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
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.
