The C-RED 3 firmware communicates with the user through the serial line embedded in
the Camera Link
®
cables.
Usually, the driver for the frame grabber exposes the serial line of the Camera Link as a virtual COM
port on the acquisition system.
To communicate both ways with the camera, the COM port must be configured with the following
settings:
115200 Bauds, 8 bits, no parity, 1 stop bit, no flow control
.
USB (for C-RED 3 USB only)
C-RED 3 USB uses a USB 3.1 Gen 1 interface.
It is detected as a composite USB device (control int acquisition interface).
The control interface is exposed as a standard serial port whereas the data acquisition interface is
exposed as an Imaging device.
So, as for Camera Link
®
, both image and configuration interfaces are available.
The configuration interface is also a pseudo COM port (USB virtual COM port).
Before using USB interface, the C-RED 3 USB driver must be installed on the acquisition computer.
(cf. doc install C-RED 3 demo software).
When the camera is detected on the USB 3.1 Gen 1 port, Windows ® automatically installs the C-RED
3 drivers.
Under Linux, the Firstlight USB SDK manages the frame acquisition frame using the standard libusb
directly.
The USB virtual COM port is also managed directly by the standard Linux driver and is exposed as
/dev/ttyACMx.
