2Introduction
Thank you for purchasing a DEV 1951 Universal Switch Chassis. This user manual is
intended to familiarize you with the installation and operation of the product.
The DEV 1951 chassis for professional use can be equipped with one or two switch
modules with the same or different functionalities, thus realizing a single or dual
channel switching solution. There is a large selection of switch modules for
different applications; in addition, there are available some modules without
switching functionality that can be applied to the DEV 1951 chassis as well.
DEV Systemtechnik GmbH declares that this equipment meets all relevant
standards and rules. The unit carries a CE mark.
Please read all instructions before installation or usage of the product!

Environmental Conditions
The device is designed for indoor use and for an ambient temperature range.
Mechanical Integration
It is not permitted to fix the chassis on the rack mount flanges, only. Balanced
weight distribution of the chassis has to be ensured by placing it on a solid surface
or by using rack rails.
Sufficient airflow through the chassis must be ensured to achieve best cooling
results. Do not block or obstruct the airflow through the chassis at the front and at
the rear side, e.g. by placing large components close to the rear side.
Grounding, AC Connection, Cables
To minimize shock hazard the device must be connected to an electrical ground via
a ground wire, please refer to chapter 4.2.2.
For the AC connection, the device must be connected to the AC power supply
mains through two power cables with three conductors and with the ground wire
firmly connected to an electrical ground (safety ground) at the power outlet. Any
interruption of the protective ground conductor will cause a potential shock hazard
that might cause personal injury.
Risk of electrical shock and energy hazard:
Disconnecting a single power supply line only does not interrupt the AC supply of
the device. To isolate the device completely, disconnect both power supply lines.
Do not connect the device to AC mains supply exceeding the specifications for input
voltage and frequency. The recommended AC cables to be applied are standard
high temperature power cables with type IEC 60320-C13 appliance plug appro-
priately rated to the conditions of the country where the device is operated.
Laser Safety (applies if equipped with Optical Switch Modules DEV 7462, DEV 7463)
Safety of Laser Products
DEV Systemtechnik recommends following the governing standard of the
country where the product is operated to assure regulatory compliance and to
provide the necessary safety programs to protect the operators and other
persons who get in contact with the product.
It is recommended to power down the product while working on the optical
fiber wiring.
The optical modules installed in the product operate with light at a non-visible
wavelength. Highest caution has to be taken, since the modules may carry laser

3Product Description
With the DEV 1951, DEV Systemtechnik has developed a modular design principle
for a universal dual channel switch chassis. A variety of different switch modules is
available that can be installed in the two slots of the device. A selection of passive
splitter modules and of distribution amplifier modules for ASI/SDI signals is avail-
able as well. Please refer to chapter 3.2 for the description of the single modules.
A device panel (chapter 3.1.1) permits the monitoring and the local control of the
DEV 1951. Some other methods for the control and for the surveillance of the
device are provided (chapter 3.1.2). The application of sensing switch modules and
of digital signal switch modules enables additional autonomous switching
capabilities of the DEV 1951 (chapter 3.1.3) as well as the application of the TRAC
(stands for "Trap Receiver Action Controller") option (chapter 3.1.4).
3.1 Features and Options
3.1.1 Device Panel
The DEV 1951 provides a device panel at the front side of the chassis. A mode push
button and three yellow LEDs are located at the left side:
Universal Switch Chassis
Local
Rem ote
DEV 1951
Auto
1 2 3 4
The mode push button (1) permits the change of the operation mode (please refer
to chapter 5.1) at the device. By pressing and holding the button for ~3 seconds the
status of the LEDs advances, i.e. always only one of the operation mode LEDs
"Auto" (2), "Local" (3), or "Remote" (4) is on.
Note:
Products with the preceding version of the device panel are providing a "Local"
push button (instead of the mode push button) and a single "Remote" LED (i.e.
there is no explicit "Local" or "Auto" LED). The behavior of the push button and
the LED differs: The "Local" push button realizes the same functionality as the
mode push button but the device can be toggled between Local Mode ("Remote"
LED off) and Remote Mode or Auto Mode ("Remote" LED on) and vice versa,
only. Switching from Local Mode via the "Local" push button toggles to the
preceding mode (Remote Mode or Auto Mode) which was activated before the
device had been switched to Local Mode. The explicit activation of Remote
Mode or of Auto Mode is performed via Web Interface (chapter 5.5.2), or via
SNMP (chapter 5.9.4.3.1), or via Sandar Prosan protocol (chapter 5.6.3.6).
Moreover, even older revisions of the DEV 1951 additionally provide a "Reset"
push button located left to the "Remote" LED and to the "Local" push button. This
"Reset" button is not supported by the firmware of the device. Please do not
operate the button it might have an impact on the behavior of the installed
switch modules!

