Hi,
yoe there is command to change sensors ID. There is two possibilities how to change this ID:
1. If you a re using the zstarlib.dll library, the situation is easiest - It must be called (when sesor is connected) theSensor.IndexSet(newIndex) method.
2. If you are communicated directly over serial/USB protocol - It must be sends command 'F'and new index to active sensor.
Have a nice day
