The RC1xx has an ingress rating of IP20 and it should be sited so that water
or dirt cannot enter the unit.
6 Connecting the RC1xx
Refer to Section 11, “RC1xx reference information” for the ratings of the
connections. The RC1xx’s connections are shown below (an RC120 is
illustrated):
6.1 Power
Any power supply derived from mains electricity must have a Safety Extra
Low Voltage (SELV) output. Route low voltage wiring to the RC1xx controller
separately from mains electricity wiring. If this is not possible, make sure
the low voltage wiring has an insulation rating that is appropriate or
supplementary insulation is used. The connections are shown below:
6.2 Lighting output
Note: Make sure you set up the current or voltage rating for the light
before you connect it See Section 10.1, “Lighting setup”.

RC1xx LED Lighting Controllers - User Manual

The lighting output connections must not be commoned to any other
controllers or grounded in any way. The connections are shown below:
6.3 Trigger input
The trigger input is a Smart Input; it accepts a range of trigger sources with
minimal extra circuitry. Refer to Section 7.2.1, “Trigger input options” for
further information.
Note: The Smart Input is not isolated, it is ground referenced to the power
supply negative connection.
In operating environments where there is a high level of radiated electrical
noise, use a shielded cable for the trigger input as shown below:

RC1xx LED Lighting Controllers - User Manual

7 General description
Three modes of operation are provided for the light output:
Continuous – the output is constant, but variable between 0% and
100% in steps of 0.1%.
Pulse (strobe) – the output is pulsed once per trigger. The delay from
trigger to pulse, the pulse duration and the brightness can all be set.
Switched – the trigger input can be used to switch the output current
on and o.
The set-up is non-volatile, so the RC1xx resumes the same operation after
a power cycle.
7.1 Pulse and duty cycle limits
The output is o by default. Upon being triggered, the RC1xx pulses to the
output after a delay. The delay, pulse width, re-trigger delay, and pulse
intensity are all congurable (see Section 9, “Web page conguration
(RC120)”, or Section 10.3.4, “Lighting commands”, or Section 10.2, “Front
panel commands”).
In pulse and switched modes, the brightness can be set up to 1000% of
its rating for short periods and low duty cycles. To avoid damage to the
lighting, the RC1xx limits the duty cycle by ignoring triggers that are too

RC1xx LED Lighting Controllers - User Manual
—13 —
soon after the previous trigger. The maximum pulse width and duty cycles
are shown below:
Output
brightness
Maximum
pulse width
Maximum
duty cycle
0 to 100% 100ms 100%
101% to 200% 30ms 30%
201% to 300% 10ms 20%
301% to 500% 2ms 10%
501% to 1000% 1ms 5%
So for example, if the brightness is set to 250%, then the RC1xx does
not allow pulses greater than 10ms long. With 10ms pulses, any trigger
occurring within the next 50ms is ignored as the duty cycle would be
greater than 20%.
The RC100 pulsed current cannot exceed 1.0A, so for a lighting rating of
0.1A, 1000% brightness is possible. For 0.25A lighting rating the maximum
brightness is 400%.
Similary the RC120 pulsed current cannot exceed 2A, so for a lighting rating
of 0.2A, 1000% brightness is possible. For 0.5A lighting rating the maximum
brightness is 400%.
7.2 Triggering
Trigger pulses should have a minimum pulse width of 2μs. You can set
the sense of the RC1xx trigger input. Do this by setting the P ag from
the front panel (see Section 10.2, “Front panel commands”), the web page
(see Section 9, “Web page conguration (RC120)”) or the RE command (see
Section 10.3.3, “General commands”). The eect of setting the P ag is
summarised below:
Mode Flag state Eect
Continuous Unused Output is on.
Switched P Flag = 1 Output is o when trigger is o.
Output is on when trigger is on.
P Flag = 0 Output is on when trigger is o.
Output is o when trigger is on.
Pulsed P Flag = 1 Pulse is triggered on rising edge.
P Flag = 0 Pulse is triggered on falling edge.
Note: The P Flag inverts the sense of the trigger.

RC1xx LED Lighting Controllers - User Manual
—14 —
7.2.1 Trigger input options
You can connect the following types of trigger to the Smart Input:
3V to 24V voltage source
Any voltage between 0V and 0.9V is
taken as logic 0.
Any voltage between 3V and 24V is
taken as logic 1.
TTL signal
You can connect a TTL signal to the
RC1xx’s input. However, a 3.3V TTL
signal only works if it can drive 8kΩ
without dropping below 2.7V.
If the P ag is set to ‘1’, the RC1xx
output turns on when the TTL driver
goes HIGH. To reverse this, set the P
ag to ‘0’ (see Section 7.2, “Triggering”).
NPN signal
You can connect an NPN open collector
drive to the RC1xx’s input. Use the
connections shown opposite.
If the P ag is set to ‘1’, the RC1xx
output turns on when the driving
transistor turns on. To reverse this,
set the P ag to ‘0’ (see Section 7.2,
“Triggering”).
Opto-coupler
You can connect an opto-coupler as
an NPN drive to the RC1xx’s input. This
prevents a ‘ground-loop’ and reduces
spurious triggering in high-interference
environments.
If the P ag is set to ‘1’, the RC1xx
output turns on when the driving
transistor turns on. To reverse this,
set the P ag to ‘0’ (see Section 7.2,
“Triggering”).

