 Module index
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 Modules are indexed based on their order in the hostname command. They are used to configure a specific module within a detector and are followed by a ':' in syntax.

 The slsDetectorPackage supports using several detectors on the same computer.

+Accessing individual modules
+----------------------------------
+
+Using the C++ like API you can access individual modules in a large detector
+by passing in the module index as an argument to the function.

+    
+    # Read the UDP destination port for all modules
+    >>> d.getDestinationUDPPort()

+From the more pythonic API there is no way to read from only one module but you can read 
+and then use list slicing to get the values for the modules you are interested in.
