2.3 Theory of Operation
The module contains all the circuitry for the CPU function: main processor, FLASH memory, SRAM, RTC,
a bidirectional buffer bank for the data, address lines and control lines coming from the processor, the
back-up capacitor, RESET circuit, isolation circuit for control signals coming from the power supply,
isolation circuit for SP8, C13S connector, Ethernet circuit, DATAKEY circuit, USB circuit, driver field circuit
(RS-485 transceivers), LINESYNC circuit, A2 and A3 connector sensor , and A5 connector.
The module is comprised of three main parts: A Host Board, an Engine Board and a Faceplate.
The faceplate is a 2X wide aluminum front plate with the necessary cutouts for the front connections; it
also has thumbscrews to be attached to the chassis.
The Host board and Engine board are shown in Error! Reference source not found.. These two major
assemblies are explained below in separated sections.
