1. In a remotely readable meter register encoder of the type including a motor and a unitized optics illuminator having a light source for providing light signals through apertured scanning and encoder discs to first and second photo-sensors to effect the generation of synchronized first and second signals representative of timing and data information respectively for use by an external device, the combination comprising:

  • (a) connecting means connecting the encoder to said external device for providing timing and data signals thereto and for receiving excitation current from said external device; and

    (b) a circuit board mounted on the meter register encoder, said circuit board including,(1) timing and data signal generation circuits connected to said first and second photo-sensors respectively and to said connecting means, said timing and signal generation circuits responsive to the first and second signals respectively from said first and second photo-sensors to provide synchronized timing and data signals to said external device via said connecting means, and(2) means connected to said connecting means, including means for providing excitation current to said timing and data signal generation circuits and to said light source and motor from said external device to effect the reading of the timing and data signals from said timing and data signal generation circuits.
