RC10 Overview
2 RC10 Getting started
This section describes how to set up and start using your RC10.
2.1 RC10: System requirements
Using the Celoxica RC10 requires the following:
•DK Design Suite. Only required if you want to use the RC10 PAL and PSL libraries.
•Microsoft Windows 2000 or Windows XP for the FTU3 program and for use of the DK
Design Suite.
•Microsoft Visual Studio .NET in order to write applications on the host PC that interface with
the RC10.
2.2 RC10: Unpacking the board
You should take care to avoid static discharge when handling the RC10 board, as this may damage it.
You are recommended to use an earth strap. If an earth strap is not available, ensure that you make
contact with earth before and during handling of the board, and only handle the board by its edges.
2.3 RC10: Connecting the cables
The board must be powered down before you attach cables. The connectors are labelled on the board
and in the overview of devices and connectors.
You will need to connect the board to your PC with astandard USB cable if you want to use the Celoxica
FTU3 program to download FPGA configuration files, or to read from or write to Flash memory.
2.4 RC10: Switching on the power
The RC10 board can draw power from the host PC via the USB cable, or an optional external power
supply can be connected to connector CN18, which is of the type commonly used for PC hard disk
drives and CD/DVD drives.
Note that if you wish to use the servo motor connector (CN9), the 5V supplies on the ATA connector
(CN13) or the optional LCD panel with a backlight then an external power supply must be connected.
Peripheral devices should be connected before the RC10 board is turned on. Otherwise the devices
may not function correctly.
When turned on the 'Power' LED (D14) should illuminate.
2.5 RC10: Installing drivers
When the RC10 is plugged into a PC running Windows XP or 2000, the operating system will ask for
driver files to be supplied. These are installed by the PDK installer into the
PDKInstallDir\Software\Drivers\RCUSB directory. Once these are installed, the board is ready
for use. Running the FTU3 application will then allow you to access the board.
