# MAC/IP detection

If a module communicates with B3 via TCP/IP, you must know its MAC address to define it in B3. This MAC address is used as the B3 module identifier.

To connect to a module for setup and debugging using Putty or WinSCP you must know its IP address.

If the IP is not known, then it can be detected using network scanners. 

One of the network scanners that can be used is Advanced IP Scanner that can be downloaded from <https://www.advanced-ip-scanner.com/>.

There is a user guide for the scanner at <https://www.advanced-ip-scanner.com/help/>.

Here are the examples of different types of B3 equipment found by the scanner:
