Curtiss-Wright / Systran VMESC5 IP Module Carrier

The Curtiss-Wright/Systran VMESC5 is a VMEbus IP Module Carrier that integrates up to five Industry Pack modules into a single VME6U slot, delivering high-density I/O expansion for industrial and embedded systems. The carrier supports up to 250 I/O points and achieves approximately 2.7 million transfers per second for 8- or 16-bit reads and writes, operating as a VME6U slave with A16/D16 transfer capability within a 2 KB address space.

## Technical Specifications

• IP Module Capacity: 5 modules per VME6U slot
• Maximum I/O Points: 250 on a single carrier
• Data Throughput: ~2.7 million transfers per second (8- or 16-bit)
• VMEbus Interface: A16/D16 transfers within 2 KB block
• Interrupt Request Delay: 14 ns typical (IP module to VMEbus)
• IACK Daisy-Chain Delay: 64 ns typical
• Interrupt Levels: All 10 IP module interrupt requests (2 per module) assignable to any of 7 VME interrupt levels
• Hold States: None for I/O, ID, and INT transfers; IP memory transfers not supported
• Strobe Connections: 5 total, one per slot
• General-Purpose Registers: 5 user-defined registers
• Board Base Address: Jumper selectable

## Key Features

• Individual software reset control for each IP module
• Optional P2 connector routing for up to 50 I/O lines
• Large ground plane beneath IP modules for analog signal integrity
• Field-replaceable fuses with filtered power distribution on all IP sources
• Status LEDs for carrier and IP module access diagnostics
• ID space write support
• Carrier register map including IP Reset, Error Status, and interrupt registers

## Typical Applications

High-density I/O expansion in VME-based industrial control, data acquisition, and embedded test systems requiring flexible module configuration and field diagnostics.

## Compatibility & Integration

Designed for VME6U backplanes. Accepts five standard I/O ribbon-cable connectors for IP module integration. Operates as VME slave, receiving timing and bus control from backplane.
