while providing superior noise and crosstalk immunity.
The Express models operate with both the 5250 and 5250 Express protocols. Each port provides data rates of 1 Mbps for standard 5250 and 2 Mbps for 5250 Express protocol.

OPERATION
Inputs: 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
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
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.
SAMPLE APPLICATIONS
The following picture depicts three typical applications of the OmniRepeater 400:
In the first case, the host (a) twinax signal is repeated and reclocked by the OmniRepeater (b) and workstation distance from the host is extended to 10,000 feet (c).
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 OmniRepeater and then to twisted pair via an OmniMux™ (h) which delivers it to the workstations (k).
