Introduction
The EC2S55254 2-Port Native 54mm ExpressCard RS232 Serial Adapter
Card and EC1S1P55254 1S1P 54mm ExpressCard Serial Parallel Card

cable features a 256 byte transmit/receive FIFO buffer and supports baud
rates up to 128Kbps, with parallel data rates up to 1.5Mbps. A native chipset
provides reliability and performance improvements, as well as lower CPU
loads and power consumption over conventional bridge-chip serial cards.
Designed for use with laptop computers equipped with 54mm ExpressCard
slots, this serial card offers a broad operating system compatibility list
including Windows®, Mac OS X and Linux for simple integration into almost
any system.

Installation
Hardware Installation
Connect the included breakout cable to the card prior to installing the card.
This will prevent accidental disconnection of the card from trying to connect
the breakout cable after the card is installed.
NOTE: The connector on the EC1S1P55254 card will function as a standard
DB25 parallel port without the breakout cable. Connect the breakout cable if
the serial port is also required.
The ExpressCard adapter will simply slide into the ExpressCard slot on any
compatible system. Push the card all the way in, until it ‘clicks’ and locks into
place. To eject the card, simply push the card further into the slot until it clicks,
and then release and it will then be automatically ejected from the slot.
Turning the computer off to insert/remove ExpressCard adapters is not
necessary as they are hot-pluggable.
