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

Due to the resolution of DI-194, you may not use thermister with this device.

If you need to use thermocouple to measure a wider temperature range, please consider DI-195B with 5B-47 Modules

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!
