Figure 1 shows a small domestic installation of a RAK4 based system. There are 6 circuits spread across 2 rooms. In one room, the Lounge, there are two wireless wallplates. Each RAK4 unit has 4 channels, so there are 2 RAK4’s on the system to achieve the 6 circuits required. An RxLink receives the radio commands from the wallplates and passes that information to the correct channels on the RAK4 cards. Page 2 of 20

Wiring the RAK4 cards The RAK4 casing shall be screwed to the wall in appropriate electrical installation location. The casing has TWO busbars fitted to it. The upper busbar is for Earth connections. All RAK4 earth busbars should be connected to each other & to the supply & load earth wires. The lower Busbar (with Blue insulated mounting) is for Neutral. Make sure the RAK4 neutral & the busbar neutral are linked. The busbar must be connected to all the load Neutrals and to the supply Neutral. A common mistake is to connect the supply Neutral to the RAK4 card directly, but not to the Busbar. This causes RAK4 to appear to operate normally, but none of the loads will light.

Connect an Rx-Link to the “IN” connector of one of the RAK4 boards. Use one of the supplied RJ45 patch leads to connect the “OUT” connector of that RAK4 to the “IN” connector of the next RAK4. Up to 4 RAK4 cards can be interconnected in this way. (Actually it doesn’t matter on RAK4 which RJ45 connector is IN and which is OUT - they are the same really).

Perform basic health check of system A basic health check of the system can be done at this stage. In order for the check to work correctly the following must be observed: • Leave all Address Switches on the RAK4 cards in the Off position • Use an Rx-Link that is straight out-of-the-box with it’s original factory settings. • Use a Wireless wallplate that is on factory default settings: House 1, Room 4. (This is with House switch 1 set ON and Room switch 3 set ON – all other switches OFF) Check all circuit wiring for basic safety, then apply power to all the RAK cards. On every RAK4 the “Power” LED should illuminate. Each circuit on each RAK4 should come on – dimming up from zero to maximum in 3 – 4 seconds from power on. When the buttons on the wallplate are pressed, the “Link” LED on each RAK4 should flash. All circuits on all RAK cards should respond to the wallplate. Each circuit on a RAK has an indicator LED which should also respond to the wallplate. If the system responds correctly to this basic test, then proceed confidently to program the system.

START PROGRAMMING THE SYSTEM RAK4 systems can only be programmed using the Rako RASOFT software. Normally this is done on a Windows PC. The PC needs a Programming Adapter to talk to the Rako Wireless system. This is normally a RAUSB or a RAKO Bridge (RA-Bridge or RTC-Bridge) See Appendix 3 for details of connecting RASOFT to a programming adapter.

Create a new Rasoft Project File Start up the RASOFT software on the Laptop PC. The main Rako home screen should appear. If any error messages occur during program load, select ignore or OK. Notice that this screen only has “Rako” written at top left hand corner. This means we are editing the default Rako project file. DO NOT Use this Default Rako File to program a system. The information is likely to get overwritten or deleted at any time. Press “File” then “New” to clear out any information from previous Projects. Then press “Save” to create a new project file. Page 4 of 20

Press the “Save and edit” button Give the file an appropriate name and save it in a Folder that can be found later. (Wireless Demo in this instance)

Now the project file is called “Wireless Demo” Go to the “Controls” – “Communications” screen & select the correct programming adapter settings (see Appendix 3) Hint. Once the file has been saved it is better to open it by double clicking on it directly from the Windows desktop. Don’t open Rasoft then use “File” – “Open” as this causes re-initialisation of the communications to the RAUSB or Bridge & is time consuming.

Choose and Set a House Number Every Rako Wireless system has a House Number. Normally this is set to be the same as the house number of the street address of the property where the Rako system is being installed. The purpose of the House Number is to prevent systems in adjacent properties interfering with each other. The method to change the House Number depends on the type of Programming Adapter that is being used to interface the Rasoft PC to the system. Normally this will be a RAUSB adapter or one of the Rako Bridge products (APR-Bridge, RA-Bridge, RTC-Bridge etc).

Setting House number: If using a RAUSB In the RASOFT Home screen (as shown above) change the House Address field to a new number. For this document the house number 65 shall be used.

