Controlling Media Devices via Ethernet or RS232
« on: January 19, 2009, 05:08:35 pm »
I am heading over to our local AV store to look at what devices they offer w/ eth or rs232 support for a new house so that it will all be controlled with LinuxMCE.
The wiki's section, http://wiki.linuxmce.org/index.php/Have_LinuxMCE_automatically_control_the_TV_and_Stereo suggests it's all automatic but not having any devices like this I am not sure what to expect or choose.

RS232 is obvious and detailed here in http://wiki.linuxmce.org/index.php/AV_Devices
Ethernet has me a bit curious, http://wiki.linuxmce.org/index.php/Plug%26play suggests it correlates by mac address so how does one perform the initial pairing? Do I need to know the mac address before hand?

Finally, does anyone have any reco's for manufactures to look for that have decent ethernet controlled devices?

Thanks!

Ethernet-controlled devices do use MAC address for identification.  This is set in the device template definition.  Typically, a range is set based on a manufacturer's assigned MAC address range.  This gets a bit tricky when using devices from manufacturers that make more than one device used with LMCE (Roku for example).  You can always tailor your range if you'd like, however.

Appreciate the reply. So if I had 5 tv's for example whose only difference in mac address was the last octet, ab, ac, etc... what kind of issues should I expect?

Thanks!

The MAC addresses will all be in the manufacturer's range but unique. That is what you want. The pnp system will detect them all as the correct device/model and create a device based on the template you design. And because they are all unique, it will realise that they are different devices and create a new device based on the same template each time. You then just configure the room etc..
