F2114 Low Power Consumption GPRS IP MODEM (GPRS DTU)
F2114 GPRS IP MODEM is a kind of cellular terminal device that provides data transfer function by public GPRS network.
|
Low consumption design Support multi-sleep and trigger modes to save power consumption
|
Supply 5 I/O Compatible 2 pulse wave output channels,2 analog inputs and one pulse input counter
|
Multiple online/offline trigger modes Support several online trigger ways,including SMS,ring and data,support link disconnection when timeout
|
Suppot SMS backup Modem will switch to SMS state to send the data by SMS when GPRS/3G Internet is down or data center is off. Modem can switch back to communication state from SMS state when GPRS/3G Internet or data center recovers.
|
Support scheduled power on / power off mode The power consumption is less than 1mA in scheduled power off mode
|
Support APN/ VPDN network Improve the security of data transmission
