I upgrade from V1 to V2 and my now I can't see any devices

Help!

I upgraded from Version 1 to Version 2.0.15. After completing the upgrade I only see Portal. No other devices show up on the node view.

Probably what happened is your default communication port changed.

I am guessing you were using the USB port prior to the upgrade. Try connectioning a cable to the serial port. This should fix it.

I can now see one device. What do I need to do to find the remaining devices?

Also, how do I switch my default port back to USB?

What is the MAC address of the device (Node1) you do see in Portal?

If it is 00:1C:2C:00:00:00:00:FF then the problem is that the MAC addresses of all your units have been erased. This is sometimes an issue when upgrading from V1 to V2. (It doesn't happen if you use the "Snap V1 to V2 Migrator").

To correct this problem:
1. Turn off all your devices except the one connected to the PC.)
2. Open a command line in Portal. (Select "Command Line Window" in the "View" Menu"
3. Using the command line you will reprogram the MAC address of this unit. The MAC address is found on the label on the device. The address is two lines long and typically looks something like this:

001C2C1E
C60017A0

For the above value, you would type it in the following format:

"\x00\x1C\x2C\x1E\xC6\x00\x17\xA0"

Note: Every device has must have a unique MAC address. Do not program a device with the MAC address from another device.

The command to set the MAC address is show here. Replace "YOUR MAC HERE" with the value of your device's MAC address formatted as show above. The command is case sensitive.

rpc("\x00\x00\xff", "saveNvParam", 2, "YOUR MAC HERE")

After typing this command on the command line press <ENTER>. You should not see any error message. If you do, retype the command being carefull to correctly type all information.

Now turn the power off and then back on for the device you just reprogrammed.

Finally, select "BROADCAST PING" in Portal's "Network Menu". If everything worked, you should now see this device on the "Node View"

4. Turn on one additional device. The device connected to the PC should remain ON. Repeat Step 3 for this device making sure to use its MAC address.

Repeat until all devices are showing in Portal.

I forgot to answer the second part.

To switch the default port back to the USB port, you must first determine the address of the device connected to Portal. On the command line type:

>>>Portal.connectedNetAddr

You will see a response similar to this:

"\x00\x1A\x12"

Open the "Node Info" view for the device with this address. Press "Change Configuration Parameters" and a dialog will appear.

Change the "Default Uart" from 1 to 0. The values have the following meaning: 0 - USB, 1 - RS-232.

Press OK and then turn the device off and back on. If your USB cable is hooked up, you should be all set.
