Introduction
The Nanonis Real-Time Controller RC5 is the central data processing unit of a Nanonis System. The RC5 provides
connectivity to other instruments in the Nanonis family, FPGA processing for high-speed calculations, CPU power
for slower time-deterministic processes, and a TCP/IP connection to the host computer running the Nanonis
software.
The RC5 is equipped with six device ports for connecting the Nanonis SC5 or OC4. Up to three instruments of each
type can be connected, with a maximum total of four instruments being supported in the software. The
configurations are shown in the table below.
No SC5 One SC5 Two SC5s Three SC5s
No OC4
One OC4
Two OC4s ()
Three OC4s () ()
The RC5 also provides four digital ports (DIO ports) with eight digital lines each, for digital control and readout of
other Nanonis or third-party instruments. All four ports are bidirectional and allow data rates of up to 500 kHz. For
faster data rates, four additional high speed digital inputs and outputs can be used e.g. for counting purposes (inputs),
or fast pulse generation (outputs). These lines allow data rates of up to 200 MHz.
Note: Under Version 4.5 of the Nanonis software, only two digital ports can be used, and the high speed digital
outputs are disabled.
The RC5 allows for a flexible clock management, making it possible to change or upgrade the clock source
depending on experimental requirements. The clock source can be either the low phase-noise internal clock, an
optional oven-controlled crystal oscillator (OCXO) which can be fitted to the RC5, the OCXO of a Nanonis OC4, or
an external clock source. The clock source is chosen automatically based on a priority list.
The RC5 is connected to the host computer running the control software using a single Ethernet cable. No other
connections are required for operation and installation of software and operating system upgrades.

The real-time system unit is a NI PXIe-8840 (RC5 serial number 17517 and higher) or NI PXIe-8115 embedded
controller. It is based around an Intel Core i5-4400E processor running at 2.7 GHz (3.3 GHz in turbo mode) with 4
GB of RAM (NI PXIe-8840) or Intel Core i5-2510E processor running at 2.5 GHz (3.1 GHz in turbo mode) with 2
GB of RAM (NI PXIe-8115). It provides processing power for all time-critical loops, scan and sweep generation,
and for data acquisition. It also takes care of the TCP/IP communication with the host computer over its ethernet
connection. The complete real-time unit can be easily removed from the RC5, if necessary. For status information, a
computer screen can be connected to one of the two DisplayPort connectors.
The FPGA card is a NI PXIe-7965R FlexRIO card, connected to the real-time unit over a PXIe-bus. The Virtex-5
SX95T FPGA offers high processing power and speed for all fast data processing tasks, including PLLs, lock-in
amplifiers, digital filters, oversampling, PI controllers, and hrDAC™ modulation. The FPGA is clocked through the
signal and clock distribution unit.
The signal and clock distribution unit is connected over a 200 MHz data bus to the FPGA, and provides connectivity
to the measurement instruments of the Nanonis range. It also addresses the four digital ports (DIO ports, 500 kHz
maximum frequency), the eight high speed digital ports (200 MHz maximum frequency), and manages the clock
sources. The optional OCXO clock is also plugged to the electronic board of the signal and clock distribution unit.

Setup
To properly set up the instrument, a square space of at least 40 cm × 50 cm × 25 cm (W × D × H) is required.
Additional Nanonis instruments require an additional height of 10 cm for each instrument. The RC5 weighs
approximately 7.8 kg, and stability of its supporting table must be guaranteed. It must be possible to access the
hardware from the front and the rear in order to connect all necessary cables. The space has to be dry and kept within
the specified temperature range.
Note: Make sure that the power cord is accessible at all times. It must be possible to disconnect the
power cord immediately in case of emergency.
The RC5 is actively cooled, and the air intake is placed at the bottom of the instrument. The four plastic feet
supporting the instrument must not be removed, and no items should be placed between the supporting table and the
bottom of the instrument.
The RC5 requires one power socket (120 VA typical, 200 VA max at 100-230 V ±10%, 50/60 Hz ±5%) with proper
grounding. A complete Nanonis SPM Control System can require up to eight power sockets, with a total power
consumption of about 600 VA maximum.
Note: The power cord must be connected to a properly wired and earthed socket.
Note:
conforming to IEC60320.
Note: Make sure that the air intake at
RC5 might exceed its maximum operating temperature and shut down.
Connection to SC5
Only one single cable, supplied with the SC5, is needed as a connection between the SC5 and the real-time controller
RC5. The DEVICE RDIO cable is labelled as SHC68 – 68 – RDIO. Place the SC5 and RC5 at the desired location,
and make sure that the space requirements listed in the previous section are fulfilled.

