The TZM443 unit is a 4x4 matrix for RGBHV high resolution signals with
associated stereo audio signal.
It can be controlled with the integrated keyboard, from the computer with an
RS232 or RS485 serial interface and with an infrared remote control.
8 configurations can be saved and recalled, 3 of which directly from the keypad.
These are very useful in small presentation environments as well as in teaching
programs.

−The main cable−This manual
−The CE declaration - The IR remote control
(optional IR-TZM443)

2.0 POWER SUPPLY
The TZM443 must be powered at 230 Vac 50Hz (115Vac 60Hz on request) with the
supplied power cable. The socket of the main cable must be connected to the panel plug
placed on the left hand side of the rear panel.
The panel plug has a fuse carrier for 5X20 fuses.
In case of fuse failure, replace it with an equivalent one, as specified at the back of the
unit (T 500mA).
CAUTION
All operations must be carried out by highly skilled personnel
who must be informed on risks concerning electric shock.
In some nations it is necessary to change the plug in order to adapt it according to the
local standard types. The code for the identification of the wires is as follows:
-Brown PHASE (Marked by the letter L, it could be red)
-Blue NEUTRAL (Marked by the letter N, it could be black)
-Yellow/Green GROUND (Marked by the letter E, it could be green)
CAUTION
Grounding is compulsory

3.0 SETTINGS
The unit does not have internal setups. CAUTION
All maintenance operations must be carried out by highly skilled personnel
who must be informed on risks concerning electric shock.
Do not open the cover of the unit without previously removing the main cable.
4.0 INSTALLATION
a) Make sure that all units to be installed are switched off.
b) Connect the sources and graphic destinations according to the silk-screen printings on
the rear panel.
c) Connect the sources and audio destinations according to the silk-screen printings on
the rear panel.
d) Power up the equipment.
The unit will set up according to the factory setup so by the inputs and outputs
connected with the same number or according to the customized default configuration,
or according to the last preset recalled from the keypad or computer.
CAUTION
To store and enable a configuration to the
next switch-ons (customized default configuration),
press the MODE button for 2 seconds.
Two LEDS will flash after storing the information.
Subsequent recalls of one of the presets from the keypad or computer will change the
default configuration, thereby corresponding to the last recalled preset.
5.0 LOCAL CONTROL
5.1 Signal switching
The 4 graphic and audio outputs of the unit, as well as the graphic and audio preview
output, can be controlled through the console on the front panel.
The “MODE” button is used for changing the operation mode:
-Only audio (green LED on)
-Only video (red LED on)
-AFV (both LEDS on)
-Lock (both LEDS off, keypad locked).

Switching is carried out by following the INPUTS - OUTPUTS sequence.
Operationally:
The 4 buttons with a built-in LED, called "INPUTS", are used for selecting a source.
When a source is selected, it is immediately switched to the PREVIEW output.
The 4 "OUTPUT" buttons are used for switching the previously selected input to the
required output.
If MODE AFV (Audio Follows Video) is enabled, the video and audio input signals are
switched to the preview output and subsequently to the required output; if "only video" is
enabled, the switching applies only to the video.
This also applies to "only audio”.
The status of the machine, including the preview, is shown on the LED matrix, which is
installed on the unit front panel. 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, namely Audio Follows Video).
5.1.1 Switching time setup from keypad:
The TZM443 features the “through blank” switching mode. The switching time is user-
adjustable to permit the perfect matching with the destination device.
This important feature prevents annoying effects coming from LCDs when switching a
signal to their input.
Since every LCD has its own response time, the user can change the through blank
duration from 0.3 to 2 seconds to achieve optimal switching.
There are four settable times:
0.3 sec.; 0.5 sec.; 1 sec. and 2 sec.
In order to display and setup the through blank
switching time with the keypad, the MODE button
must be in LOCK position.
By doing so, the setup time will be displayed on
the LEDs of the keys associated with inputs 1, 2,
3, and 4 with the following meaning:
To set up a new switching time, it is necessary to hold down the required key for 2
seconds according to the time required.
The default value is 500 msec.

