IMPORTANT
The module should be installed by qualified personnel.
Prior to installation, please read carefully this manual in order to avoid mistakes that can lead
to malfunction or even damage to the equipment.
Disconnect power before making any electrical connections.
Changes, modifications or repairs not authorized by the manufacturer shall void your rights
under the warranty.
The rating plate of the device is located on the enclosure base.
FreeRTOS is used in this device (www.freertos.org).
SATEL aims to continually improve the quality of its products, which may result in changes in
their technical specifications and software. Current information about the changes being
introduced is available on our website.

This manual describes how the ETHM-A module should be installed. For further information
related to the module, including its configuration and operation, please refer to the full version
of the manual, available at www.satel.eu.
1. ETHM-A module 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 EN50131 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).
1.1 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).
1.2 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.
Description of terminals
+12V –power input (12 VDC ±15%).
COM –common ground.
RING, TIP –terminals for connecting the control panel telephone communicator.
S1…S3 –1-Wire bus (1-Wire digital temperature sensors can be connected to the bus):
S1 –common ground,
S2 –data,
S3 –power supply.
I1…I8 –inputs. They can be programmed as digital (NC or NO type) or analog ones.
O1...O4 –programmable OC type outputs (disconnected from common ground / shorted
to common ground).
A RS B –terminals for future use (RS-485).
AC –input for supervision of AC voltage presence or for AC voltage frequency
measurement.

LED A:
ON –power OK,

LED B:
flashing slowly –power OK,
flashing rapidly –data transmission.
RJ-45 connector for Ethernet network. It is provided with two LEDs:
green –ON when the module is connected to the network,
yellow –flashing during data transmission.
USB MINI-B port.
1.3 Connecting the alarm control panel
Connect the control panel telephone communicator to the TIP and RING terminals.
1.4 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. 2). This will
enable the ETHM-A module to supervise the presence of AC voltage or measure its
frequency.

module is powered from SATEL APS-15 / APS-30 power supply unit.
1.5 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).

1.6 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

4 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.
1.7 Connecting the computer to the module
Connect the computer to the module USB MINI-B connector. Having connected the computer
to the module, you can:
configure the module by using the GX Soft program. Download the GX Soft program from
www.satel.eu. Required program version: 2.0 (or newer). See full manual for more
information.
update the module firmware (see full manual).
