The switching time is user- adjustable to permit the perfect matching with the destination device. This important feature prevents annoying effects coming from LCDs when switching a signal to their input.

4x4 HIGH RES. & AUDIO MATRIX 7.0 CONTROL FROM COMPUTER VIA RS232 All functions of the TZM443 matrix can be controlled by sending or receiving hexadecimal and/or ASCII character strings via a computer. The dialogue via RS232 includes the following procedure:... - Page 10 Example: to switch the video of input 1 and the audio of input 3 to output 4, it is necessary to send the following characters in line: 42 30 34 30 31 30 33 0D The TZM443 matrix will respond: (Hex 06) if the control has been executed correctly NACK (Hex 15) if it has found incorrect transmission errors 7.3 Video switching command.
- Page 11 Example: In order to bring the audio 2 output to 0 volt, it is necessary to send the following characters in line: 41 30 32 30 30 0D The TZM443 matrix will respond: (Hex 06) if the control has been executed correctly NACK (Hex 15) if it has found incorrect transmission errors 7.5 Status Request...

Page 12: Note
4x4 HIGH RES. & AUDIO MATRIX 7.6 Creating a preset The TZM443 can create and execute up to 8 internal presets. A preset is a predetermined configuration of 8 switching points, 4 video and 4 audio, which are stored and can be recalled at any time. - Page 13 (from Hex 30 to Hex 39) Example: If the firmware release of the TZM443 is 1.0, the matrix will respond: 69 5A 30 0D 7.9 Global mode Request In addition to the configuration of the audio and video crosspoints, the GLOBAL MODE request allows you to know some machine conditions described below.
