Xtreme/104-Plus 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-Plus or Xtreme/104-Plus Opto adapter
One CD containing software and documentation
One DB-9 male fan-out cable (optional)
If any of these components is missing, contact Connect Tech (see more Contact Details) or your
reseller.
There are three stages to installing your Xtreme/104-Plus:
10
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 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.)
Revision 0.04
Connect Tech Xtreme/104-Plus User’s Manual
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 Installation
Installing Xtreme/104-Plus cards into your system
Turn off the power to your computer and open it to expose the expansion slots (consult your
system’s documentation for more information on this procedure).
Choose an available position in the PC/104-Plus stack, and set the ID jumpers or rotary switch
accordingly (see ID Selection). Insert the Xtreme/104-Plus adapter and re-assemble the stack.
Hardware Configuration
Interrupts and Memory Address Selection
Xtreme/104-Plus boards are PCI cards, so the host computer’s BIOS will automatically set
interrupts and memory addresses when you reboot after installation.
Revision 0.04

Connect Tech Xtreme/104-Plus User’s Manual
ID Selection
Up to four Xtreme/104-Plus boards can reside within a single PC/104-Plus module stack. Each
card within the stack must have a unique ID ranging from zero to three.
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.)
CPU
0
1

3
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 that ID as well.
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 5 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:

ID Selection using the Jumper Block
If your Xtreme/104-Plus card is equipped with a jumper block for ID selection, set your board’s
location by changing jumper positions. Figure 6 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,
right jumper for an ID of two, and populate both for an ID of three.

Electrical Interfaces (RS-232/422/485 and RS-423 models)
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.
RS-422/485 Electrical Interface
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 7 to see examples of jumper settings.)
Full Duplex Mode
In this mode, TxD+/- & 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. It is the default setting.
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 PCI UART. Click on Advanced under
Port Settings after the driver is installed.
Multi-drop Slave 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
PCI UART. Click on Advanced under Port Settings. (See Half Duplex Mode above.)
Line Bias/Termination
The RS-422/485 transceivers, both transmit and receive are optionally biased to produce a line
level mark condition through jumper selectable resistors. These options are typically used in
multi-drop 4-wire connections.

Jumper Block Settings
The following jumper block diagram depicts typical settings on a four-port selectable
Xtreme/104-Plus or Xtreme/104-Plus Opto. Jumper blocks JA, JB, JC and JD control ports 1
through 4, respectively.

In this example, port 1 is set to RS-232, port 2 is set to RS-422/485 half duplex, port 3 is set to
RS-422/485 full duplex, and port 4 is set to RS-422/485 multi-drop slave.
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.
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
its own data as it sends. 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 150 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. The two jumpers for RxD termination/bias must be installed and removed as a pair.
TxD ± Termination: Install this jumper to enable a 150 ohm resistor across the TxD+ and TxDpins of the corresponding port.
Important port numbering note:
Due to differences between the quad and octal UARTS, the port numbering
for eight port models differs from the numbering for four port models.
Jumper blocks JA through JD control ports 1 through 4, respectively, on four
port models.
On eight port models, jumper blocks JA through JD control the odd numbered
ports and JE through JH control the even numbered ports, as follows:
JA = Port 1, JB = Port 3, JC = Port 5, JD = Port 7
JE = Port 2, JF = Port 4, JG = Port 6, JH = Port 8.
Half Duplex and Multi-drop Slave modes require you to select the appropriate
mode via software. Please refer to the readme.txt files found in the appropriate
directories on the Xtreme/104-Plus CD.

Electrical Interfaces (RS-232/422/485/TTL models)
RS-232/TTL Electrical Interface
The following control signals are available to ports configured for RS-232 and TTL mode: TxD,
RxD, RTS, CTS, RI, DTR, DSR, DCD, SG (Signal Ground) and +5V. See Figure 3 for the
location of Px1 RS-232/TTL port headers. See Figure 12 for information on configuring ports
for RS-232 or TTL mode. (Note: Current draw on +5V pins of all ports must not exceed 1 Amp.)
RS-422/485 Electrical Interface
In this mode, the port will communicate in RS-422 and RS-485 full duplex using the vertical
Px2 headers. (See Figure 3 for the location of Px2 headers). The following control signals are
available: TxD+/, RxD+/ and SR (Signal Return). See Figure 12 for information on configuring
ports for RS-422/485 mode.
Jumper Block Settings
The following jumper blocks correspond to the following ports:
JA = Port 1
JE = Port 5
JB = Port 2
JF = Port 6
JC = Port 3
JG = Port 7
JD = Port 4
JH = Port 8
The pin functions are outlined in the following diagram:
Figure 12: Examples of various jumper block settings for RS-232/422/485/TTL models
Revision 0.04
21
Connect Tech Xtreme/104-Plus User’s Manual
In the example in Figure 2, port 1 (JA) is configured for RS-422/485 full duplex, port 2 (JB) is
configured for RS-232, port 3 (JC) is configured for TTL, and ports 4 to 8 (JD to JH) are
disabled.
When all jumpers are removed, the corresponding ports are completely disabled. The UART will
receive no data from these ports, even if an external source is driving the headers.
NOTE: There are eight solder jumpers on the back of the board that
correspond to the vertical (Px2) headers on the front of the board. (See
Figure 3 for location of Px2 headers). If necessary, you can ensure TxD+/- pins
on specified vertical headers remain active, even if the board is not in RS422/485 mode or is disabled, by shorting the appropriate jumper.
