B.1.1 Interface Board Features
• Power Connection—Power is supplied to the Interface Board either from the PC via
the USB connection or through a power supply jack, J6. A chip at U4 disconnects the
USB power supply from the rest of the Interface Board when power is supplied through
jack J6.
Users providing their own power supply should ensure that it delivers +5 V DC at 10 W.
• Regulated Power Supply—The raw DC voltage is routed to a 3.3 V linear regulator.
The regulator provides stable power to the RCM5600W module and other boards con-
nected to it.
• Power LED—The power LED lights whenever power is connected to the Interface
Board.
• Reset Switch—A momentary-contact, normally open switch is connected directly to the
RCM5600W’s /RESET_IN pin. Pressing the switch forces a hardware reset of the system.
• mini USB Connector—A USB cable is used to connect the RCM5600W via the Inter-
face Board to your PC to enable you to program your RCM5600W module.
• mini PCI Express socket—The Interface Board provides a 52-pin mini PCI Express
socket to enable you to install your RCM5600W module. There is a snap-in holder to
hold the opposite end of the RCM5600W module firmly in place.
• I/O Switch and LED—One momentary-contact, normally open switch is connected to
PD1 on the RCM5600W module and may be read as an input by sample applications.
One LED is connected to PD0 on the RCM5600W module, and may be driven as an
output indicator by sample applications.
