Activating the RS232 interface at the Sharp TV

Following the initial commissioning of a Sharp television, its serial

interface (RS232) is not yet configured for control by an external

device. The RS232 interface is only permanently activated once a

one-off initialisation command is sent through the M203 interface to

the Sharp television. Activation is done with the following steps:

1) Carry out a complete reset (see Page 8)

2) Make the settings as described in "Setup #2 – AV

Assignment", from Page 14.

3) Switch on the M51/M219 with FM Tuner. If no FM Tuner is

installed, select a source that is not linked to a television video

input in Setup #2.

4) Switch on the Sharp television with the original remote control,

using the Power button.

5) Wait until the television is ready to receive.

6) Now select a source at the M51 (or at the M219 Side room

amplifier), which is linked to a television video input in Setup

#2.

7) The television is now initialised and retains the facility to be

controlled through the serial interface, even when it is

switched off.

Please note:

If the television is changed, the process described above has to

be repeated.

Special characteristic on Input 3

The Input 3 can only be addressed by the M203 if there is already a

signal at its input. If this is not the case, the television recognises this

and ignores the control command.
