    Prior to installing and operating the ST-500 transceiver, read through this manual completely to become familiar with its content and to gain an understanding of the ST-500 features. A general working knowledge of Ethernet/802.3 networks is helpful when installing the transceiver.
  • Page 7 CHAPTER 1: INTRODUCTION The type of tap provided with the transceiver body defines one of four models of the ST-500 transceiver. The four models are: • ST-500-00 - transceiver body only (no tap included) • ST-500-01 - with non-intrusive (stinger style) Ethernet tap •...

  • Page 8: Lanview Leds

    1.1.1 LANVIEW LEDs The ST-500 transceiver has five LANVIEW LEDs that monitor network activity (transmit, receive and collision present), power status, and heart- beat (SQE) test status. These LEDs are described in Table 1-1. They serve as a useful tool to quickly diagnose physical layer problems.

    CHAPTER 2: INSTALLATION 2.3 Installation Site To install the ST-500 transceiver, a minimum area of 17.8-cm (7-in) high by 20.3-cm (8-in) wide by 10.2-cm (4-in) deep is recommended to pro- vide enough space for the transceiver, tap, and Attachment Unit Inter- face (AUI) cable connections.

  • Page 12: Installing The Transceiver Tap

    There are three types of taps that can be installed in the transceiver. To install the transceiver tap, proceed to the appropriate transceiver tap in- stallation instructions, as follows: • For ST-500-01 transceivers, go to Section 2.5.1. • For ST-500-02 and ST-500-03 transceivers, go to Section 2.5.2.

  • Page 20: Connecting The Transceiver To The Host

    2.6 Connecting the Transceiver to the Host The ST-500 Transceiver is designed to operate with Ethernet Version 1.0, Version 2.0, and IEEE 802.3 compliant systems. However, each version requires different wiring for the transceiver cable. Since cable grounding is accomplished at the host end of the cable, the correct cable must be used according to the requirements of the host equipment.
