Description
DEVICE: NMEA BUFFER
BRAND: ALM TECHNOLOGY
TYPE: NBV0.3
NBV0.3 is a highly efficient NMEA splitter designed to correct and amplify NMEA signals. It features 6 independent outputs, allowing multiple NMEA devices to be connected without the risk of interruption due to overloading of the NMEA bus.
The data inputs are optically isolated, and the power input is electrically isolated for added safety and signal integrity.
