has been inserted. The col,our green is only used when the module has been inserted into the interface. The
led supplies information regarding the module via adifferent methods of flashing as follows:
• fast flashing, with frequency of about one second, indicates that a scan is being performed to search for
the related module to which to connect;
• slow flashing, a flashing of the light about every two seconds indicates that the modules are connected;
• fixed, lights up for two seconds, indicates an error has occurred and the module will reset itself;
• alternate flashing of both colours means that the module is in the process of being activated, which
normally takes about a second.
