4. Hardware Instruction
The front view of ZLAN8100 DTU is shown as FIG. 1.
Installation instructions:
1) Antenna installation, the device antenna interface adopts 50Ω/SMA (female), the
external antenna must use the antenna suitable for GPRS work band, if use other
antenna that not match, it may influence or even damage the DTU. It can be
equipped with a short antenna or an extended antenna.
2) SIM card installation, this device use mobile GPRS network, need to purchase a
SIM card from the mobile operator, when installing the SIM card there should
ensure that device is not power on, this device use the drawer-type SIM cassette,

when open, need to push the yellow button inward, and then pull out card sets, after
installed the SIM card, push the card sets in.
Penal light:
1) ACT: blue, the ACT light on indicates that data is being transmitted between GPRS
network and serial port, when there is no data communication, the ACT light is not
bright.
2) LINK: 64ms on/ 3000ms off, indicating that GPRS is normally registered, and other
scintillation frequency indicates GPRS registration abnormality.
3) POWER: red indicates that ZLAN8100 has already been power on.
4) GPRS light: GPRS operating status indicator.

5. Work Station
1) The work mode of ZLAN8100 is mainly divided into normal working mode and user
configuration mode. Before normal use of this DTU, users should configure

Shanghai ZLAN Information Technology Co., Ltd Tel: [phone] http://www.zlmcu.com
8
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.
6.1Normal 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.

2) Data to Trigger Online
DTU device will automatically connect to the data center after the device is
switched on, and then the DTU will automatically get offline if there is no data
from the serial port or data center in a certain time. Until there is data from the
serial port, it will be triggered online, and the data will be reported. After that, if
the data is not available for a period of time, it will be automatically removed.
6.2User Configuration Mode
In this mode, the basic working parameters of the device can be obtained, and the
user can modify the work parameters according to the locale. The specific steps are
as follows
1) Enter Configuration Mode
i. Open the software first, as shown in FIG. 4 configuration tool.
Figure 4 Configuration Tool

ii. Select the serial number and other parameters unchanged.
iii. Charge the device and wait for the Active light on.
iv. When the Active light is on, please open the serial port in 2 seconds
(click the "open" button of the software)
v. Wait a while, the basic information of the device will be checked out.
vi. This process lasts for up to 30 seconds, and the timeout cannot enter
configuration mode.
The basic information of the device is shown in FIG. 5, and the more commonly
used is the TCP/IP parameter, which is listed here in the main interface. The
information box section is the data returned by the AT command.
Figure 5 Device Information
2) Obtain Device Parameters
When the device enters the configuration mode, we can get his work parameters
and click the "get parameter" button. The software will automatically perform this

function after the search is completed, so no extra access is needed.
3) Landing Device
If you want to set the parameters, you must log in, and the default password is
666666. If you just get the parameters, you don't need to log in. Click the LOGIN
button to LOGIN the device, and in the information box section, you will see “+
LOGIN: OK”, means the LOGIN is successful, the LOGIN status will change,
otherwise LOGIN failed, please confirm whether the password is correct or not.
4) Setting Parameters
Modify the parameters you need to change (if the parameters need to be valid)
and click "Set Param.". After setting the parameters, there is no obvious prompt
information. If the information of the parameter box is consistent with the set
information, the modification is successful, and the information box will also have
relevant information.
5) Advanced Parameters
Advanced parameters are generally configured by default. Specific instructions
refer to parameters explanation.

7. Usage
Figure 7 Network Structure
The basic usage method is given here, mainly the parameter configuration of 8100DTU.
First is the Server settings, it needs to have a public network IP address. The software
on the server opens 4196 (any) listening port and waits for the client's connection
request. If the server is an Intranet connected to a router, a port mapping is required to
establish a connection. Here we assume that the user server has a public network IP
address.
Next is the 8100 DTU Settings, as shown in FIG. 8 sets the destination address, using
the configuration tool to fill the “Dest. IP/Name” with Server IP, and fill the “Dest.” with
port, put the device on power after parameters setting. It is important to note that these
parameters need to set up in advance because the 8100 currently supports only the
serial port configuration.
