Bonito Technical Manual V2.2.1

Synchronization output (pin 6)

Use this signal for the following:

• Synchronize external devices to the effective exposure of Bonito.

Examples of external devices: flash lights 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 39

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)

By use of the serial interface at pin 7 and 8 the camera can be controlled exter-

nally via an RS232 COM Port. A simple terminal program (e.g. HyperTerminal) is

sufficient for manually controlling the camera. Please 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 and thus

the characters of simultaneously sent commands may be randomly mixed up.

For more information on general command syntax: see Chapter Serial I/O on

page 20.

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

connect 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 ... +6 V. These voltages may exceed the

absolute limits of the input.
