         3 . The diagnostic device of  claim 1 , wherein the first pinout map includes a plurality of portions, each portion identifying a different electrode and the respective one of the plurality of channels at which the signal generated by the electrode is received. 
     
     
         4 . The diagnostic device of  claim 1 , wherein the first pinout map includes a plurality of portions, each portion identifying a different electrode and respective contact which the electrode is coupled to. 
     
     
         5 . The diagnostic device of  claim 1 , wherein the diagnostic device is further configured to store the first pinout map in the memory that is integrated into the diagnostic device. 
     
     
         6 . The diagnostic device of  claim 1 , wherein:
 the deployment location is inside a body of a patient, and   each signal change is caused in response to a different electrode coming in contact with a tissue of the patient.   
     
     
         7 . The diagnostic device of  claim 6 , wherein the diagnostic device is further configured to output an indication of a condition of the patient based on the pinout map. 
     
     
         8 . The diagnostic device of  claim 1 , wherein each of the plurality of electrodes is configured to deliver a respective one of the detected plurality of the signal changes to the respective one of the plurality of channels. 
     
     
         9 . The diagnostic device of  claim 1 , wherein the transition from the first state to a second state includes:
 obtaining a second pinout map indicating the interface standard supported by the diagnostic device.   
     
     
         10 . A method for configuring a catheter, comprising:
 inserting a shaft of the catheter in a deployment location, the shaft including a plurality of electrodes disposed in a linear order on the shaft;   detecting a plurality of signal changes that occur during the insertion of the catheter in the deployment location, each signal change being a change in a value of a different signal that is received at a respective one of a plurality of channels from one of the electrodes; and   generating a pinout map associating each of the electrodes with a different one of the plurality of channels based on a temporal order in which the signal changes are detected.   
     
     
         11 . The method of  claim 10 , further comprising receiving an indication of the order in which the electrodes are arranged on the shaft, wherein the pinout map is generated further based on the order in which the electrodes are arranged on the shaft. 
     
     
         12 . The method of  claim 10 , wherein the pinout map includes a plurality of portions, each portion identifying a different electrode and the respective one of the plurality of channels at which the signal generated by the electrode is received. 
     
     
         13 . The method of  claim 10 , wherein the pinout map includes a plurality of portions, each portion identifying a different electrode and respective contact which the electrode is coupled to. 
     
     
         14 . The method of  claim 10 , further comprising storing the pinout map in a memory that is integrated into the catheter. 
     
     
         15 . The method of  claim 10 , wherein:
