Digital Outputs

This dialog, accessed through the System - Digital Outputs… command or by icon, is used to control the digital outputs of the installed A/D boards. These TTL outputs can control, via the Event Table (for more details see also chapter Event Table), the external measuring devices during the analysis. The command enables one to set up the initial and current state of these outputs by means of the displayed Digital Output Control dialog. Any changes performed in the dialog will be saved at the moment of the dialog closing.

Note:

If more than one board has been installed, the Select Control dialog containing a list of all boards will open first. If a converter has not been installed or is not functional, the Digital Outputs… command will not be active (dimmed).

Digital Output Control

Output no.

Lists the numbers of individual outputs.

Initial State

Selects the Initial status of the digital output when the station starts. The status is indicated in two halves: first shows the digital output (Output) and second its usability as a relay (Relay). Where no relay contact can be used, only the state of the output is shown.

Current State

Displays and enables modification of the current status of outputs. The status is indicated in two halves: first shows the digital output (Output) and second its usability as a relay (Relay). Where no relay contact can be used, only the state of the output is shown.

Change in these columns takes effect immediately. To change the status click the corresponding field with the inscription HIGH or LOW indicating the output value. The output status is also indicated by color, where gray corresponds to logical zero (LOW) and green to logical one (HIGH).

Descriptions

Outline description indicating the meaning of individual outputs. The names of individual digital outputs can be edited in the System Configuration dialog for the actual device providing the outputs.

Note:

It is not possible to access the Digital Outputs dialog of the device that is configured solely on the Instrument you do not have the access to. The access to particular Instruments for different users may be set in the User Accounts dialog.

Note:

Access to the Digital Outputs dialog can be controlled through the User Accounts dialog by checking or unchecking of Open Configuration item in the User Access Rights section.
