4.4.1 Pin Locations and Connections
The identification letters and descriptions for the 19-pin System Connector and 10-pin
Data Connector, located on the front of the ISAT-100, are listed in Tables 4-1 and 4.2
and illustrated in Figures 4-3 and 4.4 respectively.
Both Pin B and Pin C on the System connector must be grounded in order to
enable the internal battery.
Use AWG 20 wire to hook up the 28VDC aircraft main power source protected
through a 3 Amp breaker to the ISAT-100. It is important to remember that the ISAT-
100 will sense the onrush of 28VDC and will send this event, together with a
timestamp, to the dispatch centre in order to signal the beginning of a flight. Thus, the
ISAT-100 should receive mains power as soon as the aircraft’s master or avionics
switch is turned on. The remaining Pins on J1 are reserved for future firmware
implementations.
