Workstations may advantageously be interconnected in a cluster arrangement wherein multiple 'slave' stations utilize the database which exists in a 'master' unit. The cluster interface has been implemented as a wired system but the latter involves significant limitations as to distance between units, electrical noise restricting data transmission rates and the protection of sensitive data from compromise. The fiber optic interface module of the present invention eliminates the foregoing limitations by translating the electrical signals of the wired system into optical signals for transmission and restoring them to electrical signals at a receiving unit.

The present disclosure describes an isolator/switching assembly for use in a message terminal system. The assembly permits a pair of electronic data processors, one on-line and the other a back-up unit, each processing confidential or so called 'red' data, to interface with each other and both units to interface with and control a common peripheral device or I/O port. At the same time, the assembly provides physical and electrical isolation between the processor and the peripheral device and insures the TEMPEST security of the entire system.

The present disclosure describes electrical circuit means for providing an automatic power restart for unattended electrical equipment, such as computer cabinets, after an AC power failure and subsequent power restoration. The restart function is performed without interfering with the normal cabinet power sequencing during attended operation or maintenance. The circuit which utilizes a latch-in type relay to 'remember' the last manually selected power control setting has general utility in new installations, as well as being adaptable to existing cabinet power systems.