When changing the House Number, RASOFT will give a warning message to check that you really want to do this. Press “OK” Hint: Do not leave the House Number as one. House 1 is the Rako factory default which all brand new product is set to when leaving the factory. Of all the house numbers available, it is the one most likely to experience interference with other nearby systems

Page 5 of 20

Setting House number: If using a Rako Bridge. Refer to Appendix 3 which shows how to connect to a RAKO Bridge and set it’s House Number.

Configure the Rx-Link(s) to the new House Number The Rx-Link handles the translation between the Channel Control room & channel names with the actual RAK4 circuits that are physically wired to the lights. Make sure the RAK4 cards are powered up & the RXLink is correctly connected to them. Close the Channel Controls window.

Magnet

Then in the Home Screen select Controls – Mapping (RxLink)

Hold a magnet against the RXLink so that it’s internal LED lights up. Hold the magnet in position until the LED starts to blink.

When the RXLink LED is blinking, Select RXLink No 1 from the drop down box and highlight “Room255 Channel 1” in the top right hand text box. Press the Ident Button in the Receiver Mapping screen

If there is more than one RxLink on the system, then select RxLink No 2 from the Drop Down box and Press “Add New Receiver”. Similarly for RxLink No 3 and so on. Press “Refresh” to make the new receivers appear on the list. The new receivers will then need to be Idented in the same way as the first one, by first using the magnet, highlighting each one and pressing Ident. Set one wallplate to the new House number and use it to check that the RxLinks respond to the new House number by repeating the Basic Health Check. Leave the wallplate Room address as Room 4 at this stage. (See section “Set the Wallplate Addresses” to see how to set the correct wallplate address) Page 6 of 20

Set the address switches on the RAK4 cards. Each Rx-Link can be used to interface up to FOUR RAK-4 cards . (This can be any mixture of RAK-4, RAK-4L and RAK-4F). Each RAK-4 needs to be given a different address to any other RAK-4 that is connected to the same Rx-Link. This is so that the correct commands are sent to each one. The addresses are set by the DIP-Switches on each RAK-4. These switches are easily seen near the top edge of each RAK card. The address is set by switch positions 1, 2, 3 and 4. The coding for the switches is as shown in table below. Switch 1 Switch 2 Switch 3 Switch 4

RAK 0 DOWN DOWN DOWN DOWN

RAK 1 UP DOWN DOWN DOWN

RAK 2 DOWN UP DOWN DOWN

RAK 3 UP UP DOWN DOWN

In the installation of Figure 1 we shall have the Top RAK-4 set to address 1 and the lower RAK-4 set to Address 0. (At this point, RAKs will respond as follows: RAK0 = room 4, RAK1 = room 5, RAK2 = room 6, RAK3 = room 7)

Identify which lights are connected to which RAK circuits. Normally this information is provided by the electrician who has done the wiring. But, there is often some confusion about which circuit is which. A RAK-4 card has four outputs. These are circuits 1,2,3,4. The terminal block on the RAK-4 is clearly labelled as such. For our installation here we have six circuits. These just happen to be wired as follows: CIRCUIT NAME Lounge Chandelier Lounge Standard lamp Lounge table lamp Dining Room Spots Dining Room Standard lamp Dining Room pendant

RAK Number 0 0 0 0 1 1

RAK Circuit 1 2 3 4 1 2

If you are not sure which circuit is which, there is an easy way to find out. Use the DIP switches on the RAK4 cards. Switches 5,6,7,8 can be used to toggle the RAK outputs on and off. The boards have to be powered up for this, so careful with the LIVE HEATSINKS etc! DIP Switch up to turn the circuit ON and switch down to turn it OFF. You’ll be able to see what you’re doing as each circuit on the RAK4 has an LED that lights up when the circuit is ON. So, just see which lights in the house operate when you move the DIP switch up/down. Leave the switches 5,6,7,8 in the OFF (Down) position when you’ve finished with them.

