Product Short Description

Functional Features

  • Standardized I/O Connectivity: Converts proprietary SBC I/O to off-the-shelf connectors (RJ45, DB – 9/25), reducing custom cable costs and lead times.
  • Flexible Serial Protocol Support: Two configurable serial ports work with EIA – 232 to X.21 protocols, adapting to industrial modems, WAN links, and legacy field devices.
  • SIM – Enabled Reconfiguration: 60 – pin SIM connectors let users swap serial interface types without replacing the entire module, supporting mixed – protocol deployments.
  • Integrated EMI/ESD Protection: Shields against electrical noise and static discharge, ensuring signal integrity in factory floors and control rooms.
  • Plug – and – Play VME Integration: Fits any standard 6U VME slot, pairs with MVME SBCs for immediate I/O access without backplane modifications.
  • Ethernet Auto – Sensing: 10/100Base – TX port auto – negotiates speed, simplifying network integration with SCADA systems and enterprise LANs.
  • Parallel Port Compliance: IEEE 1284 – I parallel port connects to industrial printers, barcode scanners, and data loggers for local output tasks.
  • Industrial Cooling Compatibility: Operates at 0–55°C with 5 CFM airflow, matching MVME SBC thermal profiles in rack – mounted VME systems.
