The Discrete Output dialog consists of three configurable parameters: Name, Type and
Details.
A.1.1 Line Name
A new Name for an output Line may be assigned by selecting the field containing the default
name, and entering the new name using the text entry dialog. The name may be up to 15
characters. The Line Name is used for reference purposes only; it does not change the func-
tionality of the output line and cannot be referenced in the spreadsheet.
A.1.2 Line Type
One of sixteen available Line Types is selected from the drop-down menu list. The available
types are described in Table A-2.

TYPE
DESCRIPTION
Programmed
Enables a WriteDiscrete function in the spreadsheet to control the state of this
output line. Either pulsed or steady-state.
High
Forces the output to HIGH (1).
Low
Forces the output to LOW (0).
Acquisition Start
Pass through of the acquisition trigger signal. Always pulsed.
Acquisition End
Signals the completion of camera acquisition. Always pulsed.
Job Completed
Signals each time the spreadsheet has completed an update. Always pulsed.
System Busy
HIGH when the In-Sight sensor is running a job or responding to user input,
LOW when the In-Sight sensor is idle.
Job Load OK
Signals the successful loading of a job. Always pulsed.
Job Load Fail
Signals the unsuccessful loading of a job. Always pulsed.
ERR: Missed Acquisition
ON means that an acquisition trigger was received before a previous acquisition
could be completed. The output line State is automatically cleared whenever the
Discrete Output dialog is opened or closed. Always pulsed.
ERR: Tracking Overrun
ON means that the spreadsheet issued a delayed discrete output signal some-
time after it was expected. The output line State is automatically cleared when-
ever the Discrete Output dialog is opened or closed. Always pulsed.
ERR: Tracking Queue Full
ON means that the spreadsheet issued a delayed discrete output for a line
where a different output had been previously scheduled to occur at the same
time. The output line State is automatically cleared when the Discrete Output
Dialog is opened or closed. Always pulsed.
Online/Offline
HIGH when In-Sight is Online, LOW when In-Sight is Offline.
Strobe
1
HIGH when the In-Sight sensor is exposing the CCD. Always pulsed for the
duration of the exposure. The leading edge of the signal can be used to trigger a
strobe. The exposure time must be 0.50 ms greater than the strobe pulse dura-
tion specified on the external strobe device. This output type is only valid for
High Speed Output Line 1 (HS OUT 1). The In-Sight sensor and strobe device
must be connected to the same ground for the strobe to operate correctly.
