FAQ
You can reach our technical support in three ways:
- Fill out the support form on this page
- Email us at: info@rossma.ru
- Call us during business hours (Mon–Fri, 9:00–18:00 MSK)
We respond within 24 hours on business days.
The standard warranty for all ROSSMA equipment is 36 months from the delivery date. During the warranty period, we fix manufacturing defects and replace faulty components free of charge.
For extended warranty options, contact your account manager or check our partner programs.
To update firmware:
- Download the latest firmware from the «Downloads» section on this page
- Connect your device via USB or use OTA updates through a LoRaWAN server
- Run the update utility and follow the instructions
Detailed instructions are included with each firmware. Contact support if you encounter issues.
Yes, ROSSMA equipment supports integration via standard protocols:
- Modbus RTU/TCP — for SCADA systems
- MQTT — for IoT platforms
- HTTP REST API — for cloud solutions
- LoRaWAN — via network servers (ChirpStack, TTN, etc.)
For integration assistance, submit a support request with the topic «Integration».
The serial number can be found:
- On the label/plate on the device enclosure
- In the device passport documentation
- In the device web interface (under «Information»)
Serial number format: ROSSMA-[model]-[year]-[number], e.g.: ROSSMA-IoT-2024-001234.
To submit an RMA:
- Fill out the support form describing the malfunction
- Provide the device serial number
- Wait for confirmation and an RMA number from our team
- Ship the device in original or protective packaging to the specified address
Warranty does not cover damage caused by misuse, mechanical damage, or unauthorized repairs.
ROSSMA equipment supports a wide range of sensors:
- Analog: 4–20 mA, 0–10 V
- Digital: RS-485 (Modbus RTU), 1-Wire
- Pulse: water, gas, and electricity meters
- Specialized: pressure, temperature, level, and flow sensors
A full list of compatible sensors is available in the documentation for each device model.
The choice of protocol depends on operating conditions:
- LoRaWAN — range up to 45 km in line of sight, battery life up to 10 years, ideal for distributed sites without cellular coverage
- NB-IoT — works over existing cellular infrastructure, great for urban sites with operator coverage
- LTE (4G) — real-time data transmission with minimal latency, suitable for mission-critical monitoring systems
For help choosing, contact our engineers through the support form.
Battery life depends on the device model and operating mode:
- Up to 10 years on built-in battery using LoRaWAN with 15-minute polling interval
- Battery life decreases with increased polling frequency and number of connected sensors
- Mains-powered devices (220V or 12/24V) operate without battery life limitations
Our engineers can calculate exact operating time for your configuration.
Yes, ROSSMA manufactures explosion-proof (Ex) equipment for potentially hazardous environments:
- Certified to explosion protection standards for the oil and gas industry
- Special enclosures for Zone 0, 1, and 2 areas
- Intrinsically safe circuits for sensor connections
Detailed Ex specifications are available in the documentation. Contact our specialists for equipment selection.
ROSSMA IIoT-AMS is a cloud platform for equipment monitoring and management:
- Web interface accessible from any device (PC, tablet, smartphone)
- Real-time monitoring of all connected sensor readings
- Threshold configuration and alerts (email, SMS, push notifications)
- API for integration with your systems
Register on the website or contact your account manager for access.
Communication range depends on the protocol used and terrain conditions:
- LoRaWAN — up to 45 km in line of sight, 3–5 km in urban areas
- NB-IoT — cellular operator coverage area
- Wi-Fi — up to 100 m indoors
- RS-485 (Modbus) — up to 1200 m via cable
We recommend a site radio survey for optimal equipment placement when designing a system.
ROSSMA equipment is designed for harsh industrial conditions:
- Temperature: −55°C to +85°C (depends on model)
- Enclosure protection: IP67 — full dust and water protection
- Aggressive environments: chemical resistance (Ex versions)
- Vibration and shock: industrial-grade durability
Exact specifications for each model are listed in the technical documentation.
To select the optimal solution, the following criteria are considered:
- Type and number of monitored parameters (pressure, temperature, flow, level)
- Operating conditions (temperature, humidity, explosion hazard)
- Battery life requirements and data transmission method
- Integration needs with existing systems (SCADA, DCS)
Use the project calculator on this page or contact our engineers for a free consultation.
The ROSSMA IIoT-AMS platform supports multiple data exchange formats:
- REST API — for integration with web applications and cloud services
- MQTT — for IoT platforms and message brokers
- Modbus RTU/TCP — for SCADA and DCS systems
- CSV — historical data export for analysis
Detailed API documentation is available for registered platform users.
