Title: Data A/B Switch
Category: Digital Products
Industry:TV/Radio Broadcast, CATV Cable Industry,
The DVS702 DIGITAL VIDEO SWITCH is a 2X1 A/B relay switching system that is controlled by an external contact closure or the front panel switch. This device is a Standard Definition “SD” Broadcast quality Video Relay switch that can carry NTSC, PAL, or HD-TVI video signals.
If a power failure occurs the unit will automatically switch to the “A” channel position. This is a relay type A/B switch with no amplifiers to degrade the data signal.
The unit can be used to engage a hot standby source by an external contact closure from a control system. This system will maintain your digital video integrity and reduce trouble calls. It will also serve as a slave relay where unattended video switching must occur if used with a Digital Video Switch (DVS772). For automatic video loss indication and switching all in one package, order the DVS772.
Also included is a front panel LED which indicates the status of the video switch. The front panel switch can be used to manually control the switch. Standard BNC connectors are used for the data inputs and output, and a plug-in style removable screw terminal connector is used for the power and control.
This switch is housed in a sturdy aluminum die cast box which is completely RF shielded. The box can be mounted in the front or rear of your rack with the standard mounting bracket.
