ADS-260 User Guide 4
1. Introduction
Sigfox is a communication protocol that is used to read data from sensors through a
fixed network of base stations. It works like a low cost “SMS” service. As an end-user,
you only need to buy a subscription to connect to the data network operated by
SIGFOX. Sigfox uses Ultra Narrow Band (UNB) radio technology and operates in the
license free bands (ISM). Sigfox has the advantage of covering larger areas than
other fixed local systems.
ADS-260 is an ultra low power, battery powered end node for the Sigfox network. The
units is available for the 868 to 869 MHz and 902 to 928 MHz bands. It incorporates a
configurable input (digital, pulse counter or analog) and multiple excitation options for
powering transducers. The device supports acquisition of up to 8 measurement
channels, based on the popular SDI-12 communication protocol and 8 channels,
based on the MODBUS protocol. ADS-260 can send up to 140 uplink messages per
day. The unit incorporates a Lithium Thionyl Battery supplying system operation for
up to 10 years.

ADS-260 User Guide 5
2. Operation modes
Modes of operation include:
1. Battery supplied cyclic operation.
2. External power adaptor supplied cyclic operation. The transition between the
two operation modes is uninterruptible.
3. Operation suspension for the device configuration.

WARNING: Pay attention to the correct polarity during battery
installation! The right polarity is marked up on the Battery Holder. The unit is
protected against reverse polarity.
3.5 Wiring the digital (Counter) Input
COM: GND
Digital Input states are:
Contact closed  Input state: ON (logical ‘H’)
Contact open  Input state: OFF (logical ‘L’)

ADS-260 User Guide 8
3.6 Wiring the analog input
ADS-260 incorporates 1 analog input with 12 bit resolution. The Analog input is
scanned according to the selected message transmission period (see 4.5.2).
For current measurements, an external 47R/0.25W resistor can be applied between
the input terminals (J6-1 and J6-5) on IN1.
ADU-260 incorporates two excitation outputs (12V, 5V) to supply external
transducers. The excitation output switches ON/OFF according to the selected
message transmission period (see 4.5.2).
Low power transducers are recommended for preserving longer battery lifetime.
The unit performs 100 consecutive readings of the analog input for every sample,
thereby neglecting the maximum and minimum values and calculates the average of
the remaining 98 values.

3.7 Wiring the SDI-12 Serial Bus
SDI-12 is an asynchronous, ASCII, serial communications protocol that was
developed for intelligent sensory instruments that typically monitor environmental
data. The communication is achieved by digital communications. The addressing
system allows data recorder to communicate with several microprocessor-based
sensors over a single line.
ADS-200 is compliant to the SDI-12 Standard Version 1.2 and supports extended
commands for sensor configuration, in terminal mode. ADS-200 can collect data from
several SDI-12 sensors for a total amount of 8 measurement channels.
SDI-12 connections:
J6-2: SDI data line
J6-1: GND
J5-2: 12V excitation output. The 5V excitation output (J5-3) can be used instead, for
sensors with a 5VDC supply option.
It is recommended to read the sensor manufacturers’ Sensor Manual and the SDI-12
Specification by the SDI-12 Support Group [1] before utilizing the corresponding
functions of the ADS-260 device.
3.8 Wiring the RS-485 Bus
ADU-500 supports the popular MODBUS protocol over a differential RS-485 bus. The
bus line is internally terminated with a 120Ω resistor.

4.3 Configuring the SDI-12 channels
ADS-260 supports up to 8 channels.
The configuration command for a SDI-12 channel is:
1230,n,a,m,i
1230: Command ID
n: Channel number (1-8)
a: Sensor address
m: Measurement set (0 for the aM! command, 1-9 for the aM1!–aM9! commands)
i: Parameter
ADS-260 addresses the SDI-12 sensors using the basic measurement starting
commands aM! (aMx!) and the D0!...D9! send data commands.
4.3.1 SDI-12 acquisition scheme
ADS-260 sends a start measurement command to the SDI-12 serial bus:
aMm!
where,
a: sensor address
M: Start measurement command
m: void or 1-9, Measurement set (aM! or aM1! to aM9!)
This command tells the sensor with address ‘a’ to take a measurement.
The sensor responds with:
atttn
where,
a: sensor address
ttt: the specified time, in seconds, until the sensor will have the measurement(s)
ready
n - the number of measurement values the sensor will make and return in one or
more subsequent D commands; n is a single digit integer with a range of 0 to 9
ADS-260 waits for either of two events to occur before issuing a D0 command:
1) receipt of a service request (a<CR><LF>) from the sensor
2) the specified time to elapse (ttt seconds)
ADS-260 issues one or more read commands (aD0! to aD9!) to read the
measurement parameters. Each parameter corresponds to one channel according to
the channel configurations:

ADS-260 User Guide 13
aD0! (aD1!...aD9!)
The addressed sensor responds with:
a<values><CR><LF>
where,
<values> - pd.d
p - the polarity sign (+ or -)
d - numeric digits before the decimal place . - the decimal point (optional)
d - numeric digits after the decimal point. the maximum number of digits for a data
value is 7, even without a decimal point, the minimum number of digits for a data
value (excluding the decimal point) is 1, the maximum number of characters in a
data value is 9 (the (polarity sign + 7 digits + the decimal point))
Example:
A soil measurement sensor returns three parameters:
1. Soil moisture in Water fraction by Volume (wfv)
2. Soil Conductivity in Siemens/Meter (S/m)
3. Temperature in °C
Two sensors (addresses 1 and 2) are connected to the SDI-12 serial bus.
The configuration commands are:
1230,1,1,0,1
1230,2,1,0,2

ADS-260 User Guide 15
4.5 Data Acquisition Parameters
4.5.1 Sampling delay (Warm up time)
The parameter defines an idle period between switching on the excitation and reading
the measurements from the analog and the SDI-12 channels. This option should be
set according to the transducer with the longest warm up time for stable reading. The
value of this parameter affects strongly the battery life.
1291,d
d: 0-255 sec
4.5.2 Message transmission period
The parameter defines the message transmission period to the Sigfox network. The
period should be set according to the number of channels selected for acquisition.
Every message contains one channel. The minimum value is 10 minutes in order to
satisfy the limitation of 140 messages per day. The value of this parameter affects
strongly the battery life.
1292,p
p: 1-255 min
4.6 Message Format
The message is in ASCII format and has a fixed length of 12 bytes.
L1 L0 D9 D8 D7 D6 D5 D4 D3 D2 D1 IN

5. Programming the unit
The way to enter the unit setup mode is the following:
1. Install the USB driver on a PC.
2. Connect the USB port to a PC. The Status LED is lighting for 2 sec.
3. Put a Jumper on JMP1. The Status LED starts blinking, indicating setup mode.
Program execution is suspended.
There are two ways to program the unit:
1. Connecting the unit to a PC and using a terminal program to pass the ASCII
commands to the unit, according to the scheme: “Command, Parameters
<CR>”. The terminal settings should be: Baud rate: 115200 bps, Data bits: 8,
Parity: none, Stop bits: 1, Flow control: none.
2. Connecting the unit to a PC and using the WA Manager software. This is the
most convenient way. The Device ID, which is necessary for connecting the
unit to the Sigfox network, is automatically read during downloading the
parameter file to the device. The Device ID is also printed on a label in the
device interior.
