Status LED’s
The miniPCIe-CEFIRO cards provide four LED indications directly attached to the EHS6/8 module, as
the following table summarizes:
Each GPIO of the EHS6/8 module can be controlled by AT commands or an embedded Java application.
In addition, DL3 is connected to the LED Status signal of the module, which is automatically handled
by the EHS6/8 module and indicates its different operating modes, as shown in table below. The LED
mode configuration is set by the AT^SLED command.
The signal GPIO5/LED of the module is also connected to the LED_WWAN# signal in the 52-pin
application connector.