RC1xx LED Lighting Controllers - User Manual
—15 —
PNP signal
You can connect a PNP open collector
drive to the RC1xx’s input. Use the
connections shown opposite. The PNP
transistor should not pull up to more
than 24V.
If the P ag is set to ‘1’, the RC1xx
output turns on when the driving
transistor turns on. To reverse this,
set the P ag to ‘0’ (see Section 7.2,
“Triggering”).
7.2.2 Internal trigger
You can set the RC1xx to generate its own trigger pulses. The period of
these pulses can be set in increments of 100μs from approximately 10ms
to 5000ms.
You can set the RC1xx to produce a single pulse for testing purpose. This is
set by either a TR1 command (see Section 10.3.3, “General commands”) or
using the web page Trigger button (see Section 9, “Web page conguration
(RC120)”).
7.3 SafeSense
The SafeSense feature of the RC1xx operates automatically. After setting
the rating for the light, the RC1xx senses the light on connection for its type
and characteristics. The unit does not need to sense the light again unless
the light has changed or the RC1xx has been power-cycled.
For further information on this feature, see the application note, APP936 –
SafeSense Technology, available from www.gardasoft.com.
7.4 SafePower
The RC1xx’s SafePower needs no intervention from the user for its
operation. The advantages of SafePower are:
»Heat dissipation in the controller is very low
»The load voltage can be higher than the supply voltage
»High continuous currents can be output with a reduced need for
heatsinking
For further information on this feature, see the application note, APP966 –
SafePower Technology, available from www.gardasoft.com.
7.5 Light characterisation
You can reduce the time it takes for your RC120 controller to reach high
accuracy in time-critical machine vision systems when changing from one
overdrive brightness setting to another. This can be done by instructing the
controller to make current and voltage measurements up to a customer

RC1xx LED Lighting Controllers - User Manual
—16 —
specied brightness limit when the light is characterised. This is called
the characterisation limit. The measured overdrive voltage and current
relationship is stored in the RC120 and allows it to respond much more
rapidly to new overdrive parameters up to that limit.
When a light is detected, the characteristics of the light are measured up to
the brightness set for the characterisation limit. It is not essential to set this
value and it can be left at 200 (meaning 200% brightness). The feature can
also be turned o by setting this value to 0.
You can change the characterisation limit brightness through the RC120’s
web pages (see Section 9, “Web page conguration (RC120)”) or by
command (see Section 10.3.4, “Lighting commands”).
7.6 Current adjust
The current adjust feature provides a more accurate and repeatable
output current. After setting an output current, the controller continually
measures the actual current and adjusts the output to maintain the target
current. This will compensate for any inaccuracies such as temperature
drift in the controller.
If the output current is less than 100mA, the adjustments the feature
imposes can have a signicant eect on the lighting brightness. If some
ickering is seen, it is recommended that the current adjust feature is
turned o.
Current adjust can be turned on and o from the RC120’s web pages (see
Section 9, “Web page conguration (RC120)”) or by using the RE command
(see Section 10.3.3, “General commands”).
7.7 Flags
You can set ags on the RC1xx controller to alter its operation. They can be
set from the unit’s front panel, the web page or through the RE command
(see Section 10.3.3, “General commands”). The following conguration ags
are available:
E Flag – Enables or disables fault detection. Error checking is enabled
as the default setting.
P Flag – Sets the trigger input active high or active low. The default
setting is active high. Refer to Section 7.2.1, “Trigger input options” for
a detailed description of the settings.
S Flag – Sets the SafeSense feature of the RC1xx. When cleared it
removes the SafeSense light detection and the controller assumes a
light is connected. The default setting is for SafeSense to be enabled.
This ag cannot be used when the light is set according to its voltage
rating. The S ag cannot be changed from the RC1xx’s front panel.

