2.6.4 Applying New Parameters

New capture parameters (such as exposure time or gain settings) can be transferred to the camera

via software at any time. Depending on the operating mode, these settings will not always be

immediately effective for next image, however.

Freerun mode

In freerun mode, the camera is internally busy with capturing the next image while new

parameters are transmitted to the camera. Depending on the exact time of transmission, new

parameters might only come into effect two or even three images later.

Trigger mode

In this mode, the camera reverts to idle state between two images. When you change the camera

parameters, the new settings will be applied immediately to the next image.

2.7 Firmware and Camera Start

Every DCx camera has its own firmware that handles internal processes in the camera. The

camera firmware varies from model to model.

USB DCx Cameras have a two-tier firmware that is uploaded to the camera each to you connect it

to a PC:

1. Common firmware (uc480 boot)

The general firmware identifies what camera model you have connected, and uploads the

corresponding firmware.

2. Model-specific firmware (e.g.: uc480 DC1240x series)

The model-specific firmware is named after the camera type and provides the functions of the

relevant model.

Note

When you connect a USB DCxCamera with a Windows PC or a new USB port for the first time, it

is detected as a new device. This is normal standard behavior of the operating system.

The USB DCx Cameras firmware is part of the driver. The automatic upload always loads the

firmware that matches the driver installed in the camera.

2.8 Digital Inputs / Outputs

All DCx cameras (see Model comparison), except DCC1545M and DCC1645C, come with opto-

isolated inputs/outputs that can be used for triggering the camera and for flash control. DC3240x

cameras have in addition general purpose I/Os (GPIO). Use of the GPIOs for flash control is

possible to a certain degree. External triggering via the GPIO is not supported.
