Introduction
Overview
The FSR DV-HDSS-41-TX is an advanced four-input, multi-format converter,
switcher, scaler and extender with built in 4K UHD scaling, in a compact 1RU
half-rack enclosure. It offers two HDMI inputs, one DisplayPort input and one
VGA input with Stereo Audio; Scaled HDMI with EDID controlled HDBaseT
mirrored output to allow signal extension over CatX cable to reach a remote
display, or additional HDBaseT signal management system. Additionally, one
balanced stereo audio de-embedded output generated from the scaled HDMI
video output.
It supports four control options, two auto switching options, push buttons on
the front panel, contact closures with lamp feedback and API. It also has
built-in CEC control that can automatically turn a CEC enabled display
on/standby by auto-detecting input signal status. The built in 4k@30Hz scaler
on the HDMI output is controlled by a rotary switch that allows seamless
switching without black to enhance presentations by eliminating distractions
during switching.
It simplifies classroom and small office system integration, for installation
beneath conference tables and in lecterns, to provide localized presentation
switching support.

Connection and Installation
1. Using only good quality VGA/DP/HDMI cables firmly connect a 4K or HD
source device to the VGA/DP/HDMI input ports of the switcher.
2. Firmly connect HDMI OUT of the Switcher to HDMI IN of 4K or HD display
devices ensuring both source and display devices are compatible and
correctly configured to output and accept the required signal resolution.
3. Connect a good quality, well-terminated CAT-6A shielded cable between
the HDBaseT OUT of the Transmitter switcher to the HDBT IN Input of an
HDBaseT Receiver.
4. Insert the included power supply, Check the front panel power LED to
indicate the switcher is ready to use.
5. Connect the CONTACT IN, TALLY OUT and SINK via the Male Connector
included.
Note:
External momentary contact closure referenced to GND should
be >1mA but <5 mA.
Open circuit voltage 3.3~12 volts will be acceptable.
Protected against application of external voltages is in the range of
+/- 24V W.R.T. GND.
Minimum contact closure time is 50 ms (It is able to ensure
detection of external closure).
LED output voltage is +12 volts (Nominal, 10~13 volts is acceptable),
maximum output current is 100 mA and when active it should be
short circuit protected.
6. Switch between sources using the switch buttons in front panel, via
CONTACT IN control, or RS232.
7. Switcher can be directly connected to FSR HV-T6 Table Box following
wiring chart below.

Operation
Input Select
The input source can be selected via 2 different types of Auto Mode, where the
unit detects the connection, disconnection and signal presents or through the
front panel push button, RS232 serial command or momentary contact
closures.
When pressing the front panel switch the unit will step though the active inputs
in the following order: VGA->DP->HDMI1->HDMI2. When direct access to an
input is requested via RS232 or a contact input the unit will switch to that input
only if it as an active signal present. If the requested source is not active the
LED indicator will flash twice to indicate the source is not active and will not
switch.
To enable Auto-Mode Dip Switch Pin 2 should be switch UP. The unit is
programmed with 2 Auto Mode operation options; Priority and Last Connected.
The unit is shipped from the factory in the priority mode. The Auto Mode type
can be changed via a serial API command.
Auto Mode 1 (priority mode): VGA->DP->HDMI1->HDMI2
1. When power is applied to the switcher it will default to the VGA channel
unless there is another active source connected. If multiple sources are
already connected it will auto switch to the active source with the highest
priority.
2. When a new source is connected the switcher will auto switch depending
on the priority of the input signals.
3. When a currently selected source is removed the unit will auto switch to
the next lower priority input.
4. Manual and API switching is also valid in the Priority Mode. The front
panel button will switch through the active sources. Any switch command
via the Contact Closures inputs or API commands will be performed on

inputs with active sources only. If the selected source is not active the
LED indicator will flash twice to indicate the source is not active and will
not switch.
Auto Mode 2 (Last Connected):
1. When power is applied to the switcher it will default to the VGAchannel. If
multiple active sources are present at power up the unit will auto-switch
to the input with the highest priority.
2. When any new active source is connected the unit will auto switch to this
source.
3. When a currently selected source is removed the unit will auto switch to
the active source with highest priority, or remain on the current input if no
any active sources are present.
4. Manual and API switching is also valid in the Last Connected Mode. The
front panel button will switch through the active sources. Any switch
command via the Contact Closures inputs or API commands will be
performed on inputs with active sources only. If the selected source is not
active the LED indicator will flash twice to indicate the source is not active
and will not switch.
CEC Display Control
Consumer Electronics Control (CEC) is an HDMI feature designed to allow the
user to control any CEC-enabled device that is connected via HDMI. CEC
allows for CEC-enabled devices to be controlled without user intervention.
The switcher generates CEC commands to turn on or off the display(s)
connected to the HDMI and HDBT outputs. When the option for CEC is
enabled by setting Dip Switch pin 3 UP the switcher will send out a Power On
command when any device with a valid video signal is detected. The unit will
also send out a Power Off or Standby command when no valid video signals
are present for 2 minutes (default). The Power Off Timer can be changed to
any time between 1 minute and 30 minutes via a serial API command.

CEC commands can also be generated by depressing the Display On, Off
buttons on the front of the unit, by a remote key switch connected to the rear
terminal or by a serial API command to the unit.
Audio Controls
Separate volume and mute audio controls are available for the HDMI and
Analog Audio outputs via serial API commands. There are no audio controls
available on the HDBT output. When controlling the volume setting, serial
commands should be sent 500 ms. apart.
API Control
See FSR LIT1628 API manual for serial commands.
API commands are sent to the unit on the RS232 port marked "Control". The
second RS232 port is used to send serial commands to the HDBT receiver
only. The two serial ports can be jumped for control surfaces originating at the
end of the HDBT output by connecting Tx to Rx and Rx to Tx.
The RS232 port settings are:
1. Baud Rate –57600
2. Data Bits –8 bits
3. Parity –None
4. Stop Bits –1 bit
5. Flow Control –None
Note: The data format is ASCII.
