Thank you for purchasing this product
The KC keypad controllers have been designed with the professional installers in mind.
The many extensive features will assist you in implementing the required system control
quickly and help with integration, validation and maintenance.
Installation precautions
This product has special circuitry to protect it against moderate surges and static
discharges. However, to ensure reliable operation and long service life, it is important to
take the necessary precautions against any spikes, surges and static discharges.
Place the units away from sources of heat and/or moisture.
As much as possible, long cable runs should be routed away from any noisy sources and
avoiding long runs in close proximity to AC mains cables.

The KC range of keypad controllers are easy to configure and are packed with a wide
range of interfaces (RS232, RS485, Ethernet, IR, and digital I/O), making them an ideal
controller either as a stand-alone device or as part a larger distributed control system.
The integrated IR learner simplifies the inclusion of any new device with IR requirements.
The Codeless methodology (No-code) enables easy configuration of the KC series by
accessing a vast array of device libraries for effortless implementation. Complex functions
are easy to implement without the need for any programming skills. For more
sophisticated requirements, the units are programmed in Lua, achieving even more
amazing functions simply and easily.
The easy to operate NebulaStudio® environment facilitates your requirements to achieve
all the desired functions (codeless or coded). For a complex multi-controller system, the
meshing facility makes the implementation easy, especially for future changes or
upgrades.
The large elegant buttons are backlit with RGB LED which can be set to any colour /
intensity required. Each button can be labelled, and protected with a clear cover cap. The
versions with the rotary dial (volume control) also have a bar graph to show the set level.
The Ethernet / LAN port option facilitates control of IP enabled devices, as well as
accepting PoE power for a more cohesive system.

Fitting the Button Legend and Clear Cap
Remove the desired legend from the legend sheet provided and affix it to the top of the
button, then carefully fit the clear cap to protect the button legend.
Using the Cap Removal Tool (SY-CRT)
1. Carefully insert the Cap Removal Tool between the button and faceplate opening.
2. Gently pull the Cap Removal Tool (CRT) in an UPWARDS direction away from the
faceplate surface. DO NOT attempt to lever off the cap, as this action may damage the
button. You can gently try two or three sides to loosen the cap off the button.
3. Please avoid excessive force and be gentle, as otherwise you may damage the button.

Using this Product
1. The KC keypad controllers can be configured or programmed using the
NebulaStudio®. This is quite intuitive and flexible, allowing complex control and
set ups in a very short time. The vast array of third-party device libraries simplifies
the implementation. Adding new commands to the library is simple and quick.
Each button can have multiple functions, with any desired colour. The final
program can be downloaded into the KC keypad controller via the USB-C port.
2. Using the legend sheet, each button can be individually labelled before fitting the
clear cap to protect the label.
3. Connect to the RS485 / RS232 serial, I/O, or IR ports as required.
4. If required, connect the LAN port to the network using Cat5/6 cable.
5. Connect the 12V DC power supply (Not required if PoE LAN port is used).
Using Built-In IR Learner
This feature is supported on all the KC series keypads. The IR Learner sensor is located
beneath the IRL aperture on the rear of the keypad. Use NebulaStudio® to perform the IR
learning and then assign the captured IR Remote commands to a library file.
Using the Serial Ports
The KC keypads have 6 Comm Ports, which can be set to the following parameters:
Baud rate: 600 to 115,200
Data bits: 8 or 9
Parity: None, Odd or Even
Stop bits: 1 or 2
All the ports are protected against short circuit as well as ESD.
Flexi-Ports
Port 5 and Port 6, are multifunction serial Flexi-Ports:

The Flexi-port functions can be easily configured within NebulaStudio®. Flexi-Port 6 also
requires switch settings on the side of the back-panel as described on page 7.
Comm Ports 1-4
Comm Ports 1, 2, 3, and 4 are dedicated Bi-directional Full-duplex RS232 ports (Tx, Rx).
Flexi-port 5 –RS232 or IR
Com Port 5 is a Flexi-port and can be configured in 3 ways:
Full-duplex RS232 (Tx, Rx)
RS232 Tx with 1x Infra-Red output (IR2)
2x Infra-Red outputs (IR1, IR2). (See Flexi-port Examples).

