ESD Warning

Electronic components and circuits are sensitive to

ElectroStatic Discharge (ESD). When handling any circuit

board assemblies including Connect Tech COM Express

carrier assemblies, it is recommended that ESD safety

precautions be observed. ESD safe best practices include,

but are not limited to:

Leaving circuit boards in their antistatic packaging

until they are ready to be installed.

Using a grounded wrist strap when handling circuit

boards, at a minimum you should touch a grounded

metal object to dissipate any static charge that may be

present on you.

Only handling circuit boards in ESD safe areas, which

may include ESD floor and table mats, wrist strap

stations and ESD safe lab coats.

Avoiding handling circuit boards in carpeted areas.

Try to handle the board by the edges, avoiding contact

with components.

Introduction

The Mini PCI Express offers dependability and high speed data transfer rates in a very small form factor - Mini PCI

Express card.

Available with 2 or 4 ports of RS-232/422/485 connectivity, these PCI Express x1 lane cards are compatible with

x1, x4, x8, x16 lane PCI Express slots. Bi-directional data speeds up to 20 Mbps (depending on the model, using

RS-422/485) ensure fast data acquisition and communications. Experience more responsiveness with full modem

control signals while reducing the load on your network.

Setup and Operation The USB 2-Port Non-Isolated and PCI-Express 2-Port Isolated models share the same configuration setting

mechanism.

Each Port has a 4-Position switch which sets the mode for the Port. Positions #1 and #2 set the primary mode

for the port. Positions #3 and #4 perform secondary setup functions.

The physical orientation of these switches is different for each model, however each uses the same type

of switch block.

The “ON” position is show here for switch position #1, others are “OFF”,

M0 M1 Serial Mode

OFF OFF Loopback [1]

ON OFF RS232

OFF ON RS485 (Half Duplex)

ON ON RS422 (Full Duplex)

Term Function Slow Slew Function

ON 120 ohm Receiver Termination enabled ON Slow Slew Rate enabled

OFF Termination disabled OFF Slow Slew Rate disabled

Notes:

1. Loopback mode connects TXRX / RTSCTS, DSR, RI / DTRDCD at the Line Interface device, and

can be used to test the board operation without the need to external wrap-back connectors.

2. The termination function only works in RS422 or RS485 modes.

3. Slow Slew Rate works in any mode except loopback. When Slow Slew Rate is enabled, the baud rate is

limited to about 250K bps in any mode. Slow Slew rate is used to limit EMI emissions.

RS485 (or Half Duplex) Mode Operation This mode requires that the RTS signal be enable (turned On) prior to data transmission, then disabled (turned

Off) in order to allow data reception. This can be handled autonomously by the UART if appropriate Driver

software is employed.

Typical Installation

Mini PCI-Express Card Installation Most Mini-PCIe connector vendors (or system vendors) specify an “installed” space as either dimension A or

B in their drawings (or manuals).

Dimension A is from the surface of the system board to the centerline of the Mini-PCI-Express Card.

Dimension B is from the surfaces of the two cards. B is always 0.5mm smaller than A, because Mini PCI-

Express Cards are always 1mm thick.

The Connect Tech Mini PCI-Express Card Serial products have components and protrusions on the back side

of the card which require that they be installed in Mini PCI-Express card sockets which provide Dimension B

of 2.3mm or greater. Also, if there are any components on the system board, under the Mini PCI-Express Card,

then extra space may be required.

CAUTION: Always check whether any part of the Mini PCI-Express card is touching the system board and/or

components on the system board before powering the system. Failure to do so may result in damage to the

Mini PCI-Express card or the system.

Cable Attachment Certain models of these products have a “MiniTek” style latching connector for attachment of the interface

cable. The plug on the cable is keyed so it will only go into the connector one way.

To attach, push the cable into the board connector until a small “click” is heard (or felt). Once installed the

latch holds the cable to the board connector.

To release the cable, squeeze (and hold) on the edge of the clip and then pull the cable away from board

connector.

Software

USB Host Interface Products The products which use the USB Host interface use the FTDI FT2232 USB/Uart device. There are two

different types of Drivers available on the FTDI website for this device. The “VCP” (or Virtual COM Port)

Driver is most commonly used.

http://www.ftdichip.com/Products/ICs/FT2232H.htm

PCI-Express Host Interface Products The products which use the PCI-Express Host interface use the Exar 17V352 Uart device. The Connect Tech

BlueStorm/Express (Windows) Driver is available which will recognize and operate the Uart on this product.
