III. MVME162-10 / 200 Minimal Comparison (Plain Text)

10: LC040/25/❌ FPU/4MB/❌ Network /❌ SCSI/4IP/2 Serial Ports → Basic Model

200: LC040/25/❌ FPU/1MB/❌ Network /❌ SCSI/2IP/4 Serial Ports → Ultra-Simplified Model

IV. Functional Features

Minimum configuration of the series: 1MB memory, 2 IP slots, no network, no SCSI, lowest cost

Multiple serial ports: 4 RS-232, suitable for multi-serial port device control (such as multiple instruments / sensors)

No floating point, no extended storage: only suitable for simple integer control, no local storage scenarios

Basic power-off protection version: SRAM/NVRAM/RTC battery backup

V. Typical Applications

Ultra-low-cost VME control: simple logic, no network, no storage, multiple serial ports

MVME162-10 downgrade replacement: budget limited, no need for 4MB/4IP, use 200 to reduce cost

Industrial equipment multi-serial port acquisition: 4 serial ports for multiple sensors / instruments, no complex operations