DIO ports
The four DIO ports (DIO: Digital Input Output) of the RC5 are independent bidirectional digital interfaces with eight
signal lines each with a TTL signal level of 3.3 V. Each port uses a D-sub9 female connector, with one pin used for
digital ground. The maximum current in output mode is 25 mA for each pin, and the maximum bandwidth of the
signal lines is 500 kHz. The ports can therefore also be used for controlling external instruments over a Serial
Peripheral Interface bus (SPI). The DIO ports should not be used for pulse counting purposes. The High Speed
Digital Inputs should be used instead.
Nanonis instruments requiring control over a digital interface like the Nanonis PMD4 and PD5 have to be connected
to these ports.
DIO ports connection
A connection to the DIO ports has to be made using cables fitted with a D-sub9 male connector. A conventional D-
sub9 1:1 cable can be used for this purpose. All Nanonis instruments requiring a connection to a DIO port (Nanonis
PMD4, PD5, HVA4, as well as all adaptation kits) are delivered with a suitable double-shielded cable. For these
instruments, do not replace the double-shielded cable with a conventional cable.
For all Nanonis products requiring a connection to a DIO port, as well as for many third-party instruments, the DIO
port to be used is specified within the license file of the Nanonis system. Please make sure to connect the instrument
to the correct DIO port. The picture below shows the connection to DIO port A.
Figure 15: Connection of a digital cable to a DIO port of the RC5 (DIO port A shown).

DIO ports schematic and connector pin layout
The DIO ports are connected to the signal distribution unit over a general purpose input output (GPIO) expander,
which provides electrical protection and isolation. The ground line of the DIO ports is connected to digital ground of
the RC5. All four ports use D-sub9 female connectors. The following picture shows the schematic of one of the
ports. All four ports are identical.
Figure 16: DIO ports schematic. All four DIO ports have the same electrical configuration.
For the pin assignment of the DIO ports, see the figure and table below.

High Speed Digital Inputs
The four high speed digital inputs of the RC5 offer a high-speed input interface typically used for pulse-counting
purposes. In contrast to the DIO ports, which are designed for frequencies up to 500 kHz, the high speed digital
inputs can accept input signals with frequencies up to 200 MHz. Each input uses a SMB male connector, with the
shield connected to digital ground.
High speed digital inputs connection
Connection to the high speed digital inputs has to be made using a cable fitted with female SMB connectors. The
connectors can be straight or angled. The connection of SMB cables is shown in the picture below.
Figure 18: Connection of SMB cables to the high speed digital inputs.
High speed digital inputs schematic
The signal applied to the High Speed Digital Inputs is converted to a LVDS signal after passing protection and level
matching circuits. The shield of the SMB connector is connected to digital ground of the RC5. All four inputs use
SMB male connectors. The following picture shows the schematic of the four high speed digital inputs.

High Speed Digital Outputs
The four High Speed Digital Outputs of the RC5 offer a high-speed output interface typically used for fast pulse-
generation purposes. As for the High Speed Digital Inputs, in contrast to the DIO ports, which are designed for
frequencies up to 500 kHz, the high speed digital outputs can generate signals with frequencies up to 200 MHz. Each
output uses a SMB male connector, with the shield connected to digital ground.

High speed digital outputs schematic
The high speed digital outputs are driven by high speed signal drivers with paralleled outputs, which can drive long
cables. The shield of the SMB connector is connected to digital ground of the RC5. All four outputs use SMB male
connectors. The following picture shows the schematic of the four high speed digital outputs.

RC5 Real-Time Controller Clock

Clock
Clocking options
The RC5 can accept four different clock sources, which are selected automatically when the RC5 is powered on
based on a priority list. The clock source can be either the low phase-noise clock of the FPGA, an optional oven-
controlled crystal oscillator (OCXO) which can be fitted to the RC5, the OCXO of a Nanonis OC4, or an external
clock 10 MHz source. Only one clock source will be used, while clock sources at a lower priority will be ignored.
The clock signal is used as a clock reference for all instruments connected to the RC5. The clock signal from the
selected clock source is then available at the CLOCK OUT connector (13).
The clock source is selected during power-up of the RC5 according to the following priority list:
• First priority: External 10 MHz clock source, e.g. atomic clock. As soon as a valid clock signal is applied to
the CLOCK IN connector (11) it is used as a clock reference for the RC5 and all instruments connected to it.
The internal optional OCXO, the OCXO clock signal of the attached OC4, as well as the internal FPGA clock
signals are ignored.
• Second priority: Optional internal OCXO. If the optional OCXO is installed, and no valid clock signal is
applied to the CLOCK IN connector (11), its signal is used as a clock reference for the RC5 and all instruments
connected to it. The OCXO clock signal of the attached OC4, as well as the internal FPGA clock signals are
ignored.
• Third priority: OCXO of a Nanonis OC4. If a Nanonis OC4 is connected to the RC5, its clock signal is used
as a clock reference for the RC5 and all instruments connected to it, if no valid clock signal is applied to the
CLOCK IN connector (11), and the optional internal OCXO is not installed. The internal FPGA clock signal is
ignored. The OC4 providing the clock source must be connected to the OC 01 port.
• Fourth priority: Internal FPGA clock. If none of the other clock sources are available, the internal FPGA
clock is used as a clock reference for the RC5 and all instruments connected to it.
Note: Before connecting an external clock source, make sure that its frequency is 10 MHz and that the
signal level is 3.3 V.
The Clock Source LEDs (12) indicate which clock source is active, and therefore which clock source is available at
the CLOCK OUT connector (13). Only one source can be active at one time, therefore only one LED can be lit at
one time. The picture below shows the situation for an active external clock source.
If an external clock source is connected to the CLOCK IN connector but the EXT LED does not light up, then the
external clock signal does not comply with the frequency and amplitude requirements. Please check the Clock ports
specifications section and make sure that the external clock source provides a compatible clock signal.

