摘要

Transmission between two cards is disabled if power is not supplied to one of the cards. The system includes a first card generating a first power signal based on power applied to the first card. A second card, in communication with the first card, generates a second power signal based on power applied to the second card. A transmitter on the first card transmits to a receiver on the second card. The transmitter is disabled from transmitting based on the second power signal and the receiver is disabled from receiving based on the first power signal.
