Do not use it togetherwith other common lines.Output CircuitUse the output controller parallel output (NPN specification) circuit within the rangesillustrated below.

Thisvalue changes depending on what type ofstrobe is attached.B: Strobe response time. Determined by thestrobe.C: Strobe flash time. Determined by the strobe.In the case on the NPN outputcontroller, use a flash for whichthe time from when the flashoutput synchronization signalgoes on to when the light gen-eration finishes is 550μs orless. For the Photo−MOS con-troller, use a flash for which thistime is 450μs or less.A strobe can only be used forthe flash output for theANM830A camera in framemode.OFF
