for M2M/IoT Networking Applications

Industrial smart modem series designed for remote data transmission over cellular network.

Provides fast and reliable transparent data transfer via wireless GPRS or 3G channel using TCP/IP protocol. Besides, devices support connection over the back-up CSD channel.

Modems come with serial RS-232 and/or RS-485 ports, dual SIM card slots and a USB interface for easy modem configuring.

Application Areas
— AMR/AMI, smart metering (heat, electricity, water, gas)
— Transportation and security, alarm and alert systems
— Power and energy industry
— Remote monitoring



• GPRS, 3G
• CSD back-up channel


• Dual SIM card slots
• Watchdog timer PING/TCP connectivity check
• 2 years warranty


• Rugged metal IP30 case
• Sealed plastic IP65 case
• DIN rail and table mountable
• Convenient LEDs locations on the case to monitor the connection status and cellular signal strength.


• RS-232
• RS-485
• RS-485 isolated


• Remote configuring and firmware update via TCP, CSD, SMS
• Local configuring via USB
• More than 200 configuration parameters



Due to the built-in microcontroller, ADM modem appears to be a smart device and provides extensive configuration and management capabilities:

— Serial data to IP data conversion
—  TCP Client/TCP Server modes
—  Connection on schedule and on request to optimize the cost of communication services
—  PING/TCP connectivity check
—  Simultaneous connection to 5 servers in Client mode. Simultaneous connection of up to 5 PCs in Server mode

—  Time synchronization using NTP servers.
—  ADC input to ensure remote facilities monitoring
—  Power supply: DC 7~30 V
—  Wide operating temperature range: -40°C…+70°C
—  Local and remote configuration and firmware update. Convenient and user-friendly modem configuration software. More than 200 configuration parameters. Remote configuration via TCP, CSD or SMS


Continuous automated connection
ADM Smart Modems provide stable and permanent connection between hosts over TCP Internet and do not require entering AT commands or making a CSD call.

Data transfer at a speed high enough for AMR systems
GPRS - up to 85.6 Kbit/s
3G (UMTS) - up to 7.5 Mbit/s

When transmitting data over GPRS/3G, payment is charged not for the connection time, as in CSD mode, but only for transmitted data, which significantly reduces the cost of communication services. To save costs, the modem can also be configured to connect on a schedule or by command.
