Product Info
RTC®3, RTC®4
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.
RTC®5
The RTC®5 control board provides synchronous, interference-resistant control of scan systems, lasers and peripheral equipment in real time. It is available as a PC interface board, as a PCI-Express board, as a PCIe/104 module or as a PC/104-Plus module.
A high-performance signal processor and the supplied DLL simplify programming under Windows. Software commands are loaded into the RTC®5's freely-configurable list buffer and processed by the DSP. Every 10 µs, appropriate signals are output to or read-out from the scan system, laser and peripheral equipment.
The RTC®5 communicates with scan systems via the new SL2-100 data transfer protocol. This protocol supports 20-bit control signals and thereby a 16x higher positioning resolution compared to the RTC®predecessor board. The RTC®5's processor automatically performs micro-vectorization and image field correction.
For laser control, various programmable laser signals are available for vector and bitmap processing. During execution, the board can provide automatic position/speed/vector-dependent readjustment of laser power.Furthermore, the scan system can be synchronized to the laser. This “output synchronization” is a prerequisite for exact and reproducible laser processing (see drawing) when the laser-pulse signal is defined by a fixed (external) laser clock, as is the case for ultrashort pulse lasers.
For SCANLAB scan systems with fully digital servo electronics (intelliSCAN®, intellicube®, intelliDRILL®, intelliWELD®, powerSCAN i), the RTC®5 also supports all possibilities arising from the iDRIVE®technology. This includes real-time monitoring and remote diagnosis of key operational parameters, simulation-assisted process optimization and the use of different dynamics tunings. The real-time feedback of scan-system speed can be used for speed-dependent laser control.
Numerous options provide the extensive flexibility system integrators need for meeting diverse customer requirements.
If you combine the RTC®5 board (PCI, PCI-Express) with SCANLAB's laserDESK®software, you can easily create and execute professional laser jobs.
RTC® SCANalone
SCANLAB's RTC® SCANalone Board enables real-time control of scan systems and lasers without requiring a PC. The board's high-performance signal processor and extensive internal memory make this possible. The only item required for operation is an external power supply.
Marking data can be loaded via a removable MMC memory card or by using the built-in USB 1.1 interface. The board's internal memory can accommodate up to one million list commands – a capacity that meets the needs of both today's and tomorrow's complex applications.
External control signals can be used to start or otherwise influence the execution of applications loaded in memory. For this purpose, the board is equipped with an additional 16-bit digital input and 16-bit digital output.
Control commands to the scan system are issued synchronously every 10 µs as 16-bit digital output signals.
The RTC® SCANalone can also be operated via a PC connected to the board's USB interface. In this mode, the RTC® SCANalone offers the same functionality as an RTC®4 control board.
The RTC® SCANalone software interface and hardware connection capabilities are largely compatible with those of the RTC®4 control board. All options offered for the RTC®4 PC interface board (e.g. 3D or processing on the fly) are also available for the RTC® SCANalone.
Digital Encoder Technology
SCANLAB's digital encoder technology extends the company's fully digital iDRIVE® solution platform by providing highest dynamic performance with close-to-XY-stage precision, as well as comprehensive position feedback and process monitoring. This enables applications that require both high precision and high throughput, a property mix unachievable with previous scan systems or other beam-positioning technologies.
Digital encoders are integrated into SCANLAB's dynAXISde® galvanometer scanners, intelliSCANde® scan systems and varioSCANde® dynamic focusing units. Special care has been taken to ensure that use of digital encoders (even for a mid-size aperture of 14 mm) will enhance positioning precision without compromising dynamic performance or mechanical dimensions.
SCANLAB's first XY scan systems to feature digital encoders are the intelliSCANde®14 and intelliDRILLde®20. Their dynAXISde®M galvanometer scanners equal or exceed the high dynamic performance of the industryproven dynAXIS®M (with analog position detectors). They enable laser scanning with a positioning resolution of 19-20 bits, exceptionally low dither (electronic noise), best linearity and lowest drift. An SL2-100 interface facilitates comprehensive 20-bit control via SCANLAB's RTC®5 control board or RTC®5 PC/104-Plus board. Line pitch can be precisely adjusted for scribing applications and to eliminate effects such as Moiré patterns.
Applications that require a small-spot-size laser focus precisely positionable within a large processing area (e.g. photovoltaic manufacturing or rapid prototyping) will typically use short-wavelength DPSS or single-mode IR lasers and large-aperture scan systems. The short-Rayleigh-length characteristic for such systems raises the need for high focus-positioning resolution in the third dimension, too. varioSCANde® dynamic focusing units meet this requirement. Here, SCANLAB's digital encoder technology helps optimize precision, speed, resolution and linearity, while substantially reducing drift effects. Additional SCANLAB digital-encoder-equipped scan systems with high-end capabilities will primarily include the intelliSCANde®20, 25 and 30, as well as the intelliDRILLde®30.
