1. Null Pixels Zigzag Reverse and Grouping may be used in any combination You could for example have a string that has 4 null pixels is lit in groups of 5 zigzags every 25 and is driven from the far end GF This command is used to load a new firmware file over the network Follow this procedure to update the controller firmware via the network Not only does this eliminate the need for a dedicated programmer it allows updating the firmware of controllers that are installed in locations where physical access to the controller is difficult The firmware updater is a small program written in Python that sends the firmware file to the E682 controllers on your LAN Please follow these steps to do an update 1 Download and install Python version 2 6 on your PC As of July 2012 this link is good if there s an issue please Google python 2 6 download for a current link http www python org ftp python 2 6 6 python 2 6 6 msi This will download a file named python 2 6 6 msi Double click this file to install Python Accept all of the defaults during the installation This will install Python into a folder named Python26 in the root of your C drive C Python26 2 Download the firmware loader program from sandevices com fwloader_1_O py and move it into the C python26 folder Keep the python26 folder open on your desktop Steps 1 and 2 only2. CO ey Bg The DMX command sets the starting DMX address for the pixels attached to this cluster Only the start address is specified All pixels on the cluster every pixel in every string will then be assigned sequential DMX addresses beginning with the specified starting address In some cases th nding DMX address will be in a different socket universe but this is allowed The number of DMX addresses used by a cluster will be equal to number of strings X number of pixels per string X 3 Starting DMX addresses ar ntered in the form of s ccc that s a socket number 1 6 followed by a channel number 1 510 In other words if we enter our DMX command as DMX 1 2 151 what we are saying is that the DMX addresses for cluster 1 will begin with the 15lst channel of the DMX universe assigned to our 2na socket Now if you happen to have assigned sockets 1 4 to DMX universes 1 4 then slot and DMX universe number will in fact be one and the same Just to be clear you first assign DMX universes to SOCKETS then you assign channels within those SOCKETS to CLUSTERS Ending DMX addresses for a cluster are displayed but you can t change that value It s possible for DMX address ranges to overlap this may or may not be intended DMX n s ccc Defines starting DMX address for lst pixel of cluster n as the universe assigned to socket x channel CCC The DMX ending
3. 7 flashes IP address was forced to DHCP by the pushbutton but no DHCP server responded so our IP address was set to 169 254 74 73 Note that for blink codes 5 and 7 there will be about a 10 second delay before the cod is flashed During this time the system is waiting for a DHCP server After this flash code the red LED will come on and stay on indicating that the E682 s web server is running The firmware as shipped will default to an initial static IP address of 192 168 1 206 If an IP address other than this has been assigned at the factory it will be indicated by a sticker on the CPU chip If this is incompatible with your network see instructions below to force the use of DHCP at startup Forcing a Specific IP Mode at Startup It is possible to over ride the default network configuration if necessary using the on board program pushbutton At power up or after restarting by pressing the RESET button press and hold the program button After a few seconds the red and green status LEDs will begin flashing on and off together at a rate of one flash per second To override release the PROGRAM button After 1 flash to force the web server to start without affecting the network mode Not normally required since the E682 is almost always configured to have the web server running continuously After 2 flashes to bring up the web server and force the IP mode to be static
4. After 3 flashes to bring up the web server and force the IP mode to be DHCP These functions are in place to allow you to communicate with your E682 via a web browser regardless of the state it was in For example you may have your E682 configured for a static IP address but you ve moved it to a new network where that address isn t available Or perhaps it s configured for a static IP but you don t know what that IP address is Or perhaps in your configuration you have disabled the web server Using the over ride option at startup you can force your E682 to enable its web server and you can force it to get an address via DHCP or force it to the static IP address of 169 254 74 73 Then can you access its configuration page with your browser change the configuration and save it For the initial setup of an E682 connect the E682 to an unused wired LAN port on your router You can also use an available port on an Ethernet switch if your network configuration includes switches Basically you want the E682 on the same network that your PC is on Once that s done and the E682 is powered up try accessing the E682 s web page by typing 192 168 1 206 into the address bar of your web browser If your network uses 192 168 1 X addresses the E682 s web page should appear If it doesn t then the most likely cause is that your network uses some other address range Most Linksys routers will use 192 1