Create Rooms and Channel Names Go to the “Channel Controls” window by selecting “Controls” and then “Channel Controls” To start creating Rooms, Click on “Add” (Hint: Don’t worry about which circuits are connected to which RAKs at this stage. Just think about what Lights are in what rooms) (Hint: Avoid using Room Numbers 1,2,3 and any room number that is a multiple of 4. See section “Group settings and Ignores” for details). Type Room name (Dining Room) Manually Select a Room Number (5) Press “Add” again Change Room name (to Lounge) Select a different Room Number (6) Press “Add” once more Press “Quit” Now the Lounge and Bedroom appear in bottom RH of the Channel controls window as rooms 6 and 5. The Default Room 4 can be deleted at this point.

Page 8 of 20

In Bottom RH corner: Highlight the “Dining Room” by clicking on it. (Dining Room will appear in the Room Name position at top of the Channel Control screen).

Then Type in the names of the circuits that exist in the Dining Room. (Hint: Again Don’t think about what RAK’s these circuits are connected to. Just get all the circuits listed into the correct room)

Repeat for the Circuits in the Lounge

Map RXLink Channels & Circuits Refer to the list of RAK circuits made previously (repeated here) CIRCUIT NAME Lounge Chandelier Lounge Standard lamp Lounge table lamp Dining Room Spots Dining Room Standard lamp Dining Room pendant

Staying in the Receiver Mapping screen , make sure RxLink No 1 is selected & “Room255 Channel 1” is highlighted. The bottom half of the window shows a large text area (Mapping List) with a single “Disabled” entry. (If this disabled entry is not present then press the “Add” Button at the bottom of the window to create it). Click on “Disabled” to highlight it. Click in the “Active” check box to make a tick appear in it. Click the Room drop down list and select “6 Lounge” Click the Channel drop down list and select “2 Chandelier” Click the Box drop down list and select “0” Click the Circuit drop down list and select “1” (because the Lounge chandelier is connected to Box 0 circuit 1) Press the “Refresh List” button. The new mapping should appear in the Mapping List as below.

Use the Add button to create further Maps and edit them until all the RAK circuits have been added.

Press “Upload All” to send the mapping information to the highlighted RXLink. Highlight any other RxLinks and upload them in turn. If everything has gone well so far, the system should now respond to the correct room commands. Test this by going to Channel Controls screen, select one of the rooms and see that the room responds to the scene buttons. Page 10 of 20

Set the Wallplate Addresses Go to Wallplate 3 in the dining room and remove its rear cover. There are two sets of DIP Switches in the wallplate. RASOFT has a help screen to set these switches. In the Home Screen press the Help Menu and select “Switch Settings”. You will see the following screen Type your House Number (eg 65) in bottom Left hand text field. Type Room Number (5) in bottom Right hand text field. The screen will show the switch positions for the correct house & room numbers. Set the wall plate switches to be the same as those indicated.

Repeat for the other wallplates around the system.

The entire system should now be operating with each room responding to the wallplates within it.

Page 11 of 20

Create Scenes

Factory settings for each dimmer are fine, but don’t provide any imaginative mood settings for the rooms. These can be easily set up from the Channel Controls screen. • Highlight an appropriate room (eg Dining Room) • Select a Scene (eg Scene 2) • Move the sliders for each channel left/right until the desired lighting effect is achieved. • Press Store. Each scene can be given a name. This will be useful if the system is used with one of the Smart Phone apps, or with the Rako RAH-Smart.

Page 12 of 20

Set the Power-Up Modes With the circuits responding to the Channel Controls, the Power-Up modes need to be set. When power is applied to a dimmer it can either fade up the lights, or leave them off – depending on the programming. This is an important setting as it tells the system what to do after a power cut. Generally, it is bad if all the lights come on after a power cut. Click on the Power-Up Mode drop down box at the top of the Channel Control screen. The list shows the different settings available to the dimmers. The default setting for a dimmer is 100%. This means that when power is applied to the dimmer it will turn the lights up to maximum. This is a very useful setting during installation & commissioning as it makes it easy to check that circuits are working. However – it is generally bad to use this as the final setting since it will cause lights to come on after supply interruptions. The most used options are: Last Scene: The dimmer will restore the same state that it was in before the power was removed. So – if the light was On before the power cut, it will come back on afterwards. If it was off before the cut, it will stay off. Off: Whatever the state of the light before the power cut, the light will stay off when the power is restored. The “Per Channel” option allows each dimmer in a room to have its own individual Power-Up setting if that is needed.

