2.2 Power Supply Connection
The device is designed to work with 24 V AC/DC separated power supply.
Figure 4. 24 V AC/DC power supply connection
2.2.1 Earth Grounding
Earth grounding protects from electrostatic discharge or other forms of EMI. Connecting the
controller’s ground spade lug to nearby earth ground is possible in hardware versions below
2.1.
2.3 Communication Bus Connection (RS485)
The device is equipped with opto-isolated RS485 base port, which allows connecting the
device to the BMS in order to communicate with other devices in the network. The optional
controller version has an extension as second RS 485 port. All rules are the same as in the
base port. The way of proper bus cable connection is shown in the figure below.

iSMA-B-MAC36NL User Manual
Version 1.4 www.gc5.pl Page 11 / 51
Figure 6. RS485 communication bus connection
2.3.1 RS485 Grounding and Shielding
The device can be exposed to electromagnetic environment. The electromagnetic radiation
can induce electrical noise into both power and signal lines, as well as direct radiation into the
device causing negative effects to the device functioning. Appropriate grounding, shielding
and the other protective steps should be taken at the installation stage to prevent undesirable
effects. The preventions include making control cabinets grounding, cables shield grounding,
using protective elements for electromagnetic switching devices, using correct wiring as well
as appropriate cable types selection and cable cross-sections.
2.3.2 RS485 Network Termination and Biasing
The transmission line often creates communication problems. These problems include
reflections and signal attenuation.
To eliminate the presence of reflections at the ends of the bus cable, it must be terminated at
both ends with a resistor across the line. The resistor value has to be the same as a
characteristic impedance of the bus cable. Both ends must be terminated since the direction
of propagation is bidirectional. In case of an RS485 twisted pair cable, the termination is
typically 120 Ω.
In the iSMA-B-MAC36NL version there is a built-in 3 position Switch on the back side of the
device (access after removing the back cover) which is dedicated to connecting termination

iSMA-B-MAC36NL User Manual
Version 1.4 www.gc5.pl Page 12 / 51
resistor and/or biasing resistors. In the iSMA-B-MAC36NL-RS version 3 position Switch is a
built-in below terminal connector as shown in the figure below on the right side.

When the switch is in the END position it connects the termination resistor 120 Ω and biasing
resistors 680 Ω (pull-down to ground SG and pull-up to +5VDC) to the RS485 bus.
So instead of using additional resistors, the termination and biasing can be easily done by
simple switch activation.
Figure 8. RS485 network termination and biasing

iSMA-B-MAC36NL User Manual
Version 1.4 www.gc5.pl Page 14 / 51
When the switch is in the BIA position it connects the biasing resistors 680 Ω (pull-down to
ground SG and pull-up to +5VDC) to the RS485 bus. The biasing is added to the RS485 bus
in order to reduce communication failures.
WARNING! Only one single device on the network can have biasing resistors connected.
Connecting biasing resistors on two or more devices on the one single RS485 bus will take
the opposite effect –increase the number of communication problems.
Figure 9. RS485 network biasing
2.3.3 M-Bus Connection
M-Bus devices can be connected directly only to the iSMA-B-MAC36NL-M, hardware version
with M-Bus interface (max. 20 devices).

detected automatically and displayed for information in the Products field of the Workbench
platform.
2.5 LED Indicators
The device is equipped with LEDs for quick status checking and diagnostics:
Figure 11. LEDs on the front panel of iSMA-B-MAC36NL.
•The Power LED ON lights up (green) and then turns the power supply on.
•The Communication LED COM1 lights up (orange) for 20 ms in the transmit state for
sending each package through the main RS485 port. As long as the device sends
packages, the Communication LED blinks continuously.
•The Communication LED EXT lights up (orange) for 20 ms in the transmit state for sending
each package through the extension RS485 port. As long as the device sends packages,
the Communication LED blinks continuously.
•The Communication LEDs ETH1 and ETH2 light up (orange) in the transmit or receive state
when sending/receiving each package through the particular Ethernet port. As long as the
device sends/receives packages, the Communication LEDs blink continuously.
•The Universal Inputs LEDs U1-U16 indicate the statuses of the Universal Inputs. When the
LED is ON, the resistance value connected to the input is lower than the switching
threshold value (Dry Contact input is active).
Note: The LED also lights up when the voltage connected to the input has very low potential.
•The Digital Inputs LEDs I1-I4 indicate the statuses of the Digital Inputs. When the LED is
ON, the Input is active (resistance value connected to the input is lower than the switching
threshold value).

iSMA-B-MAC36NL User Manual
Version 1.4 www.gc5.pl Page 16 / 51
•The Analog Outputs LEDs A1-A8 indicate the statuses of the Analog Outputs. When the
LED is ON, the Output voltage or PWM factor is different than 0.
•The Digital Outputs LEDs O1-O8 indicate the statuses of the Digital Outputs. When the LED
is ON, the Outputs is active (closed circuit).
•The Status LED RUN does not light when the power is connected. After Operating System
(Linux) has started up, the LED RUN lights up continuously (green). Next, after the Platform
has started up, the LED RUN also flashes very quickly. If a station exists in a controller,
after the station has been started up and it operates correctly, the LED RUN flashes slowly
(1Hz).
•The Alarm LED Δ (triangle with an exclamation mark) lights up in red color when there is
no SD card inserted or there is a problem with the SD card connection/reading/writing.

3Start-up
3.1 Before the Start
To be able to operate normally the device needs to have the following:
1. SD card (fitted in SD card box)
2. License assigned
The hardware itself is only the base for SD card which consists of all the software parts needed
for hardware management.
The SD card is not assigned to a particular hardware unit. It can be moved to another
hardware. This function allows for easy hardware replacement. Together with the SD card all
the parameters such as Communication Settings, station, Niagara, JVM and Operation
System are moved.
License file provides a limited number of points which can be used to build your application.
Without the license file, user is not allowed to run the station on the device.
3.2 SD Card
Without the microSD card the device cannot operate properly.
MicroSD Card contains all main software parts which are crucial for the device functioning:
1. Linux Operating System
2. Java Virtual Machine
3. Niagara N4

iSMA-B-MAC36NL User Manual
Version 1.4 www.gc5.pl Page 18 / 51
The Card slot is placed on the left side of the device as it is shown in the figure below.
The micro SD card must be inserted into the unit prior to the mounting process. However, it is
possible to move an SD card from one unit to another (microSD Card is not assigned with the
particular hardware iSMA-B-MAC36NL unit). For example, you might want to remove the SD
card from a unit that suffered a hardware failure and use it in a replacement unit.
Prerequisites:
All power to the controller needs to be shut down before inserting/removing the micro SD card;
otherwise equipment damage may occur.
The controller needs to be unmounted from any DIN rail or screw tab mounting, as accessing
the card uses space behind the mounting base.
Discharge any static electricity that you may have accumulated by touching a known, securely
grounded object.
Figure 13. SD Card Mounting

iSMA-B-MAC36NL User Manual
Version 1.4 www.gc5.pl Page 19 / 51
Insert the micro SD card by sliding the card into the card socket, label side down, until the
spring catch engages.
Remove the micro SD card by pushing the card in, until the spring release pushes the card
partially out of the card socket. Grasp the card and pull it completely out of the unit. Store the
micro SD card in a static-free protective case.
3.3 Factory settings
Out of the box, the SD card Image has the factory settings. Whenever the controller is restored
via clean or update distribution file, the default settings are restored. Please refer to the
Controller System Update chapter for more details.
