Adding new template

Here are all the RS-232 control codes for Olevia 700 series TVs. When these models were first produced Olevia provided a chart with all of the control codes. However in newer manuals they labeled the RS-232 ports as "Service Ports" and stopped circulating the chart. Despite my port being labeled as a service port, all of the control commands worked perfectly. The commands are different for other models, so I would not expect this template to work for anything but a 700 series.

I have the 747i and have personally tested these codes.

Specify device data and parameters

On the LinuxMCE admin website go to: Advanced > Configuration > Device Templates

Select: Add manufacturer. Type: Olevia. Click add.

Select: Manufacturer 'Olevia', Device Category 'TVs/Plasmas/LCD's/Projectors' and press 'Add device template'

Description : 700 Series
Implements DCE : yes
Command line : Generic_Serial_Device
Device Category  AV TVs/Plasmas/Projection... #77
Manufacturer Olevia

Add the follow parameters under device data:

Device data
Current Data 	                                    Comments 	                    Default Value
#37 COM Port on PC(string) 	              The serial port 						
#76 COM Port ParityBit/Stop(string) 	      Parity/Stop bits (factory defaults) 	N81 		
#78 COM Port BaudRate(string)                Baud rate (factory default) 	        B115200
#157 Discrete Volume(bool) 	              Indicates if the volume on...             1 

Make sure that the check box for Allowed to Modify is checked for COM Port on PC. This is important and will cause you to go bald like me if you miss it.

'Edit Ruby code' (on A/V properties page)

'Make command group'

Click the "Help me choose" button. Type "Olevia 700 Series RS232 LCD TV" into the box. Click "Add i/r group".

'Add/remove inputs'

Click the "change/explain" link after inputs heading. Select all inputs on your TV. I selected: Component 1, Component 2, Composite, Composite 2, HDMI, HDMI 2, SVideo/YC 1, SVideo/YC 2, Tuner, Tuner 2, VGA.

Note: VGA was not a standard item, I had to add it to the list.

'Add/remove commands'

Select the follow command groups for your TV:

  • Ruby Internal Commands
  • Standard TV

Click update.

'Add Ruby Commands'

Add the following codes to each command. Note: These will be updated to include scripts that will make everything play nicely. The Olevia 700's have a nice feature that will report the current input. Utilizing this in the input select commands will prevent selecting already active inputs. Which is kind of annoying as the scripts are right now.

Adding device

You can now add the device via the LinuxMCE Admin Website at Wizard > A/V Equipment

Add device based on created template

Just search for the device template that you created and select it from the list.

Specify COM port for it

Tell LinuxMCE which com port to use.

Assing it to new room

Tell LinuxMCE which room to assign this device.

Specifiy Audio pipe connections to inputs on receiver

Tell LinuxMCE how you have thing attached to the LG TV and how the LG TV is attached to the computer.

Making Plug&Play

I have not been able to get PnP to work properly, despite the script detecting the TV correctly. If you want to play with it, here is the PnP script. You will have to change the 1931 parameter to the DeviceTamplate ID of your new template.

Copy to (on Core's and MD's): /usr/pluto/pnp/20_OleviaTV.sh

#Plug and Play script for Olevia 700 series LCDs
echo "Olevia 700 series TV Detection script queue $2"
response=`/usr/pluto/bin/TestSerialPort -p $3 -P N81 -b 115200 -t "\\BE\\05\\90\\00\\53" -i 1`

if [ "$response" = "\06\05\90\01\9c" ] || [ "$response" = "\06\05\90\00\9b" ]; then
echo "Its an Olevia 7xx TV"
/usr/pluto/bin/MessageSend dcerouter -r 0 $1 1 806 224 $2 13 "$4" 44 1931
echo "It's not an Olevia 7xx TV"
/usr/pluto/bin/MessageSend dcerouter -r 0 $1 1 806 224 $2 13 "$4" 44 0
