PLCBUS-R 3012UK IR Device Controller

Basically, the PLCBUS-3012 provides a way to remotely control 1 or 2 devices that have a IR receiver by means of the PLCBUS protocol.
The PLCBUS-3012 can remember 16 PLCBUS addresses and can transmit an IR command for each ON or OFF for those 16 addresses. So in total it has a capacity of 32 IR commands.

Technical Specs:
Rating Voltage: 230V/50Hz
Static State Wastage : < 1W
IR Transmit Distance : Up to 3 meter IR emitter cable
IR Learning Distance : <5cm
IR emitter jack plug : 3.5mm
IR Signal Limitation : 38KHz, command length less than 250ms
I have tested the PLC3012 with a couple of devices:

– Loewe Xelos 5381 ZW
– Samsung HT-THX25
– Pinnacle Showcenter 1000


Setup of the PLC3012 is quite easy. The 16 addresses are divided into 4 groups, and each group has to be setup individually.
Each group has its own method of entering Setup mode:

Group 1: Press and Hold Setup Button for 5 seconds
Group 2: Press and release Setup Button once, press again and hold for 5 seconds.
Group 3: Press and release Setup Button twice, press again and hold for 5 seconds.
Group 4: Press and release Setup Button three times, press again and hold for 5 seconds.
When the PLC3012 enters Setup-mode, the 2 inidcators on the controller start flashing, indicating it is waiting for a PLCBUS ON command.
Next step is to send a PLCBUS ON Command for the Address you want to use, this can be done with a PLC4034 or a PLC1141.
I used House Code I (as in IR) for controlling the devices mentioned above.

So after sending I1 ON, the flashing stopped and the red indicator went on and stayed on.
I then used my remote control, aimed it at the IR learning receiver and pushed the Volume+ button.
When the controller has successfully received an IR command, the red LED will go off and the green one will go on, indicating that it is now waiting for an IR command to be used for the OFF-command of the address.
When the controller has successfully received a second IR command, both LEDs will start flashing again, indicating that you can go forward with programming another PLCBUS command, or you can choose to exit Setup mode by pushing the button on the controller.

One important thing to know is that when you initiate Setup-mode again for a specific group, all stored IR commands learned in a previous setup for that group are erased.
So when i setup the Volume+/- for address I1 in Group 1 for my Samsung, and wanted to add address I2 for controlling Channel+/- for my Loewe some time after that, i had to do both again.


I have tried learning several commands of all 3 devices, and all went well the first time. Much better then with the Pronto TSU9600 i have, where some difficult commands had to be learned more then once before they were ok.
When controlling things like Volume or Channel with the PLC3012, you’ll understand it takes some time before the IR command hits the device.
So if you like loud music and do Volume control with the PLC3012, be sure to have the Mute learned to, for when the phone rings…

The IR emitter that came with the controller seems to be typically designed for sticking on top of the IR receiver of the device you want to control. I checked the distance i could achieve with this emitter, but came no further then 50 cm. The PLC3012 supports IR transmitters like the Marmitek IR Eye, the kind you stick onto the device to be controlled, so it seems no there is not much to gain here.

Now where would you use such a IR controller in combination with these types of emitters?
Personally, i am not very fond of sticking things with wires on my TV, Home theater and thing like that. Especially where it is visible all the time. However, when they would be in some cabinet, this could be a good solution.

In my case a typical use of the PLC3012 could for example be controlling my airco. It is located at a place where it is not easily controlled, caused by location and orientation. Here such a ‘sticky’ IR Transmitter would be handy.
There is always a powerline nearby (much more likely then LAN for example), so that could be a nice solution.

Drill down charts for Gas usage

I purchased Chartdirector recently. Not being satisfied with the charting software i used so far, i decided to go for this product after trying several others. I think i made the right choice 🙂

While moving to Chartdirector, i read all kinds of stuff about clickable charts, a feature i couldn’t use before. This could be a really good opportunity to try and do something about not being able to keep track of detailed information on data that was getting “old”. So i decided to create a page with 4 clickable charts to get from a year-based chart down to an hour-based chart:

Clicking on one of the bars above will instantly update a chart that displays the data for all the months in the selected year.

Clicking on one of the bars of the chart above, will instantly update a chart that displays the data for all the days in the selected month.

Clicking on one of the bars above will instantly update a chart that displays the data for all the hours in the selected day.

And that is where it ends, gas usage information is stored on an hourly basis, so here you are at the level at which the information is stored, just with 3 clicks…

Loxx electronic door lock

Last week i received an electronic lock: the LoXX. With the LoXX you’re able to make an electronic lock of every doorlock. Some features:

  • easy to install
  • battery operated, so no wires
  • opening and closing of the door by remote control (with encrypted code)
  • optional automatic night lock on closing of the door
  • lock can still be operated with traditional key
  • SKG certified
  • Domotica-interface is a work in progress.

First i wanted to install it on the front door, but the lack of enough remote controls (i would need 4 of them) made me decide to install the LoXX on the back door. I made some pictures before installing the LoXX. I’m very curious how it is to live with an electronic lock on the door and especially how the other family members will cope with it… 🙂
