Bus Switches
Bus Switches are devices that enable system architecture to be reconfigured. This reconfiguration is mostly accomplished in the test environment and includes but is not limited to simulation of missile firing and switching in or out a new section of bus interface.
Excalibur Systems is the only manufacturer of devices (ESI-R24/27/28) that contain their own TTL driver circuitry that allows them to be directly driven from a computer.
