Allied Telesis AT-210TS-05D Micro Transceiver

Product Dimensions：

The Allied Telesis AT-210TS-05D is a legacy high-performance Micro Media Converter and transceiver designed to bridge the gap between different network media types. Specifically, it converts 10Base-T (Twisted Pair) signals to AUI (Attachment Unit Interface), allowing older networking hardware to connect to modern Ethernet infrastructure.

Product Detailed Description

The AT-210TS-05D belongs to the Allied Telesis “CentreCOM” series. It is a compact, “plug-and-play” device used to adapt networking equipment that only features an AUI port (common on older routers, hubs, and workstations) to a standard RJ-45 Ethernet network. The “05D” designation refers to its specific power and design revision, optimized for low power consumption and reliability.

Technical Parameters

Product Advantages

• Micro Size: One of the smallest transceivers in its class, designed to plug directly into the AUI port without obstructing adjacent ports or requiring extra mounting hardware.
• Bus-Powered: It draws power directly from the host AUI port, eliminating the need for bulky external AC adapters and messy cabling.
• Diagnostic LEDs: Built-in LEDs provide immediate visual feedback on link status and data traffic, making troubleshooting fast and simple.
• SQE Control: Includes a user-accessible switch to enable or disable the Signal Quality Error (Heartbeat) test, ensuring compatibility with a wide range of legacy controllers.
• Durability: Built with a rugged enclosure suited for industrial and commercial environments.

Important Considerations & Precautions

• Speed Limitation: This is a 10 Mbps device. It will not operate on Gigabit or Fast Ethernet (100Mbps) ports unless those ports are capable of auto-negotiating down to 10Base-T.
• SQE Settings: Most modern hubs and switches require SQE to be Disabled. However, some older bridges and routers require it to be Enabled. Incorrect settings can cause “collision” errors.
• Polarity: The device features automatic polarity correction, but if the “Polarity” LED is lit, it indicates the wiring of the twisted pair is swapped (though the device will still function).
• Hot-Plugging: While generally robust, it is safest to power down the host equipment before attaching the AUI transceiver to prevent electrical surges.

Product Applications

• Legacy System Integration: Connecting vintage industrial computers, older CNC machines, or legacy Unix workstations to a modern local area network (LAN).
• Industrial Networking: Used in plants where older PLC racks or control systems only feature 15-pin AUI communication ports.
• Network Testing: Utilized by network engineers as a “bridge” tool to diagnose older segments of a network infrastructure.
• Education & Labs: Providing connectivity for legacy hardware in research or educational environments where specific software only runs on older architectures.
