MarineTraffic SLR300N AIS receiver

The SLR300N seamlessly connects to a PC or network port, facilitating direct viewing or sharing of AIS data on a local network. Additionally, it can be remotely mounted and configured to transmit AIS data via the Internet to a fixed IP address for use on a dedicated server.

However, please remember that this device has become obsolete and has been replaced by newer models for several years. As a result, it is no longer actively distributed to partners.

Wiring Diagram

MarineTraffic SLR300N Wiring Diagram

LED Status

The green LED (POWER) shows that the device is on. If no green light appears, recheck the power connection.

The two red LEDs (A/B) blink from time to time when the device receives AIS data. If one of the red LEDs does not blink irregularly, check the antenna, the coax cable, and the cable connections. It indicates that the device does not receive AIS data.

The orange Link LED on the network port flashes three times at a fixed interval if no network cable is connected or nothing is connected to the other end of the network cable. In this case, check the network cable and the connection.

The orange Link LED on the network port is permanently on when a connection has been established to a network device (e.g., switch).

The green Activity LED on the network port only flashes when a connection has been established (see orange LED). It does not mean that the data is being transmitted to MarineTraffic.

USB Connection

The USB port on the device can also be used to transfer AIS data to your computer. To do this, you'll need a USB cable with a USB-A to USB-B connector. This lets you connect the device to your Windows PC, Mac, or Linux PC. You'll need additional drivers for Windows use, although the device is usually recognized automatically on other operating systems.

You can find drivers here or on the official Comar website. If you're unsure about the installation, please seek assistance from a specialist who can help you.
