Troubleshooting Information
Checking the Network
Steps to Set Proxy Notification (Microsoft Internet Explorer 5.0, 5.5)
1 From Internet Explorer, select Tools->Internet Options
2 Click the Connections tab
3 Click the LAN Settings… button under Local Area Network
(LAN) settings
4 Under Proxy server, if “Use a proxy server” is checked, click
the Advanced… button
5 Under Exceptions, add the IP address of the E5810 or a fully-
qualified domain name (such as myE5810.example.com) to the list
box called “Do not use proxy server for addresses
beginning with:”
Use a semicolon (;') to separate entries.
6 Click the OK button on the bottom of the Internet Options dialog
box to make changes active.
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 Remote IO 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 I/O 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.
