19.1 Transmit Inhibit Function
In order to comply with FCC regulations, an external push button has to be installed on Maritime
VSAT installations, making the VSAT transmitter to stop transmission within 100 ms after
pushing the push button. .
A SatLink 1910 with SatLink 100 plug-in card installed is capable of interfacing an external
push button to implement this “transmit inhibit” function,” typically being used to avoid
exposing people that has to work in the area around the antenna to the transmitted signal. When
transmit inhibit mode is cleared by releasing the external switch, the transmitter will be re-
enabled.
The transmit inhibit switch is connected to the SatLink 100 plug-in card at the two center pins of
the RJ11 connector, as shown in Figure 1 below. When short-circuited, the transmit inhibit
function is activated.
