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 OFF ON OFF ON
Term ON OFF
Function 120 ohm Receiver Termination enabled Termination disabled
M1 OFF OFF ON ON
Serial Mode Loopback [1] RS232 RS485 (Half Duplex) RS422 (Full Duplex)
Slow Slew ON OFF
Function Slow Slew Rate enabled 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 PCIExpress 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.
