Troubleshooting LAN Interfaces

For example, if the IP address of your PC is 155.139.103.152 and the

instrument address is 169.254.58.10, the two devices are probably on

different subnets. To add the instrument to the subnet for the PC, use

one of the following:

! route is lost when the PC is rebooted

route add 169.254.58.10 155.139.103.152

! route persists when the PC is rebooted

route -p add 169.254.58.10 155.139.103.152

Checking Proxy

Settings

A proxy is a service running on a computer that takes an information request

from another computer and passes the request on as if the request was its

own. Typically, many companies use proxies to control access from their

internal network to the external Internet.

In some situations, you may not be able to communicate with the instrument

if you are using a proxy server. Typically, the web page will time out because

the requested address is not accessible by the network, although the correct

IP address or hostname is entered into the web browser address field.

To fix this communication problem between the web browser and the

instrument web server, the browser must be informed that any requests to

the instrument should

not utilize a proxy.