The switching time setup, performed through the keyboard, is valid for all outputs of the
matrix, including the preview output; whereas it is possible to set up a different time for
every single output via a command from the serial line.
In this case, the set time for output No. 1 will be displayed on the LEDs.
The display of the connections on the LED matrix will follow the actual switching on the
outputs; afterwards, the display of a switching command will be delayed for a period of
time equal to the switching time. PLEASE NOTE
Remember that switchings resulting from a
RECALL command do not occur "through blank"
5.2 Keypad Setups
By pressing a combination of keys, different commands and setups are possible for the
TZM443 unit. In addition, it is possible to store 3 machine status presets and to recall
them at a subsequent time.
It is also possible to store a default configuration so that the machine will start up with a
particular setup.
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
The 3 presets mentioned above are part of the 8 that can be recalled from the PC (as
explained in paragraphs 7.6 and 7.7).
Thus, we will have the possibility to save and recall:
3 configurations from the keypad
4 configurations from the IR remote control
8 configurations from the PC
PLEASE NOTE
Recalling a keypad preset, from the computer or from the
remote control, also sets up the same configuration as a restart
Mode for 2 sec. Machine status storage (one flash of the two MODE button LEDs
indicates that the information has been stored). When started up
again, the TZM443 will set up with the same status.
Subsequent preset recalls from the keypad or computer will change the default
configuration, thereby corresponding to the last recalled preset.

8.0 CONTROL FROM COMPUTER VIA RS485
A software in Windows, available on Elpro’s website www.elprovideolabs.com, is able to
control the TZM443 via RS232 or RS485
If the user wants to develop his own customized software, the same website offers
protocols to be implemented both for RS232 and RS485.
All functions of the TZM443 matrix can be controlled by sending or receiving hexadecimal
or ASCII character strings via a computer.
The transmission protocol is of the multipoint master/slave type: the TZM443s are the
slave machines, whereas the host which controls them is the master machine.
Up to 8 TZM443 units, identified by addresses 0 – 7, can be connected to the 485 Bus.
The serial connection features are:
8 data bits,
no parity,
1 stop bit
speed that can be set at 2400 or 9600 bauds,
The transmission speed, the address of the unit and the response time can be set via a
special control from the RS232.
The TZM443 response time is the time that should pass between the end of the reception
of the command and the beginning of the transmission of the response.
Such time allows the host to release the 485 bus and to get ready for the reception
without causing conflicts.
the following parameter defaults are automatically applied:
- speed = 9600 bit/sec
- unit address = 0 (30 hex)
- response time = 32 ms
Wait 150msec between one command and the other.

The protocol used requires all messages exchanged between the host and TZM443 to be between the
following command characters:
- commands from host to TZM443:
STX ADDR command ETX
- response of the TZM443 to host:
STX ADDR response ETX
The character STX corresponds to 02 hex,
The character ETX corresponds to 03 hex,
the field ADDR is the address of the TZM443: from 30 hex to 37 hex (namely from 0 to 7 in ASCII)
The contents of the fields command and response are the same as the commands previously indicated
for protocol RS232 with the exception of character CR (hex 0D) which, in this case, is skipped.
8.1 Managed Commands
The commands which are possible to send via RS485 are all those required for the RS232 with the
exception of the command “Set RS485 communication parameters”:
- video and audio switching commands.
- video switching command.
- audio switching command.
- status request
- creating a preset
- recall of a preset
- firmware release identification request.
- global mode request
- set through blank switching time
- through blank switching time request
- set preview output
- mute setup on preview output
Example: In this case, the video switching control will have the following format:
STX ADDR VXXYY ETX where: V is the character Hex 56
XX is the output (from 01 to 4)
YY is the video input (from 01 to 4)
The TZM443 matrix will respond:
STX ADDR ACK ETX where: ACK is the character Hex 06
if the control has been executed correctly
STX ADDR NACK ETX where: NAK is the character Hex 15
if it has found incorrect transmission or parameter errors.
Hence, the switching control of video input 2 on bus 4 for the TZM443 with address 2 will be as follows:
STX 2 V 04 02 ETX(in code Hex: 02 32 56 30 34 30 32 03)
The matrix will respond with:
STX 2 ACK ETX (in code Hex: 02 32 06 03)
or with:
STX 2 NACK ETX (in code Hex: 02 32 15 03)
