McCain ATC eX2 NEMA Controller
– User Manual
11
Version 1.0

A fourteen positions header (P5) for plugging the keypad.

A buzzer (BZZ1) as an audible interface to the user.
2.5.4 Engine Board Sub-Assembly (M52284A).
This module meets the ATC 5.2b Standard (Form, fit and function) and it is the brains of the ATC eX2
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

NOR FLASH, 16MB are provided for storing the operating system and the applications programs.

NAND FLASH, 256MB are provided for storing the operating system and the applications
programs.

SRAM, 2MB are provided for non-volatile parameter storage.

DDR2, 256MB 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 and
also available on the “C12S SP5/SP3”.
SP4 for a terminal and
general purpose port (PORT 2) on controller’s front panel.
SP5 for a general purpose port (C12S SP5/SP3
) 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 (ETH1 and ETH2). 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.
