The TZ05 is a 4X4 video and stereo audio matrix with a fifth fixed preview output.
Certain characteristics of the unit, such as the possibilit of breakawa , computer
control and the possibilit of saving and recalling 8 configurations, 4 of which
directl form the ke pad, make the TZ05 ver useful for small presentations in
teaching and medical s stems.

2.0 POWER SUPPLY
The TZ05 must be powered at 230 Vac 50Hz using the cable provided. The cable
must be terminated in the related panel plug on the left at the bac of the unit.
The panel plug is complete with fuse-holder for 5X20 fuses.
If the fuse blows, replace with a fuse with the same rating as specified on the
bac of the unit. (T 500mA).
WARNING
All operations m st be carried o t by q alified personnel only
who m st be informed of the risks of electric shock
In some countries, the power plug must be adapted to local standards. The wires
are identified according to the following coding:
- Brown PHASE (Identified with the letter L, may be red)
- Blue NEUTRAL (Identified with the letter N, may be blac )
- Yellow/Green GROUND (Identified with the letter E, may be green)
WARNING
A gro nd connection is mandatory.

5.0 LOCAL CONTROL
5.1 Switching of the signals
The 4 video and audio outputs of the unit and also the video and audio preview
outputs can be controlled from the console on the front panel.
The "MOD " button is used to select operating mode:
-Audio only (green led on)
-Video only (red led on)
-AFV (both leds on)
-Lock (both leds off, keypad locked).
To perform switching, the INPUTS-OUTPUTS sequence must be complied with,
i.e. first of all select an input and then the output to which to switch the input
selected. As regards operations:
the 4 buttons with built-in led called "INPUTS" are used to select a source. When
a source is selected, it is immediately switched to the PR VI W output.
the 4 "OUTPUTS" buttons are used to switch the previously selected input to the
output desired.
If AFV (Audio follows video) MOD has been set, the video and audio of the input
are switched to the preview output and then to the output desired; when working
in "video only" mode, only the video is switched. The same applies when working
in "audio only" mode.
Machine status is monitored on the led type matrix on the front panel of the unit.
The color of the led indicates the type of signal on the output:
-green indicates audio
-red indicates video
-orange indicates audio and video (AFV or Audio Follows
Video).

5.2 Keypad commands
Some commands of the TZ05 unit can be performed by pressing a combination of
keys. Amongst others, 4 machine states can be saved and then recalled.
It is also possible to save a default configuration so that the machine is set to this
at power-on Subsequent recalls of presettings modify this setting.
Button Function Button Function
Mode+Input1 Save status 1 Mode+Output1 Recall status 1
Mode+Input2 Save status 2 Mode+Output2 Recall status 2
Mode+Input3 Save status 3 Mode+Output3 Recall status 3
Mode+Input4 Save status 4 Mode+Output4 Recall status 4
The above presets are four of the eight that can be recalled from PC.
As explained in paragraphs 7.6 and 7.7, 8 configurations numbered from 01 to 08
can be set and recalled from PC.
The first 4 can be accessed not only from the keypad according to the method
described above but also using the IR remote control.
WARNING
Recall of a preset from the keypa , from computer or using the IR remote
control also sets the same configuration as restart
Mode for 2 sec. Save machine status (A flash of the two leds integrated in the
MODE button indicates saving has been completed).The next
time it is switched on, the TZ05 will be set to this status until a
preset is recalled from the keypad or computer.
Subsequent recalls of presets from the keypad or computer modify the default
configuration which will correspond to the last preset recalled.

3.0 SETTINGS
The unit does not have internal presettings.
WARNING
All maintenance operations must be carried out by qualified personnel who
must be informed of the risks of electric shock. Do not open the cover of the
unit without first of all removin the power cable.
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.
c) Connect a monitor to the fi ed preview output identified as VIDEO PREVIEW
WARNING
The unit will perform the switchin in the
frame interval of the si nal on input 1
To assure switchin without release,all the sources
must be synchronous with the si nal on input 1.
d) Connect the audio sources and destinations according to the screen-printed
instructions on the rear panel.
If a system of active loudspeakers is available, this can be connected to the fi ed
preview output designated AUDIO PREVIEW.
e) Power on the appliances. The unit will be set to the factory configuration which
connects inputs and outputs with the same number or in the customized
default
configuration or in the last preset recalled from keypad or from computer.
WARNING
To save a confi uration and activate this at the next power-on,
press the MODE button for 2 seconds.
A flash of the two built-in leds indicates that the
confi uration has been saved.
Subsequent recalls of presets fro keypad or co puter odify the default
configuration which will correspond to the last preset recalled.
