7.7 Recall of a preset
A previously stored preset can be activated.
The host must send the following sequence:
RNN
followed by
CR
where: R is the character Hex 52
NN is the preset number (from 01 to 08)
Example: If the preset identified by the number 5 is to be recalled, the host will
send the following sequence on line: 52 30 35 0D
The TZ05 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
WARNING
Remember that presets 01 to 04 can be saved and
recalled also using the keypad and remote control
If a preset has been recalled, at subsequent power-ons
the unit will be set to the same status.

The TZ05 connects a video input to the preview output.
The host must send the following sequence:
vXX
followed by
CR
where: v is the character Hex 76
XX is the video input (from 01 to 04)
Example: To switch video input 4 to the preview output, the host will send the
following sequence on line: 76 30 34 0D

(Hex 06) if the command has been performed correctly
