StarTech.com RS232, RS422, RS485 Interface Converter 4

This Interface converter provides a Compact solution to bridge USB hosts with serial industrial buses, facilitating communication between a computer and devices using RS232, RS422 or RS485 standards. Designed for DIN-rail installation, it converts a single USB Type-B connection into four serial ports presented on a D‑Sub output, supporting industrial environments where multiple serial links are required.

• Supports RS232, RS422, RS485 for flexible bus compatibility • Four‑port output enables multiple device connections • USB Type‑B Interface for standard host connectivity • DIN‑rail mount simplifies panel and cabinet installation • Maximum data throughput of 921.6 kbps for high‑speed serial links • ESD protection reduces the risk of electrostatic damage

• Suitable for industrial automation controllers requiring multiple serial links • Ideal for factory‑floor data acquisition systems using RS485 networks • Used with PLCs that need USB‑hosted serial gateways • Can be used for fieldbus protocol converters in control cabinets • Used for remote monitoring stations that aggregate serial sensors

A single USB Type‑B connection provides the host Interface while the converter exposes four serial ports via the D‑Sub connector.

The unit is designed for attachment to a DIN rail to integrate neatly into control enclosures.

The device includes ESD safeguards to help protect interfaces from static discharge events.

The converter supports serial communication up to 921.6 kbps, suitable for demanding data transfers.
