NOTE:

When the UART signals are used as the communication port between the host and the

modem:

• The DTR pin must be connected to enter LE940B6 power saving mode.

• The RI pin must be connected to wake up the host when a call is coming while the host

is in Sleep mode.

• The RTS must be connected to GND (on the module side) if flow control is not used.

If the UART port is not used, all UART signals can be left disconnected.

NOTE:

Unless otherwise specified, RESERVED pins must be left unconnected (floating).

The only exceptions are in the following Section: 3.2 LE940B6 Signals That Must Be Connected.
