Additional Serial Port; Performance Testing; Current Testing - Fibocom G600 User Manual

reference and function when the G600 is running. The interface will be simulated to UART through
SPI, and then transferred to a serial port through RS-232 Transceiver SP3238EEA.
Meanwhile there are LSINT/LSCS LED indicator on development board that will indicate the
work state of SPI transfer serial port.

4.9 Additional Serial Port

There is a serial port simulated by G600 I2C interface on development board to satisfy some
special usage. The method of transfer is similar to Data logger, and the chips are same.
If you need use I2C interface, you can educe from JT2 directly.
There are three LSCL/LSDA/LIINT LED indicator on development board to direct the work state
of I2C transfer serial port.

5 Performance testing

5.1 Current testing

The current of G600 modules is an important item.
The development board is design with less current consumption. So It can be test with G600
module incorporable. The current consumption reflected the G600 current consumption exactly . We
commend following project.
Use the direct power supply
