Claim Text:
1. A ruggedized network interface appliance for ensuring secure data transfer comprising: send-only network interface circuitry comprising a processor, a program memory, a first host interface, and a first serial interface; receive-only network interface circuitry comprising a processor, a program memory, a second host interface, and a second serial interface; a single data link connecting the first serial interface of the send-only network interface circuitry to the second serial interface of the receive-only network interface circuitry; wherein the send-only network interface circuitry is configured not to receive any data from said data link, and said receive-only network interface circuitry is configured not to send any data to said data link; and wherein the send-only network circuitry and the receive-only network circuitry reside on a single circuit board, wherein the single circuit board has three separate contiguous areas, a first area containing the send-only network circuitry, a second area containing the receive-only network circuitry and a third area disposed directly between the first area and the second area containing no electrical connections between the first area and the second area, and wherein the single data link comprises only a single optical isolator device which spans the third area but has no connection thereto.