Hint: make sure the dimmers are really set to the required power-up setting. Rasoft does not send the dimmers the Power-Up setting unless the setting is manually selected from drop down menu. Just because it’s displaying “Last Scene” doesn’t mean that it has actually transmitted that to the dimmers. The Power-Up setting needs to be done in each room. Test the power up settings by switching off all the breakers, then switching back on.

Appendix 1: Adding Wireless Modules to system It is simple to add Wireless Modules to the system. Rako manufacture a wide range of such modules for a variety of Examples include: RDL250 RDL500 RDT500 RDL1200 RDF800 RDS800 RDDSI RDDALI RACUB RLED18-1ACI RLED36-3DCI RLED50-1DCV RLED90-3DCV RDC300

the

purposes.

Leading edge 250W dimmer Leading edge 500W dimmer Trailing edge 500W dimmer Leading edge 1200W dimmer 0-10V 800W dimmer 800W switch module DSI 800W dimmer DALI 800W dimmer curtain/blind controller 18w constant current dimming LED driver. 3 channel (RGB) 36w constant current dimming LED driver. 50w constant voltage dimming LED driver 3 channel (RGB) 90W constant voltage dimming LED driver. DC dimmer

Firstly, connect the Wireless Module to its load and connect it to the ac supply. If it is a lighting circuit, then applying power should bring the light onto full brightness. Assuming that the Wireless Module is still set to its factory settings: Check the circuit responds to a Wall Plate set to House 1, Room 4 (The factory Default).

“Ident” Wireless Module

Enter the name of the circuit in a spare channel. (Channel 4 in the example here).

The module must be allocated a Channel within a room in the Rasoft project file. Use the Channel Control screen. Select the room that the module is to be used in.

Hold a magnet steady against the side of the module next to the location of its internal LED.

Page 14 of 20

When the magnet is in correct location the LED will light up. Keep the magnet in position for a few seconds until the LED starts to blink in a steady rhythm. This indicates that the module is ready to be set to its correct channel.

Channel Ident Button

Return to the Channel Control screen and press the Ident Button for the modules chosen channel. As soon as this is done, the LED inside the dimmer module will stop blinking.

The Module is now addressed to the selected Room & Channel number

The Module will now behave exactly like the other (RAK4) channels on the system. It’s Scenes, Power Up settings, Ignore options etc are all programmed in exactly the same way.

Page 15 of 20

Appendix 2: Group Settings & Ignores Group setting allows dimmers to respond to commands from different rooms. Group Settings are typically used where a single area is split into two or three sub areas: Examples are Kitchen/Diner areas, Bedroom/Ensuite, Hallway/Landing. In the Rako systems, room numbers are either Group Masters of Group Members. Any room number that is a multiple of four can act as a Master for the following three room numbers. Thus Room 4 is a Master for Group Member rooms 5,6,7. Room 8 is Master for rooms 9,10,11 and so on. The Group Members can be programmed to respond to (or ignore) any of their group Master commands. Whole House Commands Room zero commands can be used to control every room in the house. The most common application is a “Whole House Off” commands which can be sent from a Wall Plate located by the main exit of the building. Group Example: Hallway – Room 9 Landing – Room 10 Each of these areas will have their own wall controller. A room 9 controller for the hallway and a room 10 controller for the landing. But it is also possible to fit room 8 controllers (at top & bottom of the stairs perhaps). The programming can be such that the room 8 controllers set lighting in both the landing and the hallway when climbing the stairway. Generally it is simpler if rooms are only given Group Member room numbers. (Room numbers 1,2,3 are also to be avoided. This is because the Group Master for these rooms is Room Zero). So number rooms as 5,6,7,9,10,11,13,14,15,17,18,19 etc. Avoid using Room numbers 1,2,3,4,8,12,16,20,24,28 etc. When allocating room numbers consider which rooms will benefit from being within the same group as each other. Typically a Bedroom and it’s Ensuite Bathroom may be grouped or Front External Lights could be grouped with Rear External Lighting.

Changing the Ignore Settings Select which Room Number to edit

Press the “Ignore Options” button

This warning is displayed. Press “OK”

4. The Ignore Options window is displayed

This shows which channel in the room is being set – (ALL channels in this instance).

