A “sync not detected” error means that the MR software was looking for a sync trigger from that device, but didn’t find one. Most of the time, this is because of one of the following reasons:
- The sync cable for that device is not connected correctly.
- There is a cable plugged into the “Sync In” port on the MyoSync, but there shouldn’t be. (If the sync trigger is being generated for only Noraxon devices, nothing should be plugged into the “Sync in” port.). The “sync in” port is only used when triggering a recording with a 3rd party external system.
- The switch on the top of the MyoSync is flipped ot the wrong direction. The MyoSync switch should be flipped to the right in the image below, so that it is pointed toward the signal that looks like a square wave that goes from low to high, then high to low (circled in blue, below)
For a list of the specific sync settings required for each Noraxon device and details on how to set up the MyoSync, refernece the MR4 Synchronization Guide🔗.
