System variables for the apC Driver

System variables for the apC Driver lists system variables used to define various settings for the apC Drivers.

Note: If an apC Driver variable requires a driver restart for changes to take effect, or if the system variable setting cannot be changed while the apC driver is running, that is documented in its description in the System Variables list.

Table 1. System variables for the apC Driver
System Variable Name	Description	Value Type	Default Value
Maximum Issue Code	Maximum issue code supported by apC panels. If the issue code in a credential record that you import or edit is too large for the current value of this variable, the credential is not downloaded to the apC panels. Changing the value of this variable affects new credential records being downloaded only. The system does not validate existing credential records against the new changed value. The value must be between 0 and 255.	Numeric	7
Maximum Clearances per Person on an apC	Maximum number of clearances for each person that can be downloaded to an apC panel.You cannot change this value if the apC driver is running. You must stop the driver, make the change, and then restart the driver. The value must be between 1 and 80.	Numeric	20
Maximum Number of apC Clearances	Maximum number of clearances that can be downloaded to an apC panel. You can set this value higher than 256, but it might decrease the number of cards that the panel can store. The value must be between 256 and 32767.	Numeric	256
Is Using Activation Dates	The activation date in the credential record is downloaded to the apC panel. If True, the activation date is downloaded to the panel. If False, the activation date is not downloaded to the panel. Setting this variable to True decreases the number of cards that the panel can store. This value cannot be changed if the apC driver is running.	Boolean	True
Is Using Deactivation Dates	The expiration date in the credential record is downloaded to the apC panel. If True, the expiration date is downloaded to the panel. If False, the expiration date is not downloaded to the panel. Setting this variable to True decreases the number of cards that the panel can store. You cannot change this value if the apC driver is running. Note: You must stop the apC driver, change the system variable, and restart the apC driver for changes to take effect.	Boolean	True
Minutes between Sending Date and Time	Amount of time in minutes, that must pass before date and time is re-sent to re-synchronize the server and apC times. The value must be between 1 and 1000. Note: You must stop and restart the apC driver to have any changes you make to this variable take effect.	Numeric	60
Number of apC Simultaneous Personnel Downloads	Number of apC panels that can have personnel downloaded to them at the same time. The value must be between 1 and 50.	Numeric	10
Journal Occurrence Difference Range	For a journal message, if the apC driver-received time and the activity-occurred time differ less than the entered value (in seconds), only apC driver-received time displays in the Monitoring Station and journal view. The value must be between 0 and 60.	Numeric	0
Force Full Personnel Download at Driver Start	Forces full download of credentials to all panels at next driver startup. If True, the credentials are downloaded to the panel. If False, the credentials are not downloaded to the panel.	Boolean	False
