Devices Attached combo-box lists all the mmb16
devices detected attached to this computer, and
aren’t in use by other software. The detection is
done when the Chart document is loaded or
created. Choosing a device in this list lets you see
and configure it, one device at a time.
The current device’s settings can be duplicated
onto one or more other units, using either the
Copy… button or the Load/Save functionality.
The new settings are only applied to the attached
devices when the “OK” button is pressed.
The Device Name field lets you name that specific
mmb16 unit. For example, if you are using one
mmb16 per cage, then you may like to name the
unit after the cage it is attached to.
The Beep checkbox chooses whether or not the
mmb16 will emit a short beep whenever an input
event is detected.
Each of the 16 inputs, can be individually configured as follows:
Name is what the input is called. This text is used in the comment added when the input has an event
detected on it, and may be something like “Lights ON” or “STIM ON”.
High/Open and Low/Closed let you give meaningful names to the two possible states of the input line. For
example, with lights it may be “Off” and “On”. Along with the device and input names, this is also used in
the comment added to chart.
R and F checkboxes select whether you want to detect rising and/or falling edges on the input. For example,
for a food dispenser, you may only want to detect the rising edge as “pressed food button”.
Time Threshold is the minimum amount of time that the input must be in a new state before it is considered
valid. Even though this delays the detection of the event, the actual position that the event is reported is the
initial edge. This parameter lets you do two things:
•Detect a pulse of a minimum length, e.g. a lever is pressed for a minimum required time. Set the
time threshold to the minimum time the pulse must be present for. This will also filter out any short
releases followed by a press again.
•Remove noise, and debounce inputs. Set the time threshold to a smaller value. If the input signal
isn’t conditioned, then this will remove any
contact noise from switches, etc.
Comment Channel chooses which channel in Chart will
get the comment when the event is detected.
A sample configuration is shown:
Along the bottom of the dialog are four buttons that
provide extra functions.
Defaults... reverts this device’s input settings back to factory defaults. Note that
this excludes the Device Name and Beep settings. After pressing the button,
select the items to reset, then click OK.
The default settings are not sent to the device until “OK” is pressed in the main
dialog, so ”Cancel” can still be used.
