Method 2: Modifying the Settings on an Instrument
This method takes advantage of a Microsoft Windows feature called Automatic Private
IP Addressing or APIPA.
APIPA allows a PC to automatically assign itself an IP address even when no DHCP
server is present to provide an address to the PC. Translated this means that by
assigning the right address to an instrument, it will talk one to one with a Windows
machine without setting an address on the Windows machine.
The address range of
169.254.0.1
through
169.254.255.254
is reserved for APIPA.
1.
Attach the instrument to a HyperTerminal link.
2.
Set the instrument addresses as follows:
IP address
169.254.0.1
Mask
255.255.0.0
Gateway
0.0.0.0 (or blank)
3.
After setting the addresses, use the
write
command to save the addresses.
The instrument will reboot and apply the new address settings.
4.
Attach a network cable between the PC and the instrument.
5.
Use the procedure
Troubleshooting Ethernet Connectivity
D-4 to check
the connection is functioning.
