Camera interfaces
Synchronization output (pin 6)
Use this signal for the following:
•
Synchronize external devices to the effective exposure of Bonito. Examples
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
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 inter-
face and the available port(s) via Camera Link concurrently may lead to unex-
pected results. Both interfaces share the same receive buffer, so the characters
of simultaneously sent commands may be randomly mixed up. For more informa-
tion on general command syntax: see chapter
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.
