Yes, I set the unique IP address for T7511 and T3511

I can see T7511 and T3511 in TSensor program ,but  can't show in www page.


I have P8541.

I have set P8541 in TSensor Program and it can show in www page.

I have set  T3511 and T7511 as same as P8541….

But T3511 and T7511 can’t show on www page.

Could you tell how I can do?

Check if the www is enabled.
If sensors are in other subnet, don't forget to set gate IP and netmask.
Disable firewall ( only for test)

If this doesn't help, what is the error message in your web browser? What is the sensors IP, gate, netmask settings? What is your PC network settings?

I suppose, your company netmask is 255.255.255.0. Set netmask in sensors to 0. The default sensors www port is 80.
What are the IP's of others sensors? What is your PC IP (ipconfig command)? Please report back.

Don't change the www port.
Set unique IP address for all your sensors. report back.

I think, the problem is in your proxy server settings. ( It could be long time for ARP cache, or something else...)
You have a few possibilities, how to test the T3511:
1. Set to T3511 by that time unused IP and try to connect again.
2. Enable in your web browser choice "Don't use proxy for local connections"
3. Connect the T3511 directly with crossed cable. Don't forget manual set IP on your computer.
4. Try to delete your ARP table

arp -d

On your computer you can delete ARP table from command line (Start/run/cmd) by these presents command:

arp -d

This command erase ARP table only on your computer, not on servers and others net devices. For more information about ARP protocol please visit http://en.wikipedia.org/wiki/Address_Re … _Protocol, or contact your administrator.
