dotLINK Personality board     The dotLINK personality board carries the electronics necessary for the operation of the dotLINK. This allows the processor board to function as it supplies necessary connections and power. The Ethernet chip is (the SMSC 91C111) is a non-PCI Ethernet Mac and PHY.  Connections  The dotLINK personality card has 6 serial ports, 1 Ethernet port, and 1 USB port.  Both the Serial ports and Ethernet ports use an RJ-45 connector. The USB connector  is a standard “A” type USB connector. The processor board is connected to the  dotLINK personality board by using a fine pitch board to board connector. Electronics  The dotLINK personality board has all necessary electronics including, Ethernet  MAC and PHY, Ethernet Magnetics, 6 UARTS, RS-232 drivers, and power supplies. Microprocessor  SH4 7760 highly integrated, 32-bit processor. This microprocessor has on-chip  peripherals ranging from serial ports, to USB, to an LCD controller.  Permanent Storage  The processor board has 32MB of flash in which to store the Boot loader, OS, and application.  Temporary Storage  There is 32MB of SDRAM on the card engine.  Ethernet  Ethernet is provided by an SMSC 91C111 non-PCI Ethernet MAC and PHY. This provides one port of switchable 10/100 Base-T Ethernet.  Serial  There are three serial ports that are integral to the processor.
