Olevia has several TV's with rs232 serial control ports. These TV's can be controlled by LMCE with some tweaking. Some of them use the standard DB-9 plug, while others require a unique cable made by olevia. A template has been created as well as a plug an play script (included with the 0810 beta 2 release.

The Template (2030) supports Olevia LCD TVs with an ATI Image Processor (2XXT and 5XXT) as well as possibly others. This was developed and tested on a 232T.


The model used for development (232T) has:
1 Component
1 S-Video
1 Composite

Ruby Codes

Here are the official codes from olevia for the 2xxT series. Olevia emailed me and told me that these codes should work for the 227V, 232V, and the 232T. Perhaps others as well, but those three for certain. pdf

PNP Script

The following script will automatically detect this TV. Note that after a firmware upgrade, the TV used to test this implementation gives an intermittent response when querried by the PNP script. This sometimes causes the script to miss this TV in configuration and require a manual addition of this device.

The script is 20_OleviaTV_ATI.sh

#Play and Play script for Olevia TV's Models Numbers:2XXT/5XXT Possibly more
#Power Up is very slow so it requires several seconds to get feedback
#Device Template Number:2030 on my local Machine.

#The TV only responds to the "Power Status Query" command when the power is on, so we'll send the Power On command first, then sent the Query command.
#We give it a delay to allow the TV to power up
