Emerson / Motorola / Force Computers SYS68K/ISIO-2 VME Serial Interface

The Emerson/Motorola/Force Computers SYS68K/ISIO-2 is a single-slot VME serial interface module engineered for VMEbus-based systems requiring industrial-grade serial communication. This interface board integrates an AM85C30 Serial Communications Controller to deliver configurable serial connectivity across multiple channels, supporting RS232, RS422, and RS485 protocols for control, telemetry, and data acquisition in demanding operational environments.

## Technical Specifications

• **Form Factor:** Single-slot VME module
• **Serial Controller:** AM85C30 Serial Communications Controller (SCC)
• **Serial Interface Options:** RS232, RS422, RS485 (configurable)
• **Bus Interface:** VMEbus
• **External Connectivity:** Rear Transition Module support (SYS68K/ISIO-1FP configuration)

## Key Features

• Front panel status indicators: RUN, LOCAL, and HALT LEDs
• Run/Local (R/L) selector switch for mode control
• Multi-protocol serial architecture for flexible deployment
• Multiple serial channels per module configuration
• Rear transition module compatibility for external port accessibility

## Typical Applications

• Industrial control systems and supervisory monitoring
• Data acquisition networks requiring serial backbone connectivity
• Equipment interfacing and legacy system integration within VME architectures
• Multi-channel telemetry and instrumentation systems

## Compatibility & Integration

The ISIO-2 operates as part of the SYS68K series ecosystem and integrates directly into VMEbus backplanes. It pairs with CPU boards such as the SYS68K/CPU-40/41 and other SYS68K modules to form complete embedded control and communication platforms. Rear transition modules enable standardized connector interfaces for field wiring and external device connectivity.
