Appendix A: Troubleshooting 

 

A1. How do I restore the web password for the module to the factory 

default password? 

 

 

The instructions below outline the procedure for resetting the web password to the factory 

default value.          

Note:

 Be aware that 

ALL

 settings will be restored to the factory default values after the 

module is reset.

 

 

Step 1

 Locate the Init/Run switch that can be found on 

the right-hand side of the tM-752N module and set it to 
the

 "Init" 

position. Reboot the module to 

load factory 

default settings

 including default web password. 

 
 
 
 
 

Step 2

 Execute either the VxComm Utility or the eSearch Utility to search for any tM-752N 

modules connected to the network.  Verify that the tM-752Nhas been reset to the original 
factory default s

e

ttings. For example, the module should be shown as having the default IP 

address, which is 192.168.255.1.
