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

rear of a workstation 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-

tions are possible with special cables. Omnitron’s technical support depart-

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.

In addition to the two switches there are four LED indicators in a 2 x 2

cluster. Refer to the drawing below.
