3 Lens Substitution Optics and Lighting Lens Substitution The following procedure will change the appropriate settings in the Vision HAWK to allow the camera to focus properly after the lens has been changed. Please note that the Vision HAWK camera will use default lookup tables for the focus when the lens selection is changed, so the actual focus distances may not be as accurate as the lens that was shipped with the unit that was factory calibrated. Since default lookup tables are used, the Vision HAWK may not focus over the full focus range that is normally seen when using the factory calibrated lens.
After the lens has been changed via the parameters below, the new values will take effect the next time that the lens focus is modified. 1. Boot the Vision HAWK Smart Camera. 2. Connect to the Vision HAWK via Telnet using the IP address of the camera. 3. Send the following command after the Vision HAWK has booted: stopAll The response should be "value = 1 = 0x1" . 4. Send the following command: GetCurrentLens() One of these 4 responses will appear: 1 = 15° 2 = 30° 3 = 45° 4 = 12° 5. After the camera has booted, send the following command (choose the appropriate number based on the new lens): SetCurrentLens(1) (to change to 15° lens) The response should be:
"Now Set to 1 = 15deg" "value = 0 = 0x0" SetCurrentLens(2) (to change to 30° lens) The response should be: "Now Set to 2 = 30deg" "value = 0 = 0x0" SetCurrentLens(3) (to change to 45° lens) The response should be: "Now Set to 3 = 45deg" "value = 0 = 0x0" Vision HAWK Smart Camera Guide 3-3
