A. Introduction 
Device CME-LW01 is used for communication interface between 
Modbus and LonTalk. CME-LW01 needs be configured via 
LonWorks network tool first, so that it can perform the function on 
LonWorks network. No need to set CME-LW01 address. 
This manual provides instructions for the installation and setup for 
CME-LW01 that is used to communicate with Delta VFD-E 
(firmware version of VFD-E should conform with CME-LW01 
according to the table below) via LonWorks Network. The content 
of this instruction sheet may be revised without prior notice.

E. LEDs 
Indications 
There are three LEDs in front panel of CME-LW01. If the 
communication is normal, power LED, SP LED should be green 
(red LED means abnormal communication) and service LED 
should be OFF. If LEDs display do not match, refer to user 
manual for details.

Corrective Actions 
LED blinks at 
1/2 Hz rate 
This is the normal 
situation for an 
un-configured device 
 
LED is OFF
Bad hardware device   
Check if anything wrong with 
power supply, clock or 
Neuron chip. 
LED is ON 
continuously, 
even when 
power is first 
applied to the 
device. 
Bad hardware device 
1.  Check if anything wrong 
with power supply, clock or 
Neuron chip. 
2.  Check if there is a short 
circuit between pin 17 and 
18. 
LED blinks at 
power-up, 
goes OFF, 
then ON 
solid. 
This is the normal 
situation for an 
application-less device. 
If the device is not an 
application-less, then it could 
be memory problems or 
application code errors. A 
self-test failure can also turn 
the LED ON solid.
