 ## Description
 
-The Master-D1 is a digital acoustic position computing board. It calculates the position of any Locator relative to the position of the Receivers, as well as global position through use of the integrated GPS and IMU (compass). The board supports up to 7 independent D1 devices, 1 A1 device or 1 U1 device. It is accessed through a network interface. The Master-D1 is running its own webserver which exposes an API and a GUI. With its small physical footprint, the board is easily integrated into a topside housing.

 ## Benefits
 
-* Extremely small footprint enabling easy integration in other equipment.
+* Extremely small footprint enabling easy integration with other equipment.
 
 * Highly robust operation in areas with reflections (shallow water, around installations etc.)

 If Shutdown is left floating, the Modem is ON. If Shutdown is short to GND, the modem is OFF. 
 Shutdown line can be controlled by an external open-drain, open-collector or relay device.
 DO NOT apply voltage to Shutdown line.

 Verify Receiver signal strength in the diagnostic page on the web GUI by going to the diagnostic tab in the side panel on the left. This view will show the signal strength from all Receivers. It should look something like this:

 In the diagnostic plot you should see the signal from all 4 Receivers. The signals should be well above the noise floor.
 
 ## Interference
 
 Acoustic interference can be observed in the diagnostic plot. Echo sounders from your boat or nearby boats typically appears like burst noise.

 If it is coming from your boat, try to turn off the echo sounder to improve position accuracy.
 In case of interference from other acoustic sources, use the GUI to try other channels to avoid the interference.
