I am having a problem of interfacing the E5071B with the external computer (operating system-Windows XP) using LAN interface (University Network). Interfacing using
GPIB using is working fine. When I use the Agilent Connection Expert to
find out the instrument through LAN, it is giving error of "Connection
request rejected or port not found on this host". Could you please help me out to resolve
this problem?

Please note that I have tried according to the manuals and also used "How do I configure my Agilent IO Libraries Suite 14 to communicate with my Agilent ENA Network Analyzer via LAN?" which I got it from the Agilent website., still the problem is not resolved yet!

Please note that "Instrument web interface.â€ is not working through the VNC sever.

No one else has this question

A few questions regarding your setup:

What type of connection are you wanting to setup SICL-LAN (Remote GPIB) or Sockets? In your IO Libraries, does any appear under "TCPIP0"? If so, and you are trying to use SICL-LAN (VXI-11) then you will need to create a new TCPIP interface (e.g. TCPIP1) and use this interface for the Remote GPIB interface.

Also, what version of the IO Libraries Suite are you using? If you are using 14.1, please make sure that that you add patch 2 or upgrade to 14.2 as there was a bug associated with SICL-LAN communication with 14.1 without the patch.

What is enabled under System->Misc Setup->Network Setup, SICL-LAN or Telnet? If both are enabled then Sockets is the dominant communication method. If you wish to use SICL-LAN then please only have this one set to "ON".

Also, please make sure that you can ping the ENA. If you cannot then there is no hope of getting an actual connection. If not, this could be due to a firewall blocking the port or the network settings on the ENA not being set properly. First step would be to try disabling the Windows Firewall (under Control Panel -- if enabled) on your PC.

Many thanks Danzy for your prompt reply. I have tried both connection types SICL-LAN (Remote GPIB) & Sockets, but still I am problem with the LAN interfacing.

I am using 14.2 IO Libraries Suite. I have enabled SICL-LAN and disabled the Telnet.

I could Ping the VNA from external PC & Visa-versa. And also I have disabled the firewall of the external PC.

When I use the Socket type connection and identify the instrument using Agilent Connection Expert VNA returns â€œRFB 003.008â€ which is strange (Please find the attached error image).

Earlier the web interface was working fine but suddenly it stopped working (Please find the attached error image).

It would be really appreciated if you could help me out to resolve these problems (LAN interface & Web interface) as soon as you could? Thanks.

For the sockets based communication please use socket port 5025. Would you mind changing this and seeing if this works for you?

Port 5800 is the typical port for VNC. Try restarting and then seeing if the web server and sockets communications will now work.

Also are you signed into the ENA as the standard user account "agena" or a defined account?

Thanks for you reply. I have tried socket number 5025, but still having the same problem.

I have restarted and still the web interface as well as the LAN interface is not working.

I have signed into the ENA as defined account.

Could you please help me out to resolve this problem? Thanks

Some of what I am going to recommend here will require removing many of the other settings that you have already set up. During all, please verify that all ports that you will be communicating through are open in any firewalls. The typical ports for SICL-LAN communication are 111 and 1206.

ENA-L Steps:
- Go to System->Misc Setup->Network Setup
- Verify that Telnet is turned off (Sockets will not work) and Verify that SICL-LAN is turned on
PC Steps:
- Open a command prompt and attempt to ping the ENA-L
- Open Agilent Connection Expert (Start->Programs->Agilent IO Libraries Suite->Agilent Connection Expert)
- Remove any interfaces that you have created under TCPIP0, you can right click on any instruments under it's tree and select delete
- Click on "Add Interface" on the main toolbar and select "Remote GPIB Interface"
- Enter the "hostname" or "IP Address" of the ENA-L that could be successfully pinged
- For the entry titled "Interface name on remote host" enter "hpib9"
- Click "Test Connection". If everything is working, then you should be able to successfully open the connection
Fallback Steps (ENA-L System Recovery)
- Follow the steps in the ENA-L User's Guide to complete a system recovery. I have seen cases where recoverying the ENA-L will correct problems such as this as some of the lower level drivers my become unregistered.

These settings are done by default. The key would be to verify that your PC has access to these ports as some software or hardware firewalls may block these ports. You may consider contacting your local Agilent support group for much deeper debug, although the easiest and least time consuming method will be the System Recovery. Since you have other systems that do work, you may connect one of the other systems to the PC associated with the "trouble" system and try to communicate via SICL-LAN. If the PC works, then you probably need to recover the ENA, if not you may want to work with your IT group to determine what software that may be installed on your PC is blocking communication with the ENA.
