1 Brief Introduction

Thanks for you to use our products!

1.1 Brief Introduction

KB3050 GPRS DTU (Data Terminal Unit) is wireless data transmitting terminal of

GPRS/SMS and embedded with High reliable ARM7 CPU.

Based on the public net, KB3050 GPRS DTU transmit widely, stably and reliably,
KB3050 GPRS DTU is widely used in unattended operation device, Remote AMR, remote
data acquisition, remote AMR, remote scheduling and so on. Due to this product is
designed for industry integrated, we adopt special designs in the temperature scope,
shaking, EMC and interface multiform and so on, to keep it good stability in the severe
atmosphere, ensure high quality for your device.

Aim at different scope user’s requirements to supply different define GPRS Terminal
unit, it needs taking industry characteristics for developing on hardware & software and
system integration. GPRS mobile net can supply TCP/IP connection; GPRS DTU can be
use for internet connection, data transmitting application and so on. KB3050 GPRS DTU
(Data Terminal Unit) is special GPRS wireless device that send the data from COM port
through GPRS mobile data network.

KB3050 GPRS DTU is used in electric power automatic system, industry monitoring,
traffic management, atmosphere, pro-environment, pipe network monitoring, finance,
securities departments and so on. Consider the networking request from different
application scope, achieve Virtual data private network in network structure. It is applicable
to small and medium data transmitting of the Center to multi-points, multi-points scatter.

8B1.2 Product Feature

 Various working mode: DTU (default), Modem, SMS Modem. DTU mode is GPRS

data transmission which can get the data from device’s COM port
(RS232/RS485/TTL) and transmit to the server in Internet. It also can receive SMS
Message when DTU mode (it needs to switch IO port to SMS when send message).
SMS Modem is SMS transmission mode, user can set to type A (with protocol) or
type B (transparent). When set to Modem, compatible standard AT command
(GSM07.05 and 07.07). user can write AT command software to realize the
function user need.

 DTU and SMS Modem can switch through User configuration software and also

can change the working modem through IO port. Set the parameter of Modem
mode must after it is power-on.

 SMS Modem feature:

 Various networking ways: Under SMS Modem, the device with protocol (A) can

network with the device without protocol (B), the device with protocol (A) also can
network with the device with protocol (A).

 Under SMS Modem, KB3050 can receive and send the MAX data 1024 bytes a

time.

 Under SMS Modem, support Sending and Receiving Data form: hex, ASC , UCS2. Ⅱ

User is advised to set this parameter through our configuration software before use
it.

 Various networking ways: KB3050 can work with NET Converter KB2000 and

KB3050 (it is convenient to use GPRS without internet). This can achieve
networking of peer to peer, center to multi-points.

 Plug and play: when work with KB2000 or KB3050 of our product, no need to

develop any software and hardware, can build large SCADA system.

 Automatical IP register mechanism, can achieve various server modes, build

complete super large SCADA system.

 Remote sleep and awake: User can use appointed cell phone number to dial or

send message can sleep or awake DTU, it is convenient for user to save a lot of
GPRS Flow Fee when no need to use DTU.

 Remote modify DTU parameters: Support that SMS and data service center modify

DTU parameters.

 IO switching value function: Two channels input, two channels IO output. Remote

control and reading. Alarm status threshold, automatic alarm signal report function.

 Strong communication backup function: Support automatic switching between main

server and backup server, support TCP and UDP automatic switchover (now don’t
have TCP and UDP automatic switching function). It will connect to backup server
when main server has problem, and will take UDP to communication once TCP off
line.

 Strong server software support, application for many years, strong function.

 Support special APN, data center support fixed IP and DDNS.

 Working temperature range: -40℃-80℃, communication is not effected at -40℃.

10Pin.

3.5 Inspect network situation

Connect cable and antenna, insert into effective SIM card, power-on KB3050, the
power light of MODEM will flash, after 10 seconds later, the power light will always light, it
means KB3050 into a normal work condition and connect with network successfully.

Note:

Before power-on, must confirm KB3050 connect with cable correct;

Before power-on, make sure to connect the antenna, to avoid RF impedance mismatch
and damage module.

4 Working mode switch

KB3050 default value is DTU modem, the way of switch working mode as below:

1. Switch to SMS modem: it has two ways, when under DTU mode, can change the
device type to SMS modem when set DTU parameters. Another way is that switch the IO
port (put the Pin 10 to low) to change the working mode.

2. Switch to Modem mode: when run the product, put AT command: AT+QLOCPU=0
to change working mode to Modem.

3. Switch to DTU mode: it has two ways, when under SMS Modem, can switch the IO
port (put the Pin 10 to high) to change the working mode to DTU. Another way is under
Modem, put AT command: AT+QLOCPU=1 to change working mode to DTU when run the
product.
