Continuous mode is not possible in sequence mode; in sequence mode, DC can be simulated by using long pulse widths.Note: Depending on the load and power dissipation, not all channels may operate at 1A simultaneous. The controller must maintain a safe power dissipation, so channel currents may be throttled.Each channel has an operating power limit of 10W, so the controller may throttle the power depending on the load that is connected.PulsedPulsed mode illumination is triggered by an external signal.Pulse widths and delay are available from 10 to 4,290,000000 microseconds and can be applied independently to any channel.Note: Trigger Input 1 and Trigger Input 2 are for Outputs 1 and 2 respectivelySequenceChannels settings are organized into events. The event could be considered a pre-set, or recipe, that stores the behavior when a trigger is received.Programming multiple events allows the controller to sequence through pre-determined recipes. Each external trigger edge will advance the sequence to the next event.Standard vs. SequencedStandard mode acts like a traditional strobe controller, where all channels that are enabled are triggered at the same time.Sequenced makes each trigger signal progress the saved sequence once event at a time.Trigger Input & OutputsSimplified Input Diagram (P2 pins 1 & 2)Outputs – Frame Start/Stop (P2 pins 3 & 4)Frame-start (Pin 3) is a 5V output trigger signal that occurs at the beginning of each channel pulse. This signal can be used to trigger an external device, or camera.For example: by using the frame-start signal, it is possible to synchronize a camera exposure to capture each channel as they flash in a sequence. This is useful inphotometric stereo applications where the camera needs to be carefully synchronized to capture multiple flashesFrame Stop (pin 4) -- Similar to frame-start except the stop signal begins at the end of each light pulse. This signal can be used to determine when the last channel pulse has ended and is useful for controlling system timing more accurately.Figure 5 Figure 6Software SetupDefault Ethernet SettingsThe Controller uses standard Ethernet protocol (TCP-IP and UDP) to communicate. The DCS control user interface can be used to communicate, or other software may be used to send data packets directly from the host to the controller.Table 5Setting ValueTypical Port Settings UDP, port 7777TCP, port 777DHCP Enabled by defaultDefault IP Address 192.168.0.5*Controller will use default IP if DHCP fails upon powerup, or if an Ethernet cable is not connectedUser Assigned IP Addresses User can assign a new IP address by sending acommand or entering a new IP address in the “managedevices” window of the GUI.If a user assigned IP address is used, the controller willnot begin using that IP address until the controllerpower is toggled.Figure 7 - Example PC settings This controller uses DHCP to automatically acquirean IP address. If directly to a PC Ethernet port, youwill need to set up the PC to use a static IP addressin the range of 192.168.0.xUser Interface (GUI)Figure 8 – Control GUITable 6 – Control GUI functionsSoftware Item DescriptionFile Save and Load recipes to the controllerDevice Additional options, clear saved settingsRefresh Re-scans the network for devicesConnect Connects to the device highlighted in the dropdownNetwork Configuration Edit and view network settings for the connected deviceEvents Contains all the channel settings (current, pulse width, delay, etc.)Add Event Creates a new blank event to be configured by the userDelete Event Removes the event from the listSave all events Commits the events to controller memory and saves changesLoad event sets the focused event as “active”Trigger Simulates a hardware trigger, activating the focused eventStop Stops all channels.

