INSTALLATION 

Set Switches

Two (2) switches are located on the top of the transceiver.

SQE Off/SQE On: Selects SQE test function.  Set

to SQE On when connecting to IEEE 802.3
compliant repeaters.  Set to SQE Off when
connecting to other devices. 

HDX/FDX: Selects either half-duplex (HDX) or full-duplex (FDX) data

transmission. Set according to network installation.

Install Cable

NOTE: See page 6 for cable specifications. 

1.

Locate or build 10BASE-FL compliant cables with male two-
stranded TX to RX connectors at both ends.

2.

Connect male TX and RX cable connectors at one end of cable to
TX and RX female connectors, respectively, on transceiver.

3.

Connect male TX and RX cable connectors at other end of cable
to RX and TX connectors of 802.3 compliant fiber device..

Connect to Power

The E-FRL-MC04 is powered through the AUI connection.
