System compatibility

MVME188A belongs to Motorola MVME188 VME series single board computer.It can work with standard VME backplane and matched VME I/O modules,widely used in old industrial control,test measurement and semiconductor equipment.It is spare part for legacy equipment overhaul.

Function

MVME188A is a 6U VME single board computer based on MC88100 RISC multi-processor shturl.cc/SzPVi supports embedded real-time operating system,performs complex control logic operation and field data acquisition.It communicates with peripheral modules via VME bus and serial ports.It has onboard watchdog timer and real-time clock for reliable long-running embedded control.This variant adopts 25MHz MC88100 multi-processor cluster with HyperModule mezzanine design.

Installation

Insert MVME188A into standard 6U VME chassis slot,lock the front panel.Fix the board,connect serial cable and VME backplane.Take ESD protection before power-on.

Interface

‑VME backplane connector

‑Dual RS232 serial port

‑Watchdog timer

‑RTC battery backup circuit

‑+5V power terminal

Feature

MVME188A classic industrial SBC.Typical faults:gold finger oxidation,DRAM chip failure,serial transceiver damage,battery leakage.Clean gold finger and test memory before replacement.

Diagnostic

Fault phenomenon:no power on,boot failure,VME bus communication error,serial port no data output.Check VME backplane power supply,clean gold finger,test DRAM and communication circuit.

Product Brief

MVME188A is Motorola 6U VME single board computer with MC88100 25MHz multi-processor cluster,up to 128MB DRAM,with dual RS232 serial ports.It is standard temperature version,mainly used for maintenance and replacement of old VME industrial control equipment.ESD protection must be followed during handling.
