DATAQSERIAL Active X Control

Description:

If you are using an older DI-194 with only one channel enabled, you need to purchase a “key” (a hex number) from DATAQ instruments if you want to enable more than one channel. To purchase the Key, you need to get the serial number from the device first.

Syntax:

DataqSerial1.Key=variable (where variable is the hex number purchased from DATAQ)

Variable:

String

Example:

Private Sub Start_Click()

DataqSerial1. Device = 194

DataqSerial1.Key = '(hex number purchased from DATAQ)

'you can now enable 4 channels

DataqSerial1. ChannelCount = 4

DataqSerial1. EventLevel = 20

DataqSerial1. Start

End Sub

Private Sub Stop_Click()

DataqSerial1. Stop

End Sub

Private Sub DataqSerial1_ NewData (ByVal Count As Integer)

DQChart1. Chart (DataqSerial1. GetData)

End Sub
