The push-button is used to toggle the module into or out of Default Mode.
In Default Communication Mode, the module assumes a fixed static IP
address of “128.1.1.100”, a default subnet mask of “255.255.255.0”, a default
username of “User”, and a default password of “password”. To activate it,
hold down the DFT button on the front panel for five seconds (until the ST
LED blinks on/off slowly. To disable this feature, hold the DFT button for
another five seconds or until the ST LED stops blinking.
MOUNTING AND
DIMENSIONS
Unit mounts to “T” type DIN
rails (35mm, type EN50022).
Units may be mounted side-
by-side on 1-inch centers.
WARNING: IEC Safety
Standards may require that
this device be mounted within
an approved metal enclosure
or sub-system, particularly for
applications with exposure to
voltages greater than or equal
to 75VDC or 50VAC.
CONTROLS &
INDICATORS
Green Run LED is ON if power
is on and will blink in “wink” ID
mode.
Yellow ST LED blinks ON/OFF
slowly if module is in default
communication mode, and
blinks rapidly if a watchdog
timeout has occurred.
Green LINK LED is ON if auto-
negotiation has successfully
established a connection.
Yellow ACT LED signals PHY
network Activity (busy).
ISOLATION BARRIERS
Dashed Lines denote isolation
barriers.
The I/O circuit, network, and
power circuits are isolated
from each other for safety and
noise immunity.
