- At the C-Series the Ex-Link port is located at the VGA connector of the TV.
As the TV has TTL level serial output (3.3V) a TTL-level to RS232-level adaptor is needed,
normal RS232 Level is up to 15V which can cause seriously damage at your TV! MAX232 is such an adaptor.
- Pin 4 at the VGA connector is RX (from the TV's point of view)
- Pin 11 at the VGA connector is TX (from the TV's point of view)
- Pin 5,6,7,8 and the case at the VGA connector are GND
MAX232 adaptor circuit V1
Here is a simple circuit using a MAX232 chip to convert the signal from TTL to RS232 level. The Pinout of the connectors is shown at the circuit:
And a picture of the completely assembled board:
MAX232 adaptor circuit V2

Warning
- As written before,
do never connect your TV directly to the serial port of your PC, as the TV has TTL-level (3.3V) and the PC has normal RS232-level your TV could seriously get damaged by dircet connection!
