SATELLINE RADIO MODEMS
SATELLINE-3AS(d)
SERIAL PORT SETTINGS
SATELLINE-3AS(d) radio modem consists of two serial ports. Port1 is always RS-232. Port2 can be set
by hardware to be either RS-232 or RS-422/485. Details of changing the hardware settings of port2
are enclosed. The selection between RS-422 and RS-485 is made by external wiring. More
information of these differential interfaces can be found in the Satelline-3AS user's guide.
When Port1 is set active, Port2 is non-active and vice versa. So the both ports can not be used
simultaneously.
The both serial ports are wired to the same 15-pin D-sub connector. Pins 2, 3, 4 and 5 are
multifunctional. The following table shows the functions of the pins for different settings.

• Instructions for changing the setting of the serial port2 from RS-232 to RS-422/485 (or vice versa)
The current setting of the Port2 can be checked in the setup mode. If the setting (written in the square
brackets after the list of the other settings of the port2) is not the one needed, the following hardware
and software modifications are required.
Open the back cover of the Satelline-3AS carefully keeping simultaneously the antenna connector
at its place.
Open the hex screws of the D-connector
Lift carefully the D-connector end of the circuit boards until you have access to the small 10 dip
switch matrix on the modem PCB. Caution! 3ASd will require some special care, to avoid a risk of
braking the display module. The metal fixing part of the display at the antenna side has to be
loosened slightly before lifting the PCBs.
Move the switches to the correct positions. Refer to the table below.

# Switches 1 to 5 are for setting of the Port2. Switches 6 to 8 are for software boot loading. Switches 9 and 10 are not in use.
Close the radio modem carefully. Please note that the four screws of the back cover of 3ASd are
not equally long. The shorter ones have to be mounted to the antenna side. Longer screws break
the display if mounted to the wrong holes.
Enter to the setup mode according to the user´s guide.
Type * (=asterisk) for to enter the factory setup menu
Change the setting of the Port2 to the correct value (same as the switches)
Return to the main menu and check all the other settings to be as required.
Exit the setup mode
Please note that the warranty of the radio modem will expire if the device has been opened by
unauthorised person.
• Other port settings
For Satelline-3AS(d) radio modem the following serial port settings have to be defined for proper data
communication.
Data speed Data speed at serial port is selectable from 300 up to 38400 bps. Bit rate
over the air is constant and depends only on the channel spacing, i.e.
9600 bps for 12.5 kHz, and 19200 bps for 25 kHz. 3AS(d) link may act
as a data speed converter in the system. Data speed can be set to a
different value at the ends of the link.
Number of data bits 7, 8 or 9
Parity None, Even or Odd
Number of stop bits 1 or 2 Start, stop and parity bits are not transferred via the radio. They are
generated at the other end according to the serial port settings.
