Mesa 4I67 Info Sheet

MESA 4I67 INFO SHEET

The 4I67 is a PC/104-PLUS to dual Mini-PCI III adapter. The
4I67 allows two Mini PCI type III cards to be connected to a PC/104­PLUS system. Since the 4I67 uses a PCI-PCI bridge, it only uses
one PC/104-PLUS slot.

SETUP:

There are only 2 option jumpers on the 4I67, W1 and W2.
These select the PC/104-PLUS "SLOT" number that the 4I67
occupies.

W1 W2 PC/104-PLUS SLOT
DOWN DOWN 0

DOWN UP 1
UP DOWN 2
UP UP 3 (Only newer CPUs support slot 3)

The 4I67 has two independent local 3.3V power regulators
(U6,U7), one for each Mini-PCI card. Maximum current supplied by
the regulator is 1A per Mini-PCI card.

The 4I67 has 4 status LEDS and a connector (P1) to allow remote
LEDS to be connected. P1 is a 10 pin 2mm connector. P1 pin-out is
as follows:
PIN
1 Green0+
2 Green0­3 Yellow0+
4 Yellow0­5 Green1+
6 Green1­7 Yellow1+
8 Yellow1­9 GND
10 3.3V

External LEDS connected to P1 must have series current limiting
resistors.
