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/TC 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, BE, BG, CY, CZ, DK, EE, FI, FR, DE, GR, HU, IS, IE, IT, LV, LT, LU, MT, NL, NO,

WARNING! Users of SATELLINE-3AS/TC radio modems in North America should be aware, that
due to the allocation of the frequency band 406.0 – 406.1 MHz for government use only, the use
of radio modem on this frequency band without a proper permit is strictly forbidden.

1 INTRODUCTION
SATELLINE-3AS/TC is a member of the versatile SATELLINE-3AS radio modem family.
Consisting of a data modem and a UHF radio transceiver, it provides a wireless, transparent and
half-duplex serial data link with other similar radio modules or compatible SATELLINE radio
modems manufactured by SATEL Oy.
SATELLINE-3AS/TC is designed for integration into the terminal equipment. The component
blocks are shielded by metal plates, but the housing and the related mechanics are supplied by
the client. Also the EMC characteristics of the radio module are completed for the combined
equipment.
A number of new SL commands has been implemented to the modem controller software for full
control of the features of SATELLINE-3AS/TC in integrated use.
The implementation of SATELLINE-3AS/TC is based on the widely used SATELLINE-3AS radio
modem – the radio communication and the user interface are similar. The main differences to
SATELLINE-3AS are:
1. SATELLINE-3AS/TC is delivered without the housing – only the two PCBs (the logic board
and the RF board shielded as a one card) are supplied by SATEL
2. Antenna connector is a female MMCX connector.
3. The antenna circuitry of the radio module includes an additional filter on GPS frequencies
in order to avoid any interference to the GPS receivers.
4. The main header is a 32-pin Eurocard connector type B.
5. The operating voltage must be 6.5V…18VDC.
SATELLINE-3AS/TC has two pins in the header connector for controlling the external LED
indicators, the one for the external green LED and the other for the red LED. By different
combination of the LED status, the user of the application device can monitor the status of the
SATELLINE-3AS/TC radio module.

3 USER INTERFACE
The user interface of SATELLINE-3AS/TC is basically similar to the standard SATELLINE-3AS radio
modem – the data handling, configuration or the control of the device.
The user guide of SATELLINE-3AS raio modem provides the detailed functional description of
SATELLINE-3AS/TC. Only the details specifically applied for SATELLINE-3AS/TC and its use in the
client’s system are specified in this document.
3.1 LED indicators
SATELLINE-3AS/TC has two pins (GRN_LED and RED_LED) in the header connector for
controlling the external LED indicators. GRN_LED controls the external green LED and RED_LED
controls the external red LED.
The radio module itself does not have any LED indicators.
The operation of the LED indicators is different in the “normal” mode and in the FCS (Free
Channel Scan) mode. The operation is specified by the two tables below.
3.1.1 SATELLINE-3AS/TC – LED INDICATORS in the NORMAL MODE
LED status Description
No light Modem is turned off
Green flashes Modem is in receiver mode
Solid green (non-blinking)
Radio Link established. Modem has received data within last 5
seconds
Solid green + red blinks Modem is receiving data
Solid red Modem is in transmitter mode
Red blinks + green blinks Modem is in command mode
Note: In Normal operation all modems are in receiver mode by default, and red led is on only
during the transmission of data.
3.1.2 SATELLINE-3AS/TC – LED INDICATORS in the FCS MODE
LED status Description
No light Modem is turned off
Green flashes Modem is in receiver mode
Solid green (non-blinking)
Radio link established. Modem is ready to receive data.
FCS Slave modem has found the transmitter.
Solid green + red blinks Modem is receiving data
Solid red Modem is in transmitter mode
Red blinks + green blinks Modem is in command mode
Note: In FCS mode FCS master modem is always in transmitter mode.
