Installation
WARNING! PCI cards, like all computer equipment, can be severely damaged
by static electricity. Be sure that you are properly grounded before opening
your computer case or touching your PCI card. StarTech.com recommends
that you wear an anti-static strap when installing any computer component. If
an anti-static strap is unavailable, discharge yourself of any static electricity
build-up by touching a large grounded metal surface (such as the computer
case) for several seconds. Also be careful to handle the PCI card by its edges
and not the gold connectors.
Jumper Settings
The two sets of jumpers on this card (J4, J3 and PORT1_RT, PORT2_RT) are
used to configure the operating mode/serial protocol and 2/4-wire operation
respectively.
