Chapter II Model 801and 802 Manual
All the hardware setups are through the software—LedStudio.
- Entersetup dialog box
Click the “software setup”, as shown in below figure;
And then will appear a dialog box, as shown in below figure;
As soon as the above dialogue box appears, input “linsn”, then password “168”. (Computer screen shows nothing when inputting “linsn” by keypad.), then enter setup dialog box, as shown in below figure
II. Sender setup
Display mode: if PC works under the 1024*768 resolution, nothing changes; otherwise choose the right resolution of PC, then click “Save on sender”. (Remarks:1024*768 resolution is recommended)
Default: when the LED display brightness dim suddenly without any reason, click Default and Save on sender will solve the dim problem.
III. Receiver setup
Before doing the configurations, get some knowledge of each item would do much help.
Drive chip: Optional for PWM chip, general chip and etc.
Present scan mode: after finishing intelligent setup, software will recognize the scan mode of the module.
File: after finishing intelligent setup properly, users will get a *.rcg file. Users can name it. For example: full-color 1/8 scan 8 rows/zone.
Led display refresh frequency: The higher the refresh frequency is, the more stable image will be on the screen. If a camera is used to shoot image on the LED display, to avoid ripple and flicker, user should set the refresh frequency above 600HZ. Generally speaking, for double-color screen, refresh frequency set as 60—75HZ; For indoor full-color display, 180—600HZ; For outdoor full-color display, 300-1200HZ.
Synchronous frequency: For bi-color display, it doesn’t matter; for tri-color display, this item has to be ticked.
Gray level: In general, gray level 256 is Ok for double-color display; 4096 for indoor display; 16384 for outdoor display. The higher the gray level is, the better the image will be.
Scan clock: the max scan clock is up to the design and performance of drive board. If drive board has a reasonable design and good performance, it can reach high scan clock, so single receiving card can support more pixels.
Duty ratio: it is the duty ratio of scan clock, changing this will affect the scan clock. Generally, the duty ratio is 50%.
Blanking time: It is used to fix brightness leak. Set 3000 for double-color display; 200 for full color display. (Real pixel and virtual pixel).
Gray equalize: The default value is 1; generally, most Led screens don’t need to adjust this item. The normal gray displays from darkness to brightness, as shown in below figure:
Some panels are not of good quality, so the gray level doesn’t display regularly; if users adjust this item, it is possible to make the gray level normal. The adjust value range: 0-15.
Virtual display: if the led display is virtual display, and it works under virtual mode, user should tick this item.
Max width: Pixels that one receiving card can max support. It is related with refresh frequency, gray level and scan clock, and it will change accordingly to the three items. Normally, raise up the refresh rate and the gray level will low down the max width; but reverse to the scan clock.
Actual width: actual width of one receiving card need to support.
Max height: Pixels one receiving card can support for the height. It is relevant to the design of led display drive board.
Actual height: actual height of one receiving card need to support.
Intelligent setup: There are 7 steps. (Some steps will be skipped according to different display panel.) By doing the intelligent setup, Linsn controllers will fetch the info of the led display, such as scan mode, chip decode, module size, signal trend etc, then apply the suitable connecting program from the firmware. Before doing the intelligent setup, user must collect the info of the following picture: the info can also get from the led display manufacturer.
Load from files: If user get a .RCG file from the manufacturer or user have generate a .RCG file by doing intelligent setup before, for the same kind led display, user can upload the .RCG file and make the display work fine.
Save on files: If user has made a successful intelligent setup, there should be a .RCG file generated. By saving on files, user can save the .RCG file.
Send to receiver: After finishing the intelligent setup, or change any parameters, or upload any .RCG or .CON files, user has to click “send to receiver” to take effect on the led display.
Save on receiver: Click this item can save data in receiving card permanently. If not, the data lost when power is down.
Intelligent setups are shown below: (Make sure the correct connection for the flat connected panel with hub card, otherwise the “Intelligent setup” can’t recognize your panel properly. Entering the setup interface, users must do the operation and watch testing panel carefully at the same time, because all the operation setups must follow the panel’s instructions. )
- Click the “intelligent setup”
- Choose the type of display (Single-color, double-color, full-color real pixel, full-color virtual pixel.)
