Input / Output:

Input:
Enables external triggering of the stroboscope. Connection via a 3-pin, 3.5 mm jack plug. The input is TTL-compatible (24 volts max.).
Minimum trigger pulse width: 500 ns.
Delay: typ. 13µs between trigger pulse and flash ( dbx ) or typ. 16µs ( dax ); trigger edge selectable (rising or falling edge).
The internal oscillator and the rotary knob for frequency setting are deactivated as long as a jack plug is plugged in.
Output:
Enables synchronization with other devices. Connection via 2-pin, 3.5 mm jack plug. The output is TTL-compatible and corresponds to the flash frequency of the stroboscope. Trigger edge selectable (rising or falling edge). Pulse duration: 40 µsec.
