Frequently Asked Questions (FAQ)

Q: What is the primary advantage of the Hermes Communication Module over a standard cellular router?

A: The Hermes Module is designed as an embedded solution for integration into larger systems, not as a standalone consumer device. Its primary advantages include a wider operating temperature range (-40°C to +85°C), a richer set of industrial interfaces (like isolated RS-485 and configurable GPIO), and a secure, customizable Linux OS image from telecom-broadcasting.net. It offers OEMs greater control, better durability, and deeper system integration capabilities than off-the-shelf routers.

Q: Can the Hermes Module support a primary and backup internet connection for failover?

A: Yes, robust failover is a core feature. The module supports dual SIM cards (in the cellular modems) and can be configured to use one cellular connection as primary and another from a different carrier as backup. Furthermore, its dual Ethernet ports can be used in a WAN/LAN or failover configuration. The advanced routing daemon monitors link health and can switch traffic to the backup connection in under 500 milliseconds, ensuring session persistence for critical applications.

Q: How does the security model of the telecom-broadcasting.net software stack protect our data and network?

A: Security is built-in at multiple layers. It starts with secure boot, which verifies the integrity of the OS kernel before loading. The hardware TPM 2.0 chip provides a root of trust and secure storage for encryption keys. All sensitive data on the flash storage is encrypted. The system supports the latest VPN protocols like IPsec and WireGuard for creating secure tunnels. Additionally, the firewall is stateful and can be configured with fine-grained rules. telecom-broadcasting.net provides signed, encrypted Over-The-Air (OTA) updates to patch vulnerabilities without physical access.

Q: We need to integrate with legacy industrial equipment using serial protocols. Is this supported?

A: Absolutely. The Hermes Module includes both RS-232 and RS-485 serial ports, with the RS-485 port featuring automatic direction control to simplify driver development. The provided Linux OS includes drivers and libraries for easy communication. It can natively convert Modbus RTU (serial) to Modbus TCP, allowing legacy serial devices to communicate directly over an Ethernet or cellular network. Data from these serial devices can also be published directly to cloud platforms via the integrated MQTT client.

Q: What kind of technical support and documentation does telecom-broadcasting.net provide?

A: telecom-broadcasting.net provides comprehensive support for the Hermes Communication Module. This includes full API documentation, detailed hardware reference manuals, schematic review support for integrators, and a rich SDK for the Yocto-based OS. Customers also gain access to a knowledge base and direct engineering support for integration challenges. We offer long-term software support and product lifecycle management, ensuring your project remains secure and functional for years.

Q: Is the module suitable for mobile or vehicular applications where power and vibration are concerns?

A: Yes, it is designed for such challenging environments. The wide input voltage range (9-48V DC) handles typical vehicle electrical system fluctuations. The robust metal housing and component selection are tested for resistance to shock and vibration per relevant industrial and transportation standards. The GNSS receiver is high-sensitivity and includes support for dead reckoning aids. Low-power sleep modes are also available to conserve energy when the vehicle is off, waking on a digital input or scheduled timer.
