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.