Can tell the channels to ignore “Direct Commands” – that is commands from the channels own room. In this example none are selected, so all the Direct Commands are active. (It is rare to ignore direct commands). This button will send an Ident to the selected channel which will cause it to Flash . Use this to check that correct channel is being set Press to send Ignore Option settings to the dimmer (must be done for settings to take effect) Nothing ticked here so all Room zero commands received by the dimmers will be obeyed. Page 17 of 20

In this example All channels are being set to ignore group commands with the exception of the OFF command. An Off command from Group master will turn off the lights of this Group member

APPENDIX 3: Connecting Rasoft to a Programming Adapter Rasoft needs to be connected to the Rako system by a Programming Adapter. There are several modules that can be used: RAUSB - Most commonly used adapter used by installers for programming Wireless Systems RAV232 – Similar to RAUSB, but connects to PC via RS232 port. Wireless system programming only. RAV232+ - Bidirectional version of RAV232 which is normally used to interface between 3 rd party I/O devices (Crestron etc). Wireless system programming only. RAHSmart – Rako handheld remote controller that can be connected to PC via USB ARP-Bridge – Interface for Smart Phone apps. Can be used to program wireless systems. Connects to PC by Ethernet. WRE-Bridge – Interface for Smart Phone apps. Can be used to program Wired systems. Connects to PC by Ethernet. 232-Bridge – RS232 interface for Wired systems. Connects to PC by RS232.

1 - RAUSB Every Rako installer should have an RAUSB. Plug the RAUSB into PC USB port and run the RASOFT software.

Blue Light inside RAUSB blinks when it sends a message to wireless system

When the Rako Home screen appears go to Controls – Communication The USB (RAUSB) should already show as selected. Un-tick the Enable and AutoDetect boxes for Ethernet (RakoBridge) Then click OK. Quit the RASOFT program and restart it. The RASOFT project file should remember this setting from then on & not need further changes to the communication screen.

Page 18 of 20

2 - APR-Bridge Step 1: Connect the Bridge to a router. The APR-Bridge is supplied with an RJ45 network cable. Simply connect this to an unused port on a wireless router. Connect the Bridge power supply to a convenient ac socket and switch it on. A Blue light should flash continuously within the Bridge. Connect your PC to the same router, either by wireless network or by fixed Ethernet cable. Step 2: Set the Bridge to the same House ID number as your Rako system. Every RAKO wireless system has a House ID number between 1 and 255. It is necessary to tell the Bridge what house ID number has been set so that it talks to the correct house (and not the neighbours!). The RASOFT configuration file will tell you the House ID number. Alternatively, look at the DIP switches settings on the rear of the lighting control wall plates and decode the house ID number from those. To configure the Bridge House number: On a laptop, start the WEB Browser (e.g. Windows Internet Explorer). In the URL line type HTTP://RAKOBRIDGE and press Enter. If this fails, and if the PC is running the “Bonjour” service, then try typing RAKOBRIDGE.LOCAL The page below should be displayed. TIP: Some firewall programs will prevent access to the Bridge. Temporarily turning off the firewall will allow Bridge configuration to be done. Remember to re-enable the firewall afterwards

TIP:

Click on the Configuration Button. LOGIN to RAKOBRIDGE using Password The default User Name is admin The default password is microchip

Page 19 of 20

If it is not possible to make connection to the Bridge from the laptop, it could be due to IP addressing in the router. Try connecting the Bridge directly to the laptop using an RJ45 crossover cable. This will allow bridge to be configured. But, connect the bridge back onto the router afterwards in order to let the iphone work with it.

When successfully logged in, the screen below will be displayed:

House ID Number

Change the House ID number to match that of the RAKO system. Then press the Save Config button. This error message will probably appear after changing the configuration. This is normal. Just click OK

On the laptop, Run Rako Lighting RASOFT program. After a short delay the Rasoft start up screen will be displayed. Tip: Do not have any Rako USB or RS232 devices connected to your computer as these will interfere with the Bridge setup process Tip: It can take a minute or two from connecting the bridge to the router & switching it on, before RASOFT is able to talk to it .
