Onkyo RS232 control and automation is a powerful tool for custom installers and home theater enthusiasts. This technology allows for seamless integration of Onkyo components with other devices and systems in the home.
The RS232 interface provides a standard protocol for communication between devices, enabling automation of various functions such as volume control, power on/off, and input selection. This is achieved through a series of commands and protocols that are sent over the RS232 connection.
Onkyo's proprietary RS232 commands, such as "Power On" and "Volume Up", can be used to create custom automation scenarios and control systems. These commands can be programmed into a control system or automation software to create a tailored experience for the user.
By utilizing the RS232 interface, users can create a fully automated home theater system that responds to their every command, making for a truly immersive and engaging experience.
Onkyo Rs232
The Onkyo RS232 protocol is a way to control an Onkyo or Integra stereo receiver using a python library and utility.
A library called Onkyo-RS232 has been developed for this purpose.
It has only been tested on the Integra DTM-5.9 receiver so far.
The library should work to an extent on all Onkyo/Integra models, although this has not been extensively tested.
Volume and Input Control
The Onkyo RS232 system allows for precise control over your audio experience. You can set the volume to your desired level using the setVolume command, which has a range of 0 to 80.
Increasing the volume by 1 is as simple as using the setVolume command.
Controlling Onkyo Receivers
You can control your Onkyo receiver using the Onkyo RS232 protocol, which can be accessed through a python library and utility.
The python library, Onkyo-RS232, has been tested on the Integra DTM-5.9 receiver, but it should work to an extent on all Onkyo/Integra models.
To control your Onkyo receiver, you can use a python script to send commands to the receiver via the RS232 port.
One user successfully controlled their Onkyo receiver using a python script and a mac mini, but they experienced issues with their usb-to-serial adapters not keeping the same device name across reboots.
Some users have reported using the same protocol to control their Onkyo receivers over ethernet, but the details of how to do this are not well documented.

You can change the input on your Onkyo receiver using the setInput function, which supports a variety of inputs, including VIDEO0, VIDEO1, VIDEO2, and more.
Here is a list of the implemented options for the setInput function:
- VIDEO0 (VCR/DVR)
- VIDEO1 (CBL/SAT)
- VIDEO2 (GAME/TV)
- VIDEO3 (AUX1)
- VIDEO4 (AUX2)
- VIDEO5
- VIDEO6
- VIDEO7
- DVD
- TAPE1
- TAPE2
- PHONO
- CD
- FM
- AM
- TUNER
- XM
- SIRIUS
Each receiver model has different inputs that are supported, so be sure to check your model's documentation for the available options.
