Product Description
Function:
The AMX21/HS switching unit expands the redundancy concept on to the antenna. A receiver can now be connected with two antenna/converter units. If an antenna fails or provides poor reception, the switchover to the other antenne will be done either automatically or manually, depending on the pre-selected mode.
The switchover between the two antenna/converter units can occur manually as well as automatically. A switch is available for choosing between the two operating modes. In the "Manual" mode a second switch can be used for direct switching between the two antennas.
In "Auto" mode the switching between the antennas depends on the number of visible satellites. This information is transmitted via time string (NMEA GGA format). The NMEA Time String is generated by the connected GPS receiver.