•

Figure 22: Function of the Clock Source LEDs: In this case, an external clock source is connected to the CLOCK IN
connector. The EXT LED lights up, indicating that the external clock is chosen as reference clock, and that the CLOCK
OUT connector outputs this clock signal.
Clock ports connection
Connection to the Clock ports (11,13) has to be made using a cable fitted with female SMB connectors. The
connectors can be straight or angled. An example for the connection of an external clock source is shown in the
figure above.
A connection to the clock ports is required only if:
• The clock reference of external instruments has to be synchronized with the clock reference of the RC5. In this
case the signal available on the CLOCK OUT connector (13) has to be connected to the reference clock input of
the external instrument.
• The RC5 and all instruments connected to it have to be synchronized with an external clock reference, e.g. an
atomic clock. In this case the external reference should be connected to the CLOCK IN connector (11).

Optional OCXO clock mounting instructions
The optional OCXO is user-installable and can also be fitted to the RC5 after purchase of the instrument. The
oscillator is delivered without other components, and needs to be inserted into a dedicated socket on the signal
distribution board inside the RC5.
In order to install the OCXO, the RC5 needs to be opened. The following tools are required:
• 3 mm hex screwdriver
Note: Installation of the optional OCXO requires the RC5 to be opened, and requires the placement of
a relatively small object close to electronic components sensitive to electrostatic discharge (ESD).
Make sure to follow all directives for handling ESD sensitive components before proceeding. A wrist
strap connected to ground must be worn when performing the modification. Please send the RC5 back
to SPECS for the modification if there is any doubt about how the modification should be performed.
Before proceeding with the installation of the optional OCXO, please make sure that:
• All instruments (SC5s and OC4s) are disconnected from the RC5
• All DIO, High Speed Digital Input and Output, as well as Clock input and Output cables are disconnected from
the RC5
• The RC5 is disconnected from the mains.
Once the above criteria are fulfilled, put the RC5 on a stable and sufficiently large surface. Remove the four plastic
caps covering the screws which hold the top cover of the instrument as shown in the figure below, and remove the
screws by turning them CCW using the 3 mm hex screwdriver. Make sure not to lose the lock washers placed below
the screws. The top cover can now be carefully lifted, and should be put on the side of the instrument. Note that there
is a grounding wire connecting the top cover with the rest of the instrument. This prevents the top cover being
completely separated from the unit but allows the top cover to be lifted by approx. 10 cm to facilitate removal.
Warning: Lethal voltages are present inside the RC5.
Note: Before installing the optional OCXO, make sure that the RC5 is disconnected from the mains.
Caution: The inner frame of the RC5 and the printed circuit boards have sharp edges. Proceed with
care in order to avoid injury.

Note: Make sure to install the optional OCXO as shown in the picture above. Installing it in the wrong
orientation might lead to damage of the OCXO and malfunctioning of the RC5.
Once the optional OCXO is correctly installed, the RC5 will use it as its clock source, as long as no external source
is connected to the CLOCK IN connector (11).
Warning: Avoid any physical contact with or modification of the areas of the instrument marked by
the high voltage warning sign, as this might impair the safety of the instrument.
Note: Make sure that the grounding wire is still firmly connected to the top cover and to rear panel
before closing the instrument. A loose grounding wire will impair safety of the instrument. Also make

Upgrades and replacements
Firmware update
The RC5 is delivered with a firmware which defines all functionality and enables connection with all instruments
described in this manual. Changes to these parameters might require a firmware update.
Note:
without being advised to do so by SPECS voids the RC5 warranty.
Note: Firmware upgrades should not be confused with real-time software upgrades. The latter is performed
automatically from the Nanonis software when required. A firmware upgrade is only necessary when hardware-
related changes require new or modified functions of the signal and clock distribution unit.
Updating the firmware is a simple procedure, which only requires replacing a small printed circuit board (PCB)
inside the RC5. There is no software operation required, and the RC5 does not need to be connected to the host PC.
The board is shipped by postal mail if required. Please ship the old firmware PCB back to SPECS once the new one
has been installed.
In order to replace the firmware PCB, the RC5 needs to be opened. The following tools are required:
• 3 mm hex screwdriver
Note:
relatively small object close to electronic components sensitive to electrostatic discharge (ESD). Make
sure to follow all directives for handling ESD sensitive components before proceeding. A wrist strap
SPECS for the replacement if there is any doubt about how the modification should be done.
Before proceeding with the replacement of the firmware PCB, please make sure that:
• All instruments (SC5s and OC4s) are disconnected from the RC5
• All DIO, High Speed Digital Input and Output, as well as Clock input and Output cables are disconnected from
the RC5
• The RC5 is disconnected from the mains.

