Introduction
The StarTech.com 4-Port ExpressCard to RS232 Serial Adapter Card
adds four DB9 RS232 serial ports to a laptop or ExpressCard enabled
desktop computer system. Based on a single-chip architecture (as opposed
to cards that use a “bridge chip”), thus providing native PCI Express
communication for greater performance and reliability, as well as reduced
power consumption and a CPU load reduction of up to 48%. Compatible
with ExpressCard/34 and ExpressCard/54 card slots, this card includes a
stabilizer bracket for greater security while installed in 54mm slots.

Installation
Hardware Installation
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.
NOTE: Some ExpressCard/54 slots do not firmly hold an ExpressCard/34
card so the 34mm to 54mm stabilizer bracket may be necessary.
