RESTRICTIONS ON USE
SATELLINE-3AS(d) radio modems have been designed to operate on frequency ranges, the
exact use of which differs from one region and/or country to another. The user of a radio
modem must take care that the said device is not operated without the permission of the local
authorities on frequencies other than those specifically reserved and intended for use without a
specific permit.
SATELLINE-3AS(d)
(380…470 MHz) is allowed to be used in the following countries, either
on licence free channels or on channels where the operation requires a licence. More detailed
information is available at the local frequency management authority.
Countries*: AT, AU, BE, BR, CA, HR, CZ, CY, DK, EE, FI, FR, DE, GR, HK, HU, ID, IS, IE, IL, IT,

SATELLINE-3AS(d) 869 MHz
is designed to operate in the following countries listed below
on the licence free frequency band of 869.400 – 869.650 MHz (not incorporating the band
869.300 – 869.400 MHz) according to recommendation CEPT/ERC/REC 70-03. This
recommendation has been drawn up by the European Radiocommunications Committee (ERC)
under CEPT. The transmit/receive duty cycle of the individual unit is limited to 10% on this band,
and a single transmission period must not exceed 36 s. In addition, the maximum allowed
radiated output power is 500 mWERP.

INTRODUCTION
SATEL OY is a Finnish electronics and Telecommunications Company specialising in the design
and manufacture of wireless data communication products. SATEL designs, manufactures and
sells radio modems intended for use in applications ranging from data transfer to alarm relay
systems.End users of SATEL products include both public organisations and private individuals.
SATEL is the leading European manufacturer of radio modems. SATEL radio modems have been
certified in most European countries and also in many non-European countries.
Both the amount of data transferred, and the size of local area networks is increasing
constantly. SATEL has addressed these market requirements by introducing the SATELLINE-3AS
radio modem range. The SATELLINE-3AS can offer speeds up to 19.2 kbps and has a
selectable serial interface between 300 … 38 400 bps.
In addition to increased data transfer speed, SATELLINE-3AS also offers many other new
features. These include built-in support for RS-422 and RS-485 interfaces as well as the
standard RS-232 interface.
The SATELLINE-3ASd and SATELLINE-3ASd Epic models include a built-in LCD display, offering
the user both new features and increased flexibility. No longer do you have to rely on access to
a PC or terminal device to check or alter the configuration of the unit, now this can be achieved
by viewing the LCD-display and using the four (4) push buttons. The display is also a useful tool
in testing the radio connection between radio modems.
SATELLINE-3AS facilitates the construction of large radio networks using the built-in Message
Routing function, which is both fully transparent to the user and can be used with most system
protocols.
SATELLINE-3AS also offers option of error correction, utilising the FEC-method (Forward Error
Correction). FEC can be used to minimise errors caused by noisy channels.
SATELLINE-3AS radio modem operates in one of the 4 basic modes of operation: Data Transfer
Mode , Programming Mode, Test Mode or Standby Mode .
NOTE! This user guide version 2.7 is compatible with the radio modems marked with text “E2”
on the serial number label. All SATELLINE-3AS(d) modems delivered since mid-June 2004 are
equipped with this mark.

The power cable (+Vband GND) must be connected to a power supply with a proper output
voltage and with a minimum output current of 1 A (with the SATELLINE-3AS Epic the required
output current of the power supply is 5A). The DTR–pin of the serial line connector must also be
connected to a positive voltage.Detailed installation instructions can be found in Chapter 10.
When creating a test connection, you can either use the
SaTerm terminal program, (available for
free from authorised SATEL dealers or directly from SATEL Customer Support) or HyperTerminal
(which is included in most the Windows™ based operating system packages), or almost any
other terminal program. Basic settings for the serial port of the host computer, when using a
terminal program to communicate with SATEL radio modems, are as follows: ”COM1, 19200
bps, 8-bit data, none parity, 1 stop bit”. If the serial port designated as COM1 in the host
computer is reserved, any other free serial port in the host computer can be used (with the
settings listed).
If the DTR-pin is not connected, the radio modem will remain in STAND-BY mode and will
therefore not send or receive any data
Note: If you want to change the settings of a radio modem using the Programming Mode of
the radio modem with the help of an external terminal, the data speed of the terminal must
be

Basic connection between a radio modem and the serial port COM1 (RS-232) of a PC is
depicted in the schematic below.
NOTE THE WIRING ON THE DIAGRAM ABOVE!
The maximum voltage level at DTR pin
is +25 Vdc. Incase the operating voltage is greater, user must take care that the voltage at DTR
pin does not exceed +25 Vdc e.g. by using a resistive divider.
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 1 A(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).

Prepare installation of SATELLINE-3AS(d) modem into the SATEL-
321 casing
Before installing a SATELLINE-3AS(d) or 3AS(d) 869 modem into the SATEL-321 casing, the
battery pack function must be selected as follows:
1. Switch the radio modem into the Programming Mode, see chapter 4.2 Programming
Mode.
2. Select main menu selection “5” (Serial Port 2).
3. Enter selection “1” (Port Status).
4. Select “3” (BATT / LCD) for 3ASd or 3ASd 869 modems. Select “4” (BATT / NO LCD) for
3AS or 3AS 869 modems.
5. Save the setting.
6. Switch the radio modem back into Data Transfer Mode.
Please notice that both serial ports must be RS-232, NOT RS-485 / 422 and the SW –version of
the 3AS(d) modem must be V 2.16 or later.
Please check the installation advice from the SATEL-321 user guide, Chapter

radio modem into the SATEL-321 casing

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-3AS radio modem includes a 15-pin
‘D’-type female connector, 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 contains two separate serial ports, which are designated P
Port 1
and P
Port
2
. Only one port at a time can be used for communication.
Port 1
complies always with the RS-232 standard.
Port 2
can comply either with the RS-232, RS-422 or RS-485 standards. The interface type is set
at the factory according to the customer order. The interface type can be changed afterwards in
the programming mode by the user.
NOTE!
WHEN THE MODE-PIN (PIN 12 OF THE D-CONNECTOR) IS CONNECTED TO
GROUND, THE RADIO MODEM IS IN THE PROGRAMMING MODE AND P
Port 1
(PINS
7, 9, 11) IS THEN IN USE! If you normally use P
Port 2
for data transmission, the serial
cable must be changed to a suitable type when switching over to theconfiguration mode.
