Product Features
Technical Overview
This industrial-grade serial hub supports individual port configuration, allowing each of the four DB9 male ports to operate as RS232, RS422, or RS485 (2-wire/4-wire) interfaces. Data transfer rates reach up to 921.6 Kbps, suitable for high-speed communication with devices like barcode scanners, printers, PLCs, and sensors.
The adapter features 15kV ESD surge protection (Level 4) and an IP30 rating, providing enhanced electrical and physical protection in industrial settings. All ports are equipped with locking connectors to prevent accidental disconnection, ensuring continuous operation in vibration-prone environments.
Relevant factors for this section include Host Interface, Platform Supported, Number of Serial Ports (External). When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
Key Product Advantages
This serial hub stands out with its versatile power options and broad compatibility, designed to integrate seamlessly into diverse industrial and commercial setups.
Flexible Power Supply
The hub can be powered via the included 12V screw-locking power adapter or directly from the 5V USB host connection. Each serial port's pin 9 can be individually set to 5V, 12V (requires power adapter), or 0V, providing tailored power delivery for connected devices.
Wide Platform Support
Compatible with current and legacy versions of Windows, Linux, and macOS, as well as various embedded platforms. This ensures connectivity across a wide range of systems, from modern workstations to older industrial terminals.
Rugged Industrial Design
The metal construction, combined with surge protection and locking connectors, offers durability and reliability in harsh conditions, reducing downtime and maintenance needs.
Deployment / Use Cases
This adapter is ideal for environments where legacy serial devices need to connect to modern USB-based systems. Its robust design and flexible mounting make it suitable for factory floors, retail POS systems, laboratory equipment, and telecommunications infrastructure.
Common applications include connecting barcode scanners, label printers, CNC machines, scientific instruments, and network equipment that rely on serial communication. The DIN rail mounting capability is particularly valuable for organized installations in control cabinets and industrial racks, where space efficiency and secure mounting are critical.

Physical Profile
The hub features a compact external form factor measuring 4.60" wide by 1" high (116.84 mm x 25.40 mm), with a weight of approximately 13.50 oz (382.72 g). Its low-profile design and built-in mounting ears allow for discreet installation in space-constrained areas. The industrial metal finish not only enhances durability but also provides effective heat dissipation during continuous operation.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1" (25.40 mm), 4.60" (116.84 mm), 13.50 oz (382.72 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
