When you select Probe N2 network, you are prompted for a starting and ending address. The diagnostic program scans from the starting address to the ending address trying to identify devices. For each address where a device is found, the device type ID is reported in hexadecimal (base 16). For each address where no device is found, two question marks are printed.
In this example, the starting address is 1 and ending address is 8. The only devices configured are a DX9100 at N2 bus address 1 and a UNT at N2 bus address 7.
First address to probe :1
Last address to probe :8
