QM2000 board |
Award-winning capabilitiesThe QM2000 has its own VL-RISC/DSP microprocessor, the Motorola
ColdFire, and its own on-board memory. In fact, it is so sophisticated, the
host PC computer is used primarily for hard drive storage. The QM2000 can even
work outside of a PC, as a standalone computer (such as in the
Lasershow Player CD-ROM
playback device.) Board descriptionOn the left side of the QM2000 board, you can see the two output connectors:
At the top is the memory module. You can have only one memory module at a time; this card can have a capacity of up to 1GB RAM! Note that the QM2000 uses single-sided memory modules. You could use double-sided memory, but since the QM2000 addresses only one side, you'll lose half the memory capacity. Also, we recommend only certain types (brands) of memory which have been tested by Pangolin. For these reasons, it is best if you purchase memory through Pangolin -- it is guaranteed to be fully compatible, and you'll be able to use all the RAM you pay for. Click here for more information on the memory modules. On the right side is the Expansion connector. This allows the functions of the QM2000 to be expanded by connecting additional hardware. One example is a special network adapter board made by Pangolin, which allows the QM2000 to be connected over a network. Another example is that the QM2000 can be connected directly to a standard CD-ROM player. In the middle is the security hologram, located on the PCI controller chip. Each hologram has the serial number of the board. This lets you develop shows and frames that can be accessed only from specified boards (i.e., you specify which serial numbers can play the shows and frames). The board is well-protected by the long row of resistors you see between the output connectors and the rest of the board. This will make the QM2000 more robust than previous laser controller boards. Optoisolators are not needed on the QM2000.

The
QM2000 board is the heart of the LD2000 system. The LD2000 software cannot run
without this powerful computer-on-a-board being installed into the
PCI bus on a host PC, or located somewhere on an Ethernet network. The host can be either a desktop computer or a
QM2000 designed by expertsPangolin's
William R. Benner Jr., designer of the
QM2000, is an expert on the Motorola ColdFire. In fact, the ColdFire
Applications Team has published his 20-page application note, in order to
to help other designers (including Pangolin competitors!) using ColdFire processors.
