Outputs States
States Output states are used in the construction of sequences. There are six categories of output
states:
1 General: The general category includes Start Recording, Stop Recording and
Update.
2Dig. Output: Controls the digital outputs. For each digital output there is an on
state and an off state. You can also turn all digital outputs on or off simulta-
neously.
3Stim#: Controls the corresponding stimulator parameters. This can be used to
change the stimulator parameters on the fly.
4Mark: Set Marks in the record.
5Message: Display User Messages on the screen.
6Sound: Plays an existing audio file, located in the same folder as the current
settings file.
The WPI 118 has up to eight Digital Outputs in two banks. BNC’s 5 -8 can be configured as
Digital Inputs or as Digital Outputs. Each digital output can be controlled independently.For
each digital output there are two states, On and Off. So for eight digital outputs we have 16
states.
Naming States Each output state can be named. To name an output state, click once to select the state, then
click again to edit the name. Type the new name of the state in the Edit box that appears. If you
want a mark to be placed on the record when the digital state is fired, double-click the checkbox,
next to the label, so that a checkmark appears. For example, in the figure below, DO2 On has
been labeled as Pump On and set to place a mark in the record when it is fired.