Figure 28: Internal view of the RC5. The location of the firmware PCB is indicated by the arrow.
In order to remove the firmware PCB, the board needs to be removed from its sockets by pulling to the right when
the RC5 is oriented as shown in the picture above. The new firmware PCB is inserted by pushing it into the socket
left empty after removing the old one. Removing the firmware PCB might require some force to be applied. Make
sure to keep the main printed circuit board (onto which the firmware PCB is plugged) in place when removing the
firmware PCB by holding it tightly. Do not use pliers for this purpose, as the board could be damaged.
Warning: Avoid any physical contact with or modification of the areas of the instrument marked by
the high voltage warning sign, as this might impair the safety of the instrument.
Note: Make sure that the grounding wire is still firmly connected to the top cover and to rear panel
before closing the instrument. A loose grounding wire will impair safety of the instrument. Also make
sure that no firmware board, screws, tools, or other objects have been dropped or forgotten inside the
instrument. Any object left inside the instrument might impair its safety.
Real-time unit replacement
A replacement of the real-time unit is necessary only in the following cases:
• Malfunction of the unit (see the troubleshooting section for details).
• Increased CPU-load from future revisions of the software requires more CPU processing power, which might be
available with future models of the real-time unit.
• Any other reason for which more CPU processing power than available with the originally delivered real-time
unit might be necessary.
RC5 Real-Time Controller Upgrades and replacements

Note: Please contact SPECS before replacing the real-time unit, if not instructed to do so by SPECS.
Not all PXIe real-
replacement of the real-time unit is done at own risk and voids the RC5 warranty.
Note: By replacing the real-
software license files are therefore not valid anymore, and the control software will not start with the
replacement real-time unit. Please contact SPECS in order to obtain a new license file, and provide the
network adapter MAC address of the new real-time unit.
In order to replace the real-time unit, loosen the four screws marked by the arrows in the figure below. Then, push
down the the lever at the lower right, and pull-out the complete RT-unit from the RC5 enclosure.
Figure 29: Removal of the real-time-unit: After loosening the four screws marked by the arrows, the lever at the lower
right can be pushed down, and the RT-unit pulled out of the RC5 enclosure.
The new real-time unit is inserted by repeating the above procedure in the inverse order. Make sure to carefully align
the real-time unit with the guiding rails inside the RC5, or the unit cannot be inserted corretly into its slot.

FPGA card replacement
A replacement of the FPGA card is necessary only in the following cases:
• Malfunction of the FPGA card.
• Future software revisions require the change of the FPGA card. Users who might require a change of the card
will be contacted by SPECS.
Warning:
recommends as a replacement are compatible with the Nanonis software. Other PXIe FPGA cards will
not work. Any unsolicited replacement of the FPGA card voids the RC5 warranty.
Caution:
damaged if not extracted with great care. Please send the RC5 back to SPECS for the replacement if
there is any doubt about how the modification should be done.
In order to replace the FPGA card, loosen the two screws marked by the arrows in the leftmost figure below. Then,
remove the metallic cover in order to reveal the connector to the FPGA card as shown in the center. Very carefully
extract the connector, making sure not to apply any force on the flexible flat-cable, and place it on the right of the
FPGA card slot, so that the card can be extracted. In order to extract the FPGA card, loosen the two screws marked
by arrows in the rightmost figure below, and pull the FPGA card out of the RC5 enclosure.
Figure 30: Removal of the FPGA card. Left: after loosening the two screws marked by the arrows, the metallic cover can
be removed. Center: The FPGA connector can be extracted by pulling on both the upper and lower edges of the green
printed circuit board, as marked by the arrows. Care should be taken not to pull on the flexible flat-cable at the right of
the connector. The connector can be placed at the right, in order to allow the FPGA card to be taken out. Right: The two
screws marked by the arrow need to be untightened, then the FPGA card can be removed by pulling on the screws, which
are anchored to the card.
The new FPGA card is inserted by repeating the above procedure in the inverse order. Make sure to carefully align
the FPGA card with the guiding rails inside the RC5, and make sure to insert the connector perpendicularly to the
rear panel, without applying any lateral forces.

