SATELLINE-EASy Pro

User Guide v.1.5

4 SERIAL INTERFACE

The radio modem is referred to as DCE (Data Communication Equipment) whereas the PC is

referred to as DTE (Data Terminal Equipment). SATELLINE-EASy Pro includes a 8 pin ODU which

contains all the connections required to establish communication between the radio modem,

acting as the DCE, and the PC, acting as the DTE.

All EMC-requirements set forth by authorities have been taken into account in the design of the

radio modem. The radio modem user is thereby not required to take any special actions

regarding EMC-shielding (of the radio modem).

The radio modem has one serial port, Port 1 which complies with the RS-232 standard.

Description of pins:

 RD = Receive Data. Output of the data received from the radio modem to the DTE.

 TD = Transmit Data. Input of the data to be transmitted from the DTE to the radio modem.

 CTS = Clear To Send.

 RTS = Request To Send.

 MODE = operational mode. When the MODE-line is connected to ground (GND), the

radio modem enters the Programming Mode, which is used to change the settings of the

radio modem (i.e. configuration, set-up). If the MODE-line is not connected, the radio

modem will enter the Data Transfer Mode, in which data can be transmitted and received.

The Programming Mode is used only when installing a radio modem and changing the

operational parameters of a network. Normally the radio modem is always in the Data

Transfer Mode.

 GND = both the negative pole of the operating voltage and the signal ground.
