Host Port
The host port is the port that connects to a PC, laptop, smartphone, PDA, tablet or any device that is
connected to the multiplexer to receive the combined NMEA data for processing and display. The type of
host port differs for each type of multiplexer and some multiplexers have two host ports.
The host port is always bi-directional: it delivers the combined NMEA data from the NMEA inputs to the
host and it also receives NMEA data from the host to be sent to the NMEA outputs of the multiplexer. The
host port is also used to configure the multiplexer and to update its firmware.
There are two types of host ports: wired ports like RS-232, USB and Ethernet and wireless interfaces like
WiFi and Bluetooth. Both types work equally, have equal priority and can be used simultaneously.
The only restriction of the wireless interfaces is that they cannot be used to update the firmware of the
MiniPlex. See chapter “Firmware Update” for more details.
The following chapters describe each type of host port. The applicable type of multiplexer is listed
underneath the caption.
