A few more details about the wireless functionality of the professional CD-i remote Oty 07 by Strolo Datentechnik

Thanks to the excellent contributions by CD-i member Marc Naninck we can observe a few more details about the professional CD-i remote (oty07) that was originally developed by Strolo Datentechnik. You can find our original article here. It is a custom built professional CD-i remote that was used by companies at exhibitions or professional areas like commercial areas, hospitals, or any kind of company interested to have a 'Point of Information' in their home. The first time I've seen it was at Frencken Mechatronics in Eindhoven, The Netherlands. It serves as a kiosk system, allowing customers to look up information of the company, like the services they offer or the products they are selling. This was in a time with no internet! 

Interesting to observe the electronic components in the remote, especially when you compare it to the PCB of the original CD-i remote. The difference in components suggest that the function is not the same, so there must be additional features. Of course it is difficult to judge from pictures only, but until now there is no-one who can tell for sure. The picture below origins from Retrostuff:

Now a few more details are shown: There are regular AA batreries (4 pieces) inside and website The World of CD-i is doubting the ability that is could self-generate its energy (which was told us by a different source close to the project). Also the contact points are not copper-based but we see here IR leds, so the connection was wireless just like other CD-i remotes. It is possible that more versions exist, but it has been too long ago to know for sure. More details are scarce, unfortunately as The World of CD-i (just like us) has to observe everything from pictures and the only known physical remote is in the hands of RetroMan. Who knows we can see more of it in the future :) - For now a few detailed zoomed pictures to inspect the details:

First one about the Strolo inscription and the battery holder:

Nice to see the insciption 'Strolo DT', which shows they made the PCB inhouse at Strolo Datentechnik. CD-i member Omegalfa explains: "There is no need of any extra device to connect it to a CD-i player, as the IR LEDs works just like an usual CD-i remote.There is also an EPROM with a white sticker, this is where probably the configuration holding the protocols of the RC5 or RC6 or even both for a recognition by all CD-i players shells." Below you will see the IR leds:

The World of CD-i took a closer look at the electronic components inside, if you want to know more details, head over to their website here.

Thanks for sharing!
