The SW221 3G provides simple 2 x 2 switching between two 3Gb/s, HD or SD signals, making it ideal for use either as an emergency transmission switch to avoid broken equipment or to manually bypass products requiring maintenance on a 24 hour station.

Where a single point of failure is involved you need something that you know will always work. Broadcasters choose the SW221 3G because of its functionality, its price and because they trust it for this critical task.

The SW221 3G is ideal for switching between the main and backup feeds of a television station, and offers independent control of the two outputs.

With manual switching there is the choice of switching between the two feeds either immediately or in the vertical blanking period, with the SW221 3G detecting the video standard and switching at the appropriate point to enable a cleaner switch.

The SW221 3G provides two outputs of the first switched signal, along with one output of the other – with the secondary signal output ideal for previewing both the main and the backup feeds.

An automatic switch away from a faulty source is triggered immediately on loss of input or invalid video, determined by loss of the sync word structure. A single format can be set as valid, allowing the SW221 3G to automatically switch away from inputs that are legal but not the correct format.

Switching back can either be automatic or by user intervention.

When set to automatic the board will switch back if the original input returns to a valid state, with a programmable delay ensuring that the previously faulty input remains good for the selected time period.

When set to user activated it will stay on the new selection until the routing is changed by the operator, or the new input becomes invalid.

The SW221 3G will save you rack space, with this 100mm x 266mm module fitting in Crystal Vision’s standard frames and allowing easy integration with any products from the range.

The inputs and outputs are accessed by using the RM53 and RM54 frame rear modules. The RM54 includes relay bypass protection on power failure or board removal, giving that extra layer of security and preventing signal loss.

SW221 3G’s flexible control options give you the choice of board edge switches, front and remote panels, SNMP, GPIs and PC software.

The SW221 3G is a product that broadcasters can rely on.
