KB3050 GPRS DTU

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, ASCⅡ, UCS2.
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℃.

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.
