Abstract

PURPOSE:To achieve an economical remote power supply application system, by providing a power supply application code pulse generator and electro-photo converter at the central port, and providing a code pulse discriminator and photooptic converter and further an auxiliary power supply at a remote port. CONSTITUTION:When the operator at a central port P2 operates a power supply switch at a remote port P3, a power supply application code pulse generator 3 is started, a pulse signal is transmitted via an electrooptic converter 2 and an optical transmission line 5 to a power supply application code pulse discriminator 8 through an photoelectric converter 6 at the remote port P3. Power is applied to the converter 6 and the discriminator 8 with an auxiliary power supply 9. A power supply application signal is produced to a main power supply 10 when the port number of itself and pulse signal number coincide in the discriminator 8, and the main power supply 10 of the port P3 turns on.
