Legacy
DSP-based motion control architecture — the foundation of countless OEM machines for over three decades.
Upgrade Path
Migrate to the latest digital control technology. RSI's DSP-to-RapidCode translator allows C/C++ code written for the DSP series to be quickly compiled with RapidCode and run on modern SynqNet or EtherCAT hardware — or as a soft motion controller without dedicated hardware.
Important Note
DSP series motion controller cards were first introduced in 1989. Upon their introduction, the MEI boards became an instant success, allowing customers to achieve complex motion and I/O tasks on a wide range of machines. After more than 25 years, these cards are still being used successfully by customers around the world — a testament to their reliability and longevity.
Unfortunately, various components used to assemble the DSP cards have surpassed their end-of-life cycle, and Kollmorgen (who acquired MEI) has announced that they will discontinue manufacturing these boards.
Apart from being the exclusive reseller and providing technical support, RSI has been responsible for all DSP-series controller repair. Our goal is to keep serving customers beyond the EOL of DSP cards. RSI maintains a limited supply of EOL components to allow us to make repairs in the future.
RSI can offer several upgrade paths utilizing the latest technology — including SynqNet and EtherCAT — and our DSP-to-Digital translator to assist with code migration.

Legacy Cards
The 104/DSP combines MEI’s proven DSP-based motion control architecture with the compact, rugged design of the PC-104 bus interface.
Hardware features include 16- bit servo outputs, encoder inputs to 5 MHz, and 20 lines of user I/O.
You program the 104/DSP using MEI’s flexible C function libraries with over 250 motion control functions.
Combining MEI C libraries with compilers from Microsoft, Borland, Watcom, Symantec, and others speeds development of complex motion applications.
The 104X/DSP combines MEI’s proven DSP-based motion control architecture with the compact, rugged design of the PC-104 bus interface in an extended form factor (4.5″ x 6.5″) for OEM system designers.
The 104X/ DSP is ideal for OEM embedded motion control applications because it requires no expensive backplane or motherboard.
You program the 104X/DSP using MEI’s flexible C function libraries, with over 250 motion control functions.
MEI C libraries combine with compilers from Microsoft, Borland, Watcom, Symantec, and others to speed development of complex motion applications.
The DL-PCI offers excellent price and performance in a single-board motion controller. A powerful Analog Devices DSP provides up to 4 axes of servo or stepper control in a single PCI bus slot.
Hardware features include 16-bit servo outputs, encoder inputs to 5 MHz, and 20 lines of user I/O.
You program the DL-PCI using RSI’s flexible C function libraries with over 250 motion control functions. This library is fully compatible with existing code developed by Motion Engineering.
Combining RSI C libraries with compilers from Microsoft, Borland, GNU and others speeds development of complex motion applications.
The DL-PCI provides a rich set of software algorithms, including a sophisticated second-order PID control algorithm with velocity, acceleration, and friction feed-forward.
Advanced features include electronic gearing and camming, dual-loop control, circular and linear interpolation, and trapezoidal, S-curve, parabolic, and custom motion profiles.
The DL-PCI allows motion control programs to share execution between the on-board DSP and the host . This results in an ideal division of labor with minimal host intervention.
Note: <p>The DL/PCI and the PCI/DSP motion controllers require 5 volts over the PCI Bus. They are not compatible with the 3.3 volt PCI Bus. Please note that new PCs are phasing out the 5 volt PCI Bus in favor of the 3.3 volt PCI Bus. Check the PCI slot in your PC to verify that it is 5 Volt</p>
