KB3061 Application Guide

7.1 Operation Steps:

(1)

Plug in SIM card;

(2)

Connect the antenna;

(3)

Set DTU Parameters;

Connect KB3061 to PC COM port via Development board or conversion circuit

Run the configuration software, choose and open the COM port that DTU connected;

Connect with the Power. KB3061 DTU Setting Software will list the menu of configuration. You can choose different menu to set different parameters, such as server IP, port, baud rate and so on. (Baud rate and Verify must be same with

深圳市金博通科技有限公司

Shenzhen Kingbird network technology CO.,LTD KB3061 CDMA DTU the device), then save the parameters and reset DTU.

(4)

Connect DTU with the device

Connect DTU with the device according to the interface define of DTU.

(5)

Star the control center software or the SCADA software to collect the remote device’s data.

7.2 User utility software R&D and Server planning

Users need planning on R&D software which in CDMA application, user can choose fixed IP servers or dynamic domain mode. Based on dynamic DNS is unstable, User is not advised to adopt this way. Here is the explain for the planning on software R&D based on fixed IP servers

Fixed IP server user can rent or hosting ISP Internet service provider, or can apply special line to our server.

Generally speaking, user's monitoring software can divide into two modes:

One is the user monitoring software and Data center software (Data center) integration. Namely the user monitoring software is installed on the Server, and its working mode as Server, it communicate with and manage every scene DTU directly, the advantage of this way is communication directly, no data transfer,

Disadvantage is that the flexibility for application is not strong, server must be in the user's master-control room (special line). So that users just can monitor and data collect in that server only.

Another one is the user monitoring software and Data Center software (Data

Center) separation, Data Center dedicated to Data transfer and each machine

DTU’s management, monitoring software only in charge of the customer's business logic processing, it communicate with Data Center software through network, and it with Data Center software is C/S architecture, the monitoring software working mode as Client, and Data center as Server. The advantage of this way is very flexible application, user no need special line, only need place the server in ISP service provider, and install Data center software into server. User can manage it only by user’s monitoring software, and when monitoring software install into a computer which connect with internet, it can achieve communication even in company or on business trip outside. The disadvantage of this mode is data need to transfer, monitoring software is not communicate with DTU directly, But communicate with data center software first, and then forward data to scene DTU.

Users can plan the whole CDMA application system according to user’s request.

Normally, users are suggested using the second modem, our company's server and server software is available to offer a lot of support when user debugging and trial in the early time. If users develop software completely, Our company can offer SDK or

Demo program when user monitoring software work as the server (when user monitoring software and data center software is integration) or Client (when user

深圳市金博通科技有限公司

Shenzhen Kingbird network technology CO.,LTD KB3061 CDMA DTU monitoring software and data center software is separation).

8. “Plug and play” of KB3061

Normally, users monitoring software based on serial communication mode before user use CDMA, if user want to use CDMA system, user is advised to change the communication mode to network communication mode, meanwhile, Put the protocol of CDMA DTU in monitoring software (Invoke SDK from DTU manufacturers) and building server and so on many developments and applications.

My company recommends "plug and play" solutions, user doesn't need to change its monitoring software, when users get our product, through my company's some software support, it can achieve remote CDMA communication through the monitoring software base on COM port communication modem. User can build a large SCADA system with our products and software in 10 minutes. In early time user debugging and try our products, user can use our server. If the bulk application is still need to adopt our company server, also can lease my company server.

Our company products "plug and play" solution requires our server software

(Center Data) to support, the following various network scheme adopts our company's server software (installed in users server or our company server).

8.1 KB3061 work with KB2000

KB3061 CDMA DTU can be used with KB2000-A (our product). If your software is based on serial COM, and device is COM port too (RS232 or RS485), then you can chose this Plan. This network is plug and play way. It need not any development of software and hardware User need to hire our company’s server. It can peer to peer and center to multi-point. This type network is very suit for the situation that device and the PC software are based on the COM port communication, and they need remote communication.

KB3061 connected with device as slave station. This way is called plug and play

(foolish application), no need to develop any software. User can use own server, or ours. Not only peer to peer, but also center to multi-point. This type network is very suit for the situation that main controlled room has no condition to surf the internet or outdoor, but need remote data communication.
