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), 8303-7 (Support Mobile and Unicom 3G/4G), 8303N (Support P2P). The function of Modbus TCP and P2P can add to models 8303 or 8303-7 such as ZLAN8343N-7.

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-7 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.

ZLAN8303-7 don't have P2P function, only ZLAN8303N-7 have P2P function.

Normal 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.

Application

-Finance, GPRS, etc.

Features

1)       The supporting 3G/4G network

a)       8303/8343/8303N/8343N: support EVDO/CDMA2000, Telecom 3G network

b)       8303-7/8343-7/8303N-7/8343N-7: support 7 modes, TD-LTE/ FDD-LTE/ WCDMA/ TD-SCDMA/ EVDO/CDMA2000/GSM, Unicom 4G/3G/2G, Mobile 4G/3G/2G and Telecom 2G/3G/4G network

2)       Provide an Ethernet port, can be used as 3G router. Can be used as Ethernet DTU to save traffic when on the cable network, same as serial port server.

3)       Support P2P connection, no need fixed IP and server, convenient to communicate and connect.

4)       Support Modbus gateway, as Modbus TCP converting to Modbus RTU.

5)       Support multiple hosts monitoring, no interference between each other.

6)       SIM card installation in drawer type without disassembly.

7)       8303 can be controlled in dormancy via serial port to operate in low power.
