Configuring a RS-232/RS-485 SCXI System

Primary Software: Driver Software>>NI-DAQ
Primary Software Version: 6.9.3
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: SCXI

Problem: What steps should I take to setup up and run my remote SCXI system?

Solution:

The aim of this troubleshooting guide is to take you through the procedure of setting up and using a remote SCXI system. We will run through the necessary hardware connections and the steps required to configure the system using the Measurement and Automation Explorer (MAX).

A remote SCXI system can be controlled using either an RS-232 or RS-485 link, the choice of which will depend on the distance between the chassis and the host PC. For systems where the chassis is to be more than 33m (100ft) away from the host PC, an RS-485 connection should be made. Any configuration differences between the RS-232 and RS-485 systems will be identified where appropriate.

Prerequisites

One of the following two options:

  • SCXI-2000 4 slot chassis with built in RS-232/485 communication
  • SCXI-2400 module and an SCXI-1000/1001 4 or 12 slot chassis

 

The following required elements:

  • SCXI-1200 Multifunction DAQ module
  • NI-DAQ 4.9.0 or later
  • Transducers or voltage source(s) for system testing
  • A PC with a spare serial (RS-232) port or a plug-in RS-485 card e.g. AT-485

 

Note: While an SCXI-1200 is almost always included, it is possible to use an SCXI-1124 or SCXI-116x in a remote situation without an SCXI-1200 module.

Optional elements:

  • One or more SCXI modules

Throughout this guide we will consider the configuration of the following example setup:

  • SCXI-2000 communicating via RS-232
  • SCXI-1200
  • SCXI-1100 32-Channel Multiplexer/Amplifier module
  • SCXI-1163 32-Channel Optically Isolated Digital Output module

 

There are three steps to perform in setting up your remote SCXI system:

  1. Hardware configuration
  2. Software configuration
  3. System testing

Once you are familiar with the steps necessary to use your remote SCXI system, feel free to visit our SCXI & Signal Conditioning Support page for additional documentation.
