Tektronix DAS-Scan Quick Start Guide

DAS-Scan Quick Start

The DAS-Scan system is a data acquisition system that allows you to measure voltage and/or thermocouple input on up to 4,096 analog input channels. You can use your DAS-Scan data acquisition system with the following software:

● ASO-SCAN software (Advanced Software Option) - Install this

software if you want to create data acquisition application programs at the driver level using Microsoft Visual C++, Borland C/C++ (for Windows), or Microsoft Visual Basic for Windows.

● VTX (Visual Test Extensions) - Install this software if you want

to create data acquisition application programs using an integrated set of custom controls within the Microsoft Visual Basic Windows programming environment.

● TestPoint - Install this software if you want to create data

acquisition applications under Windows using a set of professional software tools instead of programming.

To begin, use the DAS-Scan system setup checklist to set up your DAS-Scan system. Then, follow the quick start instructions for the software package you want to use.

DAS-Scan System Setup Checklist

Use the following DAS-Scan system setup checklist to set up your DAS-Scan system. Refer to the DAS-Scan User’s Guide for detailed instructions.

❏ 1. Unpack and inspect the components of your DAS-Scan system. ❏ 2. Create a channel map indicating the input signals you want to attach

to each of the channels in your DAS-Scan system.

Part #94830; Revision A; July 1996 1

❏ 3. Conﬁgure the hardware components, as follows:

– On the SCAN-AD-HR board, set the base I/O address switch

(S1) to indicate the appropriate base I/O address, and, if appropriate, set the J6 jumper to indicate an external pacer clock or an external digital trigger/hardware gate.

– On each SCAN-BRD assembly, set the address thumbwheels to

indicate the appropriate assembly address. (For the purposes of this quick start, make sure that you set the address of the ﬁrst assembly to 00h.)

– If you are using SCAN-STP-TC screw terminal panels, set the J2

jumpers on each panel to indicate whether you are using cold junction compensation (CJC).

❏ 4. Mount the SCAN-STP screw terminal panels on DIN rails. ❏ 5. Attach the input signals to the appropriate SCAN-STP screw terminal

panels.

❏ 6. Mount the SCAN-CH chassis in a 19-inch rack. ❏ 7. Attach one end of each SCAN-CAB-64 cable to the appropriate

position in the SCAN-CH chassis. (Do not attach the other end of the SCAN-CAB-64 cables at this point.)

❏ 8. Attach a power cord to the power-supply panel of each SCAN-CH

chassis.

❏ 9. Check the operation of the power supply in each SCAN-CH chassis. ❏ 10. Install the SCAN-BRD assemblies in the appropriate SCAN-CH

chassis.

❏ 11. Make sure that power to the computer is turned OFF. ❏ 12. Install the SCAN-AD-HR board in your computer. ❏ 13. Attach the SCAN-AD-HR board to the ﬁrst SCAN-CH chassis using

the S-1802/M cable.

❏ 14. Daisy-chain multiple SCAN-CH chassis, if required, using

S-1802/MM cables.

❏ 15. Attach the other end of each SCAN-CAB-64 cable to the appropriate

SCAN-STP screw terminal panel.

❏ 16. Connect an external pacer clock, external digital trigger, or hardware

gate, if required, to the J5 connector on the SCAN-AD-HR board using a CAB-SMA-BNC cable.
