9 Introduction
Connect Tech's Xtreme/104-Plus, 104-PCI and 104/Express family combines the best of the
Universal PCI bus with the rugged and compact form factor of PC/104.
The various models are PCI 2.0, PC/104-Plus 2.0 or PCIe/104 compliant. The modular
Xtreme/104-Plus and Xtreme/104-Plus Opto cards include a PC/104 pass-through connector
option for compatibility with legacy PC/104 cards.
The Xtreme/104 family offer independent port configuration for baud rate, and data bit options
of 5, 6, 7 and 8, as well as, 1, 1.5 and 2 stop bits. Select between odd and even parity. The
Xtreme/104 Express offers a fractional baud rate generator which allows almost any baud rate to
be selected as well as a 9 bit addressing mode.
Connect Tech’s Xtreme/104-Plus and Express cards are perfect for embedded applications such
as, industrial PCs, kiosks, military systems, aerospace, medical systems, POS devices and any
system requiring fast data transfer speeds and a rugged, compact form factor. These self-stacking
cards are low on power consumption and function in industrial temperature conditions.

13 Xtreme/104 Installation Overview
Before you begin, take a moment to ensure your package includes the components shipped with
your product. These components should include:
•One Xtreme/104 adapter
•One CD containing software and documentation
•DB-9 male fan-out cable or DB9 male cables (optional)
If any of these components are missing, contact Connect Tech (see more Contact Details) or
your reseller.
There are three stages to installing your Xtreme/104:
1. Hardware Configuration
Interrupts and Memory selection will be set by the host computer’s BIOS. This section
outlines jumper settings and the ID selection process.
2. Hardware Installation
Installation involves the physical connection of the Xtreme/104-Plus or Xtreme/104
Express within your computer’s PC/104-Plus stack. (Please note that you should
configure any jumper settings, such as ID or electrical interface, if required, 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.
14 Hardware Installation
14.1 ESD Warning
Electronic components and circuits are sensitive to ElectroStatic Discharge (ESD). When handling
any circuit boards including Connect Tech PC/104 boards, 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.
14.2 Installing Xtreme/104-Plus or Xtreme/104PCI Cards Into Your System
Turn off the power to your system and open it to expose the PC/104 stack. Choose an available
position in the PCIe/104 or PC/104-Plus stack, and set the ID jumpers or rotary switch
accordingly (see ID Selection). Insert the Xtreme/104-Plus or Xtreme/104 Express adapter and
reassemble the stack.

15 Hardware Configuration
15.1 Safety note
To ensure the most reliable and safe operation, never install or remove jumpers or adjust the rotary
switch while the power is on!
15.2 Interrupts and Memory Address Selection
Xtreme/104 boards are PCI and PCI Express cards, so the host computer’s BIOS or Operating
System will automatically set interrupts and memory addresses when you reboot after
installation.
15.3 Xtreme/104 Plus and Xtreme/PCI-104 ID Selection
Up to four PC/104-Plus or PCI-104 boards can reside within a single PC/104 module stack. Each
card within the stack must have a unique ID ranging from zero to three.
(this section does not apply to PCIe/104 cards )
Depending on the model of your Xtreme/104-Plus adapter, you will
be required to set either a pair of jumpers or a rotary switch to
specify where your card is located within the stack. (Ensure that no
two boards share an ID number.)
In systems designed prior to the PC/104-Plus 2.0 specification, the fourth ID was reserved for
target only devices and did not support bus mastering. Since the Xtreme/104-Plus is not a bus
mastering device, we would recommend an assignment of ID 3. This leaves three of the IDs in
the PC/104-Plus stack available for bus mastering devices.
In systems designed post PC/104-Plus 2.0 specification, all four IDs support bus mastering, so
there is no advantage to setting the Xtreme/104-Plus ID to 3. Regardless of which PC/104-Plus
specification version the system is using, , the Xtreme/104-Plus will work with any ID selected
as long as no other device in the system is using the same ID.
15.3.1 Xtreme/104 Plus ID Selection Using the Rotary Switch
If your Xtreme/104-Plus or Xtreme/104-Plus Opto is equipped with a rotary switch, turn the
knob on the switch so that the arrow points at the ID you would like to use. (See Figure 6 for the
location of the rotary switch on the board). Use the following settings to set your adapter’s
location (or ID) within the stack:

15.3.2 Xtreme/104 Plus and /PCI-104 ID Selection Using the Jumper Block
If your Xtreme/104-Plus or Xtreme/PCI-104 card is equipped with a jumper block for ID
selection, set your board’s location by changing jumper positions. Figure 7 depicts the jumper
settings required for each ID.
The jumpers remain unpopulated for an ID of zero. Populate the left jumper for an ID of one, the
right jumper for an ID of two or populate both for an ID of three.

15.3.3 XIG 12 Port Opto Selection Using the Miniature Rotary Switch (Rev C/D)
The XIG 12 Port opto family is equipped with a rotary switch, turn the knob on the switch so
that the arrow points at the ID you would like to use. Use the following settings to set your
adapter’s location (or PCI ID) within the stack:

16 Electrical Interfaces Xtreme/104 Plus and Express
(RS-232/422/485 and RS-423 Models)
16.1 RS-232 Electrical Interface
This is the default setting for the interface selectable Xtreme/104-Plus and Xtreme/104-Plus
Opto. To operate a port in RS-232 mode, no jumpers are set on the corresponding jumper block.
16.2 RS-422/485 Electrical Interface
Xtreme/104 Express, Xtreme/104-Plus and Xtreme/104-Plus Opto RS-232/422/485 adapters
support three modes of RS-422/485 communication, as outlined below. (See Figure 8 to see
examples of jumper settings.)
16.2.1 Full Duplex 4-Wire Mode
In this mode, TxD+/- and RxD+/- are being driven to a known level all the time. This mode is
typically used in point-to-point situations much like RS-232. This is sometimes called RS-422
mode.
16.2.2 Half Duplex 2-Wire Mode
In Half Duplex 2-wire mode during transmission the TxD+/- line driver is enabled and the
RxD+/- is disabled. When the not transmitting, the TxD+/- is disabled and the RxD+/- is
enabled. The TxD+/- is disabled by tri-stating the output driver pins.
This mode is used in both point-to-point 2-wire connections and in multi-drop 2-wire bus type
connections. Special software setup is required so that the Xtreme/104 hardware automatically
performs the TxD and RxD enabled and disabling.
See the Driver Software Configuration section for software setup.
16.2.3 Multi-drop 4-Wire Mode
In this mode the TxD+/- line driver is enabled only when data is transmitted and RxD+/- is
enabled all of the time. This mode is used in multi-drop 4-wire connections. This mode is also
called “Multi-drop” slave.
See the Driver Software Configuration section for software setup.
16.2.4 Line Bias and Termination
The RS-422/485 transceivers, both transmit and receive can be optionally biased to produce a
line level mark condition through jumper selectable resistors. These options are typically used
in multi-drop 4-wire and 2-wire connections.
The RxD+/- features a combined Bias and Termination network.
The TxD+/- feature a single Termination resistor.
See the Jumper Block settings in the next section for more details.
