Ethernet connector
The E-1608-OEM has one 10/100 BASE-T, auto-negotiation, high-speed communication port. The port
connector is an RJ-45, eight-position connector. The Ethernet port accepts CAT-5 shielded or unshielded
twisted pair cable. The maximum communication distance without using a repeater is 100 meters. You can send
your data 100 meters at data speeds of up to 100 Mbps using only one Ethernet cable connected to your
computer.
External power connectors
The E-1608-OEM requires external power, and has a 1 × 2 pin, 0.1 in. pitch header labeled
W1
for an external
power connection.
The device also has a DC barrel input jack labeled J4. A compatible 5 V external power adapter (PS-5V1AEPS)
can be purchased separately
.
LEDs
The
Power
LED is steady green when external power between 3.3V to 5.9 V is supplied to the E-1608-OEM.
The
Power
LED turns off when:
power is not supplied by the external supply (make sure that the supply is fully connected to the power
connector)
the input power is outside of the specified voltage range of the external supply (3.3V to 5.9 V ), causing a
power fault
The E-1608-OEM has an onboard voltage supervisory circuit that monitors the 5 V external power supply.
The
Activity
LED is on when there is a valid host connection, and blinks when a command is received or an
analog input scan is running.
Ethernet connector LEDS
The green
Link/activity
LED on the lower left of the Ethernet connector is on when there is a valid Ethernet
link, and blinks when network activity is detected.
The yellow
Speed
LED on the lower right of the Ethernet connector is on when the transmission speed is
100 Mbps, and off when the transmission speed is 10 Mbps or there is no link.
Factory reset button
Use the factory reset button to reset network configuration settings to the factory default values.
