OmniHawk™ 4/16 Token Ring
Fiber Converter
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
withinacampusnetwork.Eventrunkconnectionsbetweenfloorsofasingle
buildingbenefitfromtheadvantagesoffiberopticmedia.In heavy industrial
settings, fiber optic media may provide the only reliable connectivity even
whenthedistancestraveledareshort.Moreover,agrowing number of work-
station interface cards now feature fiber optic connection.
TheOmniHawk™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-
gorithmwhichassuresdependablecommunications.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.

CONNECTORS, SWITCHES & INDICATORS
CONNECTORS
The OmniHawk™ has three interface connectors: a fiber optic transmitter
and receiver pair, an RJ45 jack, and a DB9 male connector.
The DB9 connector and the chassis are designed to attach directly to the
rearofaworkstation network interface card. The jack screws ensure a solid
connection.
The RJ45 connector is designed to attach directly to a hub lobe or ring out
via a CAT-5 patch cable. The RJ45 connector may attach to a ring in with a
crossed patch cable (transmit and receive pairs crossed).
Note that only one copper interface may be used at a time. Other connec-
tionsarepossible with special cables. Omnitron’s technical supportdepart-
ment can assist you with your special needs.
SWITCHES
The OmniHawk™ has two switches which control the attachment mode.
The switches are located to the right of the DB9 connector.
Both switches are placed in the UP position at the factory. The following
table explains the switch settings.
ATTACHMENT MODE SWITCH 1 SWITCH 2
Automatic Sensing Up Up
UTP/STP --> RO or Station Up Down
UTP/STP --> RI or Lobe Down Up
Self Test / Media Test Down Down
CONNECTORS
In addition to the two switches there are four LED indicators in a 2 x 2
cluster. Refer to the drawing below.

The operational modes are:
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
occurswhencopper device initiates the phantom current and thefiber optic
device initiates the fiber optic key. In Token Ring, the active insertion pro-
cess may only be directed from one direction.

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-
tomtwoLEDs will both illuminate yellow indicating that power ison 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
aremadeandthecorrespondingLED 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).
INSTALLATION TEST
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.
TheOmniHawk™installationtestfeaturewarns the installer that an initiator
hasbeenconnected to both the fiber optic interfaceandto 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.

necttheOmniHawk™ 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.
NOTE: TURN OFF THE SELF TEST / MEDIA TEST MODE TO RETURN
TO NORMAL OPERATIONAL MODES.

RUN-TIME ACTIVITY & ERROR MONITORING
During normal operation the fiber optic and copper ready LEDs provide
continuous diagnostic information. These LEDs detect and display token
ring activity.
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
itsfiber side but has not yet sensed aphantom current echoer on its copper
side.
When the OmniHawk™ connects to passive devices, the insert status LED
will always be off.
UNPACKING

SITE REQUIREMENTS
A power outlet should be available within 5 ft. of the unit. The following
power supply modules are required for the following power outlets:
MODEL POWER OUTLET
3900 110 Volt - 60 Hz
3900-2 220 Volt - 50 Hz
3910 110 Volt - 60 Hz
3910-2 220 Volt - 50 Hz
NORMAL CONFIGURATION
a. Attach the workstation or hub with the appropriate cable to the
OmniHawk™.
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.
Refer to the APPLICATIONS section for useful application information.
ALTERNATE POWER SOURCE
Some Token Ring network interface cards supply power via the DB-9 con-
nector.Compatiblenetworkinterfacecardssupply+5Von 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.
INSTALLATION TEST CONFIGURATIONS
The OmniHawk™ supports the following media test configuration.
Loopback Media Test
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
illuminategreen.Ifthefiberis partially or completely broken, the LED will be
off.
