Splitter Function
The easy TRX2S 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 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
INPUT PORT (RIGHT SO239-CONNECTOR) – THIS MAY CAUSE
DESCTRUCTION 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.
