RM2 — HF & V/UHF Data Modem

Overview

The RM2 is a compact HF and V/UHF data modem engineered for governmental and NGO users requiring reliable long-distance data communication links. It features adaptive equalization to mitigate in-band distortion, extending range and maximizing data throughput across desktop, vehicular, and marine installations.

Technical Summary

• Waveform Support: MIL-STD-188-110A/B, Appendix C, STANAG 4539, and STANAG 4415.
• Bandwidth: Configurable at 3, 6, 9, 12, or 24 kHz.
• Interfaces: Serial and Ethernet via RapidM RIPC/RAP1 protocol; 600 Ohm audio and PTT for radio interfacing.
• Power: Surge-protected 6–36 V DC input.

Operational Use Cases

Designed to support critical communication networks, the modem facilitates secure data transfer for governmental and NGO operations. Its high-performance Doppler tracking maintains reliable data links during mobile operations with relative speeds up to 250 km/h, making it highly effective for fast-moving vehicular and marine deployments.

Deployment Environments

The modem integrates seamlessly into desktop command centers, mobile vehicles, and maritime vessels. It is engineered to operate reliably in mobile environments utilizing a vehicle surge-protected 6–36 V DC power supply.

Performance Metrics

• HF Data Rate: Up to 9600 bps in 3 kHz bandwidth.
• V/UHF Data Rate: Up to 128 kbps in 24 kHz bandwidth.
• Doppler Tracking: Maintains operation at up to 250 km/h relative speed.

Setup & Portability

The compact form factor allows for straightforward integration into existing radio systems. Setup involves connecting the 6-36 V DC supply and interfacing with the host radio using industry-standard 600 Ohm audio lines and a PTT line. System control is managed directly via serial or Ethernet connections.

Compatibility

The RM2 interfaces with standard radios utilizing 600 Ohm audio and PTT lines. It supports standard HF waveforms including MIL-STD-188-110A/B and STANAG 4539/4415. An optional 2G ALE function (MIL-STD-188-141B) is built-in and can be activated via a license key.

FAQs

• How does mobility affect VHF data communications? Mobile operations can experience fading due to multipath interference when direct and reflected signals combine. Verify that the selected data modem features Doppler tracking to maintain data throughput at high relative speeds.
• What power supply considerations apply to vehicular and marine modem installations? Mobile platforms experience power fluctuations and surges. Verify the equipment's input voltage range matches the platform's supply and utilize surge-protected DC inputs to prevent damage to the communications hardware.
• How is modem bandwidth matched to existing radio capabilities? System bandwidth must align with the transceiver's capabilities to optimize throughput and prevent signal distortion. Confirm the modem offers configurable bandwidth settings, such as 3 to 24 kHz, to match specific HF or V/UHF radio interfaces.
• Problems we solve: where do we start with incomplete requirements? An incomplete specification can make product selection difficult. Start by sharing the task, operating environment and known constraints with Cyntony so the team can help define what to verify and which options are worth discussing (Our process).
• Outcomes we deliver: what comes from working through the requirements? The practical outcome is a requirements-led set of product options to evaluate with Cyntony. Confirm performance, compatibility and any service scope for your configuration before selection (Our process).
