<P>PROBLEM TO BE SOLVED: To complete transmission/reception within one frame even the distance between transmission devices is widened and transmission distance is long. <P>SOLUTION: A transmission device that is connected to a transmission/reception destination transmission device and performs two-way communication with the transmission/reception destination transmission device converts transmission data into a transmittable format to send the converted transmission data to the transmission/reception destination transmission device; receives data sent by the transmission/reception destination transmission device as a response to reception of the transmission data, as an input signal; monitors the voltage value of the received input signal; treats a prescribed length of time as an unit called a frame; and, when it is determined, on the basis of the voltage value, that the time from the start of the transmission to the end of the reception does not fit in one frame, adjusts the method of the conversion, without changing the length of the frame, such that the time from the start of the transmission to the end of the reception fits in one frame. <P>COPYRIGHT: (C)2012,JPO&INPIT |
