We can also offer a wide range of switching subsystems based on standard units such as the DDA219, DDA89, the DDA286, or on various other standard modules. Signal types switched comprise anything that will go through a mechanical relay or switch - latching types are used wherever available for best reliability and minimum power consumption. Where appropriate solid state switching can be used - for example PIN diode switches, audio matrices, RS-422 data. Alternatively commercially available routers are used in conjunction with our controller to provide special signal handling requirements, or where size or other considerations dictate.
Examples of switching systems built to date include:
- Modem Redundancy Switches
- Baseband and IF switching
- Modem settings updated on changeover
- Facilities similar to DDA89-02
- Video encoder/decoder redundancy switches
- Balanced audio and IF switching
- Encoder/decoder settings updated on changeover
- Video Redundancy Controllers
- All switching via routers
- Standby only controlled
These are just a few of the configurations which are possible; to discuss your particular application please contact the factory.