V1.0 7sy.uk
Flexi-Port 6 –RS485, RS232, or IR
Comm Port 6 is a Flexi-port and can be configured in 4 ways:
Half-duplex RS485
Full-duplex RS232 (Tx, Rx)
RS232 Tx with 1x Infra-Red output (IR4)
2x Infra-Red outputs (IR3, IR4). (See Flexi-port Examples)
There are two switches on the side of the back-panel that set the mode of Flexi-port 6.
When viewed with the faceplate at the bottom, the upper switch selects between RS485
or RS232/IR mode. The lower switch selects whether the RS485 data lines are terminated
to 120R or are unterminated. This lower switch has no function when using RS232 or IR.
Port 6 –RS232/IR Mode
Port 6 –RS485
Unterminated
Port 6 –RS485 Terminated
The bottom switch has no
function in this mode
The bottom switch set to
― position (Not Terminated)
The bottom switch set to
120R position (Terminated)
For RS485 please note the following:
The RS485 Termination should be set when the KC keypad is at the end of a cable run.
The RS485 cabling should be a twisted pair to minimise induced interference.
Both the A and B connections must be present for RS485 to operate reliably.
When using shielded cable, connect the shield to the terminal Port 6 ground.
Flexi-port Examples
In each of the following diagrams, the top switch is the one furthest from the faceplate.
The switch shown in grey has no function in the RS232 or IR modes.
Bidirectional RS232 (Tx, Rx)
This diagram shows Full-duplex RS232 connection to the Dsub-9 connector. Always refer
to the third-party product manual to determine the actual connector type and wiring. All
ports (1 ~ 6) can be connected in this manner (Set switch to RS232 mode for Port 6).
Note: The bottom switch has no function when the top switch is set to RS232 mode.

RS232 Tx, with 1x IR on the same port
This configuration applies to port 5 and port 6.
Two IR Outputs
Port 5 and Port 6, each can be configured as two IR outputs:
RS485 on Port 6 Only
Port 6 can be set to RS485 mode by setting the two switches on the side of the KC keypad:
Note: The termination must only be set when the KC keypad is as an “end device” at the
end of the RS485 cable run. Commands are assigned in the same manner as for RS232
commands in the NebulaStudio®.

Using the Digital I/O Ports
Each of the 4 digital I/O ports may be configured as either input or output:
An input port can accept any voltage up to 24V DC.
An output port can tolerate up to 24V and switches to 0V (max of 200mA sink
current).
Each output is overcurrent protected.
Each output can directly drive a 12V relay coil (back EMF protected).
The + output pin provides 12V supply to 200mA maximum (with Resettable fuse).
NOTE: In each of the following example diagrams, the referenced connections to I/O1 and
I/O2 can also be applied to I/O3 and I/O4. The below are just some sample possibilities.
Driving Two Relays
No additional diode protection is required, as all KC I/O ports are fully protected against
any back EMF.
One Relay and One Input Connection
Input 1 can alternatively be configured as an output port.
Digital and Switched input
The input 2 can alternatively be configured as an output port. Note that all I/O ports have
internal pull-up resistor; as such direct connection to a switch is possible.
Using the Ethernet Port
The Ethernet option must be specified when ordering. The commands for the Ethernet port
are programmed from NebulaStudio® to allow the KC keypad to send commands to IP
controlled devices. The KC keypad can be powered from a PoE enabled Ethernet port.
Up to 128 network devices can be controlled by KC Keypad controller.

sy.uk 10 V1.0
There are two indicator LEDs on the RJ45 connector:
The Yellow LED indicates network activity and flashes whenever any network data
traffic is detected.
The Green LED indicates the presence of the Link carrier signal.
It remains lit, indicating good connection with the connected network device.
RJ45 Cable Termination
It is recommended for the network cable to be wired at each end to T-568B specification:
