Last edited 18/1/2024

To be able to use the FCU you will need to join MERG. so you can get the program install files.

• https://merg.org.uk/
• You need a login and password to access the site.
• Link to the page here

Stage 1

• Start the FCU program and have the module connected via a usb lead.
• To add the module to the FCU you will first need to use the Arduino Ide to send a message via the serial monitor. Type "r" in the message window and press enter on the computer keyboard. This is called "renegotiate"

Stage 2

• You will then see a new window appear from the FCU programme.
• Here you can see I have the Node Name as Node 1.
• The Node Number is set as 256.
• Node Type has picked up the Node Type from the 7 digit name given in the main sketch.

• Click the Ok button and you will see the module appear

Stage 3

• Next you need to go to the Nodes tab and scroll down to Read Properities
• Next select the selected node there is a short cut you could use ALT + S

• Here you can see the properties of the node.
• Click close

Stage 4

• In the Nodes Tab and click on the read NVs or Alt + R
• In the nodes Tab select update NVs...

• Choose what you want the 6 inputs Node Variables to use from the 5 possible choices. 0 is the default in generic mode of the FCU
• I have set them all to 1 for this example.

• Now you will see the Node Variables have been changed.

Stage 5

• Now I have ground out the pins A0 to A5 to create some events.

You are now ready to teach these events to other Nodes On your Bus.
