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

of the

on the Connect Tech website for product manuals,

installation guides, diagnostic utilities and device driver software.
