7.0 COMPUTER CONTROL

All the functions of the TZW 203+ switcher can be computer-controlled simply sending a
hexadecimal character.

RS 232 standard transmission must be at 8 bits

1 stop bit, no parity. Speed is 9600 baud.

The character must be sent to pin 2 of the sub-D 15 v. f. REMOTE conn. located on the
back of the machine, The ground is pin 7.

The correspondence between the code sent by the computer and the functions activated
on the TZW 203+ is shown in the table below.

The AUTOSWITCHING and RGB MUTE commands are de-activated repeating the
command or sending the code of another command.

Pressing a key on the built-in keyboard, the
