7.4 Packet
In case of
UNIDIRECTIONAL
communication, the active tag continues to transmit its message as long as it remains in the detection zone.
This happens every 500 mS if there is a single aerial or every 1 Sec., 1,5 Sec or 2 Sec. if the aerial is synchronized with others.
After any transmission of the active tag, the receiver sends on the Wiegand bus a train of bits or activates the relays.
NOTE: the communication Unidirectional or Bidirectional concerns all the tags and not each tag individually
It is possible to set the repetition period of the wiegand signal or the repetition period of the relay activation.
Select this period on the submenu PERION of the option “NO Ack”.
Setting ( for example ) 10 Sec. as long as the tag
remains in the activation zone
the wiegand signal
leaves every 10 Sec or the relay activates every
10 Sec.
No ACK =
UNIDIRECTIONAL
communication between Active-
TAG and RX
ACK =
BIDIRECTIONAL
communication between Active-
TAG and RX = after any transmission of
the tag at 433 Mhz, the receiver replies with a confirm signal that stop the further transmissions of
the tag, even if standing inside the detection zone and woken by the trigger
aerial.
7.4.1 ACK
7.4.1 NO ACK
As soon as the user, carrying the active tag, enters the detection zone of 125 KHz, its tag emits a 433
MHz RF signal to the receiver which replies with a confirmation message that hushes the tag, even if
it remains in the field.
To restart the transmission the tag must be carried outside the field unless for 6 sec.
System ACK
PRO
CONS
Less battery consumption of the tag
Need to exit from the field to restart
the transmission
Extended stationing of the tag inside
the field
System NO ACK
PRO
CONS
System more reactive
More battery consumption of the tag
No need to exit from the field
The active tag owned by the user, standing inside the field, continues the transmission each time is
woken by the antenna .
The re-transmission period is set by the parameter “PERIOD”

7.3 Output
Sets the receiver output : WIEGAND or RELAY.
If you choose the WIEGAND mode, the receiver, once
received a valid signal from the tag, sends out its
serial number and the ID of the antenna trigger on the
wiegand bus. See menu CONFIG for the settings of
the wiegand protocol.
If you select RELAY mode, the receiver activates
the relay1 or relay 2 according the corresponding
settings. See menu CONFIG for the options of the
relays.
