This CentreCOM Micro Transceiver is a 10Base-2 compliant transceiver designed to reduce Ethernet cabling costs. Compact size allows it to connect directly to the workstation, bringing thin Ethernet wiring directly to the workstation. The 10Base-2 compliant AT-MX10 and AT-MX10S transceivers use an industry-standard Ethernet transceiver chip that guarantees IEEE 802.3 compliance.On all models Signal Quality Error (SQE)/Heartbeat test can easily be enabled or disabled via an externally accessible switch. Additionally, all models have integral jabber lock-up prevention circuitry and a loopback function. This function emulates coaxial media where transmitted packets are looped back to the receive side. Local Area Network (LAN) controllers can use the loopback feature to determine if a Media Attachment Unit (MAU) is connected and operational. SQE/Heartbeat test status is indicated by LEDs on the transceiver. The AT-MX10 and AT-MX10S transceivers utilize a two-colored LED that indicates the presence of Data Terminal Equipment (DTE) power in addition to the SQE test.
