OmniRepeater™ 400
AS400/3X 5250 and 5250 Express Twinax Fiber Converter
Omnitron Systems
Technology, Inc.
FEATURES
nTwinax 5250 and 5250 Express compatible repeater
and fiber converter that functions as a twinax to
twinax repeater to extend twinax distance or as a fiber
converter to extend distance using fiber media.
nSeamlessly connects to IBM’s AS/400 and 3X local
and remote twinax controllers and workstations.
nSupports distances of 5,000 feet on twinax, 15,000
feet on multimode fiber and 30,000 feet on single-
mode fiber.
nCascadable to four units for extra long distances.
nRetiming repeater technology regenerates and
reclocks data, eliminating clock jitter and noise.
nDigital Phase Locked Architecture provides
acquisition of data rates of 1 Mbps for 5250 or 2
Mbps for 5250 Express (-2%, +4%), resulting in
high immunity to noise and crosstalk.
nClear display and software independence make
installation and monitoring intuitive and easy.
nSupports single-mode and multimode fiber.
DESCRIPTION
The OmniRepeater™ 400 is an IBM 5250 and 5250 Express

The host connects to the OmniRepeater via twinax. When used
as a twinax repeater, the OmniRepeater connects the far end via
twinaxandcandaisychainuptosevenworkstations.Whenused
as a fiber converter, it converts the end device back to twinax via
a second OmniRepeater, or directly to twisted pair via a fiber to
twisted pair star.
The OmniRepeater diagnostics detect and display true port
activityandparityerrors.Theportsaremonitoredforvalidframe
header patterns which are displayed via green Activity LEDs.
The data is analyzed for errors; a detected error is displayed via
red Parity Error LEDs. These features assist in installation and
monitoring of the OmniRepeater operation.

OPERATION
Inputs:TheOmniRepeater400isbuilt aroundaDigital Phased
Locked Architecture (PLA). This technology allows effective
discrimination between true data and noise. The incoming
Manchesterencodeddataissampledat16samplesperbit,which
facilitates digital filtering of noise and crosstalk. A unique clock
recoveryfacilitatesthecaptureofdatawithratevariationsof-2%
to +4%.
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
greenandredLEDs.ThegreenactivityLEDsassistinmonitoring
signal strength while the red Parity Error LEDs assist in
monitoring connectivity quality, signal strength, impedance
mismatches and reflections.

In the second case, the OmniRepeater (d) converts the twinax data
to fiber and then back to twinax via a second OmniRepeater (e).
In the third case, twinax is converted to fiber (g) via the
OmniRepeaterand then to twisted pair via an OmniMux™ (h)
which delivers it to the workstations (k).
