Installed T3BB, was working fine, issue came up when trying to add RS485 device.
Somehow the IP address on T3BB display now reads 255.255.255.2. I have updated software, tried the T3 search function, tried connecting directly to it with isolated computer. IT says that the IP address cannot be recognized by windows, shows as invalid. Is there a way to manually do a factory reset? The buttons on the LCD display do not work either. Our IT guys are still looking for a way to access that IP address. Any help would be appreciated.
IT was able to successfully ping IP 255.255.255.2 with Linux computer. Still no way to change IP address on controller to one windows can recognize.
Havent seen that before… you could try connecting over RS485. From there you will be able to get at all the communications settings just as if you were connected over IP.
There’s no hard reset for the IP address, if it doesnt pick up an IP address from your DHCP server it will default to whatever was last successful. We test them using 192.168.0.xxx so you could give that a try on a separate sublan.
If the device is set to use a fixed IP already it will stick to that but ‘should’ still respond to global broadcase from your PC running T3000 during the scan operation. Your local environment may have broadcasts shut down in which case you could try running T3000 and a single PC on a small unmanaged hub.
You can try loading new firmware, do that in the first few seconds after power up on a separate sublan with unmanaged hub. Navigate to T3000 → Tools → Update firmware for single device which brings up the ISPTool utility.
Update, the email routing to the forum is not working normally, will cut & paste here for now:

Tried to flash controller using Com Flash with id255, com3, tried all baudrates. Reading device info times out and says connection failed. Pinging device fails. Tried with suggested ip and the one on the the controller display. Tried while unit is rebooting. Connected computer as suggested. T3 search still does not find controller.

OK, so two issues now, cannot flash the device and cannot connect over Ethernet.
Are you able to at least just connect over RS485 to any device. Confirm that so you know you have known good drivers, cable, software setup.
After power up the device will flash with two blips repeating every second or two. This is called the bootloader mode where the device powers up and checks for firmware update commands over IP and RS485. After about 15 seconds of the bootloader mode it will switch to a single blip repeating every second or so and this is the ‘Normal mode’ where the controller is doing its thing. Can you tell me if you see both the bootloader and normal mode flashing on the heartbeat LED please.
If you see only the bootloader mode and then no flashing after that you can only revive the device by cycling power and attempting to establish a firmware update using the ISPTool.
If you see the both the bootloader mode and then the normal mode after ~15 seconds after power up then you can continue trying to connect to the device over Ethernet and/or RS485. You can try on both the RS485 ports in case one is burnt out.
Search this forum for many tips, especially with Ethernet:
Disable all aux adapters like VPN and wifi.
Do your Ethernet testing using just one PC and a non managed hub.
Make sure there are no programs and/or background processes using the Bacnet and Modbus IP ports

Standing by to help out more.
You need to connect the T3BB to your PC using RS485. Once connected, you can use the T3000 software to change the device’s IP address to the one you need. This will allow you to proceed with the configuration over Ethernet afterward.
You only need the RS485 adapter to initally connect and configure the IP settings to match your environment. Once that is done you should be able to connect over Ethernet.
You will only need that RS485 adapter for future troubleshooting.
