Overview

• Proven interoperability with 5250 compatibles

• Standards-based 5250 “Star” hub distribution allows greater flexibility for adds, moves, and changes

• High reliability digital design

• Uses LAN cabling system - simple migration

• IBM iSeries AS/400, AS/36 and Remote Controller compatible

• Advanced noise filtering and signal conditioning allows the use of poorer grade cabling systems

• Automatic data rate detection

• Polarity insensitive as long as host and device polarities are the same.

• Protocol transparent design ensures future 5250 compatibility

• Meets or exceeds EIA/TIA wiring recommendations

NLynx continues to show its design leadership and commitment to the iSeries and AS/400 customers with the Gemini Express Dual Active Star Hub.

The Gemini Express (Hub) fully supports both the standard and express line speed (2Mbps) and throughput performance increases (up to 4 times faster!) available on the latest IBM iSeries AS/400e products.

The Gemini Express Star Hub transparently supports ALL features and performance gains available on the newer IBM AS/400e Advanced Series Controllers and 5250 Emulation adapters, such as TCP/IP over 5250.

The Gemini Express Hub has 2 Host Ports supporting 14 Device Ports available with either R-J11 or RJ-45 connectors. Other features include Advanced Noise Filtering, LED Port Diagnostics, Configurable UTP Pin Assignments, and a Field Replaceable wide-ranging Power Supply.
