How to add a card format

Wiegand Card Formats

Cards with the Wiegand Card Format are usually ordered pre-coded with information (company
code, facility code, and card number). Most Topaz installations do not require a format change. If you
do wish to change the format you are using, you can do so with this screen.

Wiegand Card Formats are defined in terms of bits (a bit is either zero or one).

To add a Wiegand Card Format:

1. Select from the drop-down list of Wiegand Card Format #s. Once a record is selected, the

screen displays the remaining fields for this format.

2. Select the Card Length.

3. If desired, you may turn parity off by selecting No Parity.

4. Select the Start value and Length for the Company Code, Facility Code, and the Card

Number.

5. Click Save.

Issue Code

The Issue Code is normally 1 digit and is set to 1. You can use an Issue Code for replaced cards,
etc.

• Start - Select the location of the first bit for the Issue Code as the Start value. For a Start

value, select from 2-40 bits.

• Length - The Length is the number of digits to use for the Issue Code. For a length, select a

value from 0-2 digits.

• Field Separator - Most cards do not use a Field Separator. It is most commonly used when

compatibility is required with Time and Attendance programs and other systems. When you
select a Field Separator, Topaz uses the letter D. If you want to use a Field Separator, click
the box to the right of the field. Topaz ignores the Field Separator digit in counting where
data fields start.

Save

Once all changes have been made to the Variable Card page, click Save.
After clicking Save, the “Operation Complete” messages displays.

Clear

At any point if you wish to clear out all entered information and start over, click Clear.
