Abstract
A data transmission system comprising a plurality of connecting units, data lines interconnecting the connecting units in a sequence to form a data bus, and a plurality of data terminals. Each terminal is directly connected to a respective one of the connecting units to transmit data between the terminal and that connecting unit, and each connecting unit is switchable between normal and bypass states. In the normal state, each connecting unit transmits data from the immediately preceding connecting unit both to the next following connecting unit and to the terminal directly connected to the connecting unit, transmits data from the immediately preceding connecting unit to the next following connecting unit, and transmits data from the directly connected terminal to the next following connecting unit. In the bypass state, the connecting unit transmits data from the immediately preceding connecting unit to the next following connecting unit.
