Set transmission mode. There are TCP work mode and UDP work mode. Default is TCP
protocol.
Set up working Baud rate of serial port, scope is 110~230400BPS. Please set that baud
rate to the same as that of user side equipment. Otherwise, series port can't
communicate.
Set working data bits of serial port, and the value can be 7 and 8. Please set that data
bits to the same as that of user side equipment. Otherwise, series port can't
communicate
Set the parity of serial port, and the values can be NONE, ODD or EVEN. Please set that
parity to the same as that of user side equipment. Otherwise, series port can't
communicate
Set stop bits of serial port, and the values can be 1 or 2. Please set that stop bits to the
same as that of user side equipment. Otherwise, series port can't communicate.
Number DTU, supplying one way of differentiating DTU for center server. ID is fixed to
be 8 numbers. If it is not full of 8 numbers, please add 0 in front to make it full of 8
numbers.
Set mobile number which uses SIM card, and it is fixed to be 11 numbers. This
parameter cannot change SIM card mobile number, but a kind of way for center server to
differentiate connected devices
Default is 200ms.
Data that DTU receive packet rules as follows:
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 is set too small; it can result one data packet to be separated into
more data packets. If set is too large, it can result in two or more data packets to be
packed into one data packet and send to center server together. If it adopts 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 DTU are 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 it is
connected to server successfully
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 time of keeping alive data is sent periodically to maintain link. Unit is second.
Default is 60s. Interval of keeping alive time can't be set too small, if so, it will cause flow
