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 OY 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 OY has addressed these market requirements by introducing the SATELLINE-3AS radio
modem range. The SATELLINE-EASy can offer speeds up to 19.2 kbps and has a selectable serial
interface between 300 … 38 400 bps.
In addition to wide 70 MHz tuning range; SATELLINE-EASy also offers many other new features.
These include built-in support for RS-422, TTL and LVTTL as well as the standard RS-232
interface, adjustable channel spacing and +3 … +9 V / +6 … +30 V voltage levels variations.
SATELLINE-EASy 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-EASy 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.
The radio modem also offers option of error correction, utilising the FEC-method (Forward Error
Correction). FEC can be used to minimise errors caused by noisy channels.

When creating a test connection, you can use Windows™ based SATEL Configuration Manager
(available for free from authorised SATEL dealers or directly from SATEL Customer Support),
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, 9600 bps, 8-bit data, none
parity, 1 stop bit”.
The power cable (+Vband GND) must be connected to a power supply with a proper output
voltage and with a minimum output current of 2 A (for +3 … +9 V PWR-module) and 1 A (for
+6 … +30 V PWR-module).
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 9600 bps.

2SERIAL 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 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 as P
Port 1
and P
Port
2
. Only one port at a time can be used for communication.
Port 1
Fixed - complies always with the RS-232 standard.
Port 2
Adjustable – settings are according to the interface module, which is installed at the factory. The
default module is a dual function RS-232/RS-422. When RS-232/RS422 interface is installed,
user can set on either RS-232 or RS-422. Other fixed options are LVTTL or TTL which must be
specified in the order. The user can set the Ports 1 and 2 ON/OFF afterwards in the
programming mode. Only one port can be in operation at a time.
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 the configuration mode.

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.
oGND = both the negative pole of the operating voltage and the signal ground.
oVb= positive pole of the operating voltage.
9.1 Operating Voltage
The SATELLINE-EASy radio modem can have two (2) operating voltage ranges. The range is
defined by the PWR-module, which is installed and set at the factory. I
If not specifically
agreed the default operating voltage is +6 … +30 V.
The operating voltage options are: +3.2 … +8.5 VDC or +6.5V … +28 VDC (+/-10%).
The nominal voltages are +3 … +9 V and +6 … +30 V. The Input Voltage range is marked
into the label.
Overvoltage behaviour
+3 … +9 V range:
1. When the operating voltage goes below +3 V, the modem will automatically switch OFF.
2. When the operating voltage range is exceeded, the modem will automatically switch OFF.
However, if the maximum value is more than +20 V, it may damage the module.
+6 … +30 V range:
1. When the operating voltage goes below +6 V, the modem will automatically switch OFF.

2.
When the nominal operating voltage is more than +33 V, it may damage the module.
2.1.1 Power supply
The radio modem must only be connected to a power supply with an adequate current output.
The pins 15 and 14 of the D-connector are connected to the positive power supply line. The pins
8 and 7 of the D-connector are connected to negative power supply line (ground).
The DTR-line of the radio modem, which is connected to pin 1, can be used as an
ON/STANDBY–switch, and in this way the radio modem can be switched either ON (operational
state) or OFF (STANDBY). The logical state "1" (Open or more than +3.0 V, max Vdc) of the
DTR-line corresponds to ON-state and a logical state "0" (.. <=0 V) corresponds to a STANDBY
state.
In applications, where the radio modem is used as a portable device (meaning battery operation),
the DTR-line (pin 1) should be connected to a logical state "0" always when it is possible to
conserve battery power and prolong operational time between battery charging.
NOTE! There is a galvanic connection between signal ground (SGND, pin 7), ground (GND, pin
8), outer conductor of antenna connector and modem casing.
The modem withstands a live insertion or removal from the DTE-unit without switching OFF the
power.
2.1.2 Fuse
A proper fuse must be connected in between the radio modem and the power supply. The correct
value depends on the model (see list below). Recommended value is 4 A slow.
Operating Voltage +3 … +9 V +6 … +30 V
Maximum Current 2.5 A 1 A

3USER INTERFACE - With/without display
3.1 LED-indicators
There are five (5) LED indicators on the front panel of the radio modem, and they give an
indication of the status of the serial port and the radio interface:
Description of the
LED-indicators:
1. RTS indicates the status of D-connector pin 13.
2. CTS indicates the status of D-connector pin 6.
3. TD indicates that the radio modem is receiving data via serial port.
4. RD indicates that the radio modem is sending data via serial port.
5. CD indicates the status of the radio interface. The status of the CD-signal on the serial
interface may differ from the status of the LED-indicator.
3.2 Display and push buttons
SATELLINE-EASy includes a LCD-display with a backlight. In the Data Transfer Mode the display
will show the operating settings of the radio modem, for example the radio field strength and the
supply voltage. By using the push buttons and the LCD-display, it is possible to change most of
the settings of the radio modem, without the need for an external terminal. The display backlight
illuminates automatically as soon as a button is pressed.
The radio modem will shift into the Programming Mode by pressing the SETUP-push button ( ).
When activated the menu shows a listing of the changeable parameters.
With the help of the main menu, sub-menus can be selected which in turn can be used to change
the settings. You can always return to the previous higher level of the menu structure by pressing
the CANCEL (or BACK) push button. Pressing the or button changes settings or moves in
the menu. Selections are confirmed by pressing the SELECT or SET button. In case of numerical
values the digit to be changed is selected by pressing the NEXT button (see following page).
