MLink

All Products Connectivity & Data MLink
Product Highlights
  • Plug & Play fast and easy setup
  • Integrated directly into the cable for seamless operation
  • Compact, small form factor for easy installation in tight spaces
  • Open-source code repository available for flexible third-party integration

Overview

Mlink transforms beadedstream Digital Temperature Cables (DTCs) into Modbus, SDI-12, or JSON nodes, enabling seamless integration with data loggers and SCADA systems. Built for flexibility, Mlink offers customizable settings configured at beadedstream to meet specific project requirements. To support integration with third-party loggers, we provide a publicly available code repository with example code, offering easy customization and programming options. Mlink is designed to deliver reliable performance across a range of environments and applications.

FAQs

We provide the necessary settings and documentation to help you program the data logger but the actual programming is typically done by the user or someone familiar with the third party logger. An MLink built into a DTC can be configured at beadedstream before shipping. Contact us if you are purchasing a DTC with MLink and know what configuration you’d like it shipped with. Examples below:

 

Modbus RS-485 Programming:

 

Protocol: Choose between Modbus-RTU, Modbus-ASCII, or JSON.
Baud Rate: Options are 9600, 1200, or 115200.
Format: Select from 8N1, 7E1, or 7E2.
Address: Any value between 1 and 247.

 

For additional programming support, we now offer a publicly available code repository with example code to help integrate other loggers with beadedstream cables. This code is open source. Submit a pull request if you want to contribute!

No, the M-Link is molded onto the temperature cable during manufacturing, so it cannot be retrofitted onto old cables. It’s essential to know where it needs to be placed on the lead cable for proper installation. An existing cable cannot be retrofitted with an MLink either.

One MLink unit is required per cable.
