SCANLAB's RTC® PC interface boards provide synchronous, interference-resistant control of scan systems and lasers in real time.
A high-performance signal processor and the supplied DLL simplify programming under Windows. Alternatively, industry-proven software packages from various third-party vendors are also available for handling a palette of standard applications.
Software instructions are loaded alternately in the RTC®'s two list buffers, processed by the DSP, and output as 16-bit control signals every 10 µs to the scan system. The RTC®'s processor automatically performs vital steps such as micro-vectorization and image field correction. Laser control is synchronized with the scanner movements. Various programmable laser signals are available for vector and bitmap processing.
The RTC®4 is downward-compatible with the RTC®3. Additionally, the RTC®4 is capable of communicating with the processors onboard SCANLAB's new 
intelliSCAN®
scan heads – thus, it furnishes to the control PC the real-time
stream of scan head axis status parameters and enables extensive scan
system diagnosis possibilities. Optimized intelliSCAN® scan head tuning profiles for diverse processing tasks can be selected via software commands.
Compared to the RTC®3, the RTC®4 offers more memory, faster performance and additional software instructions (e.g. arc command). For controlling external components, the RTC®4 provides 16 digital input ports and 16 digital output ports.
SCANLAB's RTC® PC interface boards are available with numerous options, providing the extensive flexibility system integrators need for meeting diverse customer requirements. Furthermore, an I/O extension board is available for controlling additional external components.
