Chapter 1 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.
− − Allow SQE (heartbeat) to be disabled when used with a concentrator / hub / repeater When SQE test switch is enabled, send a heartbeat signal to the attached station at the end of a transmission 1.

Chapter 2 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 6 2.
