Chapter 6.   Troubleshooting 

If you attempt to communicate with the module and receive no 

response, first check the following: 

 

Ensure that the supplied power is within the range of +10 to 
+30 V DC.    If the supplied power is OK, then the power LED 
should be on. 

 

Ensure that the RS-485 converter provides the bias. The 
RS-485 converters manufactured by ICP DAS all provide the 
bias. If the RS-485 converter does not provide the bias, then 
you can refer to section 1.8 to open the cover to adjust the 
jumper to enable the RS-485 bias for M-7004. For M-2004, you 
can turn on the two B.R. switches to provide the RS-485 bias. 

 

When the module receives a command, the power LED is set to 
“off”.    The power LED is shown as “on” after the module 
responds.    This method can be used to check whether the 
module has received a command sent from the host. 

 

If possible, use another device to check whether the host can 
communicate with the device through the same RS-485 
network. 

 

If the host is a PC installed with a Windows operating system, 
then execute the DCON Utility to determine whether the 
module can be found.    The DCON Utility can be downloaded 
from the ICP DAS website 

http://www.icpdas.com

.    Please 

refer to Chapter 2 for details. 

 

Set the module to 

“INIT mode” and communicate with the 

module using the following settings: address 00, Baud Rate 
9600bps and no checksum.
