Installation of SIM/UIM card:

Firstly power off the RTU, and press the out button of the SIM/UIM card outlet with a needle

object. Then the SIM/UIM card sheath will flick out at once. Put SIM/UIM card into the card

sheath (Pay attention to put the side which has metal point outside), and insert card sheath back to

the SIM/UIM card outlet.

Warning: Forbid to install SIM/UIM card when powered!

Installation of antenna:

Screw the SMA male pin of the antenna to the female SMA outlet of the RTU tightly.

Warning: The antenna must be screwed tightly, or the signal quality of antenna will be influenced!

2.4 Power

The power range of the RTU is DC 5~35V

Warning: When we use other power, we should make sure that the power can supply power

above 4W.

We recommend user to use the standard DC 12V/0.5A power adaptor.

2.5 Indicator Lights Introduction

The RTU provides three indicator lights: “Power”, “ACT”, “Online”.

Chapter 3 RTU Function Introduction

RTU is based on our ip modem which has realized data transparent transmission. It can collect

analog signal and digital signal. It also can output digital signal including 4 optocoupler isolated

outputs and 4 relay outputs. It has pulse counter. Main funcions as following:

1. Support dual data centers, one main and another backup, support multiple data centers

and it can support maximum 5 data centers, support multi-center multi-function(for

example: one data center works with MODBUS RTU protocol , another data center can

work with RTU extended protocol)

2. support multi online trigger ways, including SMS, ring and data. Support link

disconnection when timeout

3. Network is automatically connect,when device offline, it will automatically reconnect.

4. Support RS232/RS485 MODBUS RTU protocol, support TCP MODBUS RTU protocol

using TCP2COM software that converts TCP to virtual serial port.

5. Alarm function: Alarm information are reported through RTU extended protocol , SMS,

or both SMS and RTU extended protocol

6. Multiple configure methods.

7. Local and remote upgrade firmware.

8. Scheduled turn on and turn off power function make the device work in low-power mode

3.1 Multiple servers funticon

RTU support multi-center multi-function. Each center functions can be configured independently,

parameter settings please refer to appendix 4.1.4.6 Data Service Center Settings. Connection

protocol please refer to appendix 4.1.4.7 Work Mode.

3.2 MODBUS protocol

RTU support RS232/RS485 MODBUS RTU protocol. The principle of TCP MODBUS RTU

protocol is the same as RS232/RS485 MODBUS RTU protocol. TCP2COM softwave we

provided realize TCP to virtual serial port function(it can remotely transfer MODBUS RTU

protocol). The following introduces MODBUS RTU protocol, All of the following MODBUS data

are high byte first (big-endian mode).

3.2.1 MODBUS settings

Enable MODBUS function, related settings please refer to appendix 4.1.4.5 ModBus Setting, it

also need to configure the digital input, digital output, analog input and counter input

3.2.2 TCP2COM description

TCP2COM softwave realize TCP to virtual serial port function. The principle of TCP MODBUS

RTU protocol is the same as RS232/RS485 MODBUS RTU protocol. About using TCP2COM

softwave, please refer to appendix 5.1 TCP2COM Manual.

3.2.3 MODBUS digital IO input introduction

3.3 RTU extended protocol

RTU extended protocol has the following main functions:

1. Acquisition data(including analog input and digital input) are reported periodically.

2. Reporting mode can be selected. there are three reporting modes, including Network only,

SMS only and Main network ,SMS as backup(it uses SMS. when network connection fail)

3. When reporting acquisition data failure, acquisition data are saved to 2M byte SPI

nonvolatile flash which is saved forever even if the device powered off.

4. The data center can query acquisition data actively

5. It has counter function that the initial value of the counter can be configured, its realtime

value can be queried

6. It provede the transparent transmission tunnel between the data center and the terminal

devices which connected to the RTU RS232/485 port. This function works same as our

company’s ip modem.

7. It has alarm function and the alarm information can be reported periodically(alarm trigger

conditions can be configured independently).

8. It can be controlled to reboot from the remote side.

9. support remote configure the parameters

10. Local and remote upgrade the firmware.

Please refer to appendix 5.2 RTU center service.

3.4 Alarm function

Alarm informations can be reported through RTU extended protocol only, SMS only and both

SMS and RTU extended protocol. When alarm informations are reported through SMS, alarm

phone number and alarm content of each channel can be configured independently. detail

description please refer to appendix 5.2.7 Alarm information.

3.5 Multiply configure parameters

All the RTU parameters can be configured through RS232/RS485 、 SMS and RTU extended

protocol. Please refer to appendix chapter 4 configuration.

3.6 Remote upgrade firmware

RTU can remote upgrade firmware through TCP or UDP. First put new firmware (the version

should higher than the current software version) on RTU center software(its manual refer to 5.2

RTU center service) installation directory. then, configure upgraded parameters, these parameters

can be configured by SMS or RTU extended protocol. When RTU received the valid upgrade

parameters, it will upgrade the firmware automatically. Detail settings please refer to appendix

4.2.2.2 Overall setting by SMS or 5.10 Remote configure.

Chapter 4 Configuration

All the RTU settings can be configured through RS232/RS485、SMS and RTU extended protocol.

4.1 RS232/RS485 Configuration

Before configuration, It’s necessary to connect the RTU with the configure PC by the shipped

RS232 or RS232-485 cable as following.

4.1.1 Configuration introduction

There are two ways to configure the RTU:

Configuration software tool: All the settings are configured through the shipped software tool. It’s

necessary to have one PC to run this tool.

Extended AT command: All the settings are configured through AT command, so any device with

serial port can configure it. Before configuration with extended AT command, you should make

RTU enter configure state. The steps how to make RTU enter configure state, please refer to

appendix appendix.

The following describes how to configure RTU with the configure software tool. At the same time,

it gives out the corresponding AT command of each configuration item.

4.1.2 Run the configure tool

The “Serial Parameters” column shows the current serial port settings. To configure RTU,

please choose the correct serial port which connects to RTU, and the baud-rate is 115200 with no

parity, then open the serial port. If the button text is“Close”, it shows the serial port now has been

opened. If the text is “Open”, you should open the port first. When the port opened, the “Output

Info” column will display

“Port(COM1) Has Opened，Please Re-Power the RTU,

Waiting RTU Enter Configure State...”

After Re-power RTU, The configure tool will make it enter configure state. At the same time, the

software will load current settings from RTU and displays on the right configure columns. It’s

now ready to configure.
