Basic connection between a radio modem and the serial port COM1 (RS-232) of a PC is
depicted in the schematic below.
When using the SATELLINE-3AS , the operating voltage can be connected to either pin 14 or
15, and the power supply ground to either pin 7 or 8. Fuse size is 630 mA (slow).
When using the SATELLINE-3AS Epic model, the operating voltage must be connected to pins
14 AND 15, and the power supply ground to pins 7 AND 8, due to a larger current
consumption. Fuse size is 4A (slow).
