Abstract
A communication system includes a host device and a peripheral device. The host device includes a data terminal and a power terminal. A data conductor extends between the host device and the peripheral device. The data conductor is configured to channel data between the data terminal and the peripheral device. A power conductor extends between the host device and the peripheral device. The power conductor is configured to channel power between the power terminal and the peripheral device. A zener diode couples the data conductor to the power conductor. The zener diode is configured to control a voltage channeled between the host device and the peripheral device while data is channeled through the data conductor at a desired speed that is greater than a predetermined threshold.
