TZW803+ CONNECTION – 6 SOURCES 1 DESTINATION

2.0 POWER SUPPLY

The TZW803+ unit must be powered at 230 Vac 50Hz using the cable provided.
The cable must be fitted in the related panel plug on the left at the back of the unit.
The panel plug is equipped with a fuse-holder for 5X20 fuses. In the event of fuse
burnout, the replacement fuse must be of the same value, as specified on the back of the
unit (T 0.5A).

ATTENTION

All operations must be performed by specialized personnel

who must be made aware of electric shock hazards.

In some countries the current plug must be adapted to comply with local standard types.
Wires can be identified according to the following code:

-Brown PHASE (Marked with the letter L, may be red)

-Blue NEUTRAL (Marked with the letter N, may be black )

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

ATTENTION

Grounding is compulsory

The TZW803+ can be ordered for powering at 115Vac 60Hz.
The setting is made in factory and cannot be modified by the customer.

3.0 SETTINGS

The TZW 803+ switcher has a set of 6 dip-switches, accessible from the back of the unit,
that can be used to set and customize the unit. Five dip-switches are used to set
CASCADE functioning while the sixth enables or not the external IR remote control.
In pos. ON, default factory-set, it enables the IR remote control.

Refer to chapter 9.0 for a description of the settings.

4.0 INSTALLATION

a) Make sure that the switch on the back of the TZW803+ is set to OFF (O). Power the
device as indicated in chapter 2.0.

b) Connect the 8 sources to the sub-D 15 p. f. HD connectors with good quality VGA m/m

cables.

c) Connect the destination to the sub-D 15 p. f. HD conn. with a VGA cable with a length
of not more than 20 meters.

ATTENTION

For more than 20mt cables, it is advisable to insert

an Elpro INBOX/4 type booster

Use of Elpro cables is recommended in order to exploit

the characteristics of the compensation circuit to the full.

d) Connect the stereo audio in output from the 8 sources to the 8 RCA sockets ( AUDIO IN).

e) Tap the stereo audio in output from the RCA socket (AUDIO OUT) and / or from the
balanced audio output (BALANCED) and connect it to a sound amplification and
broadcast system.

f) Set the switch on the back of the unit to ON (I). Check that the built-in led of key 1 on
the front of the unit switches on.

5.0 LOCAL CONTROL

The TZW803+ switcher can be controlled using
the 8 keys on the front panel of the unit.

Switching on of the built-in led of the button
indicates which source is switched to the output.

At power-on, source 1 is switched automatically.

6.0 CONTROL BY DRY CONTACTS AND TALLY

The TZW803+ is controlled using 8 dry contacts connected to the sub-D 25 v.f. REMOTE
connector on the back of the machine.
Eight external signals are provided to light on the 8 tally leds connected as indicated in
the figure below.

7.0 ANCILLARY FUNCTIONS

The TZW803+ switcher features three ancillary functions that are activated with 3 dry
contacts connected to the sub-D 25 v. f. REMOTE connector on the back of the machine.
The function remains active as long as the related pin is at ground (pin 25).

7.1 AUTOSEQUENCING
All 8 sources are switched on the output at a rate of 4 or 10 seconds each.
The time of 4 or 10 seconds is established by pin 22 (TIME) of the sub-D 25 v. f. REMOTE
conn. on the back of the machine.
Contact open is for 4 sec. time
If an input is selected during autosequencing (using the keyboard, remote control or PC),
the input selected is connected and the autosequencing function restarts from that input.

7.2 AUTOSWITCHING
The active source is routed on the VGA/XGA output.
If more than one source is active, source 1 has the highest priority followed by source 2
and so on.
If an input is selected during autoswitching (using the keyboard, remote control or PC),
the input selected is connected and the autoswitching function is interrupted.

7.3 RGB MUTE
No source is switched on the output.
This capability is particularly useful when the images to be displayed on the computer are
to be prepared between one switching and the next.

ATTENTION

AUTOSEQUENCING, AUTOSWITCHING and RGB MUTE

are mutually exclusive. Priority is as follows:

RGB MUTE
AUTOSWITCHING
AUTOSEQUENCING

With the CASCADE option active, the three ancillary functions

controlled by dry contacts are excluded.

However, Autoswitching and Mute can be controlled from the computer.

8.0 COMPUTER CONTROL

The TZW803+ switcher can be computer
controlled as regards all the functions described, simply by
sending a hexadecimal character

Transmission is RS 232, 8 bits,
1 stop bit , no parity.
Baud rate is 9600.

The character must be sent to pin #12 of the sub-D 25 v. f.
REMOTE conn. connected on the back of the machine.
The ground is pin #25.

In CASCADE functioning, the source to be switched on the output can be selected using

the built-in keyboard of each unit or using the computer.

ATTENTION

In CASCADE functioning, pins 12 (RS232) and 25 (GND) of the

REMOTE connectors must be joined together and connected to the

transmitted signal of the host computer

9.0 CASCADE OPTION AND SETTINGS

The TZW803+ switcher features a CASCADE option that permits connection in series of
4 units to establish a 29x1 selector.

ATTENTION

In the CASCADE connection, band and technical

characteristics are no longer guaranteed.

In the case of CASCADE connection, the output of the first TZW803+ must be connected
to input 1 of the second TZW803+ and so on.
Using cables terminated with RCA plugs, connect together the LINK connectors present
on the back of the unit.

CASCADE functioning is activated by setting a switch that is accessible from the back of
the unit as indicated in the figure below (ENABLE CASCADE).
Each unit must also be customized according to its position in the chain with the setting of
another switch as indicated in the figure below.

ATTENTION

With the CASCADE option active, the three ancillary functions are

excluded except for RGB MUTE and computer-controlled AUTOSWITCHING.

ATTENTION

The last dip-

switch (pos.

6), if set to

OFF, makes

it possible to

disable

reception of

the
commands
from the IR

remote

control.
