McCain ATC eX NEMA - Engine Board Sub-Assembly (M69588 A)

McCain ATC eX NEMA Controller – User Manual 13
Version 1.0
• A fourteen positions header (P5) for plugging the keypad.
• A buzzer (BZZ1) as an audible interface to the user.
2.6.4 Engine Board Sub-Assembly (M69588A).
This module meets the ATC 5.2b Standard (Form, fit and function) and it is the brains of the ATC eX
NEMA Controller; all computational functions are concentrated here; it contains the CPU, memory
devices, and serial interface devices providing synchronous and asynchronous serial communications
channels, Ethernet interfaces, USB interface, RTC, and a SPI bus. It uses Linux operating system.
The board hardware features are:
• CPU, it is a Freescale microprocessor is a MPC8360 at 400MHz
• FLASH, 16MB are provided for storing the operating system and the applications programs.
• SRAM, 2MB are provided for non-volatile parameter storage.
• DDR2, 128MB are provided for application and OS program execution.
• RTC.
• Seven serial communication channels (SP1, SP2, SP3, SP4, SP5, SP6 and SP8).
SP1 and SP2 designated for communication on the modem board located on 2070 slot.
SP3 for a synchronous communication channel, it is the SDLC port on controller’s front panel.
SP4 for a terminal and general purpose port (PORT 2) on controller’s front panel.
SP5 for a general purpose port (SP-5) on controller’s front panel.
SP6 for handling the LCD’s and keyboard information.
SP8 for a general purpose port (SP-8) on controller’s front panel.
• Two Ethernet interfaces (Port 1 and Port 2). These interfaces go to the Ethernet switches on the
host board.
• One USB interface that goes to the USB switch on host board.
• One SPI bus that handles the communication to an optional connector box, when configuration
for a TS2 Type 2 controller is needed.
• Two 50 positions plug connectors to be attached to a host board.
