  • SDI 2 x 2 Switch
  • 100mm x 26mm module allows 12 SW222 in 2U
  • Two reclocked outputs
  • Switch immediately or in vertical blanking
  • Automatic detection of faulty inputs
  • Controllable by piano switches or GPIs
  • 4 GPI inputs with independent tally
  • Very simple to connect up



MECHANICAL
Standard Crystal Vision module 266mm x 100mm
Weight: 150g
Power consumption: 5 Watts

INPUTS
All 270Mbit to EBU 3267-E & SMPTE 259M
2 SDI inputs (1 and 2)
Cable equalisation >200m Belden 8281 or equivalent
Auto 625/525 line selection

OUTPUTS
Reclocked 270MMbit to EBU 3267-E & SMPTE 259M
A x 2 and B x 2 with rear module RM01; A x 3 and B x 4 with RM02; A x 4 and B x 4 with RM18

SWITCHING
Electronic switching between SAV and EAV at line 6 or immediate switching if input missing (or immediate switching selected on piano switch)
Switching can be controlled from the board edge or by GPI
GPI control can be configured in six different ways, allowing for direct connection to lamps and switches in a number of different configurations, or to an automation system

AUTO SWITCHING ON MISSING OUTPUT
The outputs of the switch can be configured to automatically switch away from a missing input. The SW222 will return to the previous selection when the input returns. An input is considered missing if successive SAV and EAV sequences are not detected for 3 consecutive line periods

GPI INPUT LEVELS
Active: connect to ground
Inactive: high impedance or 3 to 48 volts
Input current <500uA

GPI OUTPUT LEVELS
Lamp driver outputs, active low, with pull-ups
Links can be replaced with resistors to drive LEDs if requested when ordered
Max current -300mA
Lamp drive is multiplexed with GPI inputs in some modes to allow for four control inputs and four lamps. This can be switched off

LED INDICATION OF:
Power supplies
625/525 input detected
Inputs present
Selected input for each output

PIANO SWITCH CONTROL OF:
Switch inputs
Auto switch away from missing SDI input
Immediate switch without waiting for correct line in vertical interval
GPI control mode (see below)
Multiplexed GPI control/lamp drive status (only in modes uing 4 GPI inputs)

GPI CONTROL MODES
Each output can be selected by: the position of a remote switch, the repeated action of a single remote momentary switch, the most recent of two remote momentary switches or a local piano switch (GPI off)
Outputs A and B can be controlled separately, or output B can be forced to be the opposite of output A
Tally outputs are provided to drive the lamps in all switches
