CPU Board
Universal Serial Bus (USB)
The PC1-GROOVE is provided with twelve USB ports, all of them are USB 2.0 capable. Two USB
interfaces are routed to front panel connectors, two ports are feed to the expansion board interface
connectors J-EXP, four to the high speed expansion connector J-HSE, and four ports are available
across the J2/P2 connector for PlusIO.
The front panel USB connectors can source up to 0.5A/5V each, over-current protected by two
electronic switches. Protection for the USB ports on the expansion interfaces and on the PlusIO
connector is located on expansion boards like CCH-MARIACHI and the boards on the
CompactPCI
Serial backplane respective. The two USB EHCI controllers handling the USB ports are integrated into
the PCH.
Real-Time Clock
The PC1-GROOVE has a time-of-day clock and 100-year calendar, integrated into the PCH. A battery
on the board keeps the clock current when the computer is turned off. The PC1 uses a BR2032 lithium
battery soldered in the board, giving an autonomy of more than 5 years. Under normal conditions,
replacement should be superfluous during lifetime of the board.
In applications were the use of a battery is not permitted, a SuperCap can be stuffed instead of the
battery.
LPC Super-I/O Interface
In a modern system, legacy ports like PS/2 keyboard/mouse, COM1/2 and LPT have been replaced by
USB and Ethernet connectivity. Hence, the PC1-GROOVE is virtually provided with all necessary I/O
ports. However, for compatibility purposes the PC1 is equipped with the interface connector J-EXP to
the local LPC bus (LPC = Low Pin Count interface standard), which is a serialized ISA bus replacement.
EKF offers multiple expansion boards to the PC1-GROOVE, featuring all classic Super-I/O functionality,
for example the CCH-MARIACHI. Access to the connectors PS/2 (mouse, keyboard), COM, USB and
audio in/out is given directly from the front panel. The CCH-MARIACHI connects to the PC1-GROOVE
across the connectors P-EXPT or P-EXPB. Usually the CCH is attached to the top of the PC1-GROOVE.
Nevertheless bottom side mounting is possible on customers request.
SPI Flash
The BIOS is stored in two flash devices with Serial Peripheral Interface (SPI). 8MByte of BIOS code,
AMT firmware and user data may be stored nonvolatile in these SPI flashs (up to 16MByte of flash
space is available on request).
The SPI flash contents can be reprogrammed (if suitable) by a DOS or Linux based tool. This program
and the latest PC1-GROOVE BIOS binary are available from the EKF website. Read carefully the
enclosed instructions. If the programming procedure fails e.g. caused by a power interruption, the
PC1-GROOVE may no more be operable. In this case you would possibly have to send in the board,
because the flash devices are directly soldered to the PCB and cannot be changed by the user.
