Introduction

The PCI2S4851050 2 Port PCI RS422/485 Serial Adapter Card with 161050

UART adds two DB9 RS422/RS485 serial ports using a single PCI expansion

slot.

The serial card offers a high performance 16C1050 UART and is compliant

with PCI 2.3 local bus speciﬁcations. An efﬁcient single-chip design and a

large 256-byte transit/receive FIFO buffer work together to provide high-speed

serial communication while reducing the overall load on the CPU.

With the included standard and low proﬁle brackets, this PCI serial expansion

card suits a broad range of system form factors, and is a perfect addition for

connecting RS422/485 serial devices to a host computer. For added versatility,

the RS422/485 adapter is able to accommodate 3.3 or 5V PCI/PCI-X slots.

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.

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.

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

to the rear of the case.

NOTE: If installing the card into a small form factor/low proﬁle system,

replacing the pre-installed full proﬁle bracket with the included low proﬁle

installation bracket may be necessary. This conﬁguration will require two

adjacent expansion card slots in the host computer system.

5. Place the cover back onto the computer case.

6. Insert the power cable into the socket on the power supply and reconnect

all other connectors removed in Step 1.
