FAQs
Does this module include a built-in GPS receiver?
No, the HS-MX1203GT module itself does not have a built-in GPS. It requires an external active GPS/BeiDou antenna connected via its MCX-female connector to obtain its own position, which is essential for transmitting AIS messages.
What is the default configuration, and how do I program it for my vessel?
The module ships with generic factory settings. You must configure it with your vessel's specific MMSI number, name, and call sign using our provided AIS CONFIGURATION PC software and a TTL-to-USB adapter cable. Once configured, these details are stored in the module.
Can I temporarily turn off the AIS transmission (Silent Mode)?
Yes. The module features a SILENT pin. By pulling this pin low (to GND), you can disable AIS transmission for privacy or in security-sensitive areas while continuing to receive AIS data from other vessels.
What kind of antenna should I use with this module?
You need two separate VHF antennas:
A dedicated GPS/GLONASS/BeiDou active antenna for the GPS port.
Using high-quality, properly installed antennas is critical for optimal performance.
A dedicated AIS VHF antenna for the VHF port.
I'm designing a new device. Is technical documentation available?
Yes. We provide comprehensive documentation for integrators, including:
