Basic Network Connection
1. Turn off the power to the device/station on the net
work to which the MultiMode Converter will be
installed.
2. Ensure that there is no activity on the network.
3. Connect the MultiMode Converter to the fiber net
work using standard MultiMode fiber cable.
4. Connect the MultiMode Converter to the
100BaseTX network, using standard UTP cable
(terminated on both ends with RJ45 connectors).
Please note:
the fiber connections must be
matched from the transmit socket to the receive
socket.
5. Connect the 5V DC power adapter to the
MultiMode Converter, and verify that the Power
(denoted as PWR) LED is illuminated.
6. The TP and FX Link LEDs will illuminate, once all
cable connections have been properly made.
Once this occurs, please restore power to the
device/station that was powered down in step #1.
