Power Supply to the Camera
In order to supply an operating voltage to connected cameras, a
direct current can be drawn from the pin header row. This is
directly connected to socket X300 or, depending on Jumper JP301,
drawn from the PC/104 connector or the integrated supply voltage.
This function was not available with the eGrabber-2.
•
Changing the Old Driver Version (for V3.0)
If software has been developed for the eGrabber-4 that is still used
in conjunction with older driver versions (before Version 3.0),
please read the following notes:
-
The Window’s DLL was expanded with the function
GetVersionNumber. If a non-valid function pointer is returned
with
GetProcAddress, then a newer version of
GR4CDLL.DLL is required.
-
Set_Image Function:
In previous versions, the hpos and vpos parameters in the
Window’s DLL were required to be set to 1 in order to place the
cropped image in the upper left-hand corner of the digitized
image. Now the parameters accept only even values, this means
that hpos and vpos must be set to 0.
