A communication system comprising a first communication apparatus and a second communication apparatus. The first communication apparatus includes a communicating section that communicates with the second communication apparatus via a first data signal line; an alive signal receiving section that receives, via a first alive signal line, an alive signal indicating whether the second communication apparatus is in an alive state in which it is capable of communicating with the first communication apparatus; and a reset signal transmitting section that, when the second communication apparatus is not in the alive state, transmits a reset signal to the second communication apparatus. The second communication apparatus includes a communicating section that communicates with the first communication apparatus via the first data signal line; an alive signal transmitting section that transmits the alive signal via the first alive signal line; and a reset signal receiving section that, upon receiving a reset signal, resets the communicating section of the second communication apparatus.
