µs, which is max. 2.1 s after a trigger edge was detected.
Exposure time (shutter) and offset
The exposure (shutter) time for continuous mode and Trigger_Mode_0 is
based on the following formula:
Shutter register value x time base + offset
The register value is the value set in the corresponding IIDC 1.31 register
(SHUTTER [81Ch]). This number is in the range between 1 and 4095.
The shutter register value is multiplied by the time base register value (see
Table 121: Time base ID on page 261). The default value here is set to 20 µs.
A camera-specific offset is also added to this value. It is different for the
camera models:

• Switching trigger delay to ON also switches external
Trigger_Mode_0 to ON.
• This feature works with external Trigger_Mode_0 only.
