About UltimaSerial sample programs

Some of the VB6 Sample Programs

UltimaSerial

For other VB varieties, including Visual Basic 2008, please visit our classroom. More samples can be found there

Along with the installation of UltimaSerial ActiveX control, the following VB sample programs are placed under the C:\UltimaSerial\VB directory (Delphi, LabView, VC, TestPoint and Excel programs are covered in other pages).

Sample AnalogInput: reads from analog channel 1 and converts it into voltage for display (a +/- 10V device is assumed in the conversion). The reading speed is paced by a Timer Click here for a screen shot!

Properties/methods/events:

UltimaSerial.Device, UltimaSerial.CommPort, UltimaSerial.ChannelCount, UltimaSerial.SampleRate, UltimaSerial.Start, UltimaSerial.Stop, and UltimaSerial.AnalogInput

Sample Temperature: reads the thermister connected to analog channel 1 of DI-151RS and converts it into temperature for display. If you need more accurate reading, please refer to DI-151RS User's Manual for more info. The reading speed is paced by a Timer Click here for a screen shot!

Properties/methods/events:

UltimaSerial.Device, UltimaSerial.CommPort, UltimaSerial.ChannelCount, UltimaSerial.SampleRate, UltimaSerial.Start, UltimaSerial.Stop, and UltimaSerial.AnalogInput

Sample LimitLine: sets the LimitLine at when analog channel 1 below 0V. LimitLine event will be fired when the input signal on analog channel 1 goes below 0V. Click here for a screen shot!
