2.2.1 Earth Grounding
Earth grounding provides protection from electrostatic discharge or other forms of EMI.
The way to connect the controller’s ground spade lug to a nearby earth ground is shown in the
figure below.
2.3 Communication Bus Connection (RS485)
The device is equipped with opto-isolated RS485 base port, which allows to connect 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.
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.

Version 1.0 www.gc5.pl Page 12 / 40
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 the 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 connect termination
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
Version 1.0 www.gc5.pl Page 14 / 40
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 an
opposite effect –increase the number of the communication problems.

2.4 LED Indicators
The device is equipped with LEDs for quick status checking and diagnostics:
Figure 10 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 packages 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 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).
•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).

iSMA-B-MAC36NL
Version 1.0 www.gc5.pl Page 16 / 40
•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 SD Card connection/reading/writing.
2.5 Mini USB
The mini USB port is dedicated to debugging connection through the console.
You can find a description of how to connect to the system console in Connection to the
console chapter.

2.6 Local I/O
The iSMA-B-MAC36NL has built-in different types of I/O. The specific local I/O set 16x UI, 8x
AO, 4x DI and 8x DO allows to use the device in different applications.
2.6.1 Universal Inputs (16x UI)
All the Universal Inputs have 16-bit ADC, which supports the following types of the input
signals:
•Voltage Input (0 – 10 V DC)
•Current Input (0 – 20 mA)
•Resistive Input (0-1000 kΩ)
•Temperature Input
•Dry Contact Input (Digital Input)

Figure 12 Connection of UI to measure voltage 0-10 V DC.

Version 1.0 www.gc5.pl Page 18 / 40
2.6.1.2 Current Input connection (0 –20 mA)
Current measurement is realized by voltage measurement and 200 Ω resistance.
According to the Ohm’s law the current is directly proportional to the voltage and the
resistance is the constant of proportionality.
𝑰 = 𝑼
𝑹
According to the Ohm’s law equation for 20 mA current with 200 Ω resistance the output
voltage is 4 V.
It means that the 4 V voltage measured on the Universal Input corresponds to 20 mA current.
The result is expressed in millivolts.
Figure 13 Connection of UI to measure current 0-20 mA.
