ONKYO INTEGRA SERIAL CONTROL PROTOCOLS CODE
Having done the basic testing, its now time to turn this test code in to an actual working HouseAgent plugin! This is really starting to get a routine for me. Looks like Robert’s weblog has more impact than he might think 😉 At least if you compare it to Robert’s 38(!!!) watts.

That’s 3 watts, acceptable power usage if you ask me. Here is a measurement of my unit in standby (done using the Greenwave PowerNode 🙂 ): Luckily, Onkyo seem to have learned from the past. Having the same amount of standby power usage would be a disaster for me, because my unit does not have a serial port to work around this issue. I was a bit worried about this blog post Robert Hekkers wrote. Of course this code is based on my favored asynchronous network engine Twisted. Here is the (uncleaned) test code I wrote: For example the time remaining on a track. Here’s a snippet of the status messages:Īs you can see, everything displayed on the LCD display, is also send over the wire. Yes, this is a truly two way protocol and it’s done damn right! I am amazed by the amount of status information being send back to my controller. The first diagram is communication from the controller (in my case a Python script) to the device, and the other diagram displays the communication back from the unit to the controller. So what does the protocol actually look like? Here is an block overview: More about this option later in this blog post. Switch the unit on and off (standby mode), in order to get power on to work I had to set the “network standby” option.After roughly one hour of coding, I was able to do the following: So after one day of random playing with this unit, I wanted to test the eISCP interface. I won’t bore you with all the other details about this unit, you can check them out here. The ethernet interface with reasonably documented (propriety) protocol known as eISCP (ethernet Integra Serial Communication Protocol) is a big plus. While this is not Onkyo’s top model, this model fits my needs perfectly. Here’s a picture of it in all its glory:Īnd the more interesting back side of this puppy: Last weekend I received my new receiver (hah, I’m a word artist!), it is an Onkyo TX-NR414.
