Page 8: Overview
Overview CentreCOM™ AT-200 Series Single Port Transceivers are highly reliable compact Media Access Units (MAUs) for users of Ethernet Local Area Networks (LANs). They provide the electronic and physical interface between the IEEE 802.3 coaxial cable and a Data Terminal Equipment (DTE) station. The AT-200 transceiver is available in a variety of configurations, all of which meet the transceiver compliance requirements of IEEE 802.3 and are compatible with Ethernet Version 1.0 and 2.0. -

When necessary, you can enable the SQE test using the Heartbeat switch located on the Printed Circuit Board (PCB) inside the transceiver body. This must be done without the tap body installed in the transceiver. Checking and setting the SQE/Heartbeat switch If the tap body is not installed in the transceiver (for models AT-205 and AT-206), skip to step 3. -
Page 10: Data Cabling Considerations
AT-200 Single Port Transceiver Data cabling considerations. When configuring 10BASE5 coax segments, IEEE 802.3 specifications provide the following rules to follow: MAU attachments limited to 100 per segment MAU attachments spaced at multiples of 2.5 meters (8.2 ft.) measured accurately from the cable end (50 terminator included) Segment length cannot exceed 500 meters (1,640 ft.) Worst case “end-to-end”... -

AT-200 Single Port Transceiver 11. To install the transceiver, align the opening on the transceiver body so that the diagnostic LEDs are facing you. (The transceiver is reversible front to back.) Gently guide the tap body into the transceiver opening so that the probe post and the two braid terminator posts are aligned with the three gold-colored circuit board contacts. -

The SQE/Heartbeat is factory set to the “0” (disabled) position. Unless your application calls for the heartbeat signal to be enabled, leave this switch in the “0” position. (See “Heartbeat configuration” on page 1.) Figure 4: AT-200 with N-Series Thicknet Backbone Connector (AT-208) Data cabling considerations. -
