Introduction
Xtreme/104 adapters are high performance multi-port serial adapters in a PC/104 form factor that
enable you to connect up to 8 serial devices to your PC-based system. They provide a high speed
interface between your host computer and multiple external serial devices
Features
●4 or 8 asynchronous serial ports.
●Hardware configurable RS-232 and RS-422/485 electrical interfaces. The interfaces are
jumper selectable for each port. (Xtreme/104 RS-232 adapters have an RS-232 only
electrical interface.)
●Multiple Xtreme/104; Xtreme/104 RS-232 adapters may reside in a system.
●16C654 quad UARTs control each port. The 16C654 quad UART has 64 byte TxD and
RxD FIFO buffers for each port and automatic software/hardware flow control.
●Each port has independent baud rate selection offering baud rates from 50 – 230.4 Kbps
(RS-232) and 50 – 460.8 Kbps (RS-422/485), with 5, 6, 7 or 8 data bits and 1, 1.5, 2 stop
bits, odd or even parity.
●On board jumpers allow the selection of 8 predefined I/O address sets.
●On board jumpers allow the selection of 1 or 2 IRQ lines. You can choose from interrupts 3,
4, 5, 6, 7, 9, 10, 11, 12, 14 and 15.
●Driver support for Windows 95/98/Me/CE/CE .NET/XP/XPe/NT/2000/. Also compatible
with operating systems featuring 16450/16550 serial drivers such as: Linux, BSD/OS, QNX,
DOS, Solaris, OS/2 (3RD party driver) and SCO Unix.

Hardware Installation
Before you begin, take a minute to ensure that your package includes the required components
that should have shipped with your Xtreme/104.
•One Xtreme/104 adapter or Xtreme/104 RS-232 adapter
•One CD containing software and documentation
•One DB-9 cable (optional)
If any of these components is missing, contact Connect Tech (See Contact Details) or your
reseller. Also, visit the Download Zone of the Support Center on the Connect Tech website for
the latest product manuals, installation guides, diagnostic utilities and device driver software.
Notes:
1. Please refer to the RS-232/ 422/485 Interfaces
section in the back of the manual for more
information concerning RS-232 and RS-422/485
settings for the Xtreme/104 adapter.
2. Please refer to the Factory Default Settings section
in the back of the manual concerning the factory
settings for the Xtreme/104 adapter.
Port Addresses
Port addresses are configured with the jumper block J1 or JB1 on the Xtreme/104 or Xtreme/104
RS-232 adapter respectively. Jumpers 0, 1, and 2 select a set of port addresses for the ports.
Status Port Addresses
Some operating system device drivers can utilize an Interrupt Status Port, for example Windows
NT offers it as an option and for SCO Unix it is mandatory. This can improve your system’s
efficiency. The Xtreme/104 and Xtreme/104 RS-232 offer a status port and this port is enabled
and disabled using jumper 5 on jumper block J1 or JB1.
Please refer to Table 1 for a list of supported status port addresses and to Figure 1 or Figure 2 for
a description and location of jumper block J1 and JB1.
Note:
Please make certain that the Status Port Enable jumper is
disabled if your application is not using the Status Port. This
eliminates the possibility of an address conflict with another
device in your system.
Custom Port Addresses
You can generate other port addresses by making changes to the CPLDs found on the
Xtreme/104 and Xtreme/104 RS-232 adapter. If you require specific port addresses not listed in
Table 1 please contact a Connect Tech Customer Service Representative for further information.

Interrupt Selection
You can configure an interrupt request line (IRQ) with jumper blocks J1 or JB1, AB and CD on
the Xtreme/104 and Xtreme/104 RS-232 adapter. Please refer to Figure 1 and Figure 2 to locate
jumper blocks J1, JB1, AB and CD.
You are able to configure the Xtreme/104 and Xtreme/104 RS-232 adapter for three different
IRQ modes.
Mode 1 (one IRQ):
1. Ensure there are no jumpers across positions 3 and 4 on the J1 or JB1 jumper block.
2. All ports interrupting on one IRQ by setting jumpers on the A or C rows and the middle
rows of IRQ blocks AB and CD.

Connect Tech Xtreme/104 User’s Manual
12 Revision 0.05
Mode 2 (two IRQs):
1. Jumper position 3 on the J1 or JB1 jumper block.
2. The odd ports (ports 1, 3, 5, & 7) interrupt on one IRQ by setting jumpers on the A or C
rows and the middle rows of IRQ blocks AB and CD.
3. The even ports (ports 2, 4, 6, & 8) interrupt on one IRQ by setting jumpers on the B or
D rows and the middle rows of IRQ blocks AB and CD.
Mode 3 (two IRQs):
1. Jumper position 4 on the J1 or JB1 jumper block
2. The first four ports (ports 1, 2, 3, 4) interrupt on one IRQ by setting jumpers on the A or
C rows and the middle rows of IRQ blocks AB and CD.
3. The last four ports (ports 5, 6, 7, 8) interrupt on one IRQ by setting jumpers on the B or
D rows and the middle rows of IRQ blocks AB and CD.

Baud Rate Selection
The Xtreme/104 is capable of baud rates up to 460.8 Kbps (4X oscillator) or 115.2 Kbps (1X
oscillator). The Xtreme/104 RS-232 is capable of baud rates up to 230.4 Kbps (4X oscillator) or
115.2 Kbps (1X oscillator). These baud rate limits depend on whether you install a shorting
block across position 6 on the J1 or JB1 jumper block. Please refer to Figure 1 and Figure 2 for
the location of jumper block J1 or JB1. Please refer to Table 2 for a list of standard and

Software Installation
Xtreme/104 adapters are standard multi-port serial adapters that utilize 16C654 quad UARTS.
In many cases, users have software that will interface directly to the Xtreme/104 adapters. Many
operating systems come with handlers to control access to multiple 16550 style UARTS. If you
require further information please contact Connect Tech Customer Support.
Technical Tips:
Your Xtreme/104 adapter may ship with a CD that includes
howto.txt or readme.txt files. Please examine these files for
technical tips or release notes concerning installation and
configuration of various device drivers and software utilities.
If you did not receive a driver diskette or CD for your operating
system or you require additional information, please go to the
Download Zone of the Support Center on the Connect Tech
website for product manuals, installation guides, diagnostic
utilities and device driver software.

Part Number: CAB8104
Technical Tip:
The red stripe on the CAB8104 cable indicates pin 1 on the 40 pin
header connector.
Please ensure that you terminate the DCD or CTS signals if your
application does not use them. The common way to do this is to
connect DCD to DTR and/or to connect CTS to RTS. Failure to do
so may result in a loss of a performance on your Xtreme/104;
Xtreme/104 RS-232 adapter.