5. The following group of commands set the configuration data displayed in the Global Configuration portion of the web page Every configuration page has an area to store a static IP address Even if you set the network mode to DHCP you can still save static information This eliminates the need to re enter the static information every time you switch from DHCP to static There are 4 entries here Static IP Subnet Mask Gateway and DNS Server Usually DNS and Gateway will be the same the address of your router In most small LANs this will be either 192 168 0 1 or 192 168 1 1 Subnet mask in a 192 LAN will be 255 255 255 0 or just 24 The commands are IP a b c d where a b c d is any valid IP address SUBNET a b c d or SUBNET n where a b c d is any valid subnet mask value or n is the size of the subnet in bits GATEWAY a b c d where a b c d is any valid internet address Usually the address of your router DNS a b c d where a b c d is any valid internet address Usually the address of your router If you are only using DHCP not recommended you can leave the static IP areas unused Network addressing static or DHCP IP is only needed to access the E682 s configuration page with a web browser Once configured no IP address is needed for normal operation The Default IP Mode Web Server Mode No Data Timeout and Test Pattern commands affect what happens when the system starts up DEFAULT n

7. can reduce the DMX channel count significantly allowing a single E682 to control more pixels For example if you are lighting a single display element such as a wreath or mini tree you may want to use pixels to be able to select any color but you may not need control of every pixel on that item You might group the entire string as lone group thus being able to light that display element with only 3 DMX channels GROUP n aaa Defines the pixel grouping for strings in cluster n to be aaa pixels Example GROUP 1 1 says that all pixels in cluster 1 will be controlled individually String Length is calculated automatically by multiplying pixels X grouping he RGB command defines the order in which the 3 color channels are assigned to the ixels in a given cluster Most pixels use the same sequence that the name RGB would mply RED first followed by GREEN then BLUE Some pixels however assign their color hannels in a different order BGR is fairly common To cover all possibilities the GB command lets you define the RGB pixel order of a cluster s strings to be any of the 6 ossible combinations using a number from 0 to 5 The numeric codes and the sequence hey assign is as follows O RGB 1 RBG 2 GRB 3 GBR 4 BRG and 5 BGR RGB n a Defines the pixel color order for strings in group n RGB 1 5 would define cluster 1 pixels to be BGR
8. DATA DATA CLOCK DATA GROUND GROUND V V often not used The pinout to connect to a standard wired DMX XLR connector would be GROUND XLR Pin 1 signal ground DATA XLR Pin 2 datat DATA XLR Pin 3 data V not used When a cluster is configured for Native DMX each output of that cluster becomes a separate DMX universe output The channel numbers corresponding to each string are mapped to the first n channels of that output where n is the defined string length X 3 For example if Cluster 4 is defined as chip type Native DMX and we set cluster 4 to have 2 String s of length 170 pixels then outputs 4 1 and 4 2 will each output a 510 slot DMX universe For best results the cluster s being used for DMX should have the Balanced Output jumpers in place so that the output becomes a standard 2 wire balanced DMX signal This feature can also be used in conjunction with a balanced receiver located at the pixel string to drive 3 wire pixels over much longer distances than are achievable with the standard unbalanced pixel data signal This is limited to 3 wire pixels because th CLOCK signal is not available in this mode Please note that this type of output will not have the full drive capability of purpose built DMX hardware This feature is intended primarily to drive limited numbers of DMX fixtures over relatively short distances say tens to hundreds of feet rather than t
9. DMX addresses are assigned by cluster In other words you tell the board what the DMX address will be for the 1st pixel on a cluster and all of the other pixels in that cluster will follow in order In most cases the capabilities of the board will be more than adequate but bear in mind that not every configuration is possible For example if you want to use 5 volt 6803s 12 volt 6803s 5 volt 2801s 5 volt 1804s and 5 volt GE pixels all at the same time you amp a an t do it because that s 5 different pixel types each would require its own cluster nd we only have 4 clusters available Another example would be a configuration consisting of 5 volt 2801s 12 volt 1804s 12 volt TLS3001s and 12 volt 2801s That s only 4 different types but that configuration won t work because the pixel voltages are split as 2 clusters each and our example requires 3 clusters at 12 volts and 1 cluster at 5 volts which can t be done Some guidelines on planning the pixel configuration Plan on connecting pixel strings in order beginning with the first available connection with the proper voltage Strings that must light sequentially in other words typically all of the strings in a given display element such as a mega tree should be plugged into consecutive connectors possibly spanning more than one cluster lso please keep in mind that a single E682 can control a maxi
