ELTEC BAB-740 11887 REV F PMCE-740 REV B
Product Name: ELTEC BAB-740 basic automation board with PMCE-740 PMC Ethernet mezzanine
Product Overview: BAB-740 is a VMEbus embedded automation board built around a PowerPC 740 processor. The supplied 11887 Rev F board pairs with PMCE-740 Rev B, a PCI mezzanine card that adds Ethernet and expanded I/O for industrial control, data acquisition and real-time computing.
Detailed content
Technical Specifications: The main board uses a PowerPC 740 CPU with onboard cache, flash memory, SRAM, RTC and VMEbus interface. It provides serial COM ports, parallel port, keyboard and mouse interfaces, SCSI or IDE support according to the populated options, and VME64 signaling through P1/P2 connectors. PMCE-740 adds 10/100 Mbit/s Ethernet, PCI local-bus bridging and additional serial or PMC interfaces defined by the card revision.
Functional Features: The platform supports VMEbus master/slave communication, PCI expansion through PMC cards, boot from flash or disk, remote diagnostics and long-life industrial software environments. Revision F and Rev B markings define BIOS, jumper, connector and firmware compatibility.
Performance Parameters: Operation covers typical industrial temperature ranges stated in the revision manual. The board reports activity through CPU, Ethernet, serial and VME status LEDs. MTBF, ESD tolerance and humidity limits are defined in the ELTEC BAB-740 and PMCE-740 manuals for the specific revision.
Material Composition: The board uses FR4 multilayer PCB, ceramic or plastic processor package, SDRAM/flash devices, aluminum heatsink if fitted, gold-plated VME and PCI connectors, and steel or plastic hardware.
Structural Characteristics: BAB-740 uses a standard VME single-board format with front I/O connectors and internal mezzanine site. PMCE-740 mounts on the PCI/PMC connector stack and provides rear or front Ethernet and serial access according to the cage layout.
Working Principle: The PowerPC executes the real-time operating system or firmware. VMEbus transfers data with other crate modules, PCI/PMC expands local peripherals, and PMCE-740 handles Ethernet messaging, serial telemetry and application I/O.
Installation Requirements: Insert BAB-740 into a compliant VMEbus crate on the specified slot. Install SODIMM memory and PMCE-740 mezzanine before applying power. Connect Ethernet, serial and VME terminators according to the system plan. Use ESD protection when handling boards.
Usage Precautions: Use only the firmware and jumper settings listed for 11887 Rev F and PMCE-740 Rev B. Verify VME termination, power sequencing and cooling before extended operation. Do not modify oscillator, voltage jumper or mezzanine address settings while power is applied.
