wiring
Basic RS-232 connection between the radio modem (PORT1) and a typical PC (COM-
port):
NOTE!
When installing the cables of the serial interface, the operating voltage of all devices must
be off (POWER OFF condition).
Due to the greater current consumption of SATELLINE-3AS Epic operating voltage must be
connected to pins 14 AND 15, and ground to pins 7 AND 8. Correct fuse rating is in this
case 4 A (SLOW FUSE).