If display is virtual pixel, you should choose the right virtual pixel sequence; there are four choices in total, as shown in below figure.
(Notice: one virtual pixel consists of two red lights, one green light and one blue light. The up row one is red A, and the down row one is red B.)
- Input the pixels of a module (also called panel, shown in below figure), width (X), height (Y);
- Input the quantity of the data input port, and the quantity of data group for every data input port, taking the full-color as an example, data input port– how many data input ports at back of each full color module; Data group– how many R, G, B data groups for a full color module. as shown in below figure
- Data type, (red, green, blue) red, green and blue unite as one, three colors serial; red, green and blue unite as one, four colors serial. Generally speaking, the first data type (Red, green, (blue) separately) for Led display, the other items for light-decoration.
- Choose the row decode mode (Unknown or not in the following options\static, no decode\no decode chip, row drive directly, with OE\no decode chip, row drive directly, no OE\chip 138 decode\chip 139 decode\chip 145 decode\chip154 decode\chip 164 decode\chip 192 decode\chip 193 decode\chip 595 decode\chip 4094 decode)
- Module cascade direction: how signal goes. look from the front of LED display: data from right to left; from left to right; from top to down; from down to top. Choose the right one according to your cascading modules.
- Watch module change: choose the right status, for example, status 1 shows white, and status 2 shows black.
- Watch the module, and choose the right status.
- Compared status 1 with status2 of the module, watch which one is brighter, for example: status 1 is brighter than status 2. Choose the right one.
- Watch the color that the module shows, for example, status 1 displays red, and status 2 displays green. Select the right one.
- Watch the module: one row is bright or multiple rows are bright; when multiple rows are bright, check how many interval rows. As shown in below figure.If there is no black (mid) row between the bright rows, select 1 row for the interval row, as shown in below figure: 4 rows for bright rows, and 1 for interval row.13. Watch which pixel is bright in the module, then click the corresponding grid on the computer screen, after clicking the grid, you will find another pixel will be bright on the module, then you continue to click the corresponding grid on the computer screen, after click it, another pixel will be bright on the module…. By analogy, follow the instruction on the module; the computer will inform you when all the pixels are choice-finish.15. Setup the refresh frequency and gray level according to requirement of your Led display. Pixel by pixel/ module by module correction: It includes four modes: single pixel; 2*2 module; 4*4 module; 8* module. (1). Setup actual width pixel and actual height pixel for your display (cabinet), and then click “Send to receiver”.(3). Click “Edit correction data”, shown in below figure.
- (2).Choose the correction mode: Single pixel, 2*2 module, 4×4 module, 8×8 module. (Remarks: single pixel correction can support the max pixel 96*64=6144, if surpass, please choose other correction modes.)
- Pixel by pixel correction data setup steps
- The single pixel mode can support the max 6144 pixels. If surpass 6144 pixels, please choose other modes.
- 14. After finishing “intelligent setup”, send it to the receiver; if saving it (.RCG) into file in computer, you can load it from the file directly when you use this kind of module next time.
- Choose the right one according to your module.
- Notice: Interval rows mean how many black (dim) rows between two bright rows, and then add one bright row for the total interval rows. (You must figure out all the bright rows in the panel, but for the interval rows, you only need to figure out how many rows between two bright rows.) For example, as shown in below figure, there is one black (mid) row between two bright rows, choose 2 (1+1=2) rows for the interval rows, 4 rows for bright row.
- Correction by hand: Select the color that needs to be corrected (red, green, blue), and choose the pixels that require to be corrected, using ctrl key can select multiple pixels; then click “Add brightness” or ”lower brightness”, adjust the ideal brightness, as shown in below figure,
- and then click “Submit”, then click “Send to receiver”; click” Save to receiver” can save it permanently. Making a backup in the computer file in order not lose the data.
- Create from picture: C: Make screen display red, green, and blue separately; take 3 to 5 pictures for each color. (Request: fix the camera on a tripod rest; taking the pictures which can see every single pixel clearly)
- D: Transmitting the pictures to computer, click “Create from picture”, as shown in below figure
- A: Use high-class professional camera. Pixel resolution should be over 10 million pixels; advising to use CANON, EOS400D and CANON EOS5D, and EOS400D has been tested already, the effect is good.
