2.4.2. Wiegand Data Port (PSR-W26-1 model only)
Wiegand data format allows ParSec Readers to be connected directly to access control
systems using this standard. This 26-bit version uses the industry standard format as follows.
Bit 1 Even parity on bits 1-13
Bits 2 - 9 Site Code as printed on tags
Bits 10 - 25 Tag no as printed on tags
Bit 26 Odd parity on bits 14-26
Connections for use with an InterPoint are shown below.
ParSec Reader InterPoint Function
TB1 TB4
1 1(12V) 12V
2 3 (0V) 0V
8 4 (R1) D0
9 6 (R3) D1
13 7 (RED) Red LED
11 8 (GRN) Green LED
Set the InterPoint reader mode DIL switch 5 to 8 all off i.e. as for a Wiegand card.
2.5. External Sensor Operation
With radio tags, it is often difficult to ensure that personnel type tags which transmit every
0.6s are only read in specific areas e.g. only near a door. By using an external sensor such as
an infra-red beam or a passive infra-red detector and connecting this into the reader, PS-
PET1-1s will be ignored unless the sensor is activated. See section 4.4.4 for more details.
Note current production readers do not support this function. A field upgrade kit will be
made available in 1999.
