FAQ

What is the purpose of the SQE switch?

The Signal Quality Error (SQE) switch, also known as ‘heartbeat’, enables or disables a test signal sent by the transceiver to the host’s AUI port to confirm functionality. It should be turned ON for most applications but can be turned OFF for compatibility with certain older network interface cards.

Is this transceiver compatible with 100Mbps or Gigabit Ethernet?

No, this device is designed exclusively for 10 Mbps Ethernet standards (10BASE-T, 10BASE5, 10BASE2). It will not function on 100 Mbps (Fast Ethernet) or 1000 Mbps (Gigabit) networks.

Does this transceiver require an external power supply?

No, the LE1602A is powered directly through the 15-pin AUI port from the host network device, which simplifies installation and reduces cable clutter.
