6 CONNECTION INTERFACES

6.1 RS-232 interface

RS-232 standard defines the method of serial data transfer between a computer and its

peripherals. The definition includes both the interface type and signal levels. Most computers and

peripherals contain one or more RS-232 type serial ports. The RS-232 standard uses transmission

lines, in which each single signal line level is referenced, to a common ground level. RS-232 has

been designed to be use in serial transfer of data, in situations where the distance between

communicating equipment is less than 15 m. The otherwise useful RS-232 standard is applied in

a multitude of slightly differing ways, (e.g. different pin configurations) and for this reason different

computers and peripherals are not necessarily directly compatible with each other.

6.2 Connectors

The device adopts a high standard waterproof ODU 8-pin data connector. Antenna connector

type is 50 Ohm TNC female.
