In order to read from any given

Depending on the frame grabber manufacturer the function “uart_send” may have
different syntax – refer to frame grabber manual for the correct function call. To
prevent the serial buffer from being overwritten after each command, a delay of at
least 1050 microsecond must be introduced.

EPROM Configuration
To access the EEPROM the same sequence of characters have to be transmitted to the
camera via the Camera Link serial interface. The format of the serial interface is the same:
ASYNC with 8 data bits, 1 stop bit, and no parity. The default baud rate is 9600 bps. A delay of
10 milliseconds is required after each command. Only the user space is available for read and
write. The factory space is read only.
