1.0 OVERVIEW
Thank you for choosing our product. Check the contents of the packaging. It
contains:
The DVIDEC100 unit routes DVI-D video signals present on the four input channels
to a DVI-D output and to a high resolution RGB output on which it is possible to
select resolution from SVGA to SXGA. The Y,Cb, Cr format progressive from 480p
to 1080i is also available.
The possibility of selecting between four (or more in the case of cascade) input
signals, each with associated audio, makes the DVIDEC100 very useful in
presentation environments where several information sources must be displayed
on a single device. Conversion into RGB format makes it possible to work with DVI
quality on VGA cables overcoming the restrictions imposed by the length of the DVI
cables. A special circuit guarantees EDID connection towards the destination even
with source not selected, preventing switch-off of the source.
The DVIDEC100 unit performs switching with blanking on the DVI output and
seamless switching with fading on the RGB output. This solution makes it possible
to avoid the troublesome effects of LCD devices on switching of a signal on their
input.

9.0 CASCADE
Compatibly with source signal quality, several DVISEL403 switchers followed by a
DVIDEC100 can be connected in cascade to obtain a switcher of up to a maximum
of 13 inputs. A VGA switcher, type TZW403/803 can be inserted after the
DVIDEC100: in this way, a mixed DVI+VGA switcher is obtained using the VGA
output of the last TZW403/803 of the cascade.
The output of each unit must always be connected to input 1 of the next unit. The
last unit will be connected to the destination. Synchronization between the units is
assured connecting the RCA connectors called LINK located on the back using a
terminated cable. Cascade type functioning is activated operating on the 6-pin dip-
switch on the back. Make the following settings:
- Dip 1=ON enabling of cascade mode
- Dip 6=ON compatibility with VGA switcher type TZW/R (only for DVIDEC100)
=OFF only DVISEL403 and/or DVIDEC100 in cascade
- Dip 2=ON and 3, 4, 5=OFF 1st machine of the cascade (inputs 1÷4)
- Dip 3=ON and 2, 4, 5=OFF 2nd machine of the cascade (inputs 5÷7)
- Dip 4=ON and 2, 3, 5=OFF 3rd machine of the cascade (inputs 8÷10)
- Dip 5=ON and 2, 3, 4=OFF 4th machine of the cascade (inputs 11÷13)
To control the entire cascade via RS232, connect the serial link of the PC to the RS232
connector of the 1st machine of the cascade (inputs 1÷4)
2.0 POWER SUPPLY
The DVIDEC100 unit must be powered with an ac voltage of 90÷240V 50/60Hz
using the cable provided. The plug of the cable must be inserted in the related
panel plug on the left of the back of the unit.
The panel plug is fitted with a 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 .
All operations must be carried out by qualified personnel only
who must be informed of the risks of electric shock
In some countries, the plug of the cable must be adapted to align this local standard types.

9.0 CASCADE
Compatibly with source signal quality, several DVISEL403 switchers followed by a
DVIDEC100 can be connected in cascade to obtain a switcher of up to a maximum
of 13 inputs. A VGA switcher, type TZW403/803 can be inserted after the
DVIDEC100: in this way, a mixed DVI+VGA switcher is obtained using the VGA
output of the last TZW403/803 of the cascade.
The output of each unit must always be connected to input 1 of the next unit. The
last unit will be connected to the destination. Synchronization between the units is
assured connecting the RCA connectors called LINK located on the back using a
terminated cable. Cascade type functioning is activated operating on the 6-pin dip-
switch on the back. Make the following settings:
- Dip 1=ON enabling of cascade mode
- Dip 6=ON compatibility with VGA switcher type TZW/R (only for DVIDEC100)
=OFF only DVISEL403 and/or DVIDEC100 in cascade
- Dip 2=ON and 3, 4, 5=OFF 1st machine of the cascade (inputs 1÷4)
- Dip 3=ON and 2, 4, 5=OFF 2nd machine of the cascade (inputs 5÷7)
- Dip 4=ON and 2, 3, 5=OFF 3rd machine of the cascade (inputs 8÷10)
- Dip 5=ON and 2, 3, 4=OFF 4th machine of the cascade (inputs 11÷13)
ATTENTION
Switch ON all the units simultaneously or from the last to the 1° in sequence
To control the entire cascade via RS232, connect the serial link of the PC to the RS232
connector of the 1st machine of the cascade (inputs 1÷4)
2.0 POWER SUPPLY
The DVIDEC100 unit must be powered with an ac voltage of 90÷240V 50/60Hz
using the cable provided. The plug of the cable must be inserted in the related

1.0 OVERVIEW
Thank you for choosing our product. Check the contents of the packaging. It
contains:
The DVIDEC100 unit routes DVI-D video signals present on the four input channels
to a DVI-D output and to a high resolution RGB output on which it is possible to
select resolution from SVGA to SXGA. The Y,Cb, Cr format progressive from 480p
to 1080i is also available.
The possibility of selecting between four (or more in the case of cascade) input
signals, each with associated audio, makes the DVIDEC100 very useful in
presentation environments where several information sources must be displayed
on a single device. Conversion into RGB format makes it possible to work with DVI
quality on VGA cables overcoming the restrictions imposed by the length of the DVI
cables. A special circuit guarantees EDID connection towards the destination even
with source not selected, preventing switch-off of the source.
The DVIDEC100 unit performs switching with blanking on the DVI output and
seamless switching with fading on the RGB output. This solution makes it possible
to avoid the troublesome effects of LCD devices on switching of a signal on their
input.
