TCW241 with same MAC address was created by maurice
Dear support,
I've restored a configuration taken from a TCW241 on different other units.
After I've restored configuration I've changed IP addresses to different one for each unit.
After that all my devices has same MAC address and I cannot connect them to the same network because of this.
What can I do?

The back/restore functionality is very powerful and flexible. It can be used in a variety of cases – archive for a single controller, multiplication of controller’s settings, etc.
For this reason, we accept that there isn’t “the right” way of working of back/restore.
If you don’t need to overwrite some parameter you can remove it from XML file. It is also possible to remove a whole section.
Editing of XML file can be done with standard Notepad.
For example:
The standard file beginning of backed file looks like:
<?xml version="1.0" encoding="UTF-8"?>
<TCW220>
                <NET>
                                <IP>192.168.50.5</IP>
                                <MASK>255.255.255.192</MASK>
                                <GATE>192.168.50.1</GATE>
                                <DNS1>192.168.50.1</DNS1>
                                <DNS2>0.0.0.0</DNS2>
                                <DEFIP>192.168.50.5</DEFIP>
                                <DEFMASK>255.255.255.192</DEFMASK>
                                <MAC>D8-80-39-2D-19-BB</MAC>
                                <NBN>TCW220         </NBN>
                                <FL>0x80</FL>
                                <SEBR>0</SEBR>
                                <LINK>0x00000000</LINK>
                </NET>
                <SYS>
                                <ITEN>0x0F</ITEN>
                                <HREF>1</HREF>
                                <XAU>0x00</XAU>
                                <WAU>0x00</WAU>
                                <HPORT>80</HPORT>
                                <TUNIT>0x00000000</TUNIT>
                                <USER>admin</USER>
                                <PASS>admin</PASS>
                </SYS>
                <NTP>
                …..


If you remove the section NET, the beginning of file will look like:
<?xml version="1.0" encoding="UTF-8"?>
<TCW220>
                <SYS>
                                <ITEN>0x0F</ITEN>
                                <HREF>1</HREF>
                                <XAU>0x00</XAU>
                                <WAU>0x00</WAU>
                                <HPORT>80</HPORT>
                                <TUNIT>0x00000000</TUNIT>
                                <USER>admin</USER>
                                <PASS>admin</PASS>
                </SYS>
                <NTP>  
                                                …..



In this case Network setting will be not changed after restore on the target device.

The Solution:
1. To choose one controller for the original.
2. To arrange right settings.
3. To make back of settings.
4. To edit XML file with Notepad, removing NET section.
5. To arrange factory default for all other controllers. This will return their factory network settings, including MAC address.
6. To restore the modified back file to all controllers.
