Supported Equipment & Data Transfer Methods
Supported hardware types
Modern IoT solutions require a flexible approach to the selection of hardware components, especially when it comes to telemetry systems. Telemetry units, which act as a key link between physical devices and the Global Secure IoT Platform, differ in a number of critical parameters.
Important
The right choice of equipment ensures reliable data transmission, energy efficiency and compliance with the requirements of a specific infrastructure.
This section of the documentation describes the main criteria for classifying devices, as well as their technical features.
Classification of telemetry units
Power supply system
Telemetry units are adapted to work in a variety of conditions, which is reflected in their power supply options:
- Power supply devices: Powered by an alternating current network (220 V). Suitable for stationary objects with constant access to the power grid.
- Autonomous solutions: Long-life batteries (up to 5 years in low power consumption mode). Ideal for autonomous IoT devices without access to the power grid.
- Hybrid systems: A combination of solar panels, batteries and backup network power. Used in industrial facilities with a risk of power outages.
Key parameters:
- Supply voltage: 3.7 V (DC) / 100–240 V (AC).
- Power consumption in standby mode: ≤ 0.1 W.
- Battery life: Dependent on battery type and data transfer frequency (configurable via the platform).
External interface types
The units support the following interface types:
- RS-232/RS-485/UART-TTL: Physical layer standard for asynchronous interface.
- Optical port: For IrDA optical read heads.

Data transfer methods
The following methods of data transmission to the server are implemented:
- Request/response mode, via Type-T and Type-J protocols, for data exchange between the IoT device and the server.
- Direct data transfer initiated by the IoT device, via Type-J protocol.
Data transfer via Type-J protocol is possible both to a protected IoT platform, as well as to third-party OPC servers (for subsequent data transfer to SCADA-systems) and servers supporting SVD drivers.
