GENERIC OPERATION OF COMMERCIAL SWITCHERS with AUTONOMOUS MCU

INPUTS
SEEING

GENERIC SWITCHER:
Any switcher, can be made intellegent when married to one of my MCU modules.
These broadcast analog switchers (can be grass valley or videoteck) can easily be used for automated switching by having the switcher join the net. The Net has much more knowledge external events.

For example security
This switcher will automatically select video and audio from the disturbed area.
No computer is required... The Net has knowledge of motion detectors and door openings.

Besides security, other aplications for these switchers include programming. In combonation with my sync detectors, these switchers can switch active video (and audio) automatically according to pre-set rules. For example, if programming normally comes from the microwave, and there is a failure of this source, then alternate sources could be routed automatically. These cheap analog switchers can be made intellegent and autonomous by my system.

LOCAL SWITCHES may be disconnected completely.
You do not need the front button pannel.

Typical connection to my control module board. Control board connector to switcher is at end of J2.
This is for serial type control.

This is for BCD type control.
