraviaSerialControl object has a variety of methods for controlling the BRAVIA as described in sections below.

The constructor takes a hash object containing the properties as follows:

Property Type Required Description
path String Required The identifier of the serial port (e.g., "/dev/ttyUSB0", "COM3")
interval Integer Optional Command interval (msec). The value must be an integer in the range of 0 to 1000. The default value is 500 (msec).

The BRAVIA Serial Control spec says that "Set the command interval to at least 500 ms.". This module automatically handles the constraint. Basically, you don't have to care about the constraint. For example, chaining promises below works well:

// Open the serial port
bravia.open().then(() => {
  console.log('Opened.');
  // Change the external input to "TV"
  return bravia.setInput({ type: 'tv', port: 1 });
}).then(() => {
  // Set the brightness to 50
  return bravia.setBrightness({ value: 50 });
}).then(() => {
  // Change the picture mode to "cinema"
  return bravia.setPictureMode({ mode: 'cinema' });
}).then(() => {
  // Emulate the CC (Closed Caption) button on the remote
  return bravia.emulateSircs({ code: 'cc' });
}).then(() => {
  // Power off
  return bravia.powerOff();
}).then(() => {
  // Show the result
  console.log('Done.');
  // Close the serial port
  return bravia.close();
}).then(() => {
  console.log('Closed.');
}).catch((error) => {
  console.error(error);
});

Actually, BRAVIAs of recent years might work well even if the interval is shorter than 500 msec. At least, my own BRAVIA worked well even if the interval was set to 0. (The model of my own BRAVIA is KJ-43X8300D which started to be sold from 2016 in Japan.)

const bravia = new BraviaSerialControl({ path: '/dev/ttyUSB0', interval: 0 });

Connection

open() method

The open method opens the serial port and establishes a connection with the BRAVIA. This method returns a Promise object. Nothing will be passed to the resolve().

bravia.open().then(() => {
  console.log('Opened.');
});

Note that you have to open the serial port using this method before calling the methods described in the sections below. This module does not automatically open the port.

close() method

The close method closes the serial port. This method returns a Promise object. Nothing will be passed to the resolve().

bravia.close().then(() => {
  console.log('Closed.');
});

isOpen() method

The isOpen() method returns the connection status. If the serial port is open, this method returns true. Otherwise, this method returns false.

onclose event handler

The onclose event handler will be called when the connection was closed.

bravia.onclose = (event) => {
  console.log(JSON.stringify(event, null, '  '));
}

An object containing the information of the event will be passed to the callback function as follows:

  • When the connection was closed by the close() method:
{
 "intentional": true
}
  • When the connection was closed unexpectedly:
{
 "intentional": false
}

Power

getPowerStatus() method

The getPowerStatus() method retrieves the power status of the BRAVIA. This method returns a Promise object.

If the information is fetched successfully, a hash object containing the information will be passed to the resolve() function. The hash object has the properties as follows:

Property Type Description
status Boolean true: Active (On), false: Standby (Off) 
bravia.getPowerStatus()..then((res) => {
  console.log(JSON.stringify(res, null, '  '));
});

The code above will output the result as follows:

{
  "status": true
}

setPowerStatus() method

The setPowerStatus() method changes the power status of the BRAVIA. This method returns a Promise object.

Note that you have to enable the StandBy mode of the BRAVIA using the enableStandby() method in advance.

This method takes a hash object as an argument containing properties as follows:

Property Type Required Description
status Boolean Optional true: Active (On), false: Standby (Off)

If the status is not specified, this method toggles the power status. That is, if the BRAVIA is turned on, this method turns it off, and vice versa.

bravia.setPowerStatus({ status: false }).then((res) => {
  console.log(JSON.stringify(res, null, '  '));
});

If this method was executed successfully, a hash object will be passed to the resolve() function. The hash object has the properties as follows:

Property Type Description
status Boolean true: Active (On), false: Standby (Off)

The code above will output the result as follows:

{
  "status": false
}

powerOn() method

The powerOn() method turns on the BRAVIA. This method returns a Promise object.

Note that you have to enable the StandBy mode of the BRAVIA using the enableStandby() method in advance.

bravia.powerOn()..then((res) => {
  console.log(JSON.stringify(res, null, '  '));
});

If this method was executed successfully, a hash object will be passed to the resolve() function. The hash object has the properties as follows:

Property Type Description
status Boolean This property always returns true which means Active (On).

The code above will output the result as follows:

{
  "status": true
}

This method is equivalent to the code below:

bravia.setPowerStatus({ status: true })

powerOff() method

The powerOff() method turns off the BRAVIA. This method returns a Promise object.

bravia.powerOff().then((res) => {
  console.log(JSON.stringify(res, null, '  '));
});

If this method was executed successfully, a hash object will be passed to the resolve() function. The hash object has the properties as follows:

Property Type Description
status Boolean This property always returns false which means Standby (Off).

The code above will output the result as follows:

{
  "status": false
}

This method is equivalent to the code below:

bravia.setPowerStatus({ status: false })

togglePowerStatus() method

The togglePowerStatus() method toggles the power status of the BRAVIA like the power button on the remote. That is, if the BRAVIA is turned on, this method turns it off, and vice versa. This method returns a Promise object.

Note that you have to enable the StandBy mode of the BRAVIA using the enableStandby() method in advance.

bravia.togglePowerStatus().then((res) => {
  console.log(JSON.stringify(res, null, '  '));
});

If this method was executed successfully, a hash object will be passed to the resolve() function. The hash object has the properties as follows:

Property Type Description
status Boolean true: Active (On), false: Standby (Off)

The code above will output the result as follows:

{
  "status": true
}

This method is equivalent to the code below:

bravia.setPowerStatus()

enableStandby() method

The enableStandby() method enables the StandBy mode of the BRAVIA. This method returns a Promise object.

The StandBy mode is disabled by default. If you want to turn on the BRAVIA using the setPowerStatus(), powerOn(), and the togglePowerStatus() methods, you have to enable the StandBy mode in advance.

bravia.enableStandby().then((res) => {
  console.log('Done.');
});

disableStandby() method

The disableStandby() method disables the StandBy mode of the BRAVIA. This method returns a Promise object.

bravia.disableStandby().then((res) => {
  console.log('Done.');
});

Input

getInput() method

The getInput() method retrieves the current selected external input. This method returns a Promise object.

If the information is fetched successfully, a hash object containing the information will be passed to the resolve() function. The hash object has the properties as follows:

Property Type Description
type String "tv", "video", "component", "hdmi", "pc", or "shared"
port Integer Port number 
bravia.getInput().then((res) => {
  console.log(JSON.stringify(res, null, '  '));
});

The code above will output the result as follows:

{
  "type": "hdmi",
  "port": 2
}

When the type is "tv", the value of the "port" does not seem to be a channel number. The BRAVIA Serial Control specification does not provide any information about that.

setInput() method

The setInput() method changes the current selected external input. This method returns a Promise object. Nothing will be passed to the resolve().

This method takes a hash object as an argument containing properties as follows:

Property Type Required Description
type String Required "tv", "video", "component", "hdmi", "pc", or "shared"
port Integer Required 1 - 5 (The maximum number depends on the type)

If the type is set to "tv", the value of port must be 1.

Note that the BRAVIA does not return any error even if a type that the BRAVIA does not support is specified.

bravia.setInput({ type: 'hdmi', port: 1 }).then((res) => {
  console.log('Done.');
});

The actual maximum value of the value depends on your BRAVIA. Some model might not support the vertical shift.

bravia.shiftScreenPosition({ h: -3, v: 0 }).then(() => {
  console.log('Done.');
});
