Building the Digital Nervous System for DNA Sequencing Systems

Overview

DNA sequencing systems require extremely stable and reliable communication to support long test runs, high-volume image data processing, and precise control of pumps, valves, sensors, temperature, pressure, and leak detection. Since these workflows involve valuable reagents and sensitive genomic data, even minor signal instability can cause data errors, library loss, or costly system failures.

Moxa helps equipment builders create a resilient “digital nervous system” for DNA sequencing systems. By combining high-bandwidth Ethernet, secure switching, high-density serial connectivity, and modular I/O, Moxa supports smooth data flow, easier device integration, and flexible system design for different sequencer models.

System Requirements

• High-bandwidth communication to handle large image data streams and support accurate base calling
• Secure data transmission to help protect sensitive genomic information
• Stable connectivity for long test runs where even small interruptions can cause costly failures
• High-density serial integration for pumps, valves, and other peripheral devices
• Modular I/O configuration to support different sequencer designs and faster system adaptation
• Compact and easy-to-install hardware to reduce cabinet space and wiring errors

Solution

Moxa provides an integrated connectivity framework that helps DNA sequencing systems maintain stable communication, secure data flow, and flexible device integration. The EDS-G4012 Series offers reliable and secure Layer 2 switching with IEC 62443-4-2 certification and high EMC performance, supporting uninterrupted image data transmission in demanding sequencing environments.

For serial device integration, the NPort 5650-16 consolidates multiple syringe pumps, valves, and other serial peripherals into a single Ethernet network. This allows centralized data access, reduces wiring complexity, and improves cable management inside the system.

To support flexible machine design and faster production, the ioThinx 4510 Series provides compact modular I/O with tool-free push-in wiring and slide-in modules. This helps reduce cabinet footprint, minimize manual wiring errors, and simplify adaptation across different DNA sequencer models.
