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.

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

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.
