PURPOSE:To easily find out a fault caused by difference of each transmission speed by informing of it when transmission speeds differ from each other. CONSTITUTION:Plural data transmitters are interconnected via a transmission line. Each data transmitter 1 is provided with a transmission speed discrimination section 13 which receives a reference pattern signal sent through the transmission line in a prescribed timing and discriminates the transmission speed of the reference pattern signal. A transmission speed fault notice section 16 raises a notice when a transmission speed set by a transmission speed setting section 14 and a transmission speed set by a transmission speed setting section 13 are dissident. |
