LED status indicators

The E-DIO24-OEM has two LED indicators that indicate the status of power and host communications. The
LEDs are stacked one above the other:

The LED (top) is on when external power between 4.2 V to 5.6 V is supplied.
Power
This LED is off when the external power supply is not connected, or the input power is outside of the 4.2 V
to 5.6 V voltage range of the external supply, causing a power fault.
The E-DIO24-OEM has an onboard voltage supervisory circuit that monitors the 5 V external power
supply.

The Activity LED (bottom) is on when a valid host connection is detected.
This LED blinks when a command is received.
Both Power and Activity LEDs blink once when factory default settings are restored. Refer to
default network settings

Ethernet connector

The E-DIO24-OEM has one 10/100 BASE-T, auto-negotiation, high-speed communication port. The port
connector is an RJ-45, eight-position type that accepts CAT-5 shielded or unshielded twisted pair cable. The
maximum communication distance without using a repeater is 100 meters (328 feet). You can send your data
100 meters at data speeds of up to 100 Mbps using only one Ethernet cable connected to the network.
