4.5. Signal Delay
With the system, you can set the signal delay time or pulse width for the various signals that are
input and output. Pulse width and delay settings for the various signals to input/output are made with
PFV or the Remote Controller (optional). The content of each setting is listed in the chart below.
Setting Item Setting Range (Value)
TRIG TTL IN DELAY 0-60 (s) 100 ns units
SYNC IN DELAY 0-1/frame rate (s) 100 ns units
GENERAL IN DELAY 0-60 (s) 100 ns units
TRIG OUT WIDTH 0-1 (ms) 100 ns units
SYNC OUT DELAY 0-1/frame rate (s) 100 ns units
SYNC OUT WIDTH 0-500 (us), 1/frame rate (s) at 2,000 fps or higher 100 ns units
EXPOSE OUT DELAY 0-1/frame rate (s) 100 ns units
SYNC OUT TIMES 0.5, 1, 2, 4, 6, 8, 10, 20, 30 (* x1 is standard output)
SYNC OUT TIMES
The SYNC OUT TIMES number shows the times to magnify the SYNC signal (vertical sync signal) that is output
from SYNC OUT.
Example: Frame rate is 1,000fps, SYNC OUT TIMES setting is 2.
Example: Frame rate is 1,000fps, SYNC OUT TIMES setting is 4.

An accurate frequency is output, but when SYNC OUT TIMES is set to a large value with a high
frame rate, the setting may result in frequency errors.
