GPS compares the battery, most GPS uses four alkaline batteries and can be turned on for 20-30 hours. The time on the manual is not very accurate. Please pay attention to carry the spare battery when using for a long time. Most GPS have a permanent backup battery that ensures that all data in the memory is not lost when there is no battery. Since the GPS has no direction indication function when it is stationary, it is useful to bring a small north arrow at the same time. When marking a waypoint, GPS provides a default waypoint name, such as LMK001, which is difficult to remember. Although it can be changed to a better name, but the input is inconvenient, it is very difficult to use the up and down arrows to select letters. It is a good idea to start with a short English name, such as 6 or 9 letters, which is still not easy to remember, and then take a small tape recorder/interview machine to record at any time.

1. Use maps
GPS has the best effect when used in conjunction with detailed maps, but domestic large-scale maps are very rare, and GPS usage is limited. If you have an accurate map near your destination, you can plan the route in advance, plan on the map, make a trip plan, and create one or more lines (ROUTE) according to the complexity and mileage of the line. For the coordinates of the route feature points, enter the GPS "legs" to establish the line, and enter some individual marker points as the waypoint (Landmark/Waypoint) into the GPS. GPS manual input of data is a rather cumbersome thing. Please think about entering more than 20 alphanumeric characters such as name and coordinates for each waypoint. Each alphanumeric character can be pressed up to a dozen or so times to appear. Haha This is why someone is willing to spend a lot of money on wiring and software to upload/download data using a computer. Bring a map! The first one is to use GPS to determine the position of the map on the map. The second is to follow the direction indicated by the guiding function and find the way to the target. At the same time, it is necessary to record the actual coordinates of each planning point. It is better to establish another actual line for each planned line, which can be used as the original road return, and can be saved as the actual route data for later generations.
2. No picture use This is a more common way to use it.
1.) Use waypoint fixed point: It is often used to determine the rock wall coordinates, determine the hole coordinates or other coordinates like the starting point, turning point and camping point of the line when exploring the hole. Simple to use, MARK a coordinate will do. Find the point: the coordinates of the location you are looking for must already exist in the memory of the GPS in the form of a landmark/waypoint. It can be the point of your previous MARK or the data obtained from a friend you have been to before, manual/computer Uploaded waypoint data. Press the GOTO button, select your destination waypoint from the list, and then go to the “Guide†page, which will display the distance, speed, target direction angle and other data from the target, according to the direction angle.
2.) Use the route to enter the route: If you can find the route information recorded by the friends you have been to before, enter them into the GPS to form the route, or (commonly on the original route to return) the previously recorded waypoints into one line. Route Orientation: Activate a route. In the same way as “find the pointâ€, the “Guide†page will guide you to the first point of the route. Once it arrives, the target point will be automatically replaced with the next waypoint. The page guides you to the second point of the route... If you deviate from the route and cross some intermediate points, once you return to the route, the "guided goal" will skip the points you have bypassed. Is the next point on the line that corresponds to your current location.
3.) The backtracking backtracking function is actually a special method of inputting a route, which is very good when returning from the original path. But there are some considerations,
Because the domestic large scale is not suitable, so every time friends go out to play, they can bring a set of correct data back. When there is a map, sort out a set of maps + measured route coordinates. When there is no map, sort out a line description + measured coordinates, send it to Online, gradually accumulate, form our own geographical database, and later friends with this route can be exempted from the employment guide and lost!
Led Strip Controller is to control the LED light bar of the instrument.
Features of Low-voltage LED Strip Controller is to control more than large ones, to control the use of the serial signal transmission purposes, the general control unit 512 need only four control connection, serial LED controller LED light sources require board register with the controller can choose models NE040S controller.
LED strip controller can be divided into two categories: led light bar products, high power controller and led light bar products, serial controller.
LED strip are generally designed voltage 12V-36V, the number of each loop LED 3-6 series, with resistance step-down current limiting, each loop current 20mA or less. LED products from a number of loops of the LED composition, the advantage of LED Strip Controller of low voltage, simple structure, easy to design;
Drawback is: LED Strip Controller is large-scale products when the current great need to configure low-voltage switching power supply. As the shortcomings of the product limitations, low voltage transmission can not be long-distance, Caused led strip controller is limited to small size products, such as signs of text, small designs. According to this feature, the controller design specifications: 12V selection of 75A / 30V MOS power control, the output current 8A / Road.
Mingxue Optoelectronics Co.,Ltd. has apply the I S O 9 0 0 1: 2 0 0 8 international quality management system certificate, As for LED Strip Controller , we apply the CE, RoHS and SAA certificate for our led lighting product.
