Technical Manual (English, Organized)

1. General Description

• 012A: Industrial standard temp (0°C~+55°C), revised Ethernet/IP logic, improved reset/abort circuitry, no SCSI.

• 012: Earlier revision, same core I/O (Ethernet + IP slots, no SCSI).

2. Core Specifications

• Processor: Motorola MC68LC040 @ 25 MHz (no FPU, with MMU, 8 KB internal cache)

• DRAM: 4 MB parity‑checked DRAM (factory fixed, non‑expandable on 012A)

• Battery‑Backed SRAM: 512 KB

• Flash Memory: 1 MB (for 162BUG firmware)

• NVRAM/RTC: 8 KB NVRAM + Real‑Time Clock (TOD), battery‑backed

• VMEbus: A32/D32, master/slave, system controller capable

3. Onboard Interfaces

• Ethernet: 10 Mbps Ethernet (AUI / 10BASE‑T) with DMA (Intel 82596CA controller)

• IndustryPack (IP): 4 × single‑width IP slots (or 2 × double‑width) for I/O expansion

• Serial Ports:

  • 1 × Console: EIA‑232‑D (DCE)

  • 1 × Configurable: EIA‑232‑D / EIA‑530 (DCE/DTE)

• Timers: Six tick timers + watchdog timer

• Front Panel:

  • 8 LEDs: FAIL, STAT, RUN, SCON, LAN, FUSE, SCSI (unused), VME

  • 2 pushbuttons: RESET, ABORT

• Not included: SCSI interface (012A = Ethernet + IP, no SCSI)

4. Mechanical & Environmental

• Form Factor: 6U VMEbus, single slot

• Operating Temperature: 0°C ~ +55°C (industrial grade)

• Storage Temperature: ‑40°C ~ +85°C

• Humidity: 5%–95% non‑condensing

5. Firmware & Software Support

• Boot Monitor: 162BUG (Motorola proprietary)

• Supported OS: VxWorks, LynxOS, OS‑9, pSOS+, VRTX, OpenBSD/mvme68k, NetBSD/mvme68k

• Functions: Power‑on self‑test (POST), memory/VME mapping, serial console, Ethernet/IP configuration, watchdog control

6. MVME162 Series Comparison (Key Models)

• MVME162‑010A: IP slots + dual serial, no SCSI/Ethernet

• MVME162‑011A: SCSI‑2 + 512KB SRAM, no Ethernet/IP

• MVME162‑012: Ethernet + IP slots, no SCSI (early rev)

• MVME162‑012A: Ethernet + IP slots, no SCSI (industrial rev, improved reliability)

• MVME162‑013: SCSI + Ethernet, no IP slots

7. Typical Applications

• VMEbus industrial automation & DCS

• Embedded systems requiring Ethernet + modular I/O (IP)

• Real‑time test & measurement (ATE)

• Migration/replacement for legacy MVME162 fleets

8. Maintenance Notes

• Replace onboard backup battery every 3–5 years to preserve SRAM/RTC data

• Configure VMEbus master/slave via onboard jumpers

• Verify IP module seating and Ethernet cable termination before power‑on
