[[ru:Настройка Light Stream Converter]] [[en:Light Stream Converter Setup]]
A converter is a device that receives a network signal from the computer and distributes it to fixtures through its ports. To make it work on site, it needs to be configured: set the network address, port mode, pixel chip type, and universe numbers. All of this is done directly from Light Stream, over the network, without any separate utilities.

This article is about configuring the '''physical device itself'''. The converter's parameters '''inside the project''' (which address and protocol to send data to, how many ports and universes are described in the project) are a different window, described in the article [[Параметры Light Stream Converter]]. The device settings and the project settings must match: if they diverge, the program will keep sending data correctly, but the fixtures will stay dark.

Configuration is done over the network using broadcast requests. The computer and the converter must be connected to the same network, and the computer's network adapter must be on the same subnet as the device.

== Finding devices on the network ==

It all starts with the '''Art-Net Node Discovery''' window. It can be opened in two ways:

* in the '''Fixtures''' window — the magnifying glass button ('''Search''') on the bottom panel, next to the '''Add Device''' button;

* in the program settings, '''Network''' section — the '''Search''' button (see [[Settings]]).

Workflow:

# In the '''Network Device''' list, select the network adapter the converters are connected to. The choice is remembered and offered again the next time the window is opened.

# Click '''Search'''. While the network is being polled, a progress indicator runs at the bottom; the search takes a couple of seconds.

# Devices found appear in the list on the left: the device's '''IP''' and '''Name'''.

# Select a row — information about the selected device appears on the right: the long and short name, IP address, device report (''Node report''), firmware version, ESTA and OEM codes, MAC address. The device report shows which mode the ports are currently working in and which chip is selected.

A device report looks roughly like this: <code>#0001[0035] UCS1903(High,340)Tb=125,T0=30,T1=100,Tr=290</code>. Here <code>UCS1903</code> is the selected chip, and <code>340</code> is the port mode (340 pixels per port).

Good to know:

* For the duration of the search, the program stops sending Art-Net and turns it back on once the search finishes. If the lights on site go dark during configuration, that's normal — they will come back.

* The '''Ping''' button makes the selected device respond: the real converter blinks its indicators. This makes it easier to tell which box in the cabinet corresponds to the found IP. The button only works for Light Stream devices.

* The '''Settings''' button opens the configuration window for the selected device. It is only available for Light Stream converters: devices from other manufacturers and the '''Light Stream Player''' have no settings here.

* If the list is empty, check that you selected the right network adapter and that it is on the same subnet as the converter.

== Adding a found device to the project ==

The '''Add Selected Nodes''' button adds the checked devices to the project along with their real settings. You can select several rows at once.

* A found '''Light Stream Player''' is added to the project as a player, with its IP address.

* A found converter is added as a converter: with the device's name and IP address, its starting universe, and the actual number of ports the device has. If the ports are working in 1024-channel mode, the program accounts for the fact that each port takes up two universes.

This is the fastest way to describe already-configured equipment in the project: there's no need to manually cross-check addresses and universes. After adding, all that's left is to patch fixtures to ports — see [[Патчинг приборов]].

Adding can be undone with ''Ctrl+Z'', like any other action in the project.

== The "Controller Settings" window ==

The window is opened with the '''Settings''' button in the search window and is divided into four parts:

* '''General Settings''' — network address, device name, port mode, and chip;

* '''Ports''' — a table of universes per port;

* '''Information''' — what the device currently reports about itself;

* '''Send Art-Net Macro''' — a service field for tech support commands.

Changes are only sent to the device when you click the corresponding '''Set''' button. Just typing a value into a field is not enough.

=== IP address and subnet mask ===

# Enter the desired '''IP Address''' and '''Mask'''.

# Click '''Set IP'''.

# Confirm the action in the '''Change IP?''' window.

# On success, the message '''IP set successfully''' appears, and the list of found devices refreshes automatically.

After changing the device's address, be sure to set the same address for the converter in the project — in the '''IP Address''' field in the '''Properties''' window (see [[Параметры Light Stream Converter]]). Otherwise the program will keep sending data to the old address.

If the computer and the converter end up on different subnets, the device may disappear from the search after the address change — bring the computer's network adapter onto the new subnet and search again.

=== Device name ===

The '''Full Name''' field and the '''Set''' button next to it write the name into the converter. The name is visible in the list of found devices and in Art-Net reports, so meaningful names ("Facade North", "Roof") greatly simplify further work on a site with a dozen identical boxes.

=== Port mode and chip ===

The '''Port Mode''' list sets how the device's ports work:

{| class="wikitable"
! Value !! What it means
|-
| '''DMX 512''' || Regular DMX: 512 channels, one universe per port
|-
| '''DMX 1024HS''' || DMX with double the channel count: 1024 channels, two universes per port
|-
| '''SPI 170 Pix''' || Pixel mode, up to 170 pixels per port
|-
| '''SPI 340 Pix''' || Pixel mode, up to 340 pixels per port
|-
| '''SPI 680 Pix''' || Pixel mode, up to 680 pixels per port
|}

The '''Chip''' list only appears in '''SPI''' modes — DMX ports have no chip. It selects the type of the driver IC used by the LED strip or pixel module: '''GS8206''', '''WS2811''', '''WS2811L''', '''WS2812''', '''WS2814''', '''WS2818''', '''SK6812''', '''UCS1903''', '''UCS8903''', '''TM1803''', '''TM1914'''. The value must match what is actually installed in the connected line, otherwise the pixels will flicker randomly, glow the wrong color, or not light up at all.

