Variable Card Page
The Variable Card Page allows you to configure the system to accept card formats other than the
pre-defined standard formats normally supported. This provides wider flexibility in the use of existing
cards.
Custom Card Formats are used when upgrading readers without having to change the existing card
technology at a site. By entering the bit location and length in each of the code fields, a card format is
created that is then assigned to one or more readers. You can define up to 15 Wiegand and 15 Mag
Stripe Card custom formats.
To navigate to the Variable Card page, from any Setup page click the Variable Crd tab button at the
top of the window, or from the main Setup page click the Variable Card Format button on the right
side of the page. The following page displays.
The Variable Card page contains the following information:
Wiegand Card Format # 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. See
Wiegand Card Formats are defined in terms of bits (a bit is either zero or one)
Card Length
Select from 1 to 63 bits for the Card Length. Most Topaz installations use a 37-bit format. Another
popular Wiegand Card Format is a 26-bit format.
No Parity
The default is to use parity. You may turn parity off by selecting No Parity, to place a check mark
in the box.
Company Code
• Start - Select the location of the first bit for the Company Code as the Start value. For the
normal Topaz installation, the Start value is 2, meaning the Company Code starts in the
second bit in the string of bits. For a Start value, select from 1-64 bits.
• Length - The Length is the number of bits to use for the Company Code. For a length, select
a value from 0-16 bits.
