DEV 1951 Universal Switch Chassis

DEV 1951 UNIVERSAL 1 RU SWITCH CHASSIS The DEV 1951 is a modular dual channel universal switch chassis offering a variety of switching in 1 RU. The chassis contains two slots, which can be populated with: DPST, transfer, Ethernet, ASI, E1/T1, or optical switches. A variety of the available switch modules can be installed in the two slots of the device. A selection of passive splitter modules and distribution amplifier modules for ASI/SDI signals are also available. Frequencies supported by the DEV 1951 include: ASI/SD/HD/3G-SDI, Ethernet, E1/T1, L-Band, and broadband. Monitor and control options include SNMP and a web browser via both serial and Ethernet ports.

A mode push button and three status LEDs are located at the left side of the panel. These buttons permit operational mode of the device to be changed. By pressing and holding the button for about 3 seconds, the status of the LEDs advances from "Auto" to "Local" to "Remote".   The second functionality of the mode push button is event acknowledgment. Pending and unacknowledged event(s) are indicated by the continuous alternate blinking of all channel LEDs, the "Individual" LED, and the "Simultaneous" LED. To acknowledge an event, the mode push button must be pressed according to three possible scenarios. The type of event causing the event indication can be identified via Web Interface or via the remote interface.  In the middle of the device panel are located the channel push buttons, the green channel LED indicators and the switching mode push button and yellow LEDs. With the channel push buttons labeled "Ch 1" and "Ch 2", the primary or secondary input port of a switch module can be switched to the common output port in Local Mode. The currently active input is indicated via a related green channel LED.   If the "Simultaneous" LED is lit, any of the two channel push buttons can be operated to initiate the switching of the both installed switch modules.    Three LEDs located at the right side of the control panel indicate the operational status of the redundant power supplies.  Remote Control In addition to front panel controls, there are also options for the remote 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). The Web Interface 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.  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. 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 Leitch protocol via serial interface and via Ethernet interface QEC protocol via serial interface and via Ethernet interface  The installation of sensing switch modules and of digital signal switch modules enables the autonomous switching capability of the device based on the signal quality. Moreover, the TRAC ("Trap Receiver Action Controller") option permits a remote device to control the switching of the DEV 1951.   Product Documents & Videos Spec Sheet Click to Download User Manual Click to Download
