Introduction

The RTCU NX-200 is the most advanced automotive IIoT Gateway product available on the
market today. Based on the successful hardware architecture from the RTCU NX-400, it features an
added range of sophisticated automotive features like a full-motion sensor suite, dual CAN bus
interfaces, Worldwide LTE, and a slick aluminium encapsulation with a clear reference to the
popular RTCU MX2 turbo!

The device is based on the new NX32L (NX32 for Linux) architecture, which embraces many new
technologies and at the same time maintains full backward compatibility, which ensures already
implemented and tested NX32 applications can execute without changes.

The RTCU NX-200 is designed to meet the ever-increasing challenges on security, in that it offers
full TLS on all major protocols and includes a hardened protected execution environment with
dual-boot and automatic fallback and recovery.

The RTCU NX-200 device is an automotive-grade device that is designed from the ground up for
professional M2M / IIoT applications with its strong on-board I/O capabilities and multiple
communication interfaces such as World-wide cellular LTE, WLAN, Bluetooth Classic / Low­Energy, dual CAN bus, Ethernet, dual RS232, RS485, and 1-Wire.

The RTCU NX-200 also sports two USB host port interfaces allowing for the expansion of the
device with accessories such as RFID reader, additional Ethernet port, and additional RS232/RS485
ports

The on-board I/O system can be expanded almost indefinitely and completely transparently by
adding Modbus I/O modules.

The RTCU NX-200 is fully software and hardware compatible with the RTCU MX2 turbo.

The advanced power-management features on the RTCU NX-200 combined with the on-board
high-capacity Li-Ion battery allows the device to stay in a power-saving mode for a longer period
still being connected to the cellular network and capable of waking up on for example cellular
activity, change of digital inputs or a vibration sensor

This manual contains technical documentation on the installation and usage of the RTCU NX-200
device. For detailed information on the programming and software configuration of the product,
please refer to the RTCU IDE documentation.

For detailed information on the powerful RTCU M2M Platform, please refer to the
RTCU M2M Platform datasheet and the RTCU IDE documentation.

Power supply

The RTCU NX-200 device must be supplied with 8..36 VDC from an external DC power source
connected to the 4 pin power connector. Positive power is applied to the SUPP pin, and the ground
is connected to the PGND pin.

The connector has two “SUPP” supply pins as these also supplies power to the digital outputs. If

the total current consumption on the digital outputs exceeds 1.5A, then power must be applied to
both pins. Otherwise, one pin is sufficient.

There are three different labels for the ground connections: Power Ground (PGND), Signal Ground
(SGND) and Analog Ground (AGND). The signal and analog grounds are filtered from the power
ground. Power ground must only be used as a power supply return path. The signal ground is
used as a ground reference for digital I/O’s and serial interfaces, and the analog ground is used as
a low noise analog ground reference for the analog inputs.

The RTCU NX-200 is protected against wrong polarity. If a chassis or system grounds are
connected to either SGND or AGND, a wrong polarity on the supply lines will destroy the internal
GND connection. For the avoidance of such a scenario, a fuse can be installed on the positive
supply.

The RTCU also contains an internal high capacity backup battery that will supply the RTCU, if the
external power supply should fail or be disconnected. By default, the RTCU is powered down
when a power failure occurs. This setting, however, can be changed. Please consult the RTCU IDE
documentation for additional information.

Disabling the external DC power from the application interface and forcing the device to operate
on the internal backup battery is supported. Please consult the RTCU IDE documentation for
additional information.

When the ignition input is activated with a logical high, the RTCU device will wake-up if it was in
power-down mode. The ignition input (digital input 1) is available on the power connector to
minimize the need for connectors in minimal installations, but it is also available on the X3
connector (digital I/O and analog Inputs) - only one should be used at a time.

Digital outputs

The digital outputs control four “high-side” switches. They function like a contact, where one side
is connected to the positive supply of the RTCU unit, and the other is the output. The switches are
protected against short circuit, ESD and electronic kickback from inductive loads such as relays,
etc. The maximum switch-able inductance is 20mH and must not be exceeded.

