S2.1 – S2.6 – Reader Format DIP Switches
DIP switches S2.1 to S2.6 set the control board for the reader format in use. Table 4 lists supported reader
formats, corresponding DIP switch settings, and the security levels of the card/reader formats.
26-bit cards and tags are not secure. Duplicate card numbers
exist in this format so a facility is vulnerable to unauthorized
access.
KEYSCAN systems are factory defaulted to use KEYSCAN’s proprietary
36-bit Wiegand format cards and tags. KEYSCAN’s 36-bit proprietary
Wiegand format ensures no duplicate cards or tags exist offering a high
level of security.
KEYSCAN assumes no responsibility for liability for any card
format.
26-bit Waiver of Liability
Installing dealers should have an authorized end-user sign a waiver of liability before enabling 26-bit cards.
Keyscan has enclosed a Waiver of Liability at the back of this guide on page 110.
Advantage of Keyscan 36-bit Proprietary Wiegand Format
Keyscan’s 36-bit proprietary Wiegand format cards and tags, which include a manufacturer’s code, offer a high
level of security. Keyscan tracks all its cards and tags. This ensures that no duplicate cards or tags are sold by
Keyscan. When installing or upgrading a Keyscan access control system, we recommend our proprietary
Keyscan 36-bit Wiegand format cards and tags, available in 125 kHz or 13.56 MHz formats, for a high level of
security.
Security Levels
The table on page 42 reviews not only the supported reader formats, but also the security level of each
format. Be aware that where Keyscan’s 36-bit proprietary cards share a combined reader format with other
manufacturer’s cards, the other manufacturer’s card binary bits may be truncated to accommodate the joint
format. This lessens the overall security, as not all bits are read.
Reader formats in Table 4 have been given one of following security ratings:
High
Medium
Low
Very Low
Reader formats ranked with medium, low, and very low are NOT recommended. The ratings are based on
whether a card’s binary bits are truncated and/or the cards are sold by other manufacturers, which Keyscan
has no control over.
Card Number Formats
The supported card number formats fall under the following two types:
Standard Card Number – 3 digit facility code* / 5 digit card number
