Crystal Vision Introduction

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 frameblanking 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

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.

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 1 2 3

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

MODE

Description

I A/B output channels controlled independently

O A/B output channels always on opposite selection

The control modes are discussed in more detail in the next section ‘Using control modes’.

Crystal Vision Operation

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.

Table shows pin number (remote number)

Note:

Remote 1 and Remote 3 are 26-way high-density D-Type female sockets. Frame ground is pin 2 and +5V @500mA is pin 1 in each case.

Remote 2 and Remote 4 are 26-way high-density D-Type male plugs and frame ground is pin 6 in each case and +5V @500mA is pin 15 on Remote 2.

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.

Indigo 1 and Indigo DT Desktop box GPI connections

GPI lines ‘a’ to ‘f’ of each card connect to one of two rear remote connectors as follows:

Slot no. ‘a’ pin ‘b’ pin ‘c’ pin ‘d’ pin ‘e’ pin ‘f’ pin

Table shows Pin number (Remote number)

Note:

Remote 1: 26 way high-density D-type socket. Frame ground is pin 2 and +5V @500mA is pin 1. Remote 2: 26 way high-density D-type plug. Frame ground is pin 6 and +5V @500mA is pin 15.

3.3 DVB/SDI configuration

If inputs 1 and 2 are DVB-ASI signals, for the input detect LEDs and GPI status lines to function correctly, jumper links PL3 (input 1) and PL4 (input 2) must be moved to the DVB-ASI position.

With PL3 & PL4 in the DVB-ASI position and piano switch 6 up, the SW222 will automatically switch away from a missing DVB-ASI input.

With PL3 & PL4 in the DVB-ASI position, the SW222 will function fully with SMPTE-259M inputs although, at long cable lengths, performance of the input detection and auto-switching functions may be diminished.

Crystal Vision Problem solving

Basic fault finding guide

The Power OK LED is not illuminated

Check that the frame PSU is functioning – refer to the appropriate frame manual for detailed information

There is no video output

Check that valid SDI or DVB-ASI input(s) are present and that any cabling is intact

The video output is not synchronous with other sources when switched

Check that both inputs are already synchronous and correctly timed as required by the overall system

Switching does not take place in the vertical interval

Check that DIP switch 7 is in the UP position or that the remote trigger is correctly timed

Status indication does not work as expected

Check that board jumpers PL3 and PL4 are configured correctly for either SDI or DVB-ASI inputs

Switch does not change state when an input is missing

Check that DIL switch 6 is in the UP position

Outputs transpose input selection when switch operated

Check that the appropriate mode is selected with DIL switches 1, 2 and 3

Local input select controls do not work

Check that the appropriate mode is selected with DIL switches 1, 2 and 3

Remote operation has failed

Check that the appropriate mode is selected with DIL switches 1, 2 and 3

Check the remote cable connections and remote control facilities

External status LED or bulb illumination is incorrect

Check that the appropriate series resistors have been used and that any bulbs are rated correctly

Re-setting the card

If required, the card may be reset by simply removing the rack power and re-applying power after a few seconds or by removing the card from the rack re-inserting the card

It is safe to reinsert the card whilst the rack is powered

Relay bypass not functioning
