Steps to Set Proxy Notification (Netscape Navigator 6.2)
1 From the Navigator menu, select Edit->Preferences
2 Under the Category tree, click the triangle icon located to the left
of Advanced (the category should expand) and then click Proxies.
This will change the panel on the right to display the Proxies
configuration fields.
3 Under No Proxy for:, add the IP address of the E5810 or a
fully-qualified domain name (such as myE5810.example.com)
to the list. Use a comma (,) to separate multiple entries.
4 Click the OK button on the bottom of the page to activate changes
Checking Other Network Problems
There are two additional network checks you may encounter: E5810
operation hangs or SICL timeout is set to 0 (infinite)
E5810 Operation
Hangs
The E5810 has a single LAN server servicing both GPIB and RS-232
interfaces. Thus, if either interface “hangs” in an operation where a timeout
has been set to a long time period, there is no more communication on
either interface (GPIB or RS-232) until the pending transaction completes
(via normal completion, or a timeout). That is, a pending operation on the
RS-232 interface will hang GPIB operations, and vice-versa.
To avoid this, set as short a timeout as possible for
both the GPIB and
RS-232 interfaces, so the E5810 is not left in a hung situation awaiting a
pending IO operation. For example, a detached (or loose) GPIB or RS-232
cable can cause an operation to hang if timeouts are set too high.
Setting long timeouts with the E5810 is not recommended. However, if a
long timeout period is required for your programming application, you can
set the timeout with:
VISA: viSetAttribute() and VI_ATTR_TMO_VALUE attribute
SICL: itimeout()
See the Agilent VISA User’s Guide for a description of the VISA command.
See the Agilent SICL User’s Guide for Windows for a description of the SICL
command.
