3. Typical module applications
The extended functionality of ETHM-A module enables it to be used for a variety of
applications. This section presents typical examples of its application. Some of them may be
combined with one other.
3.1 Supervision / control of devices
Fig. 1. Module supervising operation of the devices connected to inputs and controlling
operation of the devices connected to outputs.
Changing the input status / exceeding the defined threshold limit value may result in:
sending event code to the monitoring station (Ethernet reporting);
event notification (messaging) by means of e-mail / push.
The inputs can be bypassed locally (by means of one of the module inputs or in the GX Soft
program) or remotely (in the GX Soft program or the GX Control application).
1-Wire sensors can be bypassed from GX Soft program or GX Control app.
The devices connected to the module outputs can be controlled locally (by means of module
inputs or in the GX Soft program) or remotely (in the GX Soft program or the GX Control
application).
3.2 Simulation of monitoring station
Fig. 2. Module simulating the monitoring station.

6 ETHM-A SATEL
The module can forward the event codes received from the control panel to the monitoring
station by means of Ethernet.
3.3 Work within the Internet of Things (IoT)
Fig. 3. Module working within Internet of Things (IoT).
Using Ethernet (TCP), the module can communicate with devices in the Internet of Things
(IoT). This allows the module to be integrated e.g. with automation systems and
measurement data acquisition systems. The module can send information about the status of
inputs / outputs as well as data from analog inputs and 1-Wire bus to the IoT devices.
In response, the module can receive commands to bypass / unbypass the inputs as well as
to activate / deactivate the outputs of the module.

5. Installation
The device is designed to be used only in the local area networks (LAN). It must
not be connected directly to the public computer network (MAN, WAN).
For establishing connection with public networks, use a router or xDSL modem.
Disconnect power before making any electrical connections.
The ETHM-A module should be installed indoors, in spaces with normal air humidity.
If the module is to comply with requirements of the EN 50131 standard for Grade 2,
it must be installed in an additional enclosure that will enable it to meet requirements
of the tamper standards (e.g. in the SATEL OPU-3 or OPU-4 enclosure).
5.1 Preparing the cabling
To make electric connections between the module and other devices, use an unshielded
non-twisted cable. Do not lay the cables in immediate vicinity of the low-voltage electrical
network wires, especially those used for supplying the high-power equipment (such as
electric motors).
Connect the module to the Ethernet using a 100Base-TX standard compliant cable (identical
to that used for connecting computers to the network).
5.2 Installation of the module
The module enclosure base makes it possible to secure the module to the mounting surface
by using e.g. a cable tie or angle hooks.
5.3 Connecting the alarm control panel
Connect the control panel telephone communicator to the TIP and RING terminals.
5.4 Connecting the devices to the inputs and outputs
1. Connect the devices whose operation is to be monitored by the module to the input
terminals.
2. Connect the devices which are to be controlled by the module to the output terminals.
3. If the module is to be powered from the SATEL APS-15 or APS-30 power supply unit,
you can connect to the AC input terminal the wire from the secondary winding of the
transformer which supplies the AC voltage to the power supply unit (fig. 6). This will
enable the ETHM-A module to supervise the presence of AC voltage or measure its
frequency.

SATEL ETHM-A 9
Fig. 6. Example of connecting supply and monitoring AC voltage presence / frequency if the
module is powered from SATEL APS-15 / APS-30 power supply unit.
5.5 Connecting the digital temperature sensors (1-Wire)
You can connect up to 8 digital temperature sensors to the 1-Wire bus. The length of wires
should not exceed 30 meters. If several sensors are to be connected to the bus, it is
recommended that you use the distribution box module (MZ-2 or MZ-3).
SATEL offers the DS-T1 and DS-T2 waterproof temperature sensors. The DS-T1 sensors
measure temperatures ranging from -35°C to 60°C, while the DS-T2 –from -40°C to 110°C.
They are suitable for indoors or outdoors mounting. The DS-T1 sensors are designed for
surface mounting. They can be secured to the mounting surface with adhesives or screws.
The DS-T2 sensors are designed for flush mounting (they are 6 mm in diameter). The DS-T1
/ DS-T2 sensor wires are to be connected to the bus terminals in the following manner:
black wire –terminal S1 (common ground),
green wire –terminal S2 (data),
white wire –terminal S3 (power).
Fig. 7. Dimensions of DS-T1 temperature sensor enclosure.
5.6 Connecting the power supply and starting the module
The module may be powered from the control panel, from an expander with power supply,
or from a power supply unit. SATEL offers power supplies (e.g. APS-412), which can be
connected to the APS connector on the electronics board.
1. Depending on the selected method of module powering, connect the power supply unit
to the APS connector or connect the power leads to the +12V and COM terminals

10 ETHM-A SATEL
(use flexible conductors with a cross-section of 0.5-0.75 mm2, or rigid conductors with
a cross-section of 1-2.5 mm2).
Never connect power supply to APS connector and terminals at the same time.
2. Power up the module. The module will start up.
6. Configuring
You can configure the module by using a computer with GX Soft program installed.
Download the GX Soft program from www.satel.eu.
