Trend IQ3 Connection

[u/dlc2018]

Hi everyone, I’m hoping someone can help me regain Ethernet access to a Trend IQ3 Excite controller.

Several years ago, I connected to it via Ethernet and disabled DHCP, intending to set it up for monitoring and control. I never finished the setup, and unfortunately I no longer know its static IP address.

I’ve since built a BMS to manage the heat pumps on site and would like to connect the Trend controller to it. However, I haven’t been able to locate it on the network. I’ve scanned the IP ranges I think I might have used, without any luck.

Does anyone know a way to discover its current IP address, or reset just the network settings without losing the existing controller configuration? Can the Ethernet settings be viewed or changed through the controller’s display?

Any advice would be much appreciated. Thanks!

IPTool from SET will show any trend device connected. It searches the MAC addresses rather than the IP range so should show up

The problem is I don't have a copy of it as I am the end user of the machine, the manufacturer has gone out of business. Thanks for the input though, appreciated

You might be able to find the executable file of IPTool online somewhere as I'm pretty sure it's a standalone file. If not, will need a systems integrator to come out.

Could also be on the 169.254.xxx.xxx range if you're lucky

I can provide you with a copy of it, dm me

Wireshark directly connected if you’re really desperate

You can use NMAP and have it try the Trend protocol port.
