Synchronization output (pin 6)
Use this signal for the following:
• Synchronize external devices to the effective exposure of Bonito. Exam-
ples of external devices are flash lights, flash strobes or timer circuits.
• Reduce the timing jitter of start and end point of exposure. Several modes
are available: for more information see chapter
Synchronization output
(J) on page 44
The output is a RS232 compatible driver, signaling at +/- 6 V levels typically.
The output delivers a reliable, low-jitter transmission, even over relatively long
cable runs. The driver adds a delay of 0.75 μs typically at rising or falling edge.
Serial interface (pin 7-8)
The camera can be controlled externally via an RS232 COM Porty by using serial
interface at pin 7 and 8. A simple terminal program (e.g. HyperTerminal) is suf-
ficient for manually controlling the camera. Note that operating this serial
interface and the available port(s) via Camera Link concurrently may lead to
unexpected results. Both interfaces share the same receive buffer, so the char-
acters of simultaneously sent commands may be randomly mixed up. For more
information on general command syntax: see chapter
Serial I/O on page 22.
Note

Only cameras with firmware CMC.040.01.07 or newer support
this feature.
If you use a camera with an older firmware version: don‘t con-
nect pin 6.
Caution

Do not directly connect this output to a TTL or CMOS logic input.
Input may be destroyed, because output delivers several 10 mA
at voltage levels - 6 V to +6 V. These voltages may exceed the
absolute limits of the input.
