Titan/cPCI User’s Manual, Connect Tech Inc. You can combine different Titan/cPCI and Titan/cPCI Rear I/O adapters in a single computer to accommodate both small and large multi-channel applications. The figure below represents a sample configuration for a system requiring 10 ports.
Titan/cPCI User’s Manual, Connect Tech Inc. 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. 2. 3. 4. 5. Turn off the power to your computer. Remove the Titan from its packaging, and remove the protective rubber from the alignment pins on the Titan’s front panel.
Titan/cPCI User’s Manual, Connect Tech Inc. 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.
Titan/cPCI User’s Manual, Connect Tech Inc. 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.

Titan/cPCI User’s Manual, Connect Tech Inc. Appendix D: RS-422/485 Line Interface Titan/cPCI adapters Electrical Interface Selection The Titan/cPCI adapter provides jumper selectable RS-232 and RS-422/485 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-422/485 interface for that port.
Titan/cPCI User’s Manual, Connect Tech Inc. Full Duplex Mode (4 wire) By not installing pins on jumper block JA and by using features in our driver software, you can run the individual RS-422/485 ports in full duplex mode. This mode is typically used in point to point RS-422/485 situations much like RS-232. In this mode, TxD & RxD are active all the time. Figure 1 shows the location of jumper block JA.
Titan/cPCI User’s Manual, Connect Tech Inc. Line Termination You can use jumper blocks JC, JD, JE and JF to 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 Figure 7 for a partial schematic of the RS-422/485 circuit for the Titan/cPCI and to Figure 1 for the locations of JC, JD, JE and JF.

Titan/cPCI User’s Manual, Connect Tech Inc. Titan/cPCI Rear I/O Opto 2 and 4 port adapters • • • The four port Rear I/O Opto requires a four port Front I/O Titan to be installed. The two port Rear I/O Opto requires a two port Front I/O Titan to be installed. In either case, when using the Titan/cPCI Rear I/O Opto, the front I/O Titan/cPCI board must be configured for RS-485, with no bias or termination jumpers installed.
Titan/cPCI User’s Manual, Connect Tech Inc. Titan/cPCI Rear I/O Opto Electrical Interface Selection The Titan/cPCI Rear I/O Opto adapter provides jumper selectable RS-232 and RS-422/485 electrical interfaces on each port. Jumper blocks JA, JB, JC, JD set the electrical interfaces for the individual ports.
Titan/cPCI User’s Manual, Connect Tech Inc. Full Duplex Mode (4 wire) Ensure J1 and J2 for the specific port is removed. You must also ensure that the configuration software does NOT have the ½ duplex or multi-drop slave mode enabled. Half Duplex RS-422/485 (2 wire) Ensure J1 for the specific port is removed, and that J2 for the specific port is installed. Use the configuration software to enable the ½ duplex mode. Multi-drop Slave Mode (4 wire) Ensure J1 and J2 for the specific port is removed.
