1.1 Brief Introduction
Based on years of experience of providing mobile data’s industrial application
solutions and service operator’s network configurations, BeiJing GemoTech has
designed RemoDAQ-8554A GPRS DTU which works at an advanced platform with
individualized feature options to meet different requirements. Along with mobile
communication technology’s development, the GPRS data networks have covered
all country; this brings a bright future for industrial applications.
Figure1.1 RemoDAQ-8554A GPRS DTU
GPRS network theoretically can provide a maximum bandwidth 171.2Kbps,
actually, it works at 40~100Kbps bandwidth (it depends on service provider’s
operation policy). As we know, GPRS is packet based network which provides
TCP/IP communication channel.
RemoDAQ-8554A GPRS DTU provides industrial end-user a virtual private data
network of high speed, always online, and transparent data transmission. It can
be widely used at area power system, industrial supervision, automatic traffic
control, weather station, environment protection, pipe supervision, finance and
securities, etc.

1.3 Installation
RemoDAQ-8554A GPRS DTU should be installed and configured properly before
putting it in service.
Attention:
Do not install RemoDAQ-8554A GPRS DTU or connect/disconnect its cable when it
is power on.
1.3.1 SIM Card Installation
Open top SIM protection cover, and then insert SIM from left-top side. SIM card
conductors should face downside and the gap face to outside. The SIM card also
need to be inserted properly and then cove back the SIM protection cover in order
to prevent the SIM card from dropping out during shipping. Slide the SIM card by
your finger to take out the SIM card.
Attention:
RemoDAQ-8554A GPRS DTU will not work and display “No SIM card, Please insert
SIM!” if you do not insert the SIM card to the end position. In order to prevent this
problem, please put back the SIM cover after you insert the SIM card, and screw
it tight.
1.3.2 User Data and Power Cable Installation
RemoDAQ-8554A GPRS DTU signals and power supply is connected by industrial
class pluggable terminals, 3.5mm, 12Pin, and 14~24AWG outlet cable is
recommended. Each line definition refers to the following diagrams and tables.
Also, you can find outlet cable definition table at top of RemoDAQ-8554A GPRS
DTU cover.
As shown in the following diagrams and tables, peel off the cable end about 7mm
and connect each terminal and cable (14~24AWG cable recommended). Make
sure that you have connected the terminals without any mistake.
Attention:
1. The power cable should be connected correctly. We suggest double check
before switch it on. Wrong connections may destroy the equipment.
2. Power terminals: Pin 11 and Pin 12; Here: Pin 11 is “GND”, Pin 12 is power
input “Vin+” (+12~+30VDC).

1.3.3 Grounding
To ensure a safe, stable and reliable RemoDAQ-8554A GPRS DTU operation, DTU
cabinet should be grounded properly. Connect the RemoDAQ-8554A GPRS DTU
cabinet to site ground wire at the ground point
1.3.4 Power Supply
RemoDAQ-8554A GPRS DTU is designed with advanced power management
technologies; it can operate standalone. The DC power is supplied via pluggable
terminal Pin 11 (GND) and Pin 12 (Vin).
About Power Supply
When RemoDAQ-8554A GPRS DTU communicates with base station, surge
current will exceed normal current. Therefore, margins 5 times over normal
current may be required for external power supply.
Normally, RemoDAQ-8554A GPRS DTU input power supply is +12~+30VDC, in
