Note:

To use this feature, we strongly suggest to get special GPRS service from your network

operator :

a. Network will assign a true public IP address to M100 2G upon GPRS activations, and

b. that GPRS connection allows incoming access from public Internet to Maestro

This feature lets Maestro 100 2G to login to certain Dynamic DNS service providers, to update the hostname with M100

2G current IP address. So user can access M100 2G with pre-registered hostname. User can use this function together

with “TCP Terminal” (see Chapter 8 ) and can use Telnet to access M100 2G and send AT command over Internet.
