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.

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.

3.4 Battery installation
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’)

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.
