When operating more than 1 sensor, there needs to be 1 electronics module configured as a master and the remaining electronics modules configured as slaves. The master electronics module distributes the modulation signal to the slave electronics modules. More information about the modulation signal can be found on the QuSpin website here:

Send 113 for master configuration or 114 for slave configuration. Type the number in the field to the right of the [Load All] button and press [Load All] to send a command to all connected sensors. Or alternatively, send a command to a specific sensor by selecting it in the drop down menu and typing the command number in that corresponding field and then pressing [Load].