Event canthen be arranged in any orderSoftware UsageOverviewThe Ai DCS-400/800 software must connect to a device before it can be used. The Refresh button (see Figure 9) refreshes the list of available DCS-400/800 devices on the local network. Either select a device from the list or type an IP address (in dotted-quad, e.g. “XXX.XXX.XXX.XXX” format) and click connect.Figure 9: Software main window exampleSoftware ModesStandard ModeThe standard mode allows using a DCS-400 or DCS-800 like a traditional 4- or 8-channel controller. Operation in Standard Mode starts by putting the controller in Standard Mode and adding an Event (See Error! Reference source not found.).Adding an EventOnce an event is added, you can set configurations (current, channel mode, etc.) on each channel and they will be immediately reflected on the controller. Note that the event itself is not auto-saved: if you power down the controller the configuration will be lost unless you click “Save all Events”. The warning shown in Figure will inform you if you have unsaved edits.Figure 10Other events you add must be loaded with the Load Event button to be applied to the device. Loading an Event will set that Event active on the device, and it will be auto-loaded next time the device is powered on. If no Event is loaded when the device is power cycled, it will load the first available saved Event. Saving channel configurations as an Event allows you to easily recall the configurations later, much like the Profiles in Advanced illumination’s DCS-100 and DCS-103 controllers.Sequenced ModeSequenced mode allows the controller to automatically cycle through a predefined series of Events with a hardware trigger (currently only Trigger Input 1). This allows the controller to, for example, flash alternate sides of a right light with only one a continual stream of trigger pulses and no further input from the software/SDK.EventsCreating an Event is the same as in Standard Mode, except for two points:1.Event changes are not immediately updated on the device.2.An Event cannot be loaded directly while in Sequenced Mode, only Sequences can.SequencesA Sequence is, at its simplest, a list of Events. When a Sequence is loaded, a hardware trigger causes the controller to start the first Event in the list, the next trigger starts the next event, and so on. When the last Event in the Sequence is reached, it starts over from the first Event.Clicking “Add Sequence” adds a new sequence, which appears inline below the other sequences in the list. On any Sequence, you can select an Event from the dropdown in the Sequence and click “Add selected event” to add that event to the Sequence. You can have multiple of the same Event in the Sequence; however, you are limited to 10 Events per sequence.Once you have a Sequence defined, click “Save sequences” to save all defined Sequences to the controller. You can then make load a Sequence on the controller by clicking “Set as active” on a sequence. The “Run sequence” button allows you to simulate a trigger pulse to ensure that sequence is working as intended. Be aware that this button sends an HTTP POST message to the controller, so there will be network delay between the click and the pulse.Network ConfigurationNetwork Configurations are viewed by clicking the “Network Configuration” button on the main window when connected to a device. Network Configurations opens in its own window, as shown in Figure 7 below.Figure 73: Network Configuration example in DHCP ModeStatic IP configurationA static IP address is set by entering an IP address, subnet mask, and Gateway address in the boxes provided. Note that the window displays the current value of all settings, even if it’s using DHCP. Settings are saved by clicking the “Save Settings” button. If settings are saved unchanged from the values displayed from DHCP, then the device is assigned a static IP address configuration matching those values.Resetting to DHCPNetwork configuration can be reset back to DHCP mode by clicking the red text “Reset to DHCP” button, which will replace the green DHCP message when the device is using a static address. The device should then be power cycled for it to use its new settings.Web Browser User InterfaceEntering the device IP address into a web browser (Chrome, Firefox, Edge) will open the controller web browser.Figure 14Software Command and Control InterfaceCommand StructureThe DCS400/800 uses an SCPI-like interface where commands are a series of readable strings with parameters separated by commas. The strings must be terminated by a semicolon (‘;’) for proper operation.Commands can be sent in an ASCII format by specifying the IP Address and correct port number for either TCP/IP or UDP.Commands with a parameterCommands that require a parameter have it separated by a comma.Example: “SET:PULSE:WIDTH:CHANNEL1, 100;”Where “SET:PULSE:WIDTH:CHANNEL1,” is the command and “100” is the parameter. Commands without a parameterIf the command has no parameter, the command simply ends with a semicolon.Example: “*IDN?;”Commands are case sensitive, and must be entered exactly as shownCommand TableTable 7COMMAND DESCRIPTION RETURNSSET:CURRENT:CHANNELc,nnnn;Sets the current inmilliampsc = 1 - 8 (channelnumber)nnnn= 0-8000 (strobe)SET:PULSE:WIDTH:CHANNELc,nnnn;Sets the pulsewidth in usecc = 1 - 8 (channel number)nnnn = 0 – 4290000000 (us)INFO: Channel “c” pulse width set to “nnnn” usSET:PULSE:DELAY:CHANNELc,nnnn;Sets the pulse delay inusecc = 1 - 8 (channel number)nnnn = 0– 4290000000 (us)INFO: Channel “c” pulsedelay set to “n”microseconds.PULSE:CHANNELc;Software triggers thechannelc = 1-8SET:MODE, [SEQUENCED][STANDARD];Sets the controller ineither sequence (mode 0) orstandard (mode 1)Note: can use the number 0or 1 instead of “sequenced”or “standard” in thecommandINFO: Set mode to 'n'SAVE:CONFIG,[1-10]Saves the active channelsettings to the given eventnumber (standard mode only)*IDN?;Gets device information: firmware, hardware, etc..Advanced illumination“DCS-100: (fw version, hw version)”*CHANNEL:INFO?;Gets device channelinformationSET:IP:ADDRESS,xxx;Sets static IP address.Xxx = IP address in dotted-quad format(XXX.XXX.XXX.XXX)INFO: Set IP address to XXX.XXX.XXX.XXX.
