WSE Technologies DR4201 - Reader Operation (26-Bit and 34-Bit Wiegand Mode)

DigiReader Series
12 P/N 6600025, REV. D
• Key type 2 (HID ProxPro™, ISOProx™, DuoProx™, and Corporate 1000™):
For 120 msec the key message data is serially shifted into a buffer while searching for a
48-bit FSK-modulated Manchester-encoded signal. The received key data is valid if it
contains:
• a start character with 2 Manchester code violations,
• no other Manchester coding violations, and
• the receive buffer contains two identical 48-bit key messages.
Reporting as an SNET DKR-type, only the key ID is reported to the ACU.
Reporting as an SNET MSR-type, this key is reported to the ACU in an SNET MSR-type
log response. The MSR data sent depends on the key type recognized:
• 26-bit key:
• key data in message characters 7-10,
• site code in message characters 11-14,
• company code (always 9999) in message characters 19-22.
• 35-bit key:
• key data in message characters 6-10,
• site code in message characters 11-14,
• company code (always 9999) in message characters 19-22.
• 37-bit key:
• key data in message characters 6-10,
• site code in message characters 11-14,
• company code (always 9999) in message characters 19-22.
• Only one keycode is received and reported at a time. A 1-second timer is started
when a key is read to prevent the same key from being repeated too quickly.
READER OPERATION (26-BIT AND 34-BIT WIEGAND MODE)
• The RF field is powered at all times.
• A digital key is received in the same fashion as for the SNET operation. (See above).
• If the key is in 88-bit WSE format, then either the 32-bit (or 26-bit) keycode is immediately
transmitted via the data 0 and data 1 lines, most-significant-bit first.
• If the key is a 48-bit type then the key content is checked to determine if 26-bit, 35-bit or
37-bit data is to be sent. If the content cannot be determined then no message is sent.
• Only one keycode is received and reported at a time. A 1-second timer is started when a
key is read to prevent the same key from being repeated too quickly.
