Configuring the MDC-2
The MDC-2 is normally shipped pre-configured for most applications. Actual device configuration is
beyond the scope of this manual and is more properly covered in the mist™ Mesh Network Operator’s
Manual. Configuration is done using mist Network Management Protocol (MNMP) commands. MNMP is
analogous to standard Internet Simple Network Management Protocol (SMNP).

Configuration and software upgrades are performed over-the-air using the mist™ Mesh Network.
4.1 Resetting Device Parameters
When a device is not joined to a mist™ mesh network, over-the-air configuration management is not
possible. In some cases the node cannot rejoin the network because of prior erroneous configuration
changes made using MNMP. Some MNMP variables might be preventing the device from joining. For
this and all other cases where a device must be reset to factory parameters while off the network there
is a manual method:

this and all other cases where a device must be reset to factory parameters while off the network there
is a manual method:
1. Apply the magnet to the side of the MAT for 4 seconds. There will be 1 second green LED blink in
the beginning of these 4 seconds.
2. Remove magnet for 4 seconds. As soon as you remove the magnet you will see sub-second
green and then orange blinks.
3. Reapply magnet for 1 second you will see sub-second green and then orange blinks again. Then
after 1-2 seconds pause you will see orange LED going solid for ~10 seconds. This is an indication
of the successful NVS reset.

4. If it did not work wait for 10 seconds and repeat the whole sequence.
This procedure restores all device parameters to their software defaults and it causes the device to
reset. This procedure does not erase the persistence memory storage.

5 Troubleshooting
5.1 Mesh Network Issues
The majority of MDC-2 issues/questions are related to network connectivity. If the MDC-2 is blinking
green, the device is seeing and has joined a valid, authenticated mesh network. But if messages from the
device are not being received, this likely means that the gateway device that is operating the mesh
network is not communicating to your Device Management Center (DMC). Remember that a MDC-2
joins the first network that it sees, but the tag will continually look for a “better” network. Also
remember that messages pass from tag to tag on the way to the gateway. If tags are physically removed
from the network they may carry messages with them.

The best way to resolve a mesh network connection issue is to remove the tag in question to an
isolated, known good mesh network.

5.2 Battery Issues
The normal MDC-2 configuration will yield a battery life of at least 1 year per battery. The MDC-2 is
normally equipped with 3 Lithium A-Cells and so a 3+ year battery is expected. Extended duration high
temperature operation (50C or greater) will reduce battery life. Extended duration low temperature
operation (0C or lower) will reduce battery life.