10. address is automatically calculated and cannot be changed with a command It is a function of the starting address the number of strings and the number of pixels per string The reverse command defines which if any of the strings in this cluster are reversed A reversed string is one where the pixel nearest the controller is considered to be the last pixel in the string and the farthest away pixel is the first It is used when it is more convenient to attach a pixel string to the controller at what would normally be the far end Although reverse is specified on a per string basis it is enteredasa single numeric value obtained by adding the reverse values of all strings that are reversed String 1 is 1 String 2 is 2 String 3 is 4 and String 4 is 8 For example if you want strings 1 and 4 to be reversed you would enter a reverse value of 9 1 8 Sorry it s cryptic but it s not something you need to tweak every day REVERSE n a Defines reversed status Y N for each string in cluster n value a is the sum of the reverse values for all reversed strings REVERSE 1 15 would indicate that every string in cluster 1 was reversed REVERSE 2 0 would mean that none of the strings in cluster 2 are reversed The zigzag command is typically used when you are building a matrix of pixels and the height of your matrix is less than the string size Say for examp
11. changes on the pixels type SAVE 0 When finished if you want to go back to your original setup just LOAD 1 then SAVE 0 and you are back where you started Remember the pixels will ALWAYS operate on whatever configuration was last saved into page 0 unless you have dynamic page selection enabled SAVE n where n is a memory page number from 0 to 7 Writes the currently displayed configuration to the specified memory page LOAD n where n is a memory page number 0 7 Loads the specified memory page and displays the information on the web page BOOT 999 will restart the E682 make sure you SAVE first if you have made any changes QUIT n Quit tells the web server to stop running in n seconds Not generally used on the E682 The UNIVERSE command is used to map physical DMX universe numbers to the E682 s 6 virtual ethernet paths or sockets This information is displayed in the E1 31 Packet Statistics section of the web page In a simple configuration the first E682 might be assigned to universes 1 6 the 2na to Universes 7 12 etc But these assignments can be made using any 6 universe numbers and universe numbers can be as high as 63 999 Important please make sure that there are no duplications in other words don t assign the same universe number to more than one socket It won t work Command Example UNIVERSE 1 1000 this command would assign DMX universe 1000 to socket 1
12. chip types are equivalent to other chip types for example the WS2811 is the same as the 1804 so use chip type 3 for WS2811s Also the CYT3005 is compatible with the TLS3001 so use type 8 for either of those CHIP n x where x is a valid chip number 0 8 Defines the type of chip used on cluster n s pixel strings Example CHIP 1 0 sets chip type to 6803 for cluster 1 The pixels command sets the number of pixels assigned to each string of this cluster A pixel here refers to a set of 3 DMX channels A pixel may light more than one light on the string if the group size is more than 1 If the grouping is 1 then of pixels string length If the grouping is more than 1 then Pixels X Group Size String Length For example if you have a 50 count string and will be lighting up LEDs in groups of 5 you would set pixels to 10 group to 5 and the string length will be automatically calculated as 50 PIXELS n aaa Defines the number of pixels on each string in cluster n Example PIXELS 1 50 The Group command tells the E682 how many consecutive lights on the string to light up for each set of 3 DMX channels Normally this will be 1 meaning you are controlling each LED individually This gives the maximum possible flexibility but at the expense of number of DMX channels used Using pixel grouping in situations where control of every pixel isn t needed

