OPTICAL WIRELESS SIGNAL RECEIVER

摘要

PURPOSE:To facilitate setting by a sub-address for discrete control of the load connected to an address for discriminating a signal receiver, providing a sub- address set input means in correspondence only to the one load and determining the corresponding sub-address at a specified standard in accordance with the sub-address if there is the load connected to others. CONSTITUTION:The loads 21 to 24 are connected to a signal processing circuit 1 and switches S1 S2 constituting the sub-address setting input means 6 in correspondence to the specific load 21 are connected to the input ports I0, I1 of the processing circuit 1. The sub-address is of 3-bit constitution and the MSB is fixed at a logic value '1'. The remaining two bits are set at S1, S3. The '1' is successively added from the sub-address of the load 2 to determine the sub- addresses for the other loads 22, 24 and this sub-address is stored into a memory. The sub-addresses of the other loads are eventually automatically changed and set simply by setting the sub-address of the load corresponding to the sub- address input means when the plural loads are connected according to this constitution. The labor is thus saved and the generation of a setting error is obviated.
