3. Calibrating the DI-194RS Serial Port Module Your DI-194RS serial port module initially arrives in an uncalibrated state. You must perform this initial “fine tuning” before recording waveforms to disk. Since this procedure requires a voltmeter, have it handy before starting. - Page 14 DI-194RS User’s Manual With channel 1 selected (step 2), click on High Calibration… in the Edit menu. This displays the High Calibra- tion dialog box. The values entered for the Low Calibration will appear here. Enter the value measured in step 7 in the High Cal Value text box and click OK.

Dig 2: Digital port 2. To connect signals to the DI-194RS, insert the stripped end of a signal lead into the desired terminal directly under the screw. Tighten the pressure flap by rotating the screw clockwise with a small screwdriver. Make sure that the pres- sure flap tightens only against the signal wire and not the wire insulation. - Page 16 DI-194RS User’s Manual Loosen Tighten Screwdriver Signal lead Pressure flap When an input signal is connected, W /Lite’s real time display immediately reveals the input waveform on your computer’s monitor.
