PACS bits

Unused bits
Assuming credential PACS bits are 10000000100000000001001111, the keyboard wedge
output follows.
FACCODE section in BIN Output 1000
FACCODE section in DEC Output 8 (left-padding of 0’s for full-byte conversion)
CARDNR section in BIN Output 0010000000
CARDNR section in DEC Output 128
2.3 Card Data Manipulation Options
2.3.1 PACS Leading Byte (firmware 03000000 or higher)
HID credential physical access information is not necessarily byte-organized (for example,
HID 26 bit PACS formats). Output modes like ASCII, BCD, DEC and HEX do require full-
bytes for data conversion from binary input.
This option sets the mode how non full-byte PACS data is converted to full byte stream before
format conversion is performed:
• If un-selected (=default), leading zeros are added to any non-full-byte bit stream.
• If selected, trailing zeros are added to any non-full-byte bit stream. Furthermore, a
leading PACS byte is added, indicating the number of bits the output is shifted right.
Example: Data on card (HID iCLASS H10302 format, 26 bits PACS bits)
0000 0101 0000 0010 0101 0010 01
Representation of PACS bits by 5x27 CK BIN output
In BIN mode the 5x27 CK performs no modifications to the PACS bits. The keyboard
wedge output will therefore be:
00000101000000100101001001
Representation of PACS bits by 5x27 CK HEX, DEC, ASCII and BCD output with PACS
Leading Byte not selected:
In HEX, ASCII, DEC and BCD mode the PACS bit stream will be modified to full bytes.
The data is shifted right by the number of unused bits.
For the example the 5x27 CK builds the following bit stream:
This modified bit stream is converted according to the selected output:
HEX
00140949
ASCII …I
DEC 1313097
BCD 0001 0011 0001 0011 0000 1001 0111
