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 ad isable 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. EMOTE 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. EMOTE
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 GB 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 mu ually exclusive. Priori y is as follows:

controlled as regards all the functions described, simply by
sending a hexadecimal character
Transmission is RS 232, 8 bi s,
1 s op bi , no pari y.
Baud ra e is 9600.
The character must be sent to pin #12 of the sub-D 25 v. f.

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.
