1. Summary
ZLAN8303 is 3G/4G network solutions launched by Shanghai ZLAN after ZLAN8100. The
serials contain 4 sub-models: 8303 (support Telecom 3G), 8343 (Support Modbus TCP
Gateway), 8303-5 (Support Mobile and Unicom 3G/4G), 8303N (Support P2P). The
function of Modbus TCP and P2P can add to models 8303 or 8303-5 such as
ZLAN8343N-5.
Figure 1 ZLAN8303 Appearance
8303 has RS232/485 interface, can send the data collected by RS232/485 to the cloud
server. Combined with ZLAN P2P technology, the users can collect data anytime and
anywhere without building server, the collecting method can also be a virtual serial port. If
be 8343N, can convert Modbus TCP protocol to Modbus RTU, the users use Modbus TCP
to collect data of RTU devices on the computer. ZLAN8343N and ZLAN8343N-5 are the
most functional serial server separately applied to P2P Modbus Gateway of Telecom and
Mobile/Unicom, suitable for PLC monitoring and field data collection very well.
8303 also has the Ethernet port, can use it to communication in the places with Ethernet,

users can save the 3G/4G traffic. In addition 8303 can be used as 3G/4G router to achieve
Ethernet port converting to 3G/4G.
Applications:
PLC remote monitor
Industrial remote control/sensing/measurement
Public Utilities
Meteorological Data Acquisition
Three-Proofing & Hydrology Monitor
Finance, GPRS, etc.
The following is the application of each sub-model respectively. Please refer to section 5
below for model selection.
1.1Normal 3G/4G DTU
The normal 3G/4G DTU can be as TCP Server connected by other network devices,
since the 8303 IP is not fixed when under 3G/4G mode, usually it isn’t as TCP Server,
but mostly as TCP Client to connect an fixed IP (or domain name) Server, and send its
collecting data. The software on Server ask data through polling style. The RS485/232
of 8303 can connect with serial device and PLC needed collected, sending polling
command to PLC, and upload the returned data to server. Shown as Figure 2.
Figure 2 Normal 3G/4G DTU Mode
In this way the purpose of the 8303 IP must be set to the server IP, that is to say the

user must lease a server with a public network IP. However, for some application users
may not have a public network server, because the user dial-up through the router, then
the router must be set on the "port mapping" and "dynamic domain name" to send 8303
data to the server. "Port mapping" and "dynamic domain name" have the following
problems:
1) Some routers are standard telecom, cannot log in so cannot do some settings.
2) "Port mapping" for the average user may be too specialized, set up trouble.
3) "Dynamic domain name" free program may exist stability, real-time problems.
Of course, for the public network IP server users, ordinary ZLAN8303 is also very
convenient to use. The following lists the differences between ZLAN8303 and
ZLAN8303-5.
In this way, the Destination IP of 8303 must be set to the server's IP, which means that
the user must rent a server with a public network IP. But for some applications the user
may not have a public server, because the user access Internet through a router dial-up,
at this time user must set “Port Mapping "and" Dynamic Domain Name "on the router so
that can send 8303 data to the server. There are some problems with "port mapping"
and " Dynamic Domain Name":
1) Some routers are Telecom standard matched, unable to log in so that some
Settings cannot be done.
2) "Port Mapping" may be too specialized for regular users as setting up with trouble.
3) The free scheme of "Dynamic Domain Name" may have stability and real-time
problems.
Of course, for users with public network IP servers, it is also convenient to use the
normal ZLAN8303. The differences between ZLAN8303 and zlan8303-5 are listed
below.

CDMA2000, Telecom 3G network. If you use a Telecom 4G card, you
can also communicate, but in 3G mode. 3G speed is enough for data
monitoring. So you don't have to deal with 3G CARDS.

ZLAN8303-5
Support 5 operating modes, support Mobile, Unicom card, Telecom 4G
card (but does not support telecom 3G/2G card).
1.2Multi-host and Modbus Gateway
The model with this function is ZLAN8343 or zlan8343-5. These two models have the
following two functions:
1) Modbus Gateway can be configured. As long as set the “Device/Advanced
Parameter/Transformation Protocol” to "Modbus TCP to RTU", it is switched to
Modbus Gateway mode. The upper computer can be queried with Modbus TCP,
while PLC can use RTU instructions. The Modbus of 8343 is storage Modbus
Gateway, and the polling is more real-time.
2) Multiple hosts. When set to Modbus Gateway, multiple host queries can be made,
and 8303 will answer separately to realize multi-host query. In the non-Modbus
Gateway mode, for the 8343 model, you just check the "multi-host" support in more
advanced options it can also implement the multi-host queries.
ZLAN-multi-host technology is a technology developed for multi-host monitoring a
device at the same time. In the ordinary serial device server or DTU, when there isA, B
two monitoring computer, A and B can send data to the device, but data the device
received from the serial port will be sent to theAand B at the same time. In other words,
when A and the device communicate, B will receive unwanted data, which will interfere
B's communication. Many software protocols will not be able to adapt to this situation
and may not work.
The ZLAN multi-host technology can can achieve the communication scheduling
betweenAand B computers.WhenAcommunicates with the device, the response data
of the device is only sent to A; When B needs to communicate, you can quickly switch
to B. ZLAN8343 will enable multiple computers to monitor the same device
simultaneously.
1.3P2P 3G/4G Serial Device Server
The model with this function is ZLAN8303N or ZLAN8303N-5. This model integrates

ZLAN's P2P technology, which can solve the inconvenience of "Port Mapping" and
"Dynamic Domain Name" in general 3G/4G DTU.
Figure 3 3G/4G DTU Mode of P2P
As shown in FIG. 3, compared with FIG. 2, (a) we increase the ZLAN P2P server, (b)
the user computer replaces the monitoring server. Instead of using the server for
monitoring, users can monitor their laptops whenever and wherever they are.
At the beginning of the communication, the P2P software on the user's
computer---ZLVircom, communicated with the ZLAN P2P server. At the same time,
8303 can also communicate with ZLAN P2P server, which can establish direct
communication between 8303 and ZLVircom (without the P2P server forwarding) after
the negotiation is done. The software on the user's computer can communicate via a
virtual serial port provided by ZLVircom or a TCP mock port.
When used, the user only needs to enter the serial number of 8303 that needs to be
monitored in ZLVircom software to establish the P2P connection. The P2P approach
allows users to get rid of the "Port Mapping", "Dynamic Domain Name" and the server
of a public network IP, which can easily and conveniently do monitoring anytime and
anywhere.
The combination of P2P technology and 3G/4G wireless technology has implemented
an innovative monitoring method, which has the following characteristics:
1) Easy to use, users only need to add the serial number of 8303 so can go to

operate, no need any professional operation such as Port Mapping.
2) No additional cost, users no need to lease public server.
3) Support virtual serial port, no need to modify client PLC software, like local serial
communication.
4) As no need to transfer through server, but direct P2P communication, shorten data
communication time, improve the communication real-time, reduce the load of
center server.
5) Support communication type of encryption and user name authentication to ensure
the security of communication.
