SI-TEX SAS-300 AIS Class B Transceiver – Display Only f/Use w/Existing AIS

Description

Keep AIS target information visible on a dedicated screen with the SI-TEX SAS-300 AIS Display Terminal. Its 5-inch color LCD and NMEA 2000/NMEA 0183 connections provide a separate AIS viewing and control point for vessels that already have a compatible AIS receiver or transceiver onboard. Need to monitor AIS data without tying up the main chartplotter screen? The SAS-300 connects to an existing AIS system, displays received target information, and can be mounted at the helm using a flush panel or trunnion bracket.

Key Specifications

• SI-TEX SAS-300 dedicated AIS display and control terminal.
• Designed for use with a separately installed compatible AIS transceiver or receiver.
• 5-inch high-contrast color LCD display.
• NMEA 2000 and NMEA 0183 data interfaces.
• No AIS transmitter, receiver, GPS receiver, VHF radio, antenna, or MMSI programming function included as a standalone display.
• No wireless connectivity.
• 12V/24V DC input with up to approximately 5W maximum power consumption.
• IPX5 protection for a protected helm display installation.
• Operating range of 5°F to 131°F (-15°C to 55°C).
• Approximate dimensions: 6.3 × 4.3 × 2.4 inches; approximate weight: 1.1 lb (0.5 kg).
• Trunnion bracket or flush-panel mounting.

Integration

The SAS-300 is a display terminal only and cannot receive or transmit AIS data by itself. It requires a compatible AIS transceiver or receiver, the correct NMEA 0183 or NMEA 2000 connection, and any antennas, GNSS source, or MMSI programming needed by the connected AIS unit.

A dedicated AIS display can supplement a chartplotter, but it is not a radar, VHF radio, chartplotter, emergency beacon, or collision-avoidance system. AIS target data depends on the connected receiver/transceiver, antenna installation, VHF coverage, and other vessels transmitting accurate information.

Installation Notes

Mount the display in a protected helm location where it is visible and easy to operate without obstructing steering or other controls. Route NMEA and power cables through protected paths away from heat, chafe, standing water, and high-current wiring. Use correctly fused 12V/24V power and follow SI-TEX mounting and network-termination guidance.

Configure the connected AIS transceiver/receiver and verify that targets, vessel information, alarms, and displayed data are correct before regular operation. Inspect the display seal, mounting hardware, and cable connections routinely.

Before Ordering

Confirm the existing AIS unit is compatible, identify required NMEA 0183 or NMEA 2000 connections, verify helm mounting space, check 12V/24V power availability, and determine whether a dedicated AIS display is needed alongside the vessel chartplotter before ordering.
