From this moment on, each time one of the input buttons is pressed, the input corresponding
to the button pressed is switched immediately to output 12.
When output 12 acts as PREVIEW,
the led of the OUTPUT 12(PW) button is ON.
b) Programming of output 12 as normal output:
- Press the "MODE" button and that of output 12 at the same time. Switching off of the built-
in led of the button of output 12 indicates that function change has been performed.
c) Programming of the default configuration:
- Press the MODE button for 2 seconds. Flashing of the built-in leds indicates saving of
current machine status as configuration at power-on.
Subsequent RECALLS from keypad or computer modify the default configuration which will
correspond to the last status recalled.
Saving of 8 machine states and subsequent recall (RECALL):

WARNING
Remember that switching operations invoked by a
RECALL command are not performed "through blank"
d) Enabling / Disabling of the IR remote control:
MODE at power-one Enabling of reception from IR remote control
MODE at power-one Disabling of reception from IR remote control
7.4 AUDIO SWITCHING CONTROL
The host must send the following sequence:
AXXYY
followed by
CR
where: A is the character Hex 41
XX is the output (from 01 to 12)
YY is the audio input (from 01 to 16)
Warning: if YY is 00 the output audio will be set to 0 Volt
Example: To set 0 volts on audio output 8 the following characters must be sent on line: 41
30 38 30 30 0D
The TZM1612 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
7.5 STATUS REQUEST
The host must send the following sequence:
D
followed by
CR
where:
D is the character Hex 44
The matrix replies with a sequence of 24 couples di ASCII characters followed by CR:
YY
video input present on bus 1 (from 01 to 16)
ZZ
audio input present on bus 1 (from 01 to 16)
“ “ “ “
“ “ “ “
YY
video input present on bus 12 (from 01 to 16)
ZZ
audio input present on bus 12 (from 01 to 16)
CR
WARNING
If the matrix replies 00 (or 30 30 in line), this means that that output is
at high impedance in the case of the video and at 0 Volts in the case of the audio.
