MD94DDU DATASHEET

Product catalog summary

Overview: The MD94DDU is a NMEA 0183 Data Distribution Unit designed to handle two independent NMEA 0183 inputs and distribute a buffered output to up to nine devices. It can be daisy-chained with another unit for additional outputs, facilitating the relay of digital heading data or other NMEA 0183 data across a vessel. The unit is finished in Jet Black to match other marine navigation equipment and includes additional pass-through terminals in the MD94DDU+ model for user-defined wiring.

Applications: The unit allows for the distribution of individually buffered NMEA 0183 signals to multiple devices and supports common dimming of connected instruments.

Accessories: Includes the MD01/PMD Rotary Remote Dimming Control.

Related Products: Compatible with any NMEA 0183 compliant device, Transmitting Heading Device Systems, and Marine Data Repeaters.

Features: The MD94DDU is designed for NMEA data distribution with 2 inputs and 9 outputs, mappable inputs to outputs, power and remote dimmer connections, and a rugged aluminum enclosure. The MD94DDU+ offers 10 extra pass-through terminals.

Operational: The unit supports NMEA 0183 distribution with a buffer function at 4800 - 38400 Baud and has an MTBF of over 30,000 hours.

Environmental: Complies with IEC 60945 for protected areas, operates between -15°C to +55°C, and is RoHS compliant.

Approvals: Complies with IEC 60945 and IEC 61162-1, with DNV GL type approval.

Physical: Weighs 1.5 kg, dimensions are 254 mm x 254 mm x 70 mm, and it features an aluminum alloy enclosure with a fine-texture powder coat finish.

Electrical: Supports single or dual 24 V dc power supplies, with data inputs and outputs compliant with IEC 61162-1 and IEC 61162-2 standards. Outputs provide 24 V dc power at 500 mA max.
