There are few instances where you might need to change the internal model ID for m-pod:

• After a firmware update.
• On rare occasions, the model ID is set incorrectly at the factory.
• Some m-pod models share the same hardware but are configured differently, e.g. m-pod for Neuroscan Grael and m-pod for Neuroscan 16-bit, but one is configured for 8 bits of output while the other is configured for 16 bits of output.

The Xidon utility lets you change the model ID in less than a minute. The rest of this page assumes that it is already installed.

The screenshots and steps below assume that you are using an “m-pod for Parallel Port” that is connected to a StimTracker; the steps are similar for when m-pod is connected to an RB or Lumina 3G controller.

• On your Mac or Windows computer, launch Xidon.
• in Xidon, click on the Search for Device button. Once Xidon finds StimTracker, it will display the correct model and the names of all the m-pods that are attached to it.
• Click on the Device menu → m-pod for Parallel Port  → Signal Mapping…. 

• In the list on the left side of the dialog, click to select the output line that you want to configure. The “Count” column tells you how many signals are assigned to that line.
• On the right side of the dialog, enable the signals that you want m-pod to produce on that line.
• Sometimes, a signal’s name is colored in red or purple. This is Xidon’s way of letting you know what the signal is not assigned to any output line or that it’s assigned to two or more output lines.
