To trigger both cameras off one trigger input in Sherlock 7, you can use one of the GIO configura-
tion files included on the VA61.
NOTE Sherlock does not give an error indication if you enable the strobes, and then
later write to one of the strobe output channels from Sherlock.
NOTE If the Genie camera outputs are defined as “Open” or “Close” (default) they
appear in Sherlock’s I/O, and change the output channel numbers.
