2.9.1 Advanced DIO Options
When testing DIO functionality, it is sometimes required to view the current state or change the
state of a DIO. For example, when connecting an auto sampler it is recommended to manually
pulse the signal to make sure all of the wiring is correct, and the sampler will activate when a
control output condition occurs. To do this in iChart go to the Advanced | iSIC | iSIC menu.
The iSIC Setup dialog box will open:
The first screen gives you the iSIC connection opens. Enter the COM port and connection method
of the desired iSIC as well as the iSIC Address. For example, if you are trying to connect to a
2100-iSIC with a modem connected to COM3, select 2100-iSIC from the connection drop down
menu, and COM3 from the COM port menu. The iSIC Address will typically be “1” unless
changed by the user. When this information has been correctly entered, click Connect.
After connecting click on the IO tab the current DIO and tip status will be displayed. If the DIO
pin is configured as an input in the Project Setup Device Wizard, it will be grayed out and show
the current status. If the DIO pin is configured as an output, it will allow you to change the
status by selecting a new value and placing a check in the Change check box.
Note: DIO manual status changes will automatically change back to the DIO normal operating
condition at the next sample interval, or the top of every hour, whichever comes first.
