1 Introduction
The SW222 is a 10-bit 2x2 Serial Digital switch. Each of two serial digital inputs can be
switched to either or both of two outputs. Switching can be controlled separately or
together, either from the board or from remote inputs.

SW222 SDI 2 x 2 Switch
The unit can be configured to switch automatically on input failure if required. Local and
remote indications of input status and switch selection are provided. The unit can
automatically detect the video standard and switch at the appropriate point in the frame-
blanking period or, in some modes, switch immediately upon remote command.
When used with the RM38 rear connector module relay bypass is available. This rear
module will switch input 1 to output 1 and input 2 to output 2 on complete frame power
failure or if the SW222 should be removed from the frame.
The main features are as follows:
•SDI or DVB-ASI 2 x 2 switching
•Up to 4 reclocked outputs of both switched signals
•Independent or opposite paired outputs (1>A, 2>B or 1>B, 2>A)
•Switch immediately or in vertical blanking
•Error indication of missing input signal
•Flexible yet simple remote control and/or board edge control
•Status via GPIs and/or board edge LEDs
•Relay bypass available when used with the RM38 rear connector module

Crystal Vision Introduction
3
Default outputs are two pairs of reclocked DVB-ASI complaint serial digital. Additional
four serial digital outputs are available depending on which rear modules are fitted. The
extra outputs are not DVB-ASI complaint.
It is very compact with 6 modules fitting in a 1U frame and 12 modules in a 2U frame and
24 in a 4U frame. The unit plugs into the front of the rack frame, and the universal
connection system allows a mixture of Crystal Vision modules to be used in the 1U/2U
and 4U frames.
Typical applications:
•Emergency SDI or DVB-ASI transmission bypass switcher – with preview
output
•automated n x 2 redundancy changeover switch
•Automatic fail safe switch
•Simple 2x2 manual changeover selector
Both local and remote control and tally indication is provided, making the unit ideal for
use from the critical-paths of complex automated multi-channel systems to the smallest
edit suite.
Note. for relay bypass operation a minor modification to the SW222 board may be
necessary depending on PCB issue. See Chapter 3 Installation.

The hinged front panel of the case reveals user control of the card, and also LED
indication of input status and switch routing. The 8-way piano switch allows the operating
modes, switching options and status options to be selected.

Control modes
To provide maximum flexibility a number of different controls options are available.
Piano switches 1-3 chose the control option as follows: -
Function Mode 123
Both channels selected by a single local
piano switch
O UpUpUp
Each channel selected by separate local
piano switches
I UpUpDown
Both channels toggled by repeated action of
a single remote momentary switch
O Up Down Up

separate remote momentary switches
I Up Down Down

remote momentary switches
O Down Up Up

MODE Description
IA/B output channels controlled independently
OA/B output channels always on opposite selection
The control modes are discussed in more detail in the next section ‘Using control modes’.

Auto switching on missing input
If piano switch 6 (AUTO) is up, outputs A and B will automatically switch away from a
missing input. The status outputs (‘a’ to ‘d’, depending on control mode) will indicate the
actual status of the routing. If the missing input returns, the SW222 will revert to the
selected routing.
If piano switch 6 (AUTO) is down, outputs A and B will maintain their selected routing
irrespective of input conditions.
Frame-synchronised or immediate switching
After receiving a control signal, the SW222 will, by default, change routing at the
appropriate point in the next frame-blanking period. In some modes it is possible to
disable this feature so that the routing changes within a few microseconds of the control
signal. This simplifies use with sources of timed control signals such as mixers.
If piano switch 7 (IMMEDIATE) is down, routing will change within a few microseconds
of the control signal. This facility is only available when the routing is controlled by
remote toggle switches (not on momentary control). If piano switch 7 is up, routing will
change during the next frame-blanking period.
Status switching
In some modes the GPI lines are bi-directional – they are used both as control inputs and
status outputs. If piano switch 8 (STATUS) is down, the status outputs will be disabled in
these modes. This simplifies use where multiple SW222s are controlled by one set of
remote controller. In the corresponding control mode, if piano switch 8 is up, the GPI
lines will be bi-directional.

and frame ground is pin 6 in each case and +5V @500mA is pin 15 on Remote 2 and
Remote 6.
Note. The +5V output is protected by self-resetting thermal fuses, which limit the total
output current available from Remotes 1-4 to approximately 1A. Remotes 5-8 are similarly
protected.
