The AMI Marine X14-DB 4 Channel Data Buffer is a marine data distribution unit designed to receive serial navigation data from a single source and distribute it to four independent output ports. It supports multiple signal types, including RS-422, RS-232, current loop, and 5 V TTL, making it suitable for interfacing compatible marine navigation and communication equipment. The unit provides electrical protection against overvoltage, overcurrent, surge voltage, and reverse polarity, ensuring reliable data distribution across shipboard systems. It is commonly used to share NMEA 0183 data between equipment such as GPS receivers, gyrocompasses, speed logs, and other compatible bridge instruments.
