PPS Time Mark Input
When used with an external ARINC 743A position source, the time mark signals from the
navigation sensor are connected to the ADS600-B time mark input pins (P1-2 and P1-21).
3.7.5
Serial Interfaces
The ADS600-B provides two bi-directional RS-232 serial interfaces, one receive only RS232
interface, one transmit only RS232 interface, one bi-directional RS-422 interface and one
ARINC 429 input/output. These serial interfaces can be connected to:
