The HDS202 is designed for switching applications where
larger routers are not cost effective or do not offer the safety
measure of emergency switching. If inputs are co-timed, a
seamless changeover is achieved, making the HDS202
ideal for live applications. Both inputs are monitored and if one
fails, the output is automatically switched.

The automatic switching feature can overridden by the operator through external connection
to the GPI, a simple switch is also provided on the front of the card to give users a quick
method of switching between inputs. A tally output indicates when the switch has occurred.

The program path is maintained, even in the event of a power failure, through the inbuilt
bypass relay.

Inputs:
2 x High Definition Video to SMPTE 292M

Outputs:
3 x High Definition on line and 1 off line output to SMPTE 292M
In the event of power failure to the unit a passive bypass relay connects the
main input to the program output. This can also be activated by a switch on the
front of the card.

Control:
In ¡°Manual¡± switch mode a closing contact to ground on the GPI input causes a
switch to input B.
In ¡°Auto¡± switch mode the card will switch to input B when the video on input A
becomes invalid (loss or mis-aligned sync words for 8 fields). In Auto mode
switching can still be activated by the external GPI input.
A tally output is provided which indicates switch status.
On the 1U frame GPIs and tallies are wired to a 15 way high density ¡®D¡¯
connector and are included with the frame. On the 3U frame the -CB option is
required to provide the wiring of all card to two 25 way ¡®D¡¯ connectors.

Physical:
Eurocard size module for mounting in our 1U or 3U frames.
Power usage: 5W.

Frames:
Up to 6 modules will fit in a Microvideo 1U frame and 14 in a 3U frame.
They may be mixed with other Microvideo Series 200 boards in the same
frame.

Ordering:
HDS202 2x2 High Definition video emergency switch module.
EU-FRM1U 1U rack mounting frame for series 200 cards.
FL-FRM3U 3U rack mounting frame for series 200 cards.
-RP Redundant power supply (for both 1U and 3U frame, this option reduces
card capacity).
-CB Control Bus wiring for 3U frame.
