ZLAN8100 according to their own needs, and then the DTU can enter the normal
mode of work.
2) Normal Working Mode
After the initialization phase, DTU will enter the work mode of data transmission. In
this mode, the device's serial port will transparently receive and send the user's data.
Please refer to user interface configuration for user data control parameters.
3) User Configuration Mode
When the system starts initialization, you can enter the configuration mode after
receiving the specified command, and DTU can enter the user configuration mode.
At this time, the serial port of the device has been transferred to the configuration
status, can use ZLAN “ZLAN8100 Configuration Assistant” tool to configure. After
the configuration is completed, with power on the device can be in use. For
customers who need to develop their own configuration code, please refer to
<ZLAN8100 Configuration Instructions>.
6. Optional Work Station Instruction
The GPRS DTU device of ZLAN technology supports the following two working modes,
and users can set reasonable working mode in combination with actual communication
requirements. In general, the system needs real-time query and timely reporting using
real-time online working mode to ensure the validity of data. In the case that only there is
data so need to report, it can use work mode of data to trigger the online.
6.1 Normal Working Mode
1) Real-time Online
DTU device maintain effective data link connection with data center, it can do
real-time data communication between the two, the actual application can adopts
connection-oriented TCP method, and combined with a heartbeat packets to
maintain connection, also can use the non-connection-oriented UDP method
provided by this device, plus the heartbeat packets to maintain connections, as a
result of the UDP packet routing address jump degeneration is big, user can
narrow the heartbeat interval, to keep the data center can prompt reply.
