Overview

• Up to 56 devices supported from two controllers on a single pair of Fiber Optic cable
• The only fiber optic multiplexer that supports split-polling (200% speed improvement — dual option) on enhanced AS/400 WSCs
• Direct DB25 workstation controller connection on rear panel
• Compatible with Express and standard data rates.
• Automatic data rate detection
• Advanced noise suppression on all ports
• Does not require performance-robbing PTFs to function
• Extends AS/400 ports up to 15,000' on multi-mode fiber optic cable
• Supports both “point to point” and “multipoint” applications
• Polarity insensitive as long as host and device balun polarities are the same
• Field-replaceable universal voltage power supply
• Shielded RJ45 with any active pin configuration

Get Maximum Throughput Potential with the Gemini Express Multiplexer

Decision Data?s eight-port, fiber-optic Gemini Express Multiplexer offers the unique ability to allow up to two AS/400 controller polling groups to be transmitted over a single fiber optic pair. Controller redundancy and maximum fiber optic efficiency are obtained by multiplexing four ports each from up to two separate controllers for a total device capacity of 56 ? the highest in the industry. This feature also allows all new AS/400e controllers to provide their maximum throughput potential, in either 1Mbps Optimized or 2Mbps Express mode, by transparently multiplexing the split-polling feature without requiring performance-robbing PTFs. All new IBM controllers support the split-polling feature as a means of achieving higher throughput rates, even when connected to standard legacy devices. The Gemini Express Multiplexer allows the split-polling feature to remain enabled with performance of up to 4 times greater than standard legacy 1Mbps 5250 protocol.

Eliminate Old Twinax Bricks and Twinaxial Cabling

The Gemini Express Multiplexer has eight shielded RJ45 port connections as well as a DB25 direct-connection eliminating the need for the Twinax brick and associated twinaxial cabling. Link connectivity is via ST fiber optic multi-mode connection with ability to operate in both point-to-point and multi-point ring topologies, reducing hardware requirements by up to 50%.
