Command Data Type R, W, R/W Definition
rfid:qid
Function Reads current queued ID data
EXAMPLE Output String:
{0x1000,2,0x0000,80;0x000000801DD1910
B2F04}
---Note the use of commas and semicolons--
FORMAT of Output String:
{AGE,OVERRUN,LOCKOUT,BITCOUNT;ID}
AGE (New: Age (in hex) of last card read as a
multiple of 48ms. Value stops at 0xFFFF. Use
qid.id function to clear the age counter. As
shown: the card was read 4,096 (0x1000 hex)
x .048 = 196.608 seconds ago or 3 minutes and
16 seconds.
OVERRUN counter (Values: 0 through 255):
number of times buffer has been over written
with new data without content transfer.
LOCKOUT: Time (in multiples of 48ms) re-
maining until another card can be read.
BIT COUNT bit length of card data (26 to 255).
As shown: The ID contains 80 bits.
ID: Card data in hexadecimal. As shown: Card is
80 bits and is 0x000000801DD1910B2F04.
rfid:qid.hold
Function Read the card data and reset lockout timer.
Once the function is called, a new card can be
read immediately after without waiting for the
lock out time period to expire.
rfid:qid.id
Function Reads the card data, clears the age, overrun, and
bit count after function is called.
rfid:qid.id.hold
Function Combined functions of rfid:qid.hold and
rfid:qid.id
rfid:time.hold
INT R/W Verify or set current data hold time setting in
multiples of 48ms. (0 - 200) Also controls
duration of Green LED during Auto mode.
rfid:var
Function Outputs current command variables in ram
(Similar to a .HWG file.) Output can be cap-
tured, edited and written back into the device.
Note: To prevent an input buffer overflow, delay
each character by several milliseconds.
rfid:wieg.id.bits
INT R/W Verify or set card data output bit count (0- 255)
rfid:wieg.inv.bits
BOOL R/W
IF True, Invert card data output bits
(1 to 0, 0 to 1)
rfid:wieg.qual
BOOL R/W
IF True, use wiegand qualifier to verify card bit
count
