Interface device and image forming apparatus |
摘要 |
An interface device includes a parallel-to-serial converting unit, a driver, a receiver, and a serial-to-parallel converting unit. The parallel-to-serial converting unit converts parallel signals into a single-ended signal. The driver converts the single-ended signal from the parallel-to-serial converting unit into a differential signal and transmits the differential signal to an external device via signal lines. The receiver converts a differential signal received via the signal lines from an external device into a single-ended signal. The serial-to-parallel converting unit converts the single-ended signal from the receiver into parallel signals. A direction in which the differential signal is to be transmitted is determined based on a control signal. |
