【FEATURES】
-NND-300 is a NMEA distributor/buffer to provide 8 NMEA outputs (1x8/2x4) from 2 inputs.
-The baud rate can be up to 115200bps from 4800bps, while the default rate is set as 4800bps.
-With a built-in optical-coupled isolator, the distributor is a reliable and professional device, which can be used on board. The external equipment connected to the distributor can be safely protected from lightning surges on line.
-NND-300 includes two modes:
Mode | Buffer |
1 input / 8 outputs | Input 1 → Output 1 ~ Output 8 |
Input 2 → Output 1 ~ Output 8 | |
2 inputs / 4 outputs each | Input 1 → Output 1 ~ Output 4 Input 2 → Output 5 ~ Output 8 |
Input 2 → Output 1 ~ Output 4 Input 1 → Output 5 ~ Output 8 |
