NAL Replaces Tera 9523 Modem
We are pleased to announce that as of 1st December, 2024, MetOcean will offer the A3LA-R and A3LA-RS from NAL RESEARCH for 9523 serial controller devices. The NAL products are mature and well regarded in the Satellite IoT field, and we believe these high-quality products will provide excellent service for your applications.
Please note that we will no longer offer the similar 9523-based TERA product.
MetOcean is also developing a new STREAM device that will implement the new 9704 IMT Transceiver from Iridium. The STREAM IMT is compact, low-power, and engineered for longevity. Coming early 2025, the new STREAM IMT will feature:
- Pass-Through Serial Communications
- On-Board Power conditioning
- Quick to market enablement!
