Product Features
Technical Overview
This serial hub delivers flexible serial port management with each of its eight DB9 male ports individually configurable to RS232, RS422, or RS485 (2-wire or 4-wire) standards. Baud rates extend up to 921.6Kbps, supporting high-speed communication with devices like barcode scanners, label printers, CNC machines, and legacy industrial controllers.
Power flexibility is a key technical advantage: the hub operates from either the included 12V screw-locking universal power adapter (compatible with NA/JP, UK, EU, ANZ outlets) or 5V USB bus power. Additionally, each serial port's pin 9 can be configured to supply 5V, 12V (requires power adapter), or 0V, enabling direct power to connected peripherals without external supplies.
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 hub stands out in industrial settings by combining robust protection with configuration flexibility. The metal enclosure and comprehensive surge protection ensure reliability where electrical interference or physical stress might compromise lesser adapters.
Rugged Design for Harsh Environments
The industrial metal construction, IP30 rating, and 15kV ESD protection on all ports defend against dust, moisture, and electrical surges, making it suitable for factory floors, outdoor installations, or unstable power conditions.
- Metal housing resists impact and corrosion
- IP30 rating protects against solid objects >2.5mm
- 15kV ESD protection meets IEC 61000-4-2 Level 4
Flexible Mounting & Installation
With built-in mounting ears, included DIN rail brackets, and a 6ft (1.8m) screw-lock USB cable, the hub installs securely on desks, walls, DIN rails, or inside enclosures without requiring additional hardware.
- DIN rail mounting for control panel integration
- Wall or desk mounting via pre-drilled ears
- Screw-lock USB cable prevents accidental disconnection
Wide Compatibility Across Platforms
Driver support extends across current and legacy Windows, Linux, macOS, and embedded systems, ensuring connectivity with both modern computers and older industrial PCs or single-board computers.
- Plug-and-play on most operating systems
- Legacy OS support for older equipment
- Embedded platform compatibility for custom applications
Deployment / Use Cases
This serial hub is engineered for scenarios where multiple serial devices must interface with modern computing infrastructure. Its ruggedness and flexible configuration make it ideal for industrial automation, retail environments, and legacy system integration.
In manufacturing or process control, it connects PLCs, HMIs, sensors, and motor drives to a central monitoring PC. For retail, it consolidates receipt printers, cash drawers, barcode scanners, and customer displays at point-of-sale stations. In telecommunications or broadcasting, it manages serial-based routers, switches, or audio/video equipment racks.
Industrial Automation & Control
Deploy in factory automation to link multiple CNC machines, robotic arms, or temperature controllers to a single supervisory computer, with ESD protection safeguarding against motor noise or power fluctuations.
Retail & Hospitality Point-of-Sale
Integrate barcode scanners, receipt printers, cash drawers, and customer displays into a compact USB hub behind counters, using the DIN rail mount for tidy installation under desks or in enclosures.
Physical Profile
The hub's compact external form factor measures 5" (127 mm) wide by 1" (25.40 mm) high, with a weight of approximately 1.52 lb (688.89 g). Its low-profile design fits easily in tight spaces like server racks, control panels, or under desks, while the metal finish provides a professional, durable appearance suitable for both industrial and commercial environments.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1" (25.40 mm), 5" (127 mm), 1.52 lb (688.89 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
