Setting and Installation

2.1 Setting the SQE Switch

When this transceiver is connected directly to a
repeater, the SQE function must be disabled.
Note that a 10Base-T concentrator is a repeater
unit.

SQE Test:
§ Default: enable
§ Enable: attaching the transceiver to a LAN

card in a computer, or to device expecting
the SQE test signal such as bridge or router

§ Disable: attaching the transceiver to a

hub’s or repeater’s AUI port

2.2 Installation

Because of the ET-118 compact design, it is
not necessary to connect it to another Ethernet
device via transceiver cable.

The ET-118 15-pin male connector is plugged
into the 15-pin female AUI connector on a
coax Ethernet board or other Ethernet device,
such as a repeater. Once attached, make sure
that the slide locks are properly latched. The
other end of the ET-118 features two female ST
connectors, one for transmit data and one for
receive data. These make with two male ST
connectors at one end of a duplex fiber optic
cable segment, as showing figure 2-1 and
figure 2-2.
