11 numbers. This parameter cannot change SIM card mobile number, but a kind
of way for center server to differentiate connected devices.
 Frame interval： Default is 200ms.
Data that DTU receive packet rules as following:
1. When serial port receives data whose length is more than appointed
buffer 2048 bytes, DTU will packet the receiving data and send to center
server.
2. Within the configured "frame interval" time, DTU equipment hasn't received
any serial port data, DTU will packet the received data and send to center server.
"Frame interval" time set too small, it can result one data packet to be
separated into more data packets. If set too large, it can result two or more data
packet to be packed into one data packet and send to center server together. If
adopt our default value, one packet will be separated into more or more packets or
it will be packed into one. If customer can't calculate the suitable value, please
contact our technical support engineer.
 Times of reconnection：Times of DTU to connect with center server, and the
default is 3. If trial times are more than configured "times of reconnection",
gateway will automatically power down and after a moment power on again,
and dail-up, reconnecting center server till connect server successfully.
 Interval of reconnection：Interval time of wireless gateway to reconnect with
center server, the unit is second. When the connection with center server fails, if
reconnect time is less than configured times, it will reconnect center server
within the appointed time.
 Interval of keeping alive：Interval time of keeping alive data sent periodically
to maintain link. Unit is second. Default is 60s. Interval of keeping alive time
can't set too small, if so, it will cause flow increasing. It also can't be too large,
if so, device can be detected after long time offline. Suggested value is
10S<X<120S
 Self-registered packet： When DTU establish connection with center server,
DTU will send registration information to center; if registration packet needs
specific definition, please install the specific definition here
 Keep alive packet define： After DTU connect with wireless network, if there is
no data transmission within a certain time, wireless network will disconnect
with DTU automatically. In order to keep DTU connection with wireless
