Splitter Function
The easy TRX2 devices with the suffix „IS“ have an antenna splitter
integrated. This splitter checks whether the output comes from the VHF
device or from the Class B AIS Transmitter to the antenna. If this is the
case, the other connected devices are disconnected very fast. By doing so
the output is sent to the antenna and not to the other devices.
CAUTION:
It is not allowed to connect a radio device to the antenna port of the
easyTRX2-IS - this may cause destruction of the internal AIS receiver.
The Class B AIS Transceiver has to disconnect the other connected units
very fast (< 1 ms) when sending an AIS message. The reason for this is that
the Class B Transceiver has to build up its transmission power according to
standards and thus needs a splitter, which disconnects the other units
even faster from the antenna. During usual reception mode all devices are
connected with the same antenna.
