Dimensional Drawing 6. Installation Instructions (1)Remove the focusing knob from the telescope. (2)Select the appropriate mounting bracket for your focuser model. (3)Install the connection bar (mounting plate). (4)Attach the electronic focuser body to the bracket. (5)Engage the focuser gear with the bracket gear. (6)Tighten the handle screw. Complete connection diagram (including 12V Type-C) 7. How to Configure Parameters Wired Mode (using N.I.N.A. as an example): The configuration interface features a black background with white text. The default maximum travel of the focuser is 100,000 steps, and the position after power-on is the midpoint (i.e., position 50,000). In N.I.N.A., first click "Refresh", then select the device from the dropdown list in the equipment panel, then click "Configure" to open the configuration interface. Here you can modify the maximum travel of the electronic focuser. The adjustable range is between 100 and 1,000,000 steps. Click "Update" to apply the change. After modification, the maximum travel and current position will refresh immediately, and the new maximum travel value will be retained for future use. The detailed steps are as follows: (1)Connect the Type-C data cable, then open N.I.N.A. (2) Click "Scan for Devices", then locate and select "Askar-WAF" under the ASCOM Alpaca module in the taskbar. (3)Click "Settings" and wait for the web interface to open. (Two image placeholders) (4)According to the travel of your imaging equipment's focuser, set the maximum travel. (Reference: Step 19800 = one revolution of the WAF output shaft = one revolution of the focuser coarse adjustment knob) (5)After entering the new Max Step value, click "Update". A green message reading "Maximum travel has been updated to" will appear upon success, then close the web page. Example illustration (showing 10 revolutions, i.e., Step 198,000): Wireless Mode (using the Askar App as an example): When using the device for the first time, you need to configure the network via the mobile app using Bluetooth. Connect the device to the same local network as your computer/mobile device, so that you can control it from the app or from your computer. After network configuration is complete, you can either control it via the app, or via N.I.N.A. (ensuring that your computer and the device are on the same network). Each time you subsequently use the electronic focuser, it will automatically connect to the network that was configured last time. If connection fails, it will enter Bluetooth configuration mode after 7–8 seconds, and you can reconfigure the network using the app. Detailed steps are as follows: Network Configuration Procedure 1. Open the "Device" tab at the bottom, then tap "Device Network Configuration". 2. Grant system permissions (Bluetooth, etc.). If previously denied or permanently marked as denied, go to your system settings, enable the corresponding permissions for the Askar App, and try again. 3. You will enter the "Scanning for Devices" page: (1)The app will scan for approximately ten seconds (you can also refresh manually). (2)The list will distinguish between "Askar" devices and ordinary Bluetooth devices for easy identification. (3)If the list is empty, a prompt will usually appear: "No devices found, please confirm that the device is in network configuration mode." (4)If Bluetooth is turned off, you can enable it according to the on-screen prompt or go to the system Bluetooth settings. 4. Select your device from the list and wait for connection. After successful connection, you will enter the "Wi-Fi Selection and Configuration" page: (1)The page will indicate: "Connected to this BLE device, please select the Wi-Fi network that the device will join. The device only supports 2.4 GHz. Failure may occur if the network cannot switch frequency bands or due to other reasons." (2)You can first "Scan for Wi-Fi". If no results appear, confirm that location and Wi-Fi are enabled, then retry. (3)The list may include "Saved" networks (hotspots for which a password was saved during this session) and "Avai…
