9 / 28
1.
1)
Within operation temperature range, the module is 3GPP compliant.
2.
2)
Within extended temperature range, the module remains the ability to establish and maintain
functions such as SMS and data transmission, without any unrecoverable malfunction. Radio
spectrum and radio network will not be influenced. While there may be several parameters, such as
P
out
reducing in value, exceeding the specified tolerances of 3GPP. When the temperature returns to
the normal operating temperature level, the module will comply with 3GPP specifications again.
3. The peak current of the GSM part of the module reaches 1.6A. When the GSM part works, power
should be supplied with a power adapter, of which power supply capacity should be no less than 2A.
4. “*” means under development.
USB Interfaces
Support two UART ports
Main port (USB Serial Converter A):
Used for AT command communication and data transmission, baud
rates 2400bps, 4800bps, 9600bps (default), 14400bps, 19200bps,
28800bps, 33600bps, 38400bps and 57600bps are supported
