  • Page 32: Cpu Board

    RCP-MB Functional Section 4 4.1 Introduction The RCP–MB panel consists of two printed circuit boards. The CPU board contains a microprocessor that controls the panel's operation and communicates with the control system. The Switchcard contains pushbuttons and indicators used by the operator to control the routing switcher.

  • Page 33: Clock

    RCP-MB Functional Section 4 CPU Board Continued: Microprocessor Continued: During the first half of the bus cycle, port C presents the lower address byte (A0-A7). This information is latched into U2 on the falling edge of address strobe AS (U1 pin 4 to U2 pin 11) and remains stable until the beginning of the next bus cycle when AS is driven high by the processor.

  • Page 34: Memory

    RCP-MB Functional Section 4 CPU Board Continued: the RESET pin must be held low while VDD is below legal limits to protect internal EEPROM register contents. A Maxim MAX690 chip (U5) performs the reset function for the 68HC11. The MAX690 monitors the supply voltage and asserts RESET (U5 pin 7) whenever VCC falls below 4.5 Vdc.

  • Page 35: Rs-485 Communications

    RCP-MB Functional Section 4 CPU Board Continued: RS-485 Communications Communication between the panel and the system controller is accomplished by the 68HC11 internal Serial Communication Interface (SCI). The SCI is an asynchronous receiver/transmitter, sometimes referred to as a UART. The RS-485 standard is used for the electrical interface between panels and the system controller.