14. on the 3 DMX channels that are assigned to each pixel Ordinarily this will be RGB meaning red first followed by green then blue For whatever reason some pixel strings use other orders such as BGR instead In any case the RGB entry allows you to handle ANY possible combination that you may encounter and that eliminates the need to have non standard color orders in the sequencing software that s sending the SACN data to the E682 To the controlling software every pixel will appear to be R first followed by G then B The next entry is the DMX Address Range for this cluster Starting DMX addresses are entered as S CCC where S represents a socket number from 1 through 6 and CCC is the channel number from 1 through 510 It s important to understand that the DMX address assignment on the E682 is actually a 3 step process The first step involves configuring the lighting control software that will drive the E682 You will need to assign your pixels to specific channels in specific DMX universes The configuration of the various programs available to drive the E682 is beyond the scope of this discussion In the second step we assign each of our 6 available sockets think of a socket as a virtual pathway that joins one DMX universe from your PC to the E682 to a DMX universe number You obviously want the universe numbers that the E682 responds to to match th
15. power select jumpers as follows If the pixel power supply connected to J19 is 5 volts install a jumper between pins 2 and 3 ONLY For pixel power voltages greater than 5V on J19 install a jumper between pins 1 and 2 and a jumper between pins 3 and 4 Finally if you elect to power the E682 from a separate power supply install a jumper between pins 1 and 2 and a jumper between pins 4 and 5 In this case connect th external supply to J17 the upper terminal is positive and the 2na terminal from the top is negative Th xternal power supply should be from 7 to 24VDC and capable of supplying at least 300ma or 1500ma if powering an ethernet switch from J17 The external supp The ly should be current limited or fused at no more than 2 amps E682 contains circuitry to protect the controller s electronics if a voltage of greater than 5 volts is connected when the board is jumpered for 5 volt power This will result in the 2A fuse blowing If the 2A fuse is found to be open double check the power select jumpers The proper configuration of these jumpers is shown on the E682 silk screen at the extreme right edge of the board The other set of configuration jumpers is highlighted in the board layout at the upper left and is labeled J22 These jumpers one per output cluster are installed to enable the 2 wire balanced output feature explained later in this manual LED I

17. 19 described later Pixel Power Supply Connections The E682 must be used in conjunction with an appropriate pixel power supply The specifications of the pixel power supply will depend on the type and quantity of pixels being driven 5 volt and 12 volt pixels are the most common If using 2 different voltages of pixels simultaneously you will need either 2 separate power supplies or a single supply that can supply both voltages Power for the pixels is connected to the two large 2 terminal screw blocks on the bottom edge of the board designated J18 and J19 The left hand terminal is marked positive and the right hand terminal is negative There is a legend silk screened on the board below the terminal blocks Power to the left hand connector J18 supplies power to the pixel strings connected to connectors 1 1 through 2 4 Power to J19 powers the pixels on connectors 3 1 through 4 4 and usually supplies power to the E682 itself as well One power supply can power both sides either by running 2 sets of and wires from the power supply one to each terminal block preferred or by connecting power to one terminal block and installing a jumper wire between the 2 positive terminals Alternatively the E682 can be powered by 2 separate power supplies one driving each side of the board To know the current requirements of the pixel power supplies you need to know the power requirements of

X channels this cluster needs The number of DMX channels needed by a cluster is of strings of pixels 3 A single cluster may have all of it s addresses within the same socket universe or may span across multiple sockets universes Reverse is four Y N Yes No values one for each string in this cluster A Y means that the string is reversed ie it is driven from the far end Sometimes it s advantageous to be able to do this For example if you are lighting a roofline and want to use two 128 pixel strings That would give you a total length of gt 60 feet The easiest configuration is to mount the controller at the midpoint of the 2 strings that keeps each string connection short But to do that and for it to work properly as a single long string the controller needs to know that one of those strings is reversed That way as you light up pixels 1 256 in order they will light up from one end of your roofline to the other not from the middle to one side then from the middle to the other Or if you want to connect your mega tree strings at the top but your sequencing assumes pixel 1l is at the bottom just define all strings as reversed and you are good to go Zigs Well this one can be a bit confusing Let s say you re doing a mega tree and you want it to be 50 pixels high but your strings are 100 pixels long If you light pixels 1 100 in order you want to light the first strand f