The second functionality of the mode (or "Local") push button is the event
acknowledgment: If there are pending and not acknowledged event(s), this is
indicated –in addition to the alarm connector, please refer to chapter 6.1.2- at the
device panel via continuous alternate blinking of all channel LEDs, the "Individual"
LED, and the "Simultaneous" LED (see below). To acknowledge the event(s) (i.e. to stop
the event indication and thus the blinking of the LEDs at the device panel), the
mode push button is to be operated. Thus, three scenarios for the behavior of the
mode push button are to be considered:
1. There are no pending and not acknowledged event(s):
In this case, the operation mode can be altered as described above.
2. There are pending and not acknowledged event(s) in Local Mode:
In this case, a short operation of the push button acknowledges the event(s).
After that, the operation mode can be altered as described above.
3. Pending and not acknowledged event(s) in Remote Mode (or Auto Mode):
In this case, a short operation of the push button acknowledges the event(s)
and switches the device to Local Mode. After that, the operation mode can be
altered as described above.
Note:
The type of event causing the event indication can be identified via Web
Interface or via remote interface, only.
If an event is not acknowledged and if the event disappears (e.g. a detected
missing AC line is working again), the event indication will stop automatically (if
it is the sole event).
The event indication cannot be stopped if no switch (or distribution amplifier)
module is installed or detected within the device.
In the middle of the device panel, the following elements are located:
the channel push buttons and the green channel LEDs (5& 7) and
the switching mode push button and the yellow LEDs (6) for the Simulta-
neous/Individual switching mode functionality (please refer to chapter 5.1.4):
In A In B
Ch 1
Individual
Simultaneous
567
In A In B
Ch 2
With the channel push buttons labeled "Ch 1" and "Ch 2", one of the two (input) ports
(primary (input) port "In A" or secondary (input) port "In B") of a switch module can
be switched to the common (output) port in Local Mode (!). The (input) port that is
currently active is indicated via the related green channel LED.
To alter the routing of a single switch module via the related channel push button
make sure that the device is in Local Mode and that the "Individual" LED is lit. After
the operation of the desired channel push button, the LED display will indicate the
altered switching position as a receipt.

If the "Simultaneous" LED is lit (for the preconditions to activate Simultaneous
switching mode please refer to chapter 5.1.4), any of the two channel push buttons
can be operated to initiate the switching of the two installed switch modules.
Note:
If the device is equipped with a single switch module only, the channel push
button of the empty slot will not work. In addition, the Simultaneous switching
mode is not available.
Three LEDs located at the device panel on the right are signalizing the power supply
operating status of the device:
Power Supply 1
Power Supply 2
Failure
8 9 10
"Power Supply 1" LED ((8), green) and "Power Supply 2" LED ((9), green):
The related power supply unit provides secondary voltage if this LED is on.
"Failure" LED ((10), red): This LED is on if either power supply unit does not
deliver any secondary voltage. The reason for this can be a defective power
supply, a defective primary protection fuse, or a missing primary voltage.
3.1.2 Communication Features
In addition to the device panel there are provided some options for the monitoring
and control of the product:
The standard digital interface of the DEV 1951 features basic remote switching
functionality permitting the control of the device, e.g. via a PLC (Programmable
Logic Control), please refer to chapter 5.4.
The Web Interface (chapter 5.5) provides features for checking the health status
and for changing the setup of the device; it enables full control in terms of
switching and in terms of setting up specific parameters. Additionally, the features
Time Based Switching and TRAC (if installed), and -for devices with installed sensing
switch modules- the recording functionality are accessible.
The implementation of SNMP (Simple Network Management Protocol) via the
Ethernet interface is intended to serve as the standard for remote monitoring and
control of the device (chapter 5.9).
In addition, a Communication Protocol Handler (CPH) is implemented which
enables the use of one of the following remote protocols with different monitoring
and control capabilities:
Sandar Prosan protocol via serial interface (chapter 5.6);
Leitch protocol via serial interface and via Ethernet interface (chapter 5.7); and
QEC protocol via serial interface and via Ethernet interface (chapter 5.8).
The installation of sensing switch modules and of digital signal switch modules
enables the autonomous switching capability (chapter 3.1.3) of the device based on
the signal quality. Moreover, the TRAC option (chapter 3.1.4) permits a remote
device to control the switching of the DEV 1951.

3.1.3 Autonomous Switching and Options
Among the broad choice of other switch modules, the DEV 1951 can be equipped
with one or two sensing switch modules or with one or two digital signal switch
modules; a mix of both types of switch modules is supported as well.
The sensing switch modules (and the digital signal switch modules) are special since
they permit the device to switch autonomously (please refer to chapter 5.1.3)
based on the RF level information (and on the digital signal quality information,
respectively) at both input ports of the module.
By default, the DEV 1951 provides autonomous switching capability from the
primary to the secondary input port(s).
With Option 22, the DEV 1951 is delivered with the main backup swap feature, i.e.
the autonomous switching works in both directions instead of switching from the
primary to the secondary input port(s), only.
With Option 28 the DEV 1951 is delivered with the automatic switch back feature
which permits the autonomous switching in both directions as well, but with an
adjustable hysteresis (for sensing switch modules) or with an adjustable delay (for
digital signal switch modules) when switching back from the secondary to the
primary input port(s).
The Web Interface enables the adjustment of the RF threshold levels for each input
port of a sensing switch module and enables the modification of settings for the
automatic switch back option.
3.1.4 TRAC Option
The product can be equipped with the TRAC (stands for Trap Receiver Action
Controller) option (Option 37), which permits the remote controlled switching of
the product based on SNMP traps, or based on the availability or on the absence of
a remote device (IP Monitoring). For more details, please refer to chapter 5.5.7.3.4.
