Appendix D: RS-485/422 Line Interface

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 Tip

Please refer to the README files on the driver diskettes for technical tips or release notes concerning installation and configuration of various device drivers and software utilities. If you require further information please contact Connect Tech Technical Support
