Connect Tech Xtreme/104-Express User Manual
Introduction
Connect Tech's Xtreme/104-Express multi-port serial boards provide a fully compliant PCI/104Express communications solution for industrial and embedded needs.
Xtreme/104-Express features a built-in baud rate prescaler to allow almost any non-standard
baud rate to be matched with a high level of accuracy. The onboard fail-safe 1/8th load
transceivers allow up to 256 devices on a multi-drop RS-485 bus. Filtering on all ports help
improve immunity to EMI and noisy transmission lines for guaranteed dependability in
communications.
The Xtreme/104-Express is perfect for military, aerospace, medical, instrumentation and
industrial control applications, among others. Full industrial temperature range (-40°C to 85°C)
operation is standard.

Xtreme/104-Express Installation Overview
Before you begin, take a moment to ensure your package includes the components that ship with
your product. These components should include:
One Xtreme/104-Express adapter
One CD containing software and documentation
DB-9 male fan-out cables (optional)
If any of these components are missing, contact Connect Tech or your reseller.
There are three stages to installing your Xtreme/104-Express:
1.
Hardware Configuration
Interrupts and memory selection will be set by the host computer’s BIOS and operating
system. This section outlines jumper settings and configuration.
2.
Hardware Installation
Installation involves the physical installation of the Xtreme/104-Express into your
computer. Please note that you should configure any jumper settings prior to installing
the board.
3.
Software/Driver Installation
Load the appropriate driver for your operating system, as found on the accompanying
CD. Installation guides are also available on the CD to aid you in this process.
Hardware Configuration
Interrupts and Memory Address Selection
The Xtreme/104-Express board is a PCI/104-Express card, so the host computer’s BIOS will
automatically set interrupts and memory addresses when you power up the system. Depending
on the operating system you are using, the operating system may opt to re-configure the devices.
Electrical Interfaces
RS-232 Electrical Interface
This is the default setting for the selectable interface of the Xtreme/104-Express. To operate a
port in RS-232 mode, no jumpers are installed on the corresponding jumper block.
RS-422/485 Electrical Interface
Xtreme/104-Express models offer three modes of RS-422/485 communication, as outlined
below. (See Figure 2 to see examples of jumper settings.)
Full Duplex Mode
In this mode, TxD+/- is being driven to a known level all the time. This mode is typically used in
point-to-point situations much like RS-232. It is the default setting for RS-422/485 mode.
8
Revision 0.00
Connect Tech Xtreme/104-Express User Manual
Half Duplex Mode
In this mode the TxD+/- line driver is enabled only when data is transmitted and RxD+/- is
disabled when data is being transmitted. This mode is typically used in either point-to-point 2wire connections OR in multi-drop 2-wire bus connections. This mode requires software setup
in Control Panel – System – Hardware – Device Manager – Ports – CTI Xtreme/104 PCI Express UART Serial
Port.
Multi-drop Mode
In this mode the TxD+/- line driver is enabled only when data is transmitted and RxD+/- is
enabled all the time. This mode is typically used in multi-drop 4-wire connections. This mode
requires software setup in Control Panel – System Properties – Hardware – Device Manager – Ports – CTI
Xtreme/104 PCI Express UART Serial Port.
Line Bias/Termination
The RS-422/485 transceivers can be configured to terminate and produce a line level mark
condition on the receiver, and/or terminate the transmitter. These options are enabled through
on-board jumper selectable resistors. These options are typically used in multi-drop 4-wire or
half duplex 2-wire connections.
Jumper Block Settings
The following jumper block diagram depicts typical settings on an interface-selectable
Xtreme/104-Express. (See Figure 1 for location of jumper blocks.)

Figure 3: Example port configuration jumper block settings
NOTE: The example above illustrates the following:
Ports 1, 2, 3 and 4 are configured for RS-485 Half-Duplex
Ports 5 and 6 are configured for RS-485 Multi-Drop Slave
Ports 7 and 8 are configured for RS-232
RS-485 Selection: Install this jumper to configure a port for RS-422/485 mode. If the jumper is
not installed, the port will function in RS-232 mode. All jumpers should be removed from any
port operating in RS-232 mode.
TxD Control: Install this jumper to enable the RS-485 transmitter only when sending data. This
mode is useful for half-duplex operation when only one device is allowed to send data at a time.
If the jumper is not installed, the transmitter will always drive the line to an idle state when not
sending data.
RxD Control: Install this jumper to enable the RS-485 receiver only when NOT transmitting
data. This is useful for half-duplex operation to prevent the transmitting device from receiving
the data it has sent. If this jumper is not installed, the receiver is always enabled and ready to
receive data.
RxD ± Termination/Bias: Install this pair of jumpers to enable a 120 Ohm terminator across the
RxD+ and RxD- pins for the corresponding port. A biasing network is also enabled that drives
the receiver to an inactive or safe mode. The receiver can still receive data from another device
and the biasing helps to prevent the reception of data generated by noise on the transmission
line, or a disconnected line. The two jumpers for RxD termination/bias must be installed and
removed as a pair.
TxD ± Termination: Install this jumper to enable a 120 Ohm resistor across the TxD+ and
TxD- pins of the corresponding port.
10
Revision 0.00
Connect Tech Xtreme/104-Express User Manual
Half Duplex and Multi-drop modes require you to select the appropriate mode
via software, appropriate wiring and the proper jumper block settings. Please
refer to the wiring recommendations (Figure 4) and the readme.txt files found in
the appropriate directories on the CD.
Tri-state Operation
Xtreme/104-Express models offer a power-on tri-state option to ensure glitch-free network
operation while the system is powering up. If enabled, the Xtreme/104-Express will tri-state the
transmitter until the driver opens the port. This operation is configurable for any port configured
as RS-485, regardless of the RS-485 mode selected.
Jumper J1 controls the power-on tri-state functionality. Install a jumper on the first location of
the J1 in order to tri-state Port 1 at power-on. Install a jumper on the second position for Port 2,
etc. The ports will not come out of tri-state until the operating system driver begins transmitting
on the associated port.
Installing a jumper on J1 will have no effect on ports configured in RS-232 mode.
