Page 4: Introduction
With the IRC-320 line VDS Vosskühler offers infrared cameras based on a microbolometer sensor with 320 x 240 pixels for the LWIR range. As all previous VDS CCD cameras also the IRC-320 provides an excellent image quality. The series IRC-320 is designed as OEM modules with Gigabit Ethernet output for the long-lasting installation. -

Ethernet models of this camera internally use Camera Link signals, so many of the facts mentioned in the chapter 6.1 are also valid for the Gigabit Ethernet interface option.

Page 19: File System
Ex factory the camera is usually already equipped with several files, containing system and correction data. The IRC-320 don’t use the whole 64MByte, so that a customer can also use this memory for own data. Refer to chapter 10.10 “Upload a File to Flash ( Q )” for details. VDS Vosskühler GmbH IRC-320... -

Avoid triggering the camera while the calibration is in progress. Depending on the camera model and current j parameter configuration, the actions accomplished by the k command and its output at the serial interface may vary.
