FCC Information
The Federal Communication Commission Radio Frequency Interference Statement includes the following paragraph: This equipment has been tested and found to comply with the limits for a Class B Digital Device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communication. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
§ Reorient or relocate the receiving
antenna.
§ Increase the separation between the
equipment and receiver.
§ Connect the equipment into an outlet on a
circuit different from that to which the receiver is connected.
§ Consult the dealer or an experienced
radio / TV technician for help.
The user should not modify or change this equipment without written approval from company name. Modification could void authority to use this equipment. For the safety reason, people should not work in a situation which RF Exposure limits be
Page 3
exceeded. To prevent the situation happening, people who work with the antenna should be aware of the following rules:
1. Install the antenna in a location where a
distance of 6.5 cm from the antenna may be maintained.
2. While installing the antenna in the
location, please do not turn on the power of wireless card.
3. While the device is working, please do
not contact the antenna.

General Descriptions
1.1 Introduction
The fiber Optic Medium Attachment Unit provides the complete Attachment Unit Interface (AUI) to fiber optic interface. It connects to any standard IEEE802.3 Data Terminal Equipment AUI connector, and requires no configuration. It is connected through a standard AUI cable or direct connection to an Ethernet board or Ethernet device unit via the AUI port. The MAU includes the complete transmission, receiving, and collision detection, jabber timer, link test function as specified by the IEEE802.3 for use in a 10Mbps CSMA/CD Ethernet on a duplex fiber optic LAN system.
Complies with the IEEE802.3 10Base-FL
standards.
Supports up to 2000meters of duplex fiber
optic cable segment.
1.2 Features
Compact design allows direct connection
to an Ethernet board of Ethernet device unit via the AUI port.
Two female ST connectors, one for
transmitting data and the other is for receiving data.
Link-integrity test for the automatic
checking of fiber lines
Provides LEDs for a quick visual check
of individual link status, collision, Transmit, and receive.
Selectable end-of-packet SQE test

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.
