The toggle switch is used to toggle the module into or out of Default Mode 
(toggle left), or to reset the module (toggle right).  In Default Communication 
Mode, the yellow ST LED blinks slowly and 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 “password00”. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

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 
if module is in default mode 
and stays ON if an input is out 
of range. 

 

Green LINK LED 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 input circuit, network, and 
power circuit are isolated from 
each other for safety and noise 
immunity.
