Industrial Applications

1. SOHO and Home-Office Network Uplink Expansion

Utilizes the 5-port Gigabit capability within a lightweight plastic housing to expand standard workspace LAN access points quietly and efficiently, saving physical desk space.

Problem Solved

Resolves local Ethernet port shortages in workspace settings without introducing distracting acoustic fan noise or requiring complex software configuration.

2. Localized Electronics Test Bench Switch

Allows development PCs, diagnostic tools, and prototype boards to exchange high-bandwidth files locally using store-and-forward architecture and 1000Mbps speeds on a compact bench footprint.

Problem Solved

Ensures uninterrupted, frame-loss-free localized communications using IEEE 802.3x flow control, eliminating the need to rout multiple cables back to a central router.

3. Low-Power Retail Kiosk and POS Integration

Integrates into small-scale point-of-sale systems, automated ticketing kiosks, or digital sign displays where low voltage and low heat dissipation are essential for enclosed electronics compartments.

Problem Solved

Provides simple network splitting for multi-device kiosks powered by a low-draw 5VDC utility line, preventing enclosed cabinets from overheating.
