Abstract

PURPOSE:To improve the transmission efficiency by modulating the data signal sent to a bus line and specifying an occupied frequency band for data communication. CONSTITUTION:The data signal sent from a work station 1a is modulated by a MODEM 3a to have a specific frequency as the carrier and is sent onto a bus line 2a. A work station 1a on the reception side receives the data signal in a preliminarily determined frequency band through the MODEM 3a. In this case, the collision between data does not occur even in case of mixture of data on the bus line 2a because data signals on the bus line 2a are sent onto the bus line with individual frequencies as carriers.