This chapter describes how the RC5 is connected to and used with a typical Nanonis SPM Control System or
Nanonis Tramea™ configuration, and how the host computer has to be configured. Please make sure that you have
read and understood the sections above before proceeding. All safety warnings are also valid for this section. For
more information about the other instruments shown in the following paragraphs, please refer to the corresponding
user manuals.
SPM Control System: Connections on the rear side of
the instruments
In a typical SPM controller configuration, the following instruments are connected to the RC5:
• Nanonis SC5 and OC4. Connected to the Device Connectors (7, 8).
• Nanonis HVA4, PMD4, PD5, all Nanonis adaptation kits, as well as third-party instruments e.g.
preamplifiers or piezo motor drivers. Connected to the DIO ports (9).
• Host PC. Connected to the Ethernet port (5).
• Additional instruments, clock source. Connected to the High Speed Digital Inputs and Outputs (10, 14), or the
clock ports (11, 13).
The following picture shows a Nanonis SPM control system with two SC5s, two OC4s, one HVA4, and one PMD4a.
Cables other than those connected or related to the RC5 have been omitted. This is a rather complex configuration.
The simplest configuration is the Nanonis SPM Base Package, which includes the RC5 and one SC5.

Software Installation Guide
Host computer requirements
The software running on the host computer is the control and visualization interface of a Nanonis system. The host
computer must therefore be able to handle and visualize all data transferred to/from the Nanonis system, translating
into the following basic requirements:
• There should be sufficient screen space for the software modules and for data visualization. The use of two
screens is highly recommended.
• CPU power should be sufficient for handling data transfers, processing data, and allowing a smooth user
interface operation.
• There should be sufficient disk space for saving acquired data.
All real-time data processing is done on the RC5 CPU, meaning that it is not necessary to use the fastest computer
hardware available. However, using obsolete hardware might result in poor user interface performance, TCP
timeouts, or data losses.
The requirements for the host PC hardware are listed in the table below.

Note: Data streaming to disk into a database requires relatively high data transfer speeds. If this option is used, it is
recommended to use a dedicated hard drive for data storage (7200 rpm with large cache or SSD) and 16 GB RAM or
more.
Note: The number of software installations is not limited, meaning that the software can be installed in parallel on
different computers. However, only one software instance can connect to the RC5 at a time. If there are multiple
RC5 in use, the license file determines to which of the instruments the software will connect.
Note: The software runs under both 32-bit and 64-bit Windows operating systems. 64-bit operating systems are
recommended, since the software can allocate 2 GB of non-fragmented memory if sufficient RAM is installed (4 GB
or more).

Note: A Laptop can be used for running the control software. However, due to limited screen resolution and physical
screen size only a limited number of software modules can be visible at the same time, and the workflow will be
considerably impaired.
Note: If an internet connection is necessary, two network adapters must be installed in the host computer, one for the
internet connection, and one for the connection to the RC5.
Host computer network configuration
This section describes how to configure the network adapter of the host computer. It is necessary to be logged on
with administrator rights, or at least to have a valid administrator password.
Configure the Network adapter of the host computer (the one connected to the RC5) using the following settings:
IP address: 192.168.236.X
Subnet mask: 255.255.255.0
With X being 1-99 and 111-255. Do not use IP addresses between 192.168.236.100 and 192.168.236.110, since
these IP addresses are reserved for the RC5. Do not use IP addresses already in use by other instruments, since this
will lead to an IP address conflict. In case the IP address of the RC5 needs to be changed (e.g. if the second network
adapter is in the same subnet), please contact SPECS. The following sections explain in detail the configuration for
each operating system. Please note that the appearance of dialog windows might be slightly different than shown in
the pictures below. The instructions refer to the Nanonis SPM Control System software, but the same procedures
apply also to the Nanonis Tramea™ software.

Note: As an alternative the firewall for the network adapter used by the Nanonis System can be disabled.
Nanonis software installation
Installation of the Nanonis software requires two files:
• Nanonis SPM Controller Installer V5 RXXXX or Nanonis Tramea Installer V5 RXXXX
• Nanonis license file
The Installer file has to be downloaded from the SPECS extranet website:
http://www.specs-zurich.com/en/extranetlogin.html
under the Software V5 SPM or Software V5 QT tab. The login credentials are provided by SPECS, and sent by email
after purchasing a Nanonis system.
The license file is also provided by SPECS. Make sure to have both files ready before starting the installation of the
Nanonis software.
Note: The license file determines which modules of the Nanonis software will be available once the software is
installed.
Note: The installer for Nanonis Tramea™ software found in the Software V5 QT tab does not contain any SPM
functionality. Therefore it is not possible to start the Nanonis Tramea™ software with a license file intended for a
Nanonis SPM Control System, or a Nanonis OC4.5-S. The installer for the Nanonis SPM Control System found in
the Software V5 SPM tab, on the other hand, contains both functionalities, meaning that it is possible to start the
Nanonis SPM Control System software with a Nanonis Tramea™ license file. Only quantum transport functionality
will be enabled in that case.
Note: The installation procedure described below is valid for both a first installation of the software, as well as for
an upgrade to a higher release.
Note: The appearance of dialog windows might be slightly different to those shown in the pictures below.

