COM ports and UARTS

For each connected camera, Matrox Solios eV-CL offers a RS-232/LVDS-compatible serial interface to communicate with the camera. Each interface is controlled by the UART on the acquisition path of the camera (through the Camera Link connection). Each interface is mapped as a COM port so that it can be accessed through the Microsoft Windows API.

Board type

Number of COM ports




Use the Microsoft Windows library to access and control the serial ports. To view them in a Microsoft Windows operating system, refer to Microsoft Window's device manager, under Ports (COM & LPT). Alternatively, you can control and access the serial ports using MsysControl() with M_UART....

With Matrox Solios eV-CL, the Camera Link manufacturer's camera configuration application can access and control the serial ports.

Note that, if you have enabled the CLProtocol module for one of your cameras, the COM port associated with the acquisition path will not be available.
