<p>One embodiment describes a fault tolerant transmission system 10 that includes a programmable logic device 15. The programmable logic device 15 includes a first serial port communicatively coupled to a first serial link 40, in which the first serial port receives a first transmission signal from the first serial link, and a second serial port communicatively coupled to a second serial link 42, in which the second serial port receives a second transmission signal from the second serial link. The first serial link and the second serial link are disposed in parallel with each other and communicate over a first single conduit 38, and the first communication signal and the second communication signal are representative of identical information. The programmable logic device 15 further includes circuitry that detects a fault in the first serial link, the second serial link, or both by comparing the first communication signal and the second, and if a fault is detected, determines whether the transmission system 10 can continue operation despite the fault.</p> |
