Title: HD Digital Video A/B Switch
Category: Digital Products
Industry: TV/Radio Broadcast, CATV Cable Industry,
The DVS772HD HD/SDI DIGITAL VIDEO SWITCH is a high isolation high frequency remote control A/B switch used to control the direction of digital signals such as high definition SDI signals or any digital signal with a bit rate as high as 1.485 Gbits.
The switch has two inputs and one output in an A/B configuration. The switching function is controlled by an external switch contact, RS232, or TTL type signal. It also has the ability to sense signal loss on the A channel and automatically switch to the B channel. This feature is used when automatic transfer to a back up alternate channel is desired.
The unit comes equipped with a front panel selector switch. The operator can select the data switch to Channel A, Channel B, or Remote operation. When the front panel switch is in the Remote operation position, the unit is controlled by an external input signal or by signal loss on the A Channel if selected. Normal, Inverted, and Toggle control is field programmable. There is a relay output to report the position of the A/B switch for remote telemetry or to control other equipment.
The unit has BNC female connectors for the data inputs and output and a removable screw terminal connector for the power and control signals. The 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 included side-mounting bracket.
