- Stock: 4
- Code: BS18000
- Model: DEV 1820/8
DEV Systemtechnik Redundancy Switches DEV 1820/8. The common base of the DEV 1x20/xx and the DEV 1530/xx is a 19” 3 RU chassis prepared for the integration of various switch modules. The field of application is indicated by the different model numbers, please refer to the next page, where the functionality of the different switch modules is explained. The instruments of this series are available with a different number of switch modules installed, indicated by “/xx” which can be either /4, /8, /12, or /16.
There are various possibilities to operate the instrument: First, there is the operation via the push buttons on the instrument thus enabling the local control. The default Basic Web Interface provides features for checking the health status of the instrument and for changing the basic setup of the instrument. The instrument can be equipped with the Web Interface Option (Option 78), which additionally permits the full control of the instrument, in terms of switching and setting up specific parameters. Additionally, the implementation of protocols (Sandar Prosan, Leitch, SNMP) provides the remote control and surveillance of the instrument.
Multi Channel ASI Redundancy Switch, 75 Ohm BNC
ASI Redundancy Switch
Module
For ASI signal applications in 75 Ohm with BNC
connectors.
The module combines a 2:1 input selection and
a 1:3 active distribution amplifier for ASI signals.
One of two inputs feeds the three parallel
outputs.
The signal transmission of DC is blocked.