The digital outputs are supplied through the X1 power connector that also supplies the rest of the
RTCU unit. As this power is also the RTCU NX-200 main power, a power-fail would also affect
the digital outputs.

The RTCU unit offers a very advanced power management that makes it possible to have one or
more outputs enabled while the RTCU is in low power mode. Please consult the RTCU IDE
documentation for additional information.

Please note: Special attention to wiring must be taken; if the total current consumption of the
digital outputs exceeds 1.5A, then PGND must be used as a return path for the output(s).
If the total current consumption of the digital outputs exceeds 5A, the two SUPP pins and PGND
must be used for supply.

Digital Inputs / Ignition Input

The digital inputs are all low pass filtered and transient protected. To activate the inputs, connect a
positive voltage between the input and the GND connector.

Please note: The DIN 1/IGN input is special as it also functions as the ignition input. If the ignition
input is activated with a logically high or low (Wait For Event mode only), when the RTCU is in
low power mode, it will wake-up the unit. A power apply will also wake-up the unit, if it is in
power-down mode or WaitForEvent mode with power Apply and/or ignition selected for wake­up. The ignition is de-bounced with a period between 1-2 ms, when used as a digital input. So, any
logical level applied to this input must be greater than 2 ms to be valid. The DIN 1/IGN input is
available on both the X1 power connector and the X3 connector together with the other digital
inputs – only one should be used at a time.

The power management allows the possibility to configure a wake-up on one or more digital
inputs with individually configured falling- or rising edge detection. Please consult the RTCU IDE
documentation for additional information.

Analog Inputs

The analog inputs are voltage inputs specified with an operating range of 0V to 10V DC. The
conversion resolution is up to 12 bit (0..4095). Please consult the RTCU IDE documentation for
further details.

Flex Inputs

The flex inputs are multi-mode inputs that can be configured to operate as either analog or as
digital inputs. The operating range is from 0V to 30V DC and is configurable as digital inputs with
customized threshold values.

The flex inputs can also be used as digital inputs, either behaving the same way as the normal
digital inputs with the same threshold values or by using different threshold values for more
advanced features.

The same flex input can be used for multiple digital inputs with different settings, e.g., different
threshold values or debounce timing.

Configuring the flex input for band matching allows triggering the digital inputs at specific values,
making it possible to connect circuits that generate different voltages for different states and then
read the state directly.

An example could be using switches and resistors to create an R2R ladder that allows for
connecting multiple switches to a single flex input.

See the RTCU IDE documentation for more details about how to configure the flex inputs as digital
inputs.

The input signal is connected between FLXINx and AGND. AGND must be connected to the
reference of the connected equipment. Please be aware that deviations may occur, as the system is
very noise sensitive. Avoid long unshielded wires, and large fast-changing signals routed parallel

CAN communication port

The RTCU provides the physical layer for the CAN (Controller Area Network) serial
communication interface in accordance with the ISO 11898 standard. The CAN bus is designed for
high-speed (up to 1Mbit) robust communication in especially harsh environments like those found
in the automotive industry.

The CAN interface can be connected to an existing CAN network with a common protocol like the
J1939 standard, to retrieve information for surveillance or information purposes. The interface can
also be used as a robust serial data link with a non-standard protocol. Please consult the RTCU IDE
documentation for more information.

The physical layer consists of a two-wire (CAN-H and CAN-L) differential bus and a signal
ground for reference.

If the RTCU is connected to a “non-existing” network, a 120 ohm resistor must be connected
between CAN-H and CAN-L on each end of the transmission line in order to terminate it and
avoid signal reflections. This resistor can be connected by activating the software jumper in the
user application. Please consult the RTCU IDE document for the software jumper for a detailed
description.

Be aware that connecting the RTCU to a CAN network can be dangerous. If the RTCU is not
configured with the correct network parameters, it will lead to network corruption and may
interfere with other connected equipment on the bus. Especially in vehicles, great precautions
must be observed to prevent communication interruptions.

By default, the write capability on the CAN bus channel 1 is disabled. This can be enabled by the
jumper that is located at the front-side of the device.

