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.
Hardware Installation
1. Turn your computer off and any peripherals connected to the computer (i.e.
Printers, external hard drives, etc.). Unplug the power cable from the rear of the
power supply on the back of the computer and disconnect all peripheral devices.
2. Remove the cover from the computer case. Refer to documentation for your
computer system for details.
3. Locate an open PCI or PCI-X slot and remove the metal cover plate on the rear of the
computer case.

connectors removed in Step 1.

Transmission Echo
This jumper determines if transmission data will be echoed back. The Echo mode is
useful to detect if the RS485 bus has data collision. If the echoed data is not equal to
the transmitted data, then there is collision. This setting only affects the RS485 2-wire
mode. It doesn’t affect RS485 4-wire, RS422 or RS232 modes.