For starting the installation process, double-click on the Nanonis SPM Controller Installer V5 RXXXX or Nanonis
Tramea Installer V5 RXXXX.exe file. The following message will appear:
Press OK to start the installation. After the installer has initialized, the following dialog window will appear:
If different installation directories compared to the ones shown are preferred, indicate a different directory in the
corresponding field. Otherwise press Next >>.
Read the license agreement and select I accept the License Agreement, then click Next >>. The following window
will appear. Depending on the installation type (first installation or upgrade), a different summary will be displayed.
The following picture is for an upgrade installation.

Press Next >>, and the installation will start. Once the installation is finished, the following dialog window will
appear:
Press Next >> to finish the installation.
License files
Each RC5 is delivered with a license file. The license file is usually sent by email, together with the login credentials
to the extranet website http://www.specs-zurich.com/en/extranetlogin.html, and is required for the correct
functioning of the Nanonis hardware and software. The main functions of the license file are:
• Ensure that the hardware is configured properly, according to the system configuration
• Manage the software modules loaded when starting the Nanonis software
The license file is bound to the MAC address of the network adapter of the RC5, therefore each license file is
specific to a given RC5, and can’t be used with a different one. The license files are protected, meaning that by
changing entries, the license files become unusable.
Always keep the license file at a known location so it can be retrieved quickly. When contacting SPECS by email,
please always send the license file since this can contribute to speeding up the troubleshooting processes or facilitate
the addition of hardware and software modules.
Note that the license file needs to be changed if the real-time unit is replaced.

First time startup
In order to start the Nanonis software, double-click on the Nanonis software icon, or select the Nanonis software
from the Start Menu. The following startup screen appears:
Click on the “No license file found!” drop-down list and select “Browse…”. A dialog window appears, asking to
specify the license file to be used and its location. Select the correct license file (see the next section for details) and
click “OK”. Another dialog will appear, asking if the file should be copied into a directory where the software can
find it automatically, see below.
It is recommended to click “Yes”, since the license file will then be automatically selected at the next start of the
software. Note that it is possible to copy multiple license files to the Application Data directory. The files can then
be accessed directly from the software startup screen shown above, by clicking on the “Available license files” drop-
down list.
After clicking “Yes” the license file appears in the “Available license files” drop-down list, as shown below.
RC5 Real-Time Controller Software Installation Guide
•
60
All three indicators next to the License File, Expiration Date, and software version should be green to indicate no
errors occurred.
Note that the file can be saved to a different location by clicking on the save icon, or can be deleted from the list by
clicking on the trash icon. The Information icon provides information on the file when hovering the mouse over it.
In order to start the software for normal operation, click on the “Start” button.
Note: At this point a Windows Firewall warning might pop up, informing that the Firewall has blocked some
features of the program. Depending on the operating system, click on “Unblock” or “Allow access” in order to
proceed. This requires administrator privileges. If a different firewall is used, make sure that also that firewall does
not prevent the Nanonis software from running. Antivirus software might also interfere with the startup process of
the Nanonis software. Please make sure that all antivirus software is deactivated at the first start of the Nanonis
software. The software then needs to be configured in such a way, that the Nanonis software is not recognized as a
threat to the computer.
After clicking on the “Start” button, the software will load the modules specified by the license file. However, if the
real-time software is outdated, it might be necessary to update it by following the on-screen instructions explained in
the following section. After that, the following information appears:
Read the text, and if necessary click on “Refer to the online help for more information” in order to access the online
help (does not require an internet connection). Then click on “OK”. In the next dialog window, browse for a
directory to be used as a session directory, then click on “select current directory” at the bottom right of the window.
Note that it is not possible to select “cancel”.
The software is then ready to use.
RC5 Real-Time Controller Software Installation Guide
•
61
Note: This procedure is necessary only during first time startup of the software or when using a new license file.
Otherwise the software automatically selects the last used session directory.
If the software should not start as described above, please refer to the Troubleshooting section.
There are three other options available in the startup screen: Cancel, hrDAC tuning, and Demo.
Cancel closes the startup screen without starting the software.
hrDAC tuning starts the hrDAC™ calibration procedure. Note that during calibration the analog outputs are
internally connected to the analog inputs. This means that output and input connectors will be electrically floating.
For more information about hrDAC™ and the calibration procedure, please refer to the SC5 user manual.
Demo starts the software in simulation mode. This means that the software will not connect to the hardware, but will
only start the host application. The simulation mode can be used for familiarization with the software without the
risk of damaging samples, or for testing and debugging measurement routines written in the Programming Interface.
Only the modules licensed in the license file will be loaded, and a license file is necessary for starting the software in
simulation mode. It is not necessary to have the hardware connected to the host computer.
Real-time software update
The Nanonis software running on the host computer requires a specific release of the real-time software installed on
the RC5. If the latter is older than the required release, a real-time software update is necessary. This is the case
when:
• The Nanonis software has been updated between testing of the RC5 at SPECS and delivery of the instrument
• A newer release of the Nanonis software has been downloaded and installed
If the update is necessary, a dialog window appears automatically after pressing the “Start” button in the startup
screen:
Press “Install new” in order to install an updated release of the real-time software. The following information
window is displayed:
RC5 Real-Time Controller Software Installation Guide
•
62
Click “Next” in order to start the installation. The following two progress windows are displayed:

