The Peripheral Circuit Of Power Supplies; Main Interface - Fibocom G600 User Manual

The Peripheral Circuit of Power Supplies

There is a LDO chip that produces 3.3V voltage on development board to satisfy the need of
other IC, LED or others circuit.
Important:
And the tested current will be the current consumed by module only.

4.2 Main Interface

Main RS232 interface and USB interface will use a same UART interface of G600 module. They
have same function and command. Six LED indicators（LRI/LDCD/LDSR/ DTR/LRTS/LCTS）will
exactly indicate the logic level of each pin in UART interface of G600 module.
The default value of main communication interface: adapt to baud rate -8-N-1-NONE.
PC and other DTE equipments will fully satisfy all functions of G600 module through
communication interface and AT command.
Important:
