2Introduction

Thank you for purchasing a DEV 1953 Universal Switch Chassis. This user manual is

intended to familiarize you with the installation and operation of the product.

The DEV 1953 chassis for professional use can be equipped with modules with the

same or with different functionalities, to realize a switching solution for up to

16 channels. 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 1953 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!

2.1 Warranty

The product has a warranty against defects in material and workmanship for a

period of two years from the date of shipment.

During the warranty period DEV Systemtechnik will, at its option, either repair or

replace the product if it turns out to be defective.

For warranty, service, or repair, the product must be returned to DEV System-

technik. The customer has to pay shipping charges to DEV Systemtechnik and

DEV Systemtechnik will pay shipping charges to return the product to the customer.

However, the customer is obliged to pay all duties, all taxes, and all other additional

costs arising from the shipment of the product.

DEV Systemtechnik warrants that the software and firmware designated by

DEV Systemtechnik for use with the product will execute its programming

instructions if installed properly. DEV Systemtechnik does not warrant that the

operation of the product, software, or firmware will be uninterrupted or error-free.

2.2 Limitation of Warranty

The preceding warranty does not apply to defects resulting from:

improper site preparation or site maintenance;

improper or inadequate interfacing of the product;

unauthorized modification or misuse of the product;

the application of software supplied by the customer;

improper or inadequate maintenance of the product;

operation beyond the environmental conditions specified for the product.

2.3 Warnings

The following safety measures must be observed during all phases of operation,

service, and repair of the device. Failure to comply with the safety precautions or

warnings in this document violates safety standards of design, manufacturing, and

intended use of the device and may affect the built-in protections. DEV System-

technik shall not be liable for the user's failure to comply with these requirements.

Disconnect the device from any external power line before opening of the housing.

In any case, the device is to be opened by trained service staff, only.

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

(with Option 14: DC 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.

With applied Option 14, the device is supplied with DC voltage instead of AC mains.

In this case, do not connect the device to DC mains supply exceeding the

specifications for input voltage. For the DC supply wiring use cables with an

appropriate wire size. The pin assignment of the DC supply connector is stated in

chapter 7.

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

light that is capable to harm the human eye!

If no optical fiber is (to be) connected to an optical module, the optical con-

nector(s) have to be equipped with the appropriate protection cover(s).

Direct exposure to the beam is to be avoided, i.e. do not look into

unterminated optical ports or at fibers that connect to unknown sources.

3Product Description

With the DEV 1953, DEV Systemtechnik has developed a modular design principle

for a universal switch chassis. A variety of different switch modules is available that

can be installed easily in the 16 slots of the device. A selection of passive splitter

modules and of distribution amplifier modules for ASI/SDI signals is available 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 1953. 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 1953 (chapter 3.1.3) as well as the application of the TRAC

(stands for "Trap Receiver Action Controller") option (chapter 3.1.5).

3.1 Features and Options

3.1.1 Device Panel

Aside from the device panel -which is explained in the following- the product

provides the "Reset" push button on the CPU module (please refer to chapter 3.2.24)

for restarting the device, and the two LEDs on each power supply module

(chapter 3.2.25).

The device panel occupies most of the space at the front side of the chassis:

The mode push button (3) permits the change of the operation mode (chapter 5.1)

at the device. By pressing and holding the push button for ~3 seconds the status of

the LEDs advances, i.e. always only one of the operation mode LEDs "Remote" (4),

"Local" (5), or "Auto" (6) is on.

The second functionality of the mode push button is the event acknowledgment:

If there are pending and not acknowledged event(s), this is indicated via continuous

alternate blinking of all channel LEDs. To acknowledge the event(s) (i.e. to stop the

blinking of the LEDs) at the device, 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:

A short operation of the mode push button acknowledges the event(s) (stops

the blinking of the LEDs). After that, the operation mode can be altered as

described above.
