MDR2184 RTU_Summarize

MDR2184 is a wireless measurement and control terminal (RTU) that uses GPRS/4G wireless network remotely acquisition analog and digital signal and control relay.

MDR2184 is an all-in-one cost-effective solution with built-in industrial-grade GPRS/4G module and embedded processor, which realizes field data acquisition /wireless data transmission /remote control.

MDR2184 RTU_ Product Features

• 4-Channel digital and 8-channel analog signal input, 4 relay output.
• Built-in industrial-grade embedded CPU to operate the complex network protocols, support PPP, TCP, UDP, DNS and other protocols, provide transparent transmission channels for user data, compatible with RTU features.
• Has stable performance and built-in watchdog to ensure long-term reliable operation in harsh outdoor environment.
• Supports fixed IP or dynamic IP and dynamic domain name resolution of the data center. 
• The data interface adopts RS485 communication interface. The baud rate can be selected from 1200bps to 115200bps, and the start bit, stop bit and parity can be selected.
• Support graphical parameter configuration, built-in EEPROM, long-term storage of user-configured parameters. 
• Support APN data private network. The data center supports SDK programming and standard socket programming.
• Use the anti-interference design for application in harsh electromagnetic environment.
• Wide operating temperature ranges. It can work between -25°C with +70°C.
• Adopt Modbus RTU protocol, which is more compatible and easy to use.
• Automatically judge whether the collected switch signal/analog signal exceeds the threshold, and automatically sends alarm information.
• Pre-warning Period and warning value can be flexibly set.
• Support IoT Cloud.
• Support virtual serial port, support accesses multiple configuration applications.

Have self-owned development technique

Support script programming

MDR2184 supports script programming, and users can customize scripts. It does not require an additional controller or data center to issue instructions and directly connect to the instruments, actively collect data, and upload it to the data center.

Data of up to 20 instruments can be collected, greatly reducing hardware costs. The reporting logic of DI (Switch signal) and the control logic of DO (relay output) can be defined in the script.

User Guide

Before using the MDR2184 RTU, the user should configure the working parameters of it appropriately. The operation processes as following:

1,When the RTU is powered on, the SYS indicator flashes, indicating that the RTU has started to work.

2,Connect the RS232 serial port cable.

3,Start the RTU/RTU Config Tool (when using the configuration software for the first time, please read the operating instructions of the configuration software).
