the anti-static bag or an anti-static mat
Titan/cPCI User’s Manual, ver. 0.00
Chapter 2: Hardware Installation 2-1
Hardware Installation
Introduction
Hardware installation involves configuration of the following
Titan/cPCI products:
The Titan/cPCI-2 /cPCI-4 adapters
Configuration
Note: Please refer to Chapter 3: Software Installation for
installation of your Titan/cPCI board under certain operating
systems.
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.
Baud Rate Selection
Titan/cPCI adapters offer ideal solutions for applications
requiring serial communications up to 1.8432 Mbps. Baud rates
are software selectable, so therefore please refer to Chapter 3:
Software Installation for configuring the baud rates under
certain operating systems.
Titan/cPCI User’s Manual, ver. 0.00
2-2 Chapter 2: Hardware Installation
RS-485/422 Line Interface
The Titan/cPCI adapters come with a jumper selectable RS485/422 electrical line interface for each port. The RS-485/422
electrical interface is a reliable high-speed serial link that offers
superior noise immunity and multi-drop network connectivity.
The RS-485/422 electrical interface is also a superset of the RS422 electrical interface. Titan/cPCI adapters offer full RS485/422 support in hardware. The support is:
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-485/422 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-485/422 Line Interface for the
jumper settings associated with this function.
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-485/422 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-485/422 ports through jumper selectable 150
Ω fixed resistors. Please refer to Appendix D: RS-485/422 Line
Interface for the jumper settings associated with this function.

Chapter 2: Hardware Installation 2-3
Installing the Titan/cPCI Adapter in your System
To install your Titan/cPCI adapter in your computer follow these
steps:
Your Titan/cPCI adapter is 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.
1. Turn the power off 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 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.
4. With a screwdriver, fasten the screw on the top of the panel
into the card cage for added mechanical security.

Electrical Interface Selection
The Titan/cPCI adapter provides jumper selectable RS-232 and
RS-485/422 electrical interfaces on each port.
Jumper block JB sets the electrical interfaces for the individual
ports. Jumpers installed across the pins on jumper block JB
enable the RS-232 interface for that port, while jumpers not
installed across pins enable the RS-485/422 interface for that port.
Figure 1 shows the location of jumper block JB.

Technical Note:
You can set up the RS-232 serial ports to run at up to 230.4
KBPS, but you must use good quality serial cables with lengths
that do not exceed 2 metres

Full Duplex Mode
By not installing pins on jumper block JA and by using features
in our driver software, you can run the individual RS-485/422
ports in full duplex mode. This mode is typically used in point to
point RS-485/422 situations much like RS-232. In this mode,
TxD & RxD are active all the time. Figure 1 shows the location
of jumper block JA.
Half Duplex RS-485
By installing pins on jumper block JA and using features in our
driver software, you can run the individual RS-485/422 ports in
half duplex mode. In this mode your Titan/cPCI adapter controls
the transmitter and receiver circuits. DTR is turned on prior to
and during transmission to cause the transmit driver to enable and
the receiver to disable. DTR is turned off when not transmitting
to cause the transmit driver to disable (tri-stated) and the receiver
to enable. The 16C950 UARTs on the Titan/cPCI adapter are
responsible for timing the DTR toggle.
Multi-drop Slave Mode
By not installing jumpers on jumper block JA and by using
features in our driver software, you can run the individual RS485/422 ports in 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.
Example
The example below shows the settings on JA where RS-485
ports 1 and 2 are set for full duplex or multi-drop slave mode,
port 3 is set for half duplex and port 4 is not set since port 4 is
set for RS-232 on jumper block JB.

Technical Note:
Full duplex, multi-drop slave and half duplex modes apply to

RS-485/422 on jumper block JB.

Line Termination
You can use jumper blocks JC, JD, JE and JF to terminate and
bias TxD ±, RxD ±, RTS ±, and CTS ± on the individual RS485/422 ports through jumper selectable 150 Ω fixed resistors.
Please refer to Figure 4 for a partial schematic of the RS-485/422
circuit for the Titan/cPCI and to Figure 1 for the locations of JC,
JD, JE and JF.

Technical Notes:
1. For full duplex and multi-drop slave you can jumper
positions 1, 2, 3, 4, 5, and 6, on the appropriate jumper
block (JC, JD, JE or JF) if you want them terminated.
2. For RS-232 ports do not jumper positions 1, 2, 3, 4, 5, and
6, on the appropriate jumper block (JC, JD, JE or JF).