RC1xx LED Lighting Controllers - User Manual
—17 —
7.8 Fault detection
The RC1xx can detect a range of errors when connected to a light. The
displayed error codes are shown below with their reasons.
Error Reason
PO Internal power dissipation too high. Output turned o.
OP Output current to lighting is too low. The light is open
circuit or there is not enough supply voltage for the
requested current.
Sh Output voltage is too low. The RC1xx detects that the
output is short-circuited.
HI The voltage required for the lighting has increased too
much. Check for ageing of the light or a failed LED.
LO The voltage required for the lighting has decreased too
much. Check for ageing of the light or a failed LED.
Note: When the output current falls below 100mA, some fault detection is
disabled. Press SEL to cancel the error and allow the RC1xx to sense the
light again.
7.9 Factory settings
You can clear the RC1xx conguration to return it to its factory settings:
The lighting rating is cleared and the light does not illuminate.
Clear the conguration from the front panel by pressing and holding SEL
and for about 5 seconds, until COL is displayed. You can also clear the
conguration by using the CL command (see Section 10.3.3, “General
commands”).
You can start the RC1xx from a powered down state (cold boot) with the
front panel keypad locked; this process removes the keypad lock.
8 Ethernet address (RC120)
You may need to ask your network administrator for advice about setting
up the Ethernet connection.
The application note APP923 – Troubleshooting Ethernet problems is
available from www.gardasoft.com/Downloads.
The Ethernet set up of the RC120 is not aected by cold-booting the
controller.

RC1xx LED Lighting Controllers - User Manual
—18 —
8.1 IP address
The RC120 needs an Internet Protocol (IP) address to communicate over
Ethernet. There are two ways to get an IP address; either programmed into
the unit or using DHCP.
For DHCP mode, the RC120 acquired its IP address, subnet mask, and
gateway address from the DHCP server. Otherwise the RC120 has a xed IP
address, subnet mask, and gateway address.
DHCP mode or the IP address can be set or read using the GardasoftMaint
program available from www.gardasoft.com.
The GardasoftMaint window is shown below:
GardasoftMaint allows you to view the controllers on your network, change
their IP addresses and upgrade their rmware if it becomes necessary.
In the messaging section of GardasoftMaint, you can communicate with
your controller using the commands explained in Section 10.3.3, “General
commands” and Section 10.3.4, “Lighting commands”. You can also open
the selected controller’s web pages at the click of a button. For more
information about the RC120’s web pages, see Section 9, “Web page
conguration (RC120)”.
8.1.1 DHCP
Most networks use a DHCP server. If there is a PC on the network, you
may be able to nd out whether a PC on the same network uses DCHP as
follows:

RC1xx LED Lighting Controllers - User Manual
—19 —
i. Right-click the Windows 10™ icon at the left of your PC’s task bar.
ii. Select Network Connections.
iii. in the Status pane, click on View your network properties.
iv. DHCP enabled will be set to ‘yes’ if DHCP is in use.
You can nd out what IP address is being used by a PC at any time by
following the steps below:
i. Right-click the Windows 10™ icon at the left of your PC’s task bar.
ii. Select Network Connections.
iii. In the left hand pane, click on Ethernet.
iv. Click on your network icon under Ethernet.
Your IP address will be given as the ‘IPV4 address’.
8.1.2 Fixed IP address
When using a xed IP address, you must ensure that you use an IP address
that is not being used by any other device on the network. It is usual to
keep the rst three numbers of the IP address the same as other devices
and to change only the last number. For example, if you have a network
consisting of a PC (IP address 192.168.1.35) and two RC12xs, they could be
allocated addresses 192.168.1.201 and 192.168.1.202.
8.2 Automatic sensing
The RC12x ends out a message on three events:
»On power up,
»When an IP address is received or renewed by DHCP, and
»When an enquiry message is received
On the rst two events, the message is broadcast. On the third it is a reply
to a single IP address.
An enquiry message is a UDP packet from source port 30310, destination
port 30311 with the message body ‘Gardasoft Search’ (8-bit ASCII, 16
characters).
The message output by the RC12x is a UDP packet from source port 30311,
destination port 30310. It is formatted as:
Gardasoft,RC12x,000000,111111111111,22222222
(8-bit ASCII, 44 characters), where:
000000 is the serial number of the unit
111111111111 is the MAC address in 6 HEX bytes
22222222 is the IP address in 4 HEX bytes

9 Web page conguration (RC120)
You can set up the RC120 through its own internal web pages. After
locating your controller on your network, click the Open webpage... button
in GardasoftMaint to take you directly to the RC120’s web pages. You can
also type the controller’s IP address (displayed in GardasoftMaint) into your
web browser, which will display the Main page. GardasoftMaint software is
available from www.gardasoft.com.
9.1 Main page
The main page (shown below) is the rst to open when you access the
RC120’s web pages. This gives the controller’s hardware and rmware
revision levels and the serial number. It also tells you the power being
dissipated and the RC120’s internal temperature.
9.2 Conguration page
The conguration page allows you to set up the lighting parameters,
view the light data, and view the measurements the RC120 makes
during operation. To refresh this page it is important that you click the
Refresh button on the web page () rather than on your web browser.
When conguration changes are submitted, the URL includes the new
conguration, so refreshing the page re-submits the URL.
You can set the mode (continuous, pulsed, or switched), the light’s
brightness and pulse settings. You must click the Submit button to eect
any changes you make.
Click the Refresh button at the bottom of the screen to update the
measurements being taken.
