The epc100 device can be operated in two different modes:
a) Photo Current Receivers
It detects current pulses of the photo diode generated by light pulses and transmits the information using the 2-wire bus to a central con -
troller, i.e. a micro controller. The devices operating as this photo current receivers are designated in the schematic diagram above as R

b) 2-Wire Bus Interface of the Central Controller
It manages the 2-wire bus traffic between the micro controller and the individual photo current receivers. The device operating as the inter-
face unit is designated as I

From the point of view of the micro controller, the whole system looks like a single device with several addressable photo diodes. The micro
controller activates one photo diode and fetches the results after a predefined time. Each sensor device has two different operation modes: A

light pulse has been received in respect to the receive window.
The receiver channel detects current pulses which are generated by light pulses in the photo diodes. The detection circuitry has two trigger
levels, hereinafter called thresholds, which form a digital signal from the analog current change. The lower threshold is called OUTN (normal)
whereas the upper level is called OUTH (high). Both trigger thresholds can be configured individually per chip. Please refer to Figure 2 and to
the Reference Manual epc10x which contains the configuration information.
