Digital I/O Window
Asynchronous Digital I/O Window – P2 Digital I/O
This window is displayed when the Digital I/O button on the main window is selected. It provides
interactive control of all configured digital I/O ports (as configured in the Configure System Hardware
window). The base unit has the three 8-bit ports of P2 that can be configured as either inputs or outputs.
Up to twenty 8-bit ports can be accessed when expansion boards are added. When the Execute button is
pressed, all ports configured as outputs will be updated and all input ports will be read.
Counter/Timer Window
Two C/T modes are available for the DaqTemp devices.
• Totalize Input – Counts rising or
falling edges of signals from the
related pin on P3 adapter. Each
channel has its own Reset button.
• Square Wave Generator Output
– Outputs a square wave on each of
2 channels with a selectable
frequency and duty cycle.
Note: Channels that are enabled in the scan cannot be used from the asynchronous counter/timer
window.
