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 o 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.

Instruction Manual

4. Set the jumpers on the card to the desired conguration. See “How to Use”section

for jumper descriptions.

5. Insert the card into the open PCI or PCI-X slot and fasten the card’s bracket to the

rear of the case.

6. Place the cover back onto the computer case.

7. Insert the power cable into the socket on the power supply and reconnect all other

connectors removed in Step 1.

RS232

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 aects the RS485 2-wire

mode. It doesn’t aect RS485 4-wire, RS422 or RS232 modes.

JP2 (for S1 port)/JP5 (for S2 port) Description

No data echo.

(Default)

Transmission data will be echoed

Instruction Manual

Termination Resistor

This jumper enables/disables the 120 Ohm termination resistor between DATA+ and

DATA- of the RS485 transceiver:

JP2 (for S1 port)/JP5 (for S2 port) Description

Termination Resistor Disabled

(Default)

Termination Resistor Enabled

NOTE: All other headers and jumpers on the card that are not documented, should not

be altered/used.
