4.8.3 Default configuration of I/O pins
The built-in web interface of the terminal offers a page for configuring the I/O
pins.
The default configuration of the I/O pins is as follows:
• Pin 1: Radio silence acknowledge output.
This pin changes state from low to high as soon as deregistration
completes and transmission has stopped as a result of activating pin 3.
• Pin 2: Mute input.
When high (active) the terminal is muted so that the Phone/Fax interface,
the ISDN interface and the IP handsets do not ring, and the Ringer output
on pin 4 is silenced as well. The IP handset is allowed to indicate ringing
in the display. When the pin is low, the terminal is in normal operation.
• Pin 3: Radio silence input.
When high (active) the terminal observes Radio Silence. The terminal
gracefully closes all open connections, and deregisters from the BGAN
network. No transmission is allowed until the pin is deactivated.
• Pin 4: Ringer output.
This pin changes state from low to high when the terminal is notified of an
incoming call from the satellite interface. When the call is answered, or
the caller gives up and releases the call, the pin changes back to low.
• Pin 5: Ignition input.
Normally not used in maritime installations. Use Remote on/off in the
power connector instead.
Pin 7 (non-configurable) : Apart from the 5 configurable inputs/outputs, the DC
connector has an additional output pin, pin 7 DC output, which can be
connected to a ringer, relay or similar. The output voltage is 9-15 V, 50 mA.
For information on how to configure the I/O pins, see the user manual for the
SAILOR 500 FleetBroadband and SAILOR 250 FleetBroadband systems.
