7.7 Recall of a preset
A previously stored preset can be re-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 05 is to be re-activated, the host
will send the following sequence on line: 52 30 35 0D
The TZ09 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
7.8 Firmware release identification request.
The host must send the following sequence:
i
followed by
CR
where: i is the character Hex 69
The TZM883R matrix replies:
i
(Hex 69)
G
high byte identifying the firmware (Hex 47)
Z
low byte identifying the firmware release (from 30 to 39)
CR
7.9 G lobal status request
The host must send the following sequence:
d
followed by
CR
where:
d is the character Hex 64
The matrix replies with a sequence of 8 couples di ASCII characters followed by CR:
YY
video input present on bus 1 (from 01 to 8)
ZZ
audio input present on bus 1 (from 01 to 8)
“ “ “ “
YY
video input present on bus 8 (from 01 to 8)
ZZ
audio input present on bus 8 (from 01 to 8)
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.
V
audio level
(from 1 to 8)
P
number of the preset activated (from 0 to 7)
T
enabling of remote control (0= disabled, 1= enabled)
A
machine address on RS485 (from 0 to 7)
S
Tx/Rx speed on RS485 (1= 2400 bit/sec, 2= 9600 bit/sec)
R
reply time (from 1 to 7, in multiples of 16 ms, or from 16 ms to 112 ms)
CR
4.0 INSTALLATION
a) Make sure that all the units to be installed are off.
b) Connect the video sources and destinations according to the screen printed
instructions on the rear panel.
WARNING
If the input loop is used, set the internal
jumpers to OFF pos.

c) Connect a monitor to the fixed preview output designated PREVIEW VIDEO
WARNING
The unit will perform the switching in the frame
interval of the signal on input 1. To assure switching without release,
all the sources must be synchronous with the signal on input 1.
d) Connect the audio sources and destinations according to the screen printing
on the rear panel.
If a system of active loudspeakers is available, this can be connected to the
fixed preview output designated AUDIO PREVIEW.
Otherwise, the audio can be monitored from the built-in loudspeaker of the unit
or from the headphones output; these are mutually exclusive.
WARNING
Local audio monitoring volume is regulated
by the OUTPUT keys when the MODE button is in the
LOCK/VOLUME position (both leds off)
(See paragraph 5.2)
e) Power on the appliances.
The factory configuration, input 1 on output 1, input 2on output 2 etc., or the last
configuration saved will be restored.
WARNING
To save a configuration and restoring it at the power on
press for 2 sec. the MODE button.
Subsequent "recall" from keypad or computer modifies the default configuration
that will correspond to the last "recall".
WARNING
