SMART SHOW AirPixel Mini II Installation & Use

Introduction

AirPixel-Mini-II is a Wifi ArtNet/sACN(E1.31) to WS281x/SK6812/UCS (NRZ) driver interface. It is capable of receiving up to 4 DMX
universes, with up to 512 channels per universe. The data is then converted into continuous NRZ data streams that will appear at the output.
There is a three screw terminal connection for Ground, DataOut, and Power (5-24V). The device sends 4 universes consecutively on its data
output. Network connection can be made by utilising a special Join-A-Network mode. Device IP, ArtNet/sACN, Pixel Test and settings are
adjustable directly from a second browser interface once the Wireless Network Connection has been made. Connection status is shown with a
bi-coloured LED. Product Firmware updates can be sent over-the-air.

Unsuccessful network Connection : Equal On/Off slow flashing RED (after 60 seconds of failed attempts)
Access-Point Connection
On first power-up (when the AirPixel has not been set up before), it will appear as an Access Point. If you check your list of wireless network
connections you will find the device in the list as 'Airpixel xxyy' (where xxyy are the last two octets of the device mac). The AirPixels status
LED will be slowly flashing RED. On your PC, select the device from the list of wireless network connections and enter 'smartshow' for the
password. Once connected the AirPixels LED will do a repeating slow double flash.

'Join A Network' Configuration Page
To access the 'Join A Network' configuration page, type into the URL bar '192.168.4.1' and press return, the configuration interface should
appear as follows:
Network SSID & Password Settings
Network SSID: Enter the name (SSID) of the wireless router for the network you wish to join
Network PASS: Enter the password (PASS) for the above network.
[Save SSID & Password] The above SSID and Password will be saved so that next time the device reboots, the connection will be
made automatically (unless the Network/Pass cannot be verified)
[Connect to Network] *READ DEVICE SETTINGS BELOW BEFORE PRESSING CONNECT* This will allow the device to connect
to the Network as specified above, the device will close down its Access-Point ('Join-A-Network') connection and restart as a network
client/node. While the device is making the network connection the LED will show a medium RED flash. When the device's LED
changes to a solid BLUE it confirms the connection to your chosen wireless Network.
Device Settings & IP Configuration
Device IP Address: It is possible to set the IP Address of the AirPixel to almost any value. Many ArtNet devices will use standard IP
addresses of 10.x.x.x or 2.x.x.x, only values of 0-254 can used, 255 is not allowed.
Note : If you change this IP address, the new IP address will be the one that will allow you access to this configuration page next
time you reboot. Also take care to only change to an IP address that you actually have access to.
Device SubNetMask: Normally this should be left at 255.255.255.0, which will cover most applications.
[Save Device Settings] Saving the configuration will write the Device IP and SubNetMask values to the AirPixels internal memory,
so on next power-up the new settings will be used.
Resuming Network Connection
Once the device has connected to your chosen Network (Solid BLUE LED), then you should disconnect your Laptop/PC from the AirPixels AP-
Mode (it might automatically do this anyway), and then manually connect your Laptop/PC back to your existing Network (Same SSID as
above)
[Laptop/PC] <--- wifi ---> [ROUTER] <--- wifi
Note : If the device's LED stays flashing medium speed RED then you have not been able to connect to your desired network (you may
have entered the SSID & PASS incorrectly). If you cycle the power to the device you will start in AP mode once again, the device will do this
until a confirmed network connection has been made.
Browser Configuration Mode
To access the browser configuration page, type into the URL bar the Network IP Address (this will be default value '192.168.1.200' unless
you have changed it from within the 'Join-a-Network' page) and press return. Note : Access to the Browser Configuration page is only
available when ArtNet data is NOT streaming to the device over the network, therefore access can only be granted when the Devices LED is
SOLID BLUE. The configuration interface should appear as follows:
Network
Connection: The page should announce the currently connected network name as 'Connected to..'. Pressing [Delete] will remove
the details of the currently connected network from the device, this may be required if you want to move from one wireless router to
another. The next time you power up the device it will go into Access-Point mode again which will allow a new SSID & PASS to be
entered (see Join-A-Network)
IP Address: The required Device IP. Note if you change this you also need to change the URL IP to access the device again
SubNetMask: Normally this should be left at 255.255.255.0, which will cover most applications.
MAC Address: This is not adjustable and is a unique number created when the device was manufactured.
[Save] New IP configuration will not take place until the AirPixel has its power cycled (or by pressing [Reboot]). Saving the
configuration will write the Device IP and SubNetMask values to the AirPixels internal memory. On the next power-up the new
settings will be used.
DMX Protocol Set-Up
Protocol: Select either ArtNet or sACN (E1.31) to match the DMX Data Protocol coming from the host application
Starting Universe: These values can be configured to match the requirements of your system. There are a total of 32,768
universes for ArtNet III, and 32,999 for sACN
ArtNet: Net: Range 0-127 SubNet: Range 0-15 Universe: Range 0-15 – sACN Universe: Range 1-32999
[SAVE]: New settings will take immediate effect after they are saved.
