1Introduction
he 3408 is an eight input, one output serial digital video/telecom switcher intended
for use with all composite and component serial digital video and telecom signals
between 139 and 360 Mbit/s. he switcher has been designed to fit in either the 1U
1051 or 3U 1050 Pro-Bel modular product rackframes. In the 1050 frame the module
occupies 30mm of rack space. It provides a solution for small ancillary or
monitoring matrices with the benefit of simple button per crosspoint control.
he architecture of the modules allow crosspoint outputs to be bussed together to
allow switchers above eight inputs to be built. In addition, the switcher may be
configured with other modules in the Pro-Bel range to form married multi-level
matrices.
An onboard rechargeable battery provides retention of crosspoint settings after
power loss.
Characteristics of the module are:
•easy expansion up to 64 inputs
•output regeneration (re-clocking)
•flexible control, with button per crosspoint or binary addressing
•black and burst reference input
•wide selection of data rates: serial digital video - 143, 177, 270 and 360Mbit/s,
DVB-ASI @ 270Mbit/s, telecom - 139 (PDH) and 155(SDH)
•crosspoint memory via battery backup
•front mounted crosspoint tally display
•compatible with Pro-Bel COSMOS status monitoring

408 8x1 digital video/telecom switcher

2Installation
he 8x1 digital video/telecom video switcher consists of a 3408 ICON module which
uses the 30mm K3408.3 rear connector. he rear connector occupies 30mm in a 3U
1050 ICON frame and one slot in the 1051 ICON frame.
For module and rear connector installation instructions please refer to the
appropriate ICON rackframe section of this manual.

2.2rosspoint control
onnecting button panels
Crosspoints may be selected by connecting a button panel (eg. Pro-Bel’s 8 button
6200 or 16 button 6202) to the control socket on the K3048.3 rear panel and setting
PL2 to ‘Button’ . Alternatively, custom button panels can be built using the following
wiring diagram.
he 3408 switcher has priority switching built in. If two keys are pressed
simultaneously, the higher numbered one will be selected. his feature allows ‘line
up’ to be performed quickly. o achieve this, one key must be held down and a
higher numbered key pushed and released. Each time the higher numbered key is
pushed and released that source will be selected, as long as the button is held down.
Once the button is released, the previous source is selected again.
wo 8x1 modules may be independently controlled from a 16 button panel, such as
the Pro-Bel 6202. his particular panel has two separate connectors to plug into the
control socket on each module, simplifying the installation. If the internal expansion
cables are fitted (see Source expansion), priority switching can be performed across
several modules. he highest priority module will always be the leftmost, viewed
from the front of the cards.
Using binary control
o use binary control instead of a button panel, PL2 must be set to ‘BIN’. Crosspoints
may be selected by binary addressing according to the table below, using 12V CMOS
levels using the Control socket on the rear connector.

Binary control signals can be generated by one 8x1 module and fed to another, to
create a master slave configuration. o achieve this, the lower expansion cable on
the front of the cards must be fitted, and all slave modules set to binary mode. he
master module can be set to button mode and conveniently driven from a button
panel.

3.2Setting the local/remote mode

monitoring system with SW1-4.
he yellow remote LED will illuminate when the remote mode is selected.
3.3onfiguring an 8x1 switcher
he method of crosspoint selection is set by PL2.
Configuration changes are accomplished by pulling the jumper (the shaded area
above) from its current position on the header pin block and moving it to the
alternate position on the same block. Normally, the jumper should make contact
with two pins

3.4Source expansion
Several 3408 cards can be linked to make larger switchers up to 64x1. Expansion
employs the front of card connectors together with the ribbon cable supplied with
the card. he output is always taken from the last downstream card.
Expansion to 40, 48, 56 and 64 x1 simply requires further modules added to the
expansion chain using the ribbon cables provided.

3.5Level expansion
It may be useful in some applications for one card to control the input selection of
other cards to create a multi-level switcher. his mode is called master/slave and
utilises the binary address interconnections.
he master card can be driven from a button panel and all the other cards by binary
addressing using only the lower expansion connectors PL8-PL9 on the front of the
card.
In this example of a synchronous three level audio switcher, both address and
control/video expansion bus connectors are used. It may be desirable to distribute a
vertical trigger signal from the first card (leftmost) in the expansion to ensure
switching during the correct line of a reference video field. his is why the vid/cntl
ribbon is used. However, the video expansion jumpers 10 and 11 must be OFF on all
cards.

4Trouble shooting
The green card edge POWER LED is not lit
•check the PSU indicator to confirm that there is power to the frame
•if necessary examine the fusible resistors RSF1, RSF2 protecting the card to see if
they have operated - turn the power off and wait for 30 seconds before restoring
the power
•if necessary, refer to the power supply trouble shooting guide in the appropriate
ICON rackframe manual section
There is no output signal
•ensure that the green card edge POWER LED is lit
•check that the inputs are connected to the rear panel and a valid signal is present
•verify that the correct channel is selected - the LED on the button panel should
show the same channel as the CHAN SEL LED on the front of the module
•check the output connection from the rear panel to the monitoring device and
the output cable
•ensure that the cable wiring and jumper link settings are correct for the
configuration used
The button panel will not select a different input
•ensure that the jumper PL2 is correctly set to ‘BU ON’ on all modules
•check that the expansion cables are correctly installed
•check that another, higher numbered, input is not permanently selected
The red error LED is lit (regenerator unlocked)
•check that SW1 and PL4 are set to the correct signal type and bit-rate
The output signal is corrupted
•check that the red error LED is not lit
•ensure all expansion cables are installed correctly

If the frame is equipped with a COSMOS controller card the following parameters will
be reported back to the COSMOS status monitoring system.
•module present
•input selected

•remote/local mode
•module power LED status
he following module parameters may be controlled through the status monitoring
system when remote operation is enabled:
•data rate selection
In addition, the module is programmed with the following information, which can be
read by the status monitoring controller:
•module type
•module bar code
•module issue no
