CPU idle states
Windows only: Processor operating states (idle states/C-states)
Modern processors have various operating states, so-called C-states, that are characterized by different power requirements. When the operating system selects an operating state with low power consumption (unequal C0), the USB transmission efficiency may be affected (see also is_Configuration()).
Camera parameters for opening a camera
Here, you can set whether to apply the parameters stored on the camera automatically when opening the camera. You must first store the camera parameters on the camera using the is_ParameterSet() function or via the corresponding function in the uEye Cockpit.
This setting applies to all connected cameras. If no parameters are stored on the camera, the standard parameters of this camera model are applied (see also is_Configuration()).
In this mode all specified GigE uEye cameras are opened internally by the driver at the system start and all necessary structures are set up. For the user the camera is available and can be opened as before. The opening and closing is carried out much faster as the structures must not be set up or established (see also is_BootBoost()). If a camera is added to the boot boost mode, this specific camera is shown as unavailable to all other PCs in the network.
You can enter either single camera IDs or a range, e.g. "2-9;14". If you enter several camera IDs, they have to be separated by a semicolon. Which camera IDs are set currently can be seen in the "Current boot boost IDs" field. In the IDS Camera Manager the cameras are marked with "Yes (BB)" in the "Free" column which are running in the boot boost mode.

•To activate the boot boost mode, select "Enable" in the IDS Camera Manger ("Additional functions" window). To select a specific camera, set the camera ID into the input field and click on "Add ID".
•To remove a single camera, set the camera ID in the input field and click on "Remove ID".
•To remove the complete list, click on "Clear ID list".
•To replace the current camera list with a new list, set the new camera IDs into the input field and click on "Set ID list". This will replace the current with the new camera IDs.
COM Ports
The "Additional functions" dialog box allows installing virtual COM ports for communication through the serial interface of the GigE uEye HE camera. The following sections show you how to set up and use the serial interface.

Setting up the serial interface on the GigE uEye HE
Before using the serial interface on the camera, one or more virtual COM ports have to be installed on the PC. Most systems support up to 255 COM ports; COM1 to COM8 are often assigned operating system functions by default. You can check the current port assignment in the Device Manager on your computer. Some older systems may not have more than eight ports; in that case you will need to assign the GigE uEye HE camera to one of these ports.
•COM port
In the drop down box, select the number of the port you want to install (default: 100). COM ports in use are marked "(used)" in the list.
•
Click this button to install the selected virtual COM port.
During the first installation of a virtual COM port, an additional broadcast port with number 255 is installed. Data sent to this port will be forwarded to all paired cameras.
You can install any number of virtual COM ports on a single system.
•
With this button, you can release a COM port that is marked "used." If the port number has been saved in that camera, it will be deleted in the camera, too. To release a COM port, select it in the drop down box and then click this button.
•
Click this button to assign the selected port number to the camera. The port number is saved in the camera's non-volatile memory and retained even when the camera is switched off. You can look up the assigned port number in the Camera Manager's expert mode. A COM port number can also be saved in a camera without a virtual COM port installed on the PC.

Testing the serial interface on the GigE uEye HE
|
|
•
Clicking this button opens a dialog box for transferring data through the COM port. The dialog box is provided as the uEyeComportDemo.exe sample program together with the C++ source code and is included in the uEye SDK.
This program allows sending ASCII characters to the COM port assigned to a camera. The characters are output unchanged on the camera's serial port. To check the proper functionality, you can connect a PC to the camera's serial port and read the transmitted characters on the PC's COM port.
Fig. 98: Data transfer through a virtual COM port
•Baud
In this drop down box, you can change the data transfer rate of the serial interface.
•Append
This drop down box allows appending the special characters "CR" (Carriage Return) and "LF" (Line Feed) to the ASCII text you want to transmit. Some devices with serial interface require ASCII strings to be terminated with CR/LF.
•Send file
Using these functions, you can send a file in either direction (output on the camera's virtual COM port or output on the PC's COM port).
