What is System2 Air?
System2 is our new generation of model railway accessory bus products that feature our V-Port
protocol (virtual port) and can address up to 60,000 devices. You can scale an installation from a
single Servo-8 Controller (8 V-ports) right up to a huge layout as your needs grow. Flexibility is baked
in and as we announce new modules that will work right alongside other System2 modules.
The “Air” in System2 refers to how you configure the system. It’s done wirelessly using Wi-Fi. This
means you can configure a device using your PC, tablet or phone and replaces the need for buttons,
flashing lights and extension cables to reach under baseboard locations.
We use Wi-Fi for configuration and a CAN network for data. This offers high speed, low latency and
above all else reliability. You can even shut down the Wi-Fi network when your configuration is
complete making your system secure and robust. It’s not required for operation at all.
MQTT support built right in. Using Wi-Fi and MQTT you can optionally configure the device for
wireless operation and avoid the need to cable in a CAN wired network altogether. Our MQTT
implementation supports two modes, Native for peer to peer communication and JMRI where we
delegate control authority to your JMRI installation.
Software for all System2 Air modules can be updated over the air if your network allows Internet
access. A single button push is all that’s needed to download and install the latest version. This
means as new ideas and features are introduced everyone gets to benefit from them. You can even
see the changes that have been introduced since your last update and choose whether to install or
not. You won’t get nagging reminders to update. It’s flexible and entirely up to you when or if you
decide to do it.
System2 has been real world tested on some of the largest exhibition model railway layouts in the
UK for over a year before launching, so you can be confident it’s fit for your needs and fit for
purpose.
Each of our System2 boards has the administrative core baked in. You can connect to any board’s
admin web page and from there manage your entire network. There’s no central point of control (or
failure) as they are all peers in their own right.
We use standard web protocols for configuration so that your browser can connect and perform all
administrative tasks without requiring any special apps and app permissions. This leaves you in
control of your network.
System2 Air, for the smallest to the largest layouts and everything in between.
In order to use System2 you’ll need a Wi-Fi router configured for DHCP with optional Internet access.
This is the standard router configuration as supplied by your Internet Service Provider.
Designed and manufactured in Cheshire, England.

How to use this document
Treat this guide as a reference. All settings are documented and examples given where appropriate.
It is designed to accompany the System2 Air –RFID Introduction video that will demonstrate all the
functions and use cases.

System2 Dual RFID Reader Module
Introduction
The RFID quad display module is a four channel four digit seven
segment display driver intended to display RFID data generated by
the S2 RFID reader via a System2 network. It features a Wi-Fi based
intuitive configuration from the comfort of your PC, tablet or phone.
You assign each reader/writer to a vPort and the RFID tags read will
be directed there.
RFID tags will be displayed in real-time for up to four channels (4
vPorts). This is the complimentary display for the S2 RFID dual
reader.
You may also need:
12 Volt DC regulated power supply.
o500 mA minimum
Network cable (twisted pair).
oTelephone cable
oAlarm cable
oSuch as CW1109B/Y supplied by CPC/Farnell .
See website for cable links. Non twisted pair
cable is OK for testing purposes, not for
installation.
An accompanying RFID Dual reader.
To use the network features of this board you will require:
A Wi-Fi Router that is configured for:
oDHCP (default enabled on most routers)
oAn active internet connection (only required for software updates).
A current browser that supports HTML5.
To use the MQTT features of this board you require:
An MQTT broker installed on your local network (see installation video on our System2
website).
An optional JMRI installation if JMRI is to be used.
This is a 12 Volt device and
should be connected to a
minimum of 2 Amp
regulated power supply.
MegaPoints Controllers use
static sensitive components
that must be handled with
care.
Avoid touching any
components or the circuit
printed on the bottom of
the board.
Avoid placing the board on
any metallic surfaces
including track.
DO NOT connect any part
of this device directly to
your track bus.

What’s included
Refer to the picture below.
Included with the S2 RFID Quad Display driver are:
4 x 4 digit seven segment displays (blue)
4 x display connector cables
Connecting up
Connect the displays (blue) to each display connector on the System2 board (white). Ensure the top
of the connector (S2 black marked GND) matches the GND connector pin on the blue.
MegaPoints Controllers System2 RFID Quad Display Driver Revision 1
megapointscontrollers.co.uk Page 7
Connect each board to a 12 Volt regulated power supply, minimum ½ A per device.
Connect the network cable to the two screw terminals. Observe the ‘H’ and ‘L’ terminals.
Ensure all the ‘H’ and ‘L’ wires connect to each other respectively.

Getting to your readers admin web page
Navigate to the RFID Quad Display admin page by either connecting to the IP address assigned by
your network or navigating to the device name. In the screen image below the device name is
“rfidd-45193c”. From your PC, Mac or tablet enter http://rfidd-45193c “ or
http://rfidd-45193c.local”.
If you have existing System2 products configured and are using the wired CAN bus you can use the
“Locate Board” feature to deteremine the IP address. Id correctly cabled it will appear in the Status
Log along with any other boards on the network. In the example below the RFID Display board has
no IP address (0.0.0.0) as it is new and not registered with your network.
Press the “Share WiFi Credentials” button on any System2 board that is configured and after a few
seconds you’ll see the new board appear with an IP address.
Clicking on the blue IP address for the Panel Controller is usually the quickest way to get to the main
admin web page. This technique works for all System2 boards.

vPorts
There are four vPorts that data will be received on in the second column. Each vPort must match the
vPort for the RFID dual reader. As a tag is read by the corresponding reader it will display on the
appropriate seven segment display.
Clear vPorts
The clear vPorts default to 1-4. These are regular vPorts (normally a block detector or point position
indicator) that can be used to clear a display. The “Clear State” buttons can be toggled by clicking to
either a “0” or “1” indicating ON or occupied and OFF or clear.
When a matching vPort is triggered and matches the clear state the corresponding RFID seven
segment display will clear.
Set these to “0” to disable the feature.

Example: Clearing the previous display
We can arrange to clear a previous display once the next reader along has read a tag. This allows you
to clear a display once the loco has left the section.
Refer to the image above. Display 1 will clear when reader 2 reads a valid tag.
Set the RFID reader 2 State vPort to State “1”
and vPort “1”(right image). This will send an
occupied signal to vPort 1 when the reader
activates.
On the RFID Display
(left image) set the
Display 1 Clear vPort
to “1”and the Clear
State to “1”. This
will clear display 1
then the vPort 1
receives an active
flag.
Example: Manually clearing a display
In this example we will manually clear displays. You can do this in conjunction with the previous
example or as an isolated use case.