To apply the mode and chip, click the '''Set''' button to the right of the '''Port Mode''' list — it sends both settings at once. The device does not switch over instantly: the cursor will turn into an hourglass for a few seconds, after which the program re-reads the converter's state and shows the new report in '''Information'''. Wait for it to finish without closing the window.

The mode and chip are set for the whole device at once, for all of its ports.

=== Mode of an individual port ===

An individual port's mode is assigned in the '''Ports''' table: '''right-clicking''' a port row opens a menu with the items '''DMX IN''', '''DMX OUT''', '''RDM''', and '''SPI'''. After you make a selection, the program reports '''Port mode set successfully''' and refreshes the device data.

* '''DMX IN''' — the port receives DMX from a third-party console.

* '''DMX OUT''' — the port sends DMX to fixtures.

* '''RDM''' — the port works with feedback over the RDM protocol.

* '''SPI''' — the port drives a pixel line.

This makes it convenient, for example, to leave one port for receiving external DMX while using the rest as outputs.

=== Port universes ===

The '''Ports''' table shows which universes are assigned to the ports directly on the device.

{| class="wikitable"
! Column !! What it shows
|-
| '''Short Name''' || The port name as reported by the device. If a port takes up two universes, it will have two rows with the same name
|-
| '''Universe''' || The overall universe number, from 0 to 32767. This is the number you compare against the port universes in the project
|-
| '''Net / Sub / Universe''' || The same number broken down into three parts per the Art-Net standard: '''Net''' (0–127), '''Sub''' (0–15), and '''Universe''' (0–15)
|}

Both representations are linked: change the overall number and the three fields recalculate, and vice versa. The overall number is computed as ''Net × 256 + Sub × 16 + Universe''. Set it whichever way is more convenient for you.

Buttons below the table:

* '''Select All''' — selects all rows.

* '''Edit Selected''' — asks for a '''Starting Universe''' and numbers the selected rows sequentially from it. The fastest way to lay out universes in order.

* '''Set''' — writes the changes to the device. Art-Net sending stops while writing is in progress. When it finishes, the program re-reads the device and verifies the result: if everything was written, '''Save successful''' appears; if not, '''Save error'''.

The universes written to the device must match the converter's port universes in the project. In the project they are not set one by one: instead you specify the '''Starting Universe''' and '''Universes per Port''', and the rest are calculated in order. The simplest approach is to number the device's universes sequentially with the '''Edit Selected''' button, and set the same starting universe in the project.

=== Information ===

The '''Information''' section shows what the device currently reports about itself: '''Full Name''', '''Short Name''', '''IP Address''', '''MAC''', '''Status''' (device report), firmware '''Version''', '''ESTA''' and '''OEM''' codes. These fields are read-only and refresh after every successful settings write — they're convenient for checking that changes were actually applied.

=== Service elements ===

The '''Data''' field and the '''Send Macro''' button in the '''Send Art-Net Macro''' section send a service command to the device. Use them only on the instructions of technical support. The '''Reset Settings''' button in this window is inactive.

== Steps to set up a new converter ==

# Connect the converter to the network and set the computer's address to the same subnet.

# Open '''Art-Net Node Discovery''', select the network adapter, and click '''Search'''.

# Find the device you need in the list, and use the '''Ping''' button to confirm it's the one responding.

# Click '''Settings''' and set the device's working '''IP Address''' and '''Mask'''.

# Set the '''Full Name''' you'll use to recognize the device.

# Select the '''Port Mode''' and, for '''SPI''' modes, the '''Chip'''. Click '''Set''' and wait for the device to switch over.

# In the '''Ports''' table, number the universes and click '''Set'''.

# Close the settings window, repeat the '''Search''', and add the device to the project with the '''Add Selected Nodes''' button.

# Check the converter's parameters in the project: '''IP Address''', '''Starting Universe''', '''Number of Ports''', '''Universes per Port''', and '''Controller Type''' ('''SPI''' for pixel lines).

# Patch the fixtures to ports and turn on '''Art-Net'''.

== If something goes wrong ==

'''The search finds nothing.''' Check the selected network adapter, the physical connection, and that the computer's address is on the same subnet as the converter. Some network switches and Wi-Fi adapters don't pass broadcast requests through — connect over a cable.

'''The device disappeared after changing the IP.''' The new address ended up on a different subnet. Bring the computer's network adapter address onto the new subnet and search again.

'''Save error when writing universes.''' The device didn't confirm the changes. Retry the write; if the error persists, check the connection to the device with the '''Ping''' button and make sure no one else is accessing the converter while it's being written to.

'''The "Ping" and "Settings" buttons are unavailable.''' Either more than one device is selected in the list, or the selected device is from another manufacturer, or it's a '''Light Stream Player'''. Settings in this window are only available for Light Stream converters.

'''The mode and chip weren't applied.''' The device needs a few seconds to switch over. Don't close the window until the waiting cursor disappears, and check the report in the '''Information''' section.

'''No light appeared on site.''' Cross-check the device settings against the converter's parameters in the project: IP address, universe numbers, port mode. A pixel line needs '''SPI''' mode both on the device and in the project (the '''Controller Type''' parameter), otherwise the image will shift at universe boundaries.

'''The pixels glow the wrong colors or flicker.''' The '''Chip''' type doesn't match what's actually installed in the line.
