![]() Better yet: connect unused lines directly to ground. The resistor’s value may range from 2.2 kiloohm to 5 kiloohm.Ĭedrus highly recommends that all lines on Port A are pulled low even if you will not be using all 8 input lines. The same diagram applies for lines A1 to A7. The diagram below illustrates how this is done for line A0 (pin 37). ![]() Sometimes, the channel types are changed from thermocouple back to voltage. After setting the proper configuration for the channels, the channel settings are being changed/reset back to Type J. For input, lines must be “pulled low”, that is, connected to ground by a resistor. In InstaCal, I am configuring Channels 12-15 for Type K thermocouples. SuperLab uses Port A for input and Port B for output. These are divided into 3 groups called “ports” and named Port A, Port B, and Port C. The PCI-DIO24 I/O card provides 24 digital input and output lines. Connecting Your Equipment to the I/O Card If you cannot get InstaCal to “see” your board, please refer to the Measurement Computing documentation or their website for assistance. ![]() Īt this point, InstaCal should show “Bd# 0 - PCI-DIO24 (pci slot …)”. From this dialog, select your board model, e.g.From the Install menu, select Add Board.This board must be removed before you add the new one. Right-click with the mouse on “DEMO-BOARD”.If InstaCal shows board number 0 to be a “DEMO-BOARD”, then: In most situations, this happens by default. Once installed, you need to run InstaCal to verify that your I/O card is installed correctly and working. Refer to your I/O card’s manual for information regarding the software installation. Your I/O card comes with a CD-ROM supplied by Measurement Computing. Please refer to your I/O card’s manual for information regarding this first step. Beware not to zap the board with static electricity! Generally, you need to open your PC and insert the card into a PCI slot. The physical installation of the card is not covered in this tech note. Installing the software provided by Measurement Computing.Installing and using a Measurement Computing I/O card consists of the following steps: Note: SuperLab 6.2 for Windows is the last version to support Measurement Computing I/O devices
