*1 The maximum transmission distance shown in the above table indicates the distance when three repeaters are used.
To calculate the maximum transmission distance when repeaters are used and the transmission distance is extended, use the following
formula.
Maximum transmission distance [m/network] = (Number of repeaters + 1)  Transmission distance[m/segment]