By default, the write capability on the CAN bus channel 2 is enabled and it is not possible to
disable

A wide range of software functions is available for easy access to the network. Please consult the
RTCU IDE documentation for further information.

RS485 communication ports (EIA/TIA-485-A compatible)

RS485 is a multi-drop network with a maximum of 32 nodes connected simultaneously to the bus.
The RS485 bus contains an RS485+ ( also known as RS485 A, non-inverting) and an RS485- (also known
as RS485 B, inverting) signal as well as a signal ground which must always be connected to the
common signal ground for all nodes connected to the RS485 bus!

The maximum cable length for the RS485 bus is according to the EIA/TIA-485-A standard (max.
1000m @ <100kbit); this limit is highly influenced by the quality of the cable, signaling rate, noise
etc.

At longer cable lengths, noisy environments, or high communication speeds, it might be necessary
to terminate the transmission line with a 1201 ohm resistor at each end of the transmission line to
terminate it and avoid signal reflections. If the RTCU NX-200 is used as an endpoint node, the
software jumper for both RS485 ports separately can be activated through the user application in
order to terminate the RS485 communication lines with 120Ω.

By default, the RS485 communication lines are not terminated with 120 Ω. Please consult the RTCU
IDE documentation for further information on how to use the software jumpers.

Please note: For best performance, protection and noise immunity shielded cable advised to be
used to connect the device to the RS485 communications bus.

1-Wire bus

The 1-Wire bus is available on the X2 connector. All 1-Wire communication goes through a single
connection, and all 1-Wire devices connected to this connection retrieves its power directly from
the bus (called parasitic power). For this, only two wires are needed – the 1-wire signal and the
ground reference – allowing minimal cable installations.

For 1-Wire ID-Button readers, which include a built-in LED, a dedicated output is available for this
purpose. Please consult the RTCU IDE documentation for further information.

System LED S1 and S2

The RTCU is equipped with two system LED’s, which shows the status and possible errors of the
RTCU device.

The different patterns are listed in the table below. If the color of the system LED S1 is yellow, the
device is actively communicating with the RTCU IDE (or another program, supporting the RTCU
RACP protocol).

The LED S2 is signaling either the cellular module activity or if all other LED’s are off, that the
RTCU is in the “wait for event” low power state.

Switches

DIP-switch

The RTCU NX-200 device contains two dip-switches. The dip switches are located on the front side
of the device for easy user access (see graphical overview).

System switch (RST)

The RTCU NX-200 device contains a combined reset/diagnostic switch. This switch is accessible
from the front of the unit (see graphical overview). It is necessary to use a small thin object with a
diameter of approx. 2 mm, for example, a straightened-out paper clip for this purpose.

By activating the switch shortly, the RTCU device will do a complete reset as if the power was
removed and reapplied.

If the reset switch is held down for approx. 3 seconds1 the device will instead enter recovery mode2
where the application will not be started. In recovery mode, the system will automatically turn on
any communication channel and establish a connection to the RTCU Gateway (if configured).

Pressing reset will also activate the device when in power-down mode. If external power is
removed and the backup battery is disabled, the reset switch can still be used to boot into recovery
mode, as long as there is enough power left on the battery.

5 System LED S2 will flash green three times when this state is entered.

6 System LED S1 will indicates this state by fast blinking green or yellow.

Internal Li-Ion battery

The RTCU contains an internal Li-Ion battery for operation even when the external power is
absent, making it possible to report power loss etc. Please note that when external power is
removed, the device will be powered down by default. This setting can be changed as documented
in the RTCU IDE documentation.

The analog outputs will be disabled when power failure occurs as the internal battery cannot
provide the supply voltage needed.

The battery charging is completely automated and handled internally by the RTCU device –
leaving no need for user interaction. Different kinds of functions (Battery low, Charger enable,
Charging status, etc.) are available to the user application.

The charge current is relatively high, for shorter charge time, as specified in the technical
specification. Make sure both power supply and cables can handle the high current.

The battery will be charged whenever a power fail occurred to establish the capacity, thus making
the battery ready for the next power failure. A maintenance charge will start every 20 days after
the last charge. This is to compensate for the battery self-discharge etc.

