USER’S MANUAL
GENERAL DESCRIPTION
The OmniHawk™ 4/16 Token Ring fiber converter provides a solution to
heterogeneous Token Ring media environments. Conversions between
copper (CAT-5 or Type 1) and fiber optic interfaces are required in most
modern Token Ring installations.
Fiber optic cabling is the media of choice for connecting separate buildings
within a campus network. Even trunk connections between floors of a single
building benefit from the advantages of fiber optic media. In heavy industrial
settings, fiber optic media may provide the only reliable connectivity even
when the distances traveled are short. Moreover, a growing number of work-
station interface cards now feature fiber optic connection.
The OmniHawk™ is packaged for a wide variety of media conversion appli-
cations. It can be wall mounted, rack mounted, or attached directly to the
DB9 connector of a workstation.
ALWAYS CONNECT
The OmniHawk™ is specifically designed with an intelligent connection al-
gorithm which assures dependable communications. Whether it is attached
to passive or active devices, the OmniHawk™ will always make a good
connection. The fiber optic interface adheres to the IEEE 802.5j specifica-
tion for fiber optic attachment.

APPLICATIONS
The following drawing illustrates three different applications of the
OmniHawk™.
1. AUTOMATIC SENSING
2. UTP/STP —> RO or STATION
3. UTP/STP —> RI or LOBE
The power / error LED turns red when an attachment error occurs. An error
can only occur when attaching to active devices (devices which signal for
insertion with phantom current or the fiber optic key). The error condition
occurs when copper device initiates the phantom current and the fiber optic
device initiates the fiber optic key. In Token Ring, the active insertion pro-
cess may only be directed from one direction.

DIAGNOSTIC FEATURES
The OmniHawk™ diagnostic features make it easy to install and maintain.
There are four levels of diagnostics: Power-On LED Test, Self Test / Media
Test, Installation Test, and run-time ready and error monitoring.
Application A shows an STP workstation connecting via its DB9 connector
directly to one OmniHawk™, which is connected to a second OmniHawk™
via fiber optic cables. The last connection to the hub is made via a standard
CAT-5 patch cable.
B. Fiber optic Workstation to hub (RJ45)
Application B shows a fiber optic workstation connecting to an OmniHawk™
vi its fiber optic cables. The OmniHawk™ connects to the hub via a stan-
dard CAT-5 patch cable.

POWER-ON LED TEST
Every time power is newly applied to the OmniHawk™ the LEDs will flash
through all possible colors to give the user the assurance that other diag-
nostic information may be correctly interpreted. The LEDs will flash all yel-
low, then either green or red. After that, the LED test is over and the LEDs
will illuminate according to the mode (as set by the switches) and the cur-
rent media connections.
SELF TEST / MEDIA TEST
The self test / media test ensures that the OmniHawk™ is fully operational.
Testing occurs when the switches both set to the DOWN position. The bot-
tom two LEDs will both illuminate yellow indicating that power is on and that
the unit is in the test mode. The testing checks both the data passing capa-
bility of the OmniHawk™ and the physical continuity of the media. For both
fiber optic and copper media test data is looped back to the OmniHawk™.
When a looped back fiber cable is connected from the transmit (TX) to the
receive (RX) fiber optic connectors, the fiber optic ready LED lights green.
When a CAT-5 patch cable is connected from the OmniHawk™ to an un-
used lobe of a hub, the copper ready LED lights green. If good connections
are made and the corresponding LED does not illuminate, then the media is
broken. This CAT-5 cable used in this test may be inserted into an operat-
ing hub since the OmniHawk™ will not assert phantom current during the
test mode (and consequently will not enter the network).
To test the integrity of copper patch cables and any intervening baluns con-
nect the OmniHawk™ to an unused lobe of any powered hub. If the cable is
unbroken, the copper ready LED will light green. If the cable is broken, the
LED will be off.
Note that the power / error LED and the test mode LED will both be yellow.
INSTALLATION TEST
NOTE: TURN OFF THE SELF TEST / MEDIA TEST MODE TO RETURN
TO NORMAL OPERATIONAL MODES.
The OmniHawk™ tests for proper installation and lights the power / error
LED red if a wrong connection is made. This check will only be made when
the connecting devices are stations and/or active hubs. Among active de-
vices, there are initiators and echoers. An initiator is a device that either
sends phantom current or the fiber optic insertion key. An echoer is a de-
vice that receives phantom current or the fiber optic insertion key.
The OmniHawk™ installation test feature warns the installer that an initiator
has been connected to both the fiber optic interface and to the copper inter-
face. Since it doesn’t make sense to connect two ring out (RO) trunk lines
together, the power / error LED warns of this condition by lighting red.

RUN-TIME ACTIVITY & ERROR MONITORING
SITE REQUIREMENTS
During normal operation the fiber optic and copper ready LEDs provide
continuous diagnostic information. These LEDs detect and display token
ring activity.
A power outlet should be available within 5 ft. of the unit. The following
power supply modules are required for the following power outlets:
The insert status LED informs the user of the insert status of the fiber optic
and copper media. This LED lights green when both the active signaling
fiber optic and copper devices have successfully reached insertion.

The insert status LED flashes when the OmniHawk™ has received phan-
tom current on its copper side but has not yet achieved insertion on its fiber
optic side, or conversely, when the unit has received the fiber optic key on
its fiber side but has not yet sensed a phantom current echoer on its copper
side.

NORMAL CONFIGURATION
a. Attach the workstation or hub with the appropriate cable to the
OmniHawk™.
When the OmniHawk™ connects to passive devices, the insert status LED
will always be off.
b. Plug the external power supply into the appropriate AC wall outlet.
c. Plug the power jack into the OmniHawk™ power connector.
f. The LEDs will flash during their self test, then settle according to the
current connection status.
UNPACKING
a. Visual Inspection - before unpacking, a visual inspection should be con-
ducted in order to detect any physical damage to the equipment. Any
evidence of damage should be noted and reported immediately.
Refer to the APPLICATIONS section for useful application information.
b. Unpacking - place shipping container on a flat surface, cut straps or
tape, open top. Take out each item carefully and place securely on a
clean flat surface. Return all packing material into container (foam, boxes
etc.), close and store away for future re-use.
ALTERNATE POWER SOURCE
Some Token Ring network interface cards supply power via the DB-9 con-
nector. Compatible network interface cards supply +5V on pin 3 and ground
on pins 2, 4, 7, and 8. When power from the network interface card is avail-
able, the OmniHawk™ will use that power and the external power supply
may be disconnected.
c. Inspection - Inspect each item for any apparent damage, any evidence
of damage should be noted and reported immediately.
d. Content - Review the content; the following items should be included:

INSTALLATION TEST CONFIGURATIONS
The OmniHawk™ supports the following media test configuration.
Loopback Media Test
Please note any missing items or discrepancies and report them imme-
diately.
To test the integrity of fiber optic media connect the fiber optic patch cable
in a loopback fashion (i.e., one end in the transmit port and the other in the
receive port). If the fiber is unbroken, the OmniHawk™ fiber ready LED will
illuminate green. If the fiber is partially or completely broken, the LED will be
off.
