The SAA Field Power Unit (SAAFPU) comes equipped with a wireless cable replacement feature for use when a connection to a PC is inconvenient. Only the male 9-pin connector is required for use with an Android device to set up a Bluetooth connection. 


 

Step 1 - Configure the SAAFPU


Connect the ShapeArray (SAA) to the SAAFPU with either the 4-pin circular connector (Amphenol connector) or the 5-pin terminal block connector (Phoenix connector). 

Note: Only one ShapeArray can be connected to the SAAFPU at one time

Plug the wireless module with the male 9-pin connector into the female 9-pin connector of the SAAFPU.



Step 2 - Setup the Wireless Connection


To connect the SAAFPU wirelessly to an Android device, you must ensure that Bluetooth is enabled on the Android device and SAADroid is installed on it. Scan and pair for ‘FireFly-xxx’ and enter PIN ‘1234’. Open SAADroid on the Android device. 

Note: The communication range of the wireless pair is approximately 20 m.


For instructions on how to use SAADroid, please refer to the SAADroid manual.



Step 3 - Connect to the ShapeArray in SAADroid


In SAADroid, under the Setup tab, manually enter the ShapeArray serial number. Alternatively, you can click the Auto Find button to automatically locate the ShapeArray. Once the ShapeArray is located, click the Connect button. Once the green check-mark is visible beside the Connect button, SAADroid is connected live to the ShapeArray.