Troubleshooting
Network and software issues
SYMPTOM: The instrument turns on, but does not respond when starting the software. There is no
indication of faults. The following window appears after starting the software.
Figure 34: This error window appears if no communication between the RC5 and the host computer is possible.
REASON: The real-time controller has not finished booting.
SOLUTION: Wait about 20 seconds and try again. It takes about 30 seconds for the RC5 to finish its boot
process.
REASON: Missing Ethernet cable. In this case there is no entry in the “Available RT-Controllers” field.
SOLUTION: Make sure that an Ethernet cable is connected to both the correct Ethernet connector (5) of the
RC5, and the correctly configured Ethernet port of the host computer.
REASON: Wrong Ethernet cable. In this case there might be no entry in the “Available RT-Controllers” field.
SOLUTION: Make sure that the RC5 is connected to the host computer with a crossed Ethernet cable. A crossed
cable is not necessary if the RC5 is connected to the host computer over a switch, hub, or router.
REASON: The RC5 is connected to the host computer over a router with incorrect configuration. In this case
there is no entry in the “Available RT-Controllers” field.
SOLUTION: Make sure that the router is not acting as a DHCP server. The RC5 has a fixed IP address. Also
make sure that all devices connected to the router have IP addresses in the range 192.168.236.X,
with X being 1-99 or 111-255. The IP addresses from 192.168.236.100 to 192.168.236.110 should
not be used. Please contact SPECS if the IP address of the RC5 needs to be changed.
REASON: Firewall or antivirus software is blocking the communication between RC5 and host computer.
SOLUTION: Disable the Windows firewall, or any other active firewall. If the RC5 is connected directly to the
host computer, a firewall is not necessary. Disable any active antivirus software installed on the
host computer. If this solves the issue, enable the antivirus software, but make sure to configure it
so that the communication is not blocked. Note that system dialog windows requesting an
authorization for connecting to the RC5 or for a firewall exception might be displayed behind
another window. Please make sure that no authorization request is pending.
RC5 Real-Time Controller Troubleshooting
•
65
NOTE: Connection issues related to firewalls, or operating system TCP/IP issues can be solved by
entering the IP address of the RC5 (192.168.236.100, if it has not been previously changed
from the default value, otherwise the changed IP address) in the “check this IP address”
field, and then click “Connect”. If a connection is still not possible, please check all possible
reasons listed here.
REASON: No software or corrupted software installed on real-time controller. A dialog window appears,
informing that the RT-Controller did not respond.
Figure 35: Dialog window informing that no connection to the real-time software is possible.
SOLUTION: Click on “Install Software” to reinstall the real-time controller software. If the software has been
started less than 60 seconds before the RC5 has been powered on, please click on “Try again” first.
REASON: Outdated software installed on real-time controller. The following dialog window appears.
Figure 36: Dialog window informing that the software installed on the real-time controller needs to be updated.
SOLUTION: Please follow the instructions given in the Real-time software update section above.
REASON: Wrong license file. The MAC addresses in the field “Licensed MAC address” and “Available RT-
Controllers” (see above) are different.
SOLUTION: Make sure that the correct license file has been selected. The license files are bound to a specific
RC5, therefore license files for other RC5s will not work.
License file issues
SYMPTOM: The “License file valid” LED in the startup screen of the software is dark.
REASON: The license file has been tampered with, or has been generated incorrectly.
SOLUTION: Retrieve the original license file and try again. If this does not solve the issue, please contact
SPECS.
SYMPTOM: The “Not Expired” LED in the startup screen of the software is dark.
REASON: The license file has expired. This is the case for time-limited licenses.
SOLUTION: Use a license file with no time limitation. If not available, please contact SPECS.
SYMPTOM: The “Correct Version” LED in the startup screen of the software is dark.
REASON: The license file is intended for a different version of the software.
SOLUTION: Use the license file sent with the RC5. If the file cannot be found, please contact SPECS.
RC5 Real-Time Controller Troubleshooting

