SVD 5812
3G-SDI 2 Channel Changeover Switch
The SVD 5812 is a 2 channel changeover switch which can be automatically triggered when an input fails or manually triggered. Fully compatible with SDI / DVB-ASI and SMPTE 310 signals up to 3Gbits/s. This module is ideally suited for demanding multi-format broadcast and professional video applications.
In re-clocked mode the module will auto-detect the connected video standard. When set to non re-clocked mode the module will transparently pass data from 15Mbit/s to 3Gbit/s.
The switch can be configured to switch manually from a external GPI input trigger or from the control system GUI. When configured for emergency switching the module will automatically switch when a designated input fails. This can be set to latch permanently or switch back automatically when main input returns. A GPO output trigger is provided when the emergency switch operates.
Version available which adds a mechanical relay which will connect inputs to outputs in the event of a power failure. [SVD 5812 R]
Local control capability is provided via the integrated dip switch. Remote control, status monitoring and error reporting is possible when using the LynxCentraal control system.
