IDE support
The single primary parallel ATA/IDE interface is directly accessible on the ISIS board
through a 44-pin header (J5) on the ISIS board. This gives the user the possibility to
connect an external hard drive or CD-drive to the ISIS board.
An LED is present on the ISIS-Breakout and signals access to the IDE bus.
Flash
The ISIS supports a soldered down solid state FLASH disk with boot support. This is
interfaced on the IDE bus and provides options for 2GB and 4GB NAND flash. The Intel
Z-P140 PATA solid state disk is used for this function.
PS/2 interface
Legacy PS/2 keyboard and mouse are supported on standard PC99 MiniDin connectors.
Serial ports
Serial port 1 is a full RS-232 interface port and is connected to the Eurotech TSC1 by
default (LCD variant only). If the user does not wish to use the serial touchscreen
controller, it is possible to connect serial port 1 directly to the upper SUBD9 male
connector on the ISIS breakout. A suitable cable is provided in the cable kit to do so.
Serial port 2 is a software selectable RS232/485/422 port and is accessible on a standard
SUBD9 male connector.
GPS receiver
An optional GPS module is used on the ISIS to provide complete GPS functionality
including position, velocity and time (PVT).
The Fastrax iTrax300 GPS module is based on SiRF GSC3e/LP single chip. More
information on iTrax300 can be found at:
Touchscreen controller
The ISIS development kit supports the Eurotech’s TSC1. The TSC1 is an analogue
resistive touchscreen controller that interfaces with the processor board via an RS232
serial port.