Instrument doesn’t power up correctly
SYMPTOM: The Power LED (1) does not light up.
REASON: Fuses blown.
SOLUTION: Disconnect the RC5 from the mains. Remove and check the fuses (3). If the fuses are blown,
replace them with fuses of the same rating (T2A), and try powering up the RC5. Should the fuses
blow again, please contact SPECS.
REASON: RC5 damaged.
SOLUTION: Disconnect the RC5 from the mains. Remove and check the fuses (3). If the fuses are intact, but the
unit is still not working, please contact SPECS.
SYMPTOM: The instrument turns on, but does not respond when starting the software. The “DRIVE”
LED (see picture below) at the back of the RT-unit does not light when powering the RC5.
REASON: Hard drive failure.
SOLUTION: A hard drive failure is very unlikely, but cannot be ruled out. In the case of a hard drive failure, the
“DRIVE” LED at the back of the RT-unit does not light up when powering the RC5 (see picture
below for the location of the LED). Please note that during normal operation the LED is always
off, therefore a hard drive failure can only be detected by observing the LED when powering the
RC5. If the hard drive has failed, please contact SPECS.
Figure 37: Location of the "DRIVE" LED indicating normal functioning of the hard drive during start-up of the RC5.
SYMPTOM: The instrument turns on, but does not respond when starting the software. There is no
indication of faults.
REASON: Corrupt file system, or network-related issue (see above).
SOLUTION: Connect a computer screen to the DisplayPort connector as explained in the Connection to
computer screen section. The status information shown on the screen should appear as shown in
the picture below. If the displayed information should be different, please take a picture of the
screen and contact SPECS.

Instrument is overheating
SYMPTOM: Response of the software user interface is sluggish. TCP communication breaks down or
error messages appear.
REASON: Ventilation is insufficient or the environment temperature is above specified operating conditions.
SOLUTION: Relocate the RC5 to an open space, if it was previously put in a rack or at a location with poor
ventilation. Make sure that the cooling-air exhaust at the back of the unit is not obstructed, and that
warm air is not redirected to the cooling-air intake at the bottom of the RC5. If the environment
temperature exceeds the specified operating conditions, turn on air conditioning, if available.
REASON: Air intake at the bottom of the RC5 is obstructed.

SOLUTION: Make sure that the air intake at the bottom of the unit is not covered by any object, and that there is
no object placed anywhere between the RC5 bottom panel and supporting table. Make sure that the
plastic feet supporting the instrument have not been removed.
REASON: Air intake at the bottom of the RC5 is obstructed by dust.
SOLUTION: Make sure that there is no dust covering the air intake at the bottom of the RC5. If there is dust on
the intake cover, remove the dust carefully with a dry cloth. Take measures to avoid that dust can
reach the air intake.
REASON: Cooling fins of the CPU heatsink are filled with dust. The top cover of the instrument needs to be
removed in order to verify this. Instructions for how to remove the cover are given in the Optional
OCXO clock mounting instructions section.
SOLUTION: Remove the instrument top cover as explained in the Optional OCXO clock mounting instructions
section. The location of the heatsink is shown in the figure below. Remove the dust with a plastic
tool. Do not use a cloth (electrostatic discharge!) or a vacuum cleaner for this purpose. Note that, if
dust has accumulated inside the CPU heatsink, it is highly probable that the air intake cover at the
bottom of the RC5 is also obstructed by dust. Clean that air intake as explained above, and take
measures to avoid that dust can reach the air intake.
Alternatively, remove the complete RT-unit as shown below, in order to facilitate the removal of
the dust.
Figure 40: Location of the RC5 CPU heatsink.

Clock issues
SYMPTOM: The instrument turns on, but does not respond when starting the software. An external clock
source is used and none of the Clock source LEDs (12) is on.
REASON: The clock signal generated by the external clock source does not have the correct frequency or
amplitude, its rise time is too slow, or the duty cycle is different than 50% by a too large amount.
The RC5 recognizes that a signal is applied to the CLOCK IN connector (12), but is not able to
lock on it.
SOLUTION: Make sure that the clock signal complies with the frequency, amplitude, rise time, and duty cycle
specifications given in the Clock ports specifications section above. If the source does not comply,
either use the internal clock or a different clock source. If the source does comply, but the RC5
does not lock on the clock signal, please switch off the RC5 and switch it on again. If the clock
signal is still not recognized, please contact SPECS.
SYMPTOM: A Nanonis OC4 is connected to the RC5, but the INT Clock source LED (12) is on instead of
the OC LED.
REASON: The OC4 is not connected to OC4 device connector 01 (7).
SOLUTION: Make sure that the OC4 is connected to the OC4 device connector 01 (7). Only the OC4 connected
to this connector can be used as a clock source for the RC5.
REASON: The OCXO inside the OC4 is disabled, or the OC4 is configured for the use of an external clock.
SOLUTION: Please contact SPECS for instructions on how to change the clock settings of the OC4.
SYMPTOM: An OCXO has been installed in the RC5, but the INT Clock source LED (12) is on instead of
the OCXO LED.
REASON: Incorrect frequency or voltage specifications of the OCXO.
SOLUTION: Please make sure that the OCXO has a frequency of 10 MHz and operates with a voltage of 3.3 V.
REASON: The OCXO has been mounted upside down.
SOLUTION: Please check that the OCXO has been mounted as described in the Optional OCXO clock mounting
instructions section. The sharp edge of the OCXO marked by a dot must show towards the rear
panel of the RC5.
