Click here for more information on AS/400 & iSeries Wiring Products DescriptionThe OmniRepeater? 400FTD is an AS/400 5250 and 5250 Express data repeater and fiber converter. It converts between Twinax or UTP and fiber and provides connectivity for one 5250 host port. It supports multimode fiber for distances up to 15,000 feet and single-mode fiber for up to 30,000 feet. It supports Twinax for distances up to 5,000 feet and unshielded twisted pair (UTP) for up to 3,000 feet. It can be utilitized in fiber backbones or in fiber-to-the-desk applications. The FTD utilizes Omnitron?s Digital Phase Locked Architecture (PLA) for data detection, synchronization, retiming and repeating. This technology enables the reliable detection and synchronization of data with -2% to +4% data rate variation. It also facilitates lost-bit recovery thus enhancing connectivity reliability. Interface to the FTD is via UTP RJ11/RJ45, STP/Twinax via DB9 and fiber via ST connectors. For UTP applications, at least category 3 wiring is recommended. Lower grade wiring may be acceptable for shorter distances. Both single-mode and multimode fiber models are available. The FTD includes a built-in fiber tester. This feature eliminates the need for an expensive fiber tester and helps in installation and fault isolation. It is compatible with all of Omnitron?s 5250 fiber products, thus providing independent end-to-end cable testing. The diagnostic features of the OmniRepeater 400 FTD assist in both installation and monitoring of normal operation. Each data frame is checked and true activity and data errors are reported. They provide continuous line quality monitoring and early problem detection. The Express models operate with both 5250 and 5250 Express protocols. Each port provides data rates of 1 Mbps for standard 5250 and 2 Mbps for 5250 Express protocol OperationInputs: The OmniRepeater 400 is built around a Digital Phased Locked Architecture (PLA). This technology allows effective discrimination between true data and noise. The incoming Manchester encoded data is sampled at 16 samples per bit, which facilitates digital filtering of noise and crosstalk. A unique clock recovery facilitates the capture of data with rate variations of -2% to +4%. Inputs: Processing: Once the data is recovered and synchronized, it is processed. The processor analyzes the frame header. If a legal header is detected, the port is "marked" active and the data is allowed to flow through the repeater. . Outputs: The retransmitted data is regenerated, reclocked and lost sync bits are recovered. The data is reclocked at 50% duty cycle to eliminate clock jitter. The signal is restored to nominal amplitude and the pre-distortion logic compensates for anticipated phase shift and attenuation. Displays: True data activity and parity errors are displayed by green and red LEDs. The green activity LEDs assist in monitoring signal strength while the red Parity Error LEDs assist in monitoring connectivity quality, signal strength, impedance mismatches and reflections.
