-The modem may be configured to start automatically or manually, an SMD transfer has been provided to ON/OFF manually.
-Flap type SIM Socket is provided on pinnacle side of the board to ease the get right of entry to and the SIM Pins are blanketed from antistatic excessive voltages the usage of onboard Transient Suppressors.
-All audio interface connections are to be had on Header pins after necessary clear out circuits.
-The Modem is populated with Edge mountable SMA Connector for GSM Antenna and UFL connector for optional external High advantage GSM Antennas.
-Option has supplied to attach USB interface for updating the module Firmware if wished.
-3LED's are furnished to indicate the modem reputation.
-The baud fee is configurable from 9600-115200 via AT command.
-The GSM/GPRS Modem is having inner TCP/IP stack to permit you to connect with net via GPRS.
-It is suitable for SMS, Voice as well as DATA switch application in M2M interface.
The Modem is manufactured with Automatic Pick and vicinity gadget with high exceptional fashionable. The onboard Low dropout 2A Power supply lets in you to attach huge range unregulated electricity deliver (5V-12V). Using this modem, you can make audio calls, SMS, Read SMS, attend the incoming calls and net and many others through simple AT commands.