By default, the battery cannot be charged above 45C or below 0C. The RTCU offers to charge
down to -10 ˚C using a specialized algorithm to protect the battery.

If the temperature is above 45C the charging will not start and will be postponed until it is below
this threshold.

The temperature has a very strong influence on the battery capacity. At 0C the capacity has
dropped to 60% of the initial capacity, and it falls dramatically at lower temperatures.

The battery cycle (numbers of charges and discharges) also influences the capacity. After 300 cycles
the capacity has dropped to approximately 80% of the initial capacity.

Warning

Misusing the RTCU device may cause the built-in battery security circuit to be damaged.

• Do not place the RTCU device in high-temperature locations such as in direct sunlight or near

engines. Using the RTCU device in this environment may result in loss of battery performance and
a shortened life expectancy.

• Do not expose the device to water, saltwater or allow the battery to get wet.

• Avoid strong impacts and shocks.

For more information regarding the environmental limitations, see “Specifications for RTCU NX-
200” below or consult the RTCU NX-200 datasheet.

To ensure the highest performance and compatibility, it is important to use SD-CARDs that has

been approved and tested by Logic IO.

Commercial grade SD-CARDs can be used in applications where the limited write endurance is
acceptable - for example, if the SD-CARD is often replaced. Commercial grade SD-CARDs should
not be used in applications where a potential failure on the media is considered mission-critical.

For applications that use the SD-CARD media extensively and where failure is critical, it is
recommended to use approved Industrial Grade SD-CARDs.

Logic IO has approved and recommends industrial-grade SD-CARDs from ATP that is available in
capacities from 512 MB to 32 GB.

ATP Industrial Grade SD/SDHC Cards are optimized for demanding industrial applications with
consistent performance in all conditions. ATP uses reliable SLC flash technology with a flash
endurance more than 20 times higher than commercial grade products with MLC flash.

The differences in write endurance between commercial-grade MLC flash and ATP Industrial
grade SLC flash is quite remarkable for write-intensive applications:

Appendix B – Installing the internal SIM-Card

WARNING: Disassembling the device must be performed by a professional personal.

ATTENTION: The device internal electronics are sensitive to Electrostatic Discharge
(ESD) and must be handled only in an ESD safe environment.
Avoid touching the electronics components and parts.

The internal accessible SIM card reader is a hinged reader with a mechanical lock for secure
installation of the SIM card.

To gain access to the internal card reader, the circuit board must be pushed out. This operation is
described in the following steps:

1. Remove the three screws on the backplate.

2. Pull gently and slowly the backplate near the GNSS antenna connector. The circuit board is

fixed inside the encapsulation due to the internal battery holder and may require a small
amount of force. You may push from the front side, through the USB Host port 1 connector;
please do not push hard, nor use any tools that can damage the connector.

3. It's important to pull the circuit board evenly on both sides.

Appendix D - Enabling the CAN bus channel 1 write capability

Connecting the RTCU to a CAN network can be dangerous. If the RTCU is not configured with the
correct network parameters, it can lead to network corruption and may interfere with other
connected equipment on the bus. Especially in vehicles, great precautions must be observed to
prevent interruption of communication.
By default, reading from the CAN bus is enabled and writing to the CAN bus is disabled by a
hardware jumper inside the unit.

Installing this jumper, and thereby enabling the CAN-bus Write capability of the unit, is done on
the sole responsibility of the user. Logic IO can not be held responsible for any problems, or
damage due to the decision to enable the CAN-bus Write capability.

The following steps must be taken to enable the CAN bus Write capability of the unit:

ATTENTION: The device internal electronics are sensitive to Electrostatic Discharge
(ESD) and must be handled only in an ESD safe environment.
Avoid touching the electronics components and parts.

1. Remove the frontplate by removing the three screws.

2. The jumper is located on the bottom side of the circuit board, near the audio jack connector.

3. Insert the jumper. Please pick a suitable jumper, that is not too long to conflict with the

endplate.

4. Place the frontplate, so the connectors fit the openings, then tighten the two screws.

Be careful not to tighten the screws too much, thereby damaging the aluminum.
