Overview
INLINE-TTL-S Inline TTL Shutter is a small mechanical laser-cut shutter that is positioned between two
UV/VIS-optical components. The shutter is controlled by a small circuit board that is powered by a 12
VDC signal. The circuitry in the INLINE-TTL-S monitors Pin 13 of the 15-pin D-Sub connector for a 5-
volt TTL signal and triggers the shutter when the 5-volt signal is received.
The maximum frequency at which the INLINE-TTL-S can operate is 5Hz (5 shutter cycles per second).
