The Prosoft MVI69-GSC is a high-performance, single-slot network interface module engineered specifically for the Rockwell Automation CompactLogix platform. This module facilitates seamless integration between the 1769 backplane and generic ASCII serial devices, including barcode scanners, weigh scales, and industrial printers. By offloading serial data processing from the main controller, the MVI69-GSC reduces CPU overhead and optimizes overall system response times, making it an ideal solution for logistics, automotive manufacturing, and food processing applications.
Features
Dual independent serial ports supporting RS-232, RS-422, or RS-485 configurations.
Direct 1769 backplane integration for efficient data exchange.
Supports baud rates ranging from 110 bps to 115.2 kbps.
Character-based data management via an internal database, allowing the CompactLogix controller to handle serial strings as standard I/O data.
Scalable design supporting simultaneous communication with multiple field devices.
Applications
This module is widely utilized in industrial automation environments requiring the integration of legacy serial instrumentation into modern control architectures. Common applications include data acquisition from weigh scales, tracking via barcode scanners, and command-based communication with serial-enabled printers or displays.

Installation Guidelines
Ensure the CompactLogix rack is powered down before inserting or removing the module to prevent electrical damage.
Slide the module into the designated 1769 slot and secure it using the integrated locking mechanism.
Use shielded serial cables to minimize EMI interference, especially in high-noise industrial environments.
Ensure proper grounding of the serial cable shields at one end to prevent ground loops.
Configure port settings (baud rate, parity, data bits) via the software configuration tool to match the connected field device requirements.
FAQ
Does the MVI69-GSC require external power?
No, the module draws all necessary logic power directly from the 1769 backplane.
Can I use different serial standards for the two ports?
Yes, the two ports are independent and can be individually configured for RS-232, RS-422, or RS-485 operation depending on the requirements of your field devices.
