The TZ05 is a 4X4 video and stereo audio matrix with a fifth fixed preview output.
Certain characteristics of the unit, such as the possibility of breakaway, computer
control and the possibility of saving and recalling 8 configurations, 4 of which
directly form the keypad, make the TZ05 very useful for small presentations in
teaching and medical systems.

- The IR remote control
(optional)

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 back 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
back of the unit. (T 500mA).

WARNING

All operations must be carried out by qualified personnel only

who must 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 black)

- Yellow/Green GROUND (Identified with the letter E, may be green)

WARNING

A ground 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 "MODE" 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 PREVIEW output.

the 4 "OUTPUTS" buttons are used to switch the previously selected input to the
output desired.

If AFV (Audio follows video) MODE 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 keypad, 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.

6.0 INFRARED REMOTE CONTROL

The unit is equipped with a receiver for the infra-red remote control. This must be
ordered separately.(Code IRTZ05).

WARNING

The remote control is of the self-learning type. After inserting the batteries

and each time these are changed, press the "Set" key for a few seconds

WARNING

IR remote control reception is enabled and disabled

holding down the MODE button of TZ05 at power-on

The TZ05 is factory set with the remote control enabled

The following functions can be carried out using the IR remote control:

Save + IN 1÷4 Save a configuration (together with the IN keys 1÷4)
Recall + OUT 1÷4 Recall a configuration (together with the OUT keys 1÷4)

WARNING

Recall of a preset from the keypad, from computer or using

the remote control also sets the same configuration as restart

IN keys 1÷4 Input selection (or selection N° Save )
OUT keys 1÷4 Output selection (or selection N° Recall)

A, V, A+V, Lock Setting of switching mode
MUTE ON OFF Sets Mute on the monitoring audio output

WARNING

The INPUTS-OUTPUTS sequence must be complied with also using the

remote control, i.e. select first of all the source and then the destination.

WARNING

If the matrix replies 00 (or 30 30 on 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.

7.6 Creation of a Preset

The TZ05 can create and perform up to 8 internal presets. A preset is a
predefined configuration of 8 switching points, 4 video and 4 audio, saved in the
memory and which can be recalled at any time.
The presets are created from the current status

of the matrix and are maintained

in the case of a blackout.

The host must send the following sequence:
SNN followed by CR where: S is the character Hex 53
NN is the status number (from 01 to 08)

Example: If preset 5 is to be assigned to the current state of the matrix, the host

will send the following sequence on line: 53 30 35 0D

The TZ05 matrix replies:

ACK (Hex 06) if the command has been performed correctly

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 removing 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 fixed preview output identified as VIDEO PREVIEW

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-printed
instructions on the rear panel.

If a system of active loudspeakers is available, this can be connected to the fixed
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 configuration 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

configuration has been saved.

Subsequent recalls of presets from keypad or computer modify the default
configuration which will correspond to the last preset recalled.
