STATICELECTRICITY
The CMOS integrated circuits on the 4I60 can be damaged by exposure to electrostatic
discharges. The following precautions should be taken whenhandling the 4I60 to prevent possible
damage.

INTRODUCTION
GENERAL
The 4I60 is a high performance PCI 100BaseT Ethernet card in a PC/104-PLUS form factor.
PC/104-PLUS is a new embedded system card format that adds a stackable PCI connector to the
PC/104standard.
The 4I60 is a bus mastering PCI Ethernet card using the Digital Semiconductor 21143 Ethernet
chip. Thebusmasteringarchitecture ofthe21143 minimizes CPUinvolvement inpacket transmission
and reception. The large receive and transmit FIFOs permit efficient operation even with high
system latencies. The 21143 chip was chosen for its high performance, advanced feature set, and
widerangeofavailabledrivers.
The 4I60 supports full autonegotiation for automatic selection of all twisted media types. Full
duplex operation is supported on 100BaseT and 10BaseT modes. The 4I60 is a universal type
PC/104-PLUS card and will work with 3.3V and 5V bus systems. Only 5V power is required by the
4I60 (+12V is usedonlyfor theAUI connector) Unused circuitryispowered down whennot needed,
includingthe oncard DC-DCconverter. The 100BaseT interface ofthe PHY ispowered down when
using10BaseT.
All options are software selectable except the PCI slot number. A MII compatible connector is
available for use with other media types. A socket for a 32 pin boot ROM of up to 256K bytes is
provided. 5V flash ROMs, can be used, simplifying software upgrades. Various 4I60 options are
available including a lower cost and lower power 10BaseT only model. A low cost external panel
mount transceiveroptionisavailablefor10Base2(BNC) operation.

HARDWARE CONFIGURATION
GENERAL
The4I60has onlyone hardwareconfiguration options,thePCI slot number.ThePCI slot number
option is selected with shorting jumpers placed on three pin headers. In the following discussions,
when the words "up", "down" are used it is assumed that the 4I60 card is oriented with its ISA bus
connectorsJ1andJ2at thebottomedgeofthecard(nearest thepersondoingthe configuration).

PC/104-PLUS
The 4I60 is a PC/104-PLUS, PCI only card. This means that even though the PC/104 ISA
connector are present, the ISA signals are not used at all on the 4I60. The 4I60 will only work on
PC/104-PLUSCPUs!

HARDWARE CONFIGURATION
PCI SLOT SELECT
The onlyhardware selectable option on the 4I60 is the PCI slot number. This isthe equivalent to
choosing the motherboard slot a standard PCI card is installed into. The slot number also determines
the PCI interrupt line driven bythe 4I60. Jumpers W3 and W4 determine the PCI slot number: Each
card in the PC/104-PLUS stack must have a different slot number selected. Some PC/104-PLUS
CPUs do not haveall4 slots available for PC/104-PLUS add-incards. Notethat PCI DMAchannel2
isshared byslots 3 and 4. Since the4I60 is a busmaster card it cannot be used in slot 3 if another bus
master cardisinstalled inslot 4and vice versa.

INTERFACE CONNECTORS
100/10BASET CONNECTOR
The 4I60 may has a 8 pin modular telephone type jack for use with 100/10BaseT twisted pair
networks. This connector is marked P4. When twisted pair networks are used, a 100BaseT or 10
BaseT hubmust besupplied. You cannot ingeneralsimplyconnect fromoneinterface cardto another
when twisted pair cable is used.
AUI CONNECTOR
An AUI connector (P3) is provided for connecting to external 10 MBPS transceivers. This
connector is a 16 pin header. Whena flat cable with a female header at one end, and a female D-SUB
connector at the other end is plugged onto the 16 pin header, the D-SUB pinout matches the AUI
standard pinout. This flat cable is availablefrom MESA. Ifyou makeyour own cable, note that pin 16
of the flat cable is not used. The flat cable should be less than one foot long, as it is not a good
impedance match to the 78 Ohmtwisted pair transceiver cables. 12V power on the AUI connector is
directly connected to the PC/104 bus 12V system power. Selection of the AUI interface is a driver
option.
EXTERNAL 10BASE2 TRANSCEIVER OPTION
The 4I60isavailable with a low cost external10Base2 transceiver option.This panelmount BNC
transceiverallowssimpleexternalaccesstothe10Base2connectorwithoutdependingonthePC/104
stack location. This transceiver connects to the 4I60’s AUI connector with a 20 pinflat cable and gets
its isolated power from the 4I60’sDC-DC converter (P5). This flat cable must be 1 foot or shorter in
length . When installing the flat cable, make sure that the pin one mark on the cable is aligned with the
whitedotonconnectorP3. SelectionoftheBNCinterfaceisa driveroption.
MII CONNECTOR
A 44 pin 2MM connector is provided for connection to a MII paddle board. This connection
allows alternate high speed physical media interfaces to be attached to the 4I60. The paddle board
adapter is availablefromMESA.

INSTALLATION
GENERAL
When the 4I60 has been properlyconfigured for its application, it can be inserted into a PC/104-
PLUS stack. The standoffs should then be tightened to secure the 4I60 in its place. When the 4I60 is
securedinthestacktheI/Oconnectorscanbepluggedinfromtheside.
PC/104-PLUS
Again, the 4I60 is a PC/104-PLUS, PCI onlycard. This means that even though the PC/104 ISA
connector are present, the ISA signals are not used at all on the 4I60. The 4I60 will only work on
PC/104-PLUSCPUs!
POWER
The 4I60 gets all of its power from system +5V. +12V power will be required if an external
transceiver is used on the AUI connector. This does not apply to the MESA MAU 10Base2 interface
which gets its power from a DC-DC converter on the 4I60 card. The 4I60 can be used with 5V and
3.3VPCIbusCPUcards.Thisvoltageselectionisautomatic.
