I have using Digi Connect ME many years. But i have facing one problem quite long time a go but now facing the same problem again.
I would like to know is it possible to change the IP address using UART? We need to automatically configurable using our own system. Is it possible to do that?
The same tx and rx pins are used for both data and configuration. You set your dtr pin to control which it is.
I use Digi Connect ME - DC-ME-01T-S
You must use telnet not hyperterminal. First find out the current IP address of your module either from your DHCP server or use the dgdiscvr.exe utility. Then from a windows command prompt, run a telnet session, for example:
telnet 192.168.0.200
Log in and then use the command I gave before. You will then be able to configure the module from the uart. You will need to study the documentation about how to use XML for the configuration.
…is it possible to change the IP address using UART?
Yes and No!
Yes is is possible to do, but not on a new or factory reset module.
You have to log in on the network side using telnet in order to enable RCI serial.
command is:
set rciserial state=on
I think you can also activate it through the web interface, but I find the telnet method quicker and easier.
Once done, you can then use RCI mode at any time by activating the DTR pin (i think?) where you have access to all of the module’s settings. Unfortunately, the command language is XML, so if you are using a small microprocessor, the task is not trivial.
