GENERAL DESCRIPTION
The OmniRepeater 400 is an IBM 5250 compatible Repeater and Fiber Converter/
Modemdevice that providestrue data repeatingand media conversionfunctionality.
It provides re-timing, reshaping and regeneration of 5250 data. As a media
converter it provides modulation and conversion from/to twinax anda fiber (both
single and multimode). The following models are discussed in this manual:
STANDARD EXPRESS DESCRIPTION
2651 2661 Twinax to Twinax and Fiber
2653 2663 Twinax to Twinax Only
The OmniRepeater 400 may be used in pairs to convert from fiber to twinax and
back, or in combination with a fiber star which will provide direct distribution of
5250 data to individual devices.
The OmniRepeater 400’s diagnostic features make it easy to install and maintain.
It detects and reports true data activity, line quality and parity errors. This is
accomplished by individual port monitoring and searching for legal sync and frame
header patterns. Upon detection of a valid frame pattern, a per port green LED
indicator displays the detected activity. This feature assists in installation and in
the detection of potential line problems. The port data is analyzed for correct
parity, and errors are indicated by a red LED. This feature facilitates the continuous
monitoring of signal and line quality.
The OmniRepeater 400 utilizes a Digital Phase Locked Architecture. Combined
with its repeating, regenerating and reshaping features, it delivers an unmatched
level of performance and reliability. The Data Frame Regeneration and Sync Bit
Reconstruction features facilitate the configuration of the OmniRepeater400 with
other Omni 400 series products for complex site configurations.

CONNECTING THE HOST SIDE
Twinax
When installing the twinax host connection, the standard IBM twinax cable
should be connected to the Host/Device port of the OmniRepeater 400 unit.
Observe and monitor the port’s Activity green LED for at least 10 seconds. The
LED blinking indicates that the host is attempting to poll the devices connected
to it and that the host link quality is adequate.
No LED blinking within 10 seconds might indicate a faulty or miswired cable, too
long a cable run, or an incompatible balun (different pin configuration). A red LED
blinking might indicate either an impedance mismatch (too many twinax segments,
poor cable quality), or too long a cable distance.
CONNECTING LINK PORTS
Once the host connection is established and the host Activity LED is blinking, Link
port can be connected. If the unit is to be utilized as a Fiber Converter/modem,
Link 0 should be utilized. If the unit is to utilized as a Twinax repeater, Link 1
should be utilized. The unit will self-sense and configure itself for the appropriate
operation automatically based on the data flow.
Operation as a Twinax Repeater
Connect devices on the Link 1 side via standard twinax or cascade to another
OmniRepeater 400 or an OmniStar 400 for actual UTP device connectivity.
Operation as a Fiber Converter (Host End)
Connect both the fiber Link 0 connectors at the host end, notice and record the Rx
and Tx connections. These will need to be crossed at the distant end.
Operation as a Fiber Converter (Distant End)
Connect both fiber Link 0 connectors from the host end. Make sure to connect
theRx host cable to the Tx distant connector and the Tx host cable to the Rx
distant connector. Link 0 Activity LED should start to indicate host polling
approximately each 10 seconds. If no Activity is observed, fiber cables might be
defective or not connected properly.
Connect Twinax Host/Device port to devices, and make sure to properly terminate
the last device. When a device is connected, a green LED should indicate activity
and device should display a sign-on screen or device on-line status.
If still no LED blinking is observed within 20 seconds, that might indicate faulty or
mis-wired cable, or too long a cable run. If the red LED blinks, that might indicate
either an impedance mismatch, missing termination, or too long a cable distance.

OPERATION
Inputs
The OmniRepeater 400 is built around the Digital Phase Locking Architecture. It
allows monitoring and processing of data signals at each individual port, thus
discriminating between true data and noise. The incoming Manchester encoded
data is oversampled at a rate of 16 samples per bit cell. This sampling rate is
instrumental in the digital filtering of noise. A unique clock extraction technology
utilizing dual clock oscillators facilitates the synchronization and frequency locking
from 980 Khz to 1.04 Mhz.
Processing
Once the data has been recovered and synchronized, it is processed internally
for verification of legitimacy. The processor analyzes the frame header; it expects
at least 3 sync bits followed by a Code Violation. When legal frame header is
detected, the port is “declared” active and the data frame is accepted for
retransmission.
Outputs
The retransmitted data frame is fully regenerated and reclocked. Any lost sync
bits are regenerated; the data is reclocked at a 50% duty cycle, thus completely
eliminating the effect of any accumulated phase shift or jitter. The regenerated
signal amplitude is restored to its nominal value and the pre-distortion logic pre-
compensates for anticipated phase shift and attenuation.
Displays
True data signal activity is displayed by a per port green LED. The data parity
errors are displayed by a red LED. While the Activity LED assists in detecting
connectivity, signal strength and polarity inversion problems, the Error LED assists
in detecting connectivity quality, signal strength, impedance mismatches,
discontinuities and signal reflection problems. As such, these two indicators help
in the installation and maintenance of the repeater.
INSTALLATION
Unpacking
a. Visual Inspection – Before unpacking, a visual inspection should be conducted
in order to detect any physical damage to the equipment. Any evidence of the
damage should be noted and reported immediately.
b. Unpacking – Place shipping container on a flat surface, cut straps or tape,
opentop. Take outeach item carefully and place securely on a clean flatsurface.
Return all packing material into a container (foam, boxes, etc.), close and
store away for future reuse.
c. Inspection – Inspect each item for any apparent damage, any evidence of
damage should be noted and reported immediately.

Mounting
Secure the OmniRepeater 400 chassis to either a flat surface (if tabletop) or to a
standard 19” rack if rack-mountable.
Power-Up
In order to minimize the possibility of accidental power shut off to the
OmniRepeater 400, no power switch has been designed into the product.
Special care must be taken when applying power to the OmniMux unit.
WARNING
The OmniRepeater unit does not have a power switch,
so extra care must be taken in powering the unit.
Always plug the Power Adapter into the back of
the Mux unit first. This is in order to prevent
damage to the Mux unit and to prevent potential
shorts, sparks, and fire hazards.
Verify that the power supply voltage (by reading the label on each power adapter unit)
is consistent with the facility’s line voltage (115/230 Volts), and that the Power
Adapter plug fits in the outlet.
Plug the power adapter’s cable connector to the appropriate matching connector
in the back of the OmniRepeater 400.
Plug the power a dapter into the wall outlet. Observe that all LED’s light up for
approximately 0.5 seconds. After 0.5 seconds, all should extinguish except the
yellow power LED; It stays On.
d. Content – Review the content; the following items should be included:

e. Please note any missing items or discrepancies and report them
immediately.
SITE REQUIREMENTS
