Titan/cPCI Software
To install your Titan/cPCI adapter under different operating systems see Software Installation.

Titan/cPCI User’s Manual, Connect Tech Inc.
Revision 1.01 9
Installing the Titan/cPCI adapter in your system
Titan/cPCI and Rear I/O adapters
To install your Titan/cPCI or Rear I/O adapter in your computer follow these steps:
1. Turn off the power to your computer.
2. Remove the Titan from its packaging, and remove the protective rubber from the alignment
pins on the Titan’s front panel.
3. Insert your Titan/cPCI into an available front 3U slot or insert your Titan/cPCI Rear I/O
adapter into an available rear 3U slot. The black handle on the front panel should be on the
bottom, in the lowered position.
4. Push the Titan into the cPCI slot until the handle mates with the card cage. Lift the handle to
lock the Titan into place.
5. With a screwdriver, fasten the screw on the top of the panel into the card cage for added
mechanical security.
Your Titan/cPCI and Rear I/O adapters are very sensitive to static
electricity. Make sure you wear an anti-static wristband before you
remove the card from the anti-static shipping bag. When you remove
the board from the anti-static bag, handle it only by the edges and
place it on the anti-static bag or an anti-static mat.

Titan/cPCI User’s Manual, Connect Tech Inc.
10 Revision 1.01
Configuring the Titan/cPCI
Compact Peripheral Component Interconnect (cPCI) bus architecture offers a feature called Plug
and Play (sometimes referred to as PnP). This feature automatically identifies and configures
installed devices each time the system boots.
In most CompactPCI compliant computers, the system BIOS will automatically detect and
configure the Titan/cPCI adapter. However in some cases a system BIOS cannot resolve all of
the requests for resources in the system. This often occurs with the assignment of system
interrupts, since this is usually the scarcest resource.
If this occurs, the driver will signal that a given resource has not been assigned, which requires
the user to assign system resources manually. After reboot, determine with the BIOS setup
utility what resources have been assigned to the cPCI devices and then do manual assignments
of free resources to your cPCI device. Reboot your system. If the BIOS cannot find a suitable
configuration please contact Connect Tech Technical Support.
Important Configuration Note:
The Titan/cPCI and the Titan/cPCI with front LEDs must be configured
for RS-485 to operate with the Titan Rear I/O Opto. This is configured
via jumper blocks on the Rear I/O Opto. You must remove ALL
jumpers on the front I/O Titan/cPCI when you are using the Rear
I/O Opto.
Baud Rate Selection
Titan/cPCI adapters offer ideal solutions for applications requiring serial communications up to
1.8432 Mbps. Baud rates are software selectable; please refer to Software Installation for
configuring the baud rates under certain operating systems.
RS-422/485 Line Interface
The Titan/cPCI adapters and Rear I/O Opto adapters come with a jumper selectable RS-422/485
electrical line interface for each port. The RS-422/485 electrical interface is a reliable high-
speed serial link that offers superior noise immunity and multi-drop network connectivity. The
RS-485 electrical interface is also a superset of the RS-422 electrical interface. Titan/cPCI and
Titan/cPCI Rear I/O Opto adapters offer full RS-422/485 support in hardware. The following
modes are supported:
Full Duplex Mode
In this mode, TxD & RxD are active all the time. This mode is typically used in point to point
situations much like RS-232. Please refer to Appendix D: RS-422/485 Line Interface for the
jumper settings associated with this function.
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 "2 wire"
connections OR in multi-drop "2 wire" bussed connections. Please refer to Appendix D:
RS-422/485 Line Interface for the jumper settings associated with this function.

Titan/cPCI User’s Manual, Connect Tech Inc.
Revision 1.01 11
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. Please refer to
Appendix D: RS-422/485 Line Interface for the jumper settings associated with this function.
Line Termination
You can terminate and bias TxD +/-, RxD +/-, RTS +/-, and CTS +/- on the individual
RS-422/485 ports through jumper selectable 150 Ω fixed resistors. Please refer to Appendix D:
RS-422/485 Line Interface for the jumper settings associated with this function.
Software Installation
Introduction
Titan/cPCI boards are standard multi-port serial adapters that utilize 16C950 UARTs. In many
cases, users have software that will interface directly to the Titan/cPCI boards. Many operating
systems come with handlers to control access to multiple 8250 style UARTs. Titan/cPCI
adapters currently ship with device drivers for the following operating systems:
QNX 4
QNX 6
Windows NT
Linux
Before installing the Titan/cPCI software device driver, verify and note jumper settings
described in Appendix D: RS-485/422 Line Interface for:
Jumper block JA – Full duplex, half duplex and multi-drop slave control
Jumper block JB – RS-232, RS-485/422 select
Jumper blocks JC, JD, JE and JF – line bias/termination.
If you require further information please contact Connect Tech Technical Support.
Technical Tips:
Your Titan/cPCI adapter may ship with diskettes that include 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 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.
