Description of the configuration parameters
2.2.2.
“TimeToPowerOff”
Characteristics:
available from firmware:
v1.30.00
Data type:
Word (16-bit)
Unit:
Seconds
Value range:
0-65535
Description:
This parameter sets the duration for how long the transmission carrier remains switched on after the completion of
an inventory, or a tag operation in general.
A certain time must elapse after receipt of an inventory command before the reader can start the inventory. This
time is required by the reader amongst other things for LBT (Listen before Talk) and for an antenna test. Using this
parameter it is now possible to reduce this time: If an inventory has been completed by the reader, and the next
inventory command is received within the time configured by this parameter, the reader can dispense with the LBT and
the antenna test and start the inventory more quickly.
Note
The time during which the transmission carrier is switched on by not performing any tag operation represents an
increase in the overall power consumption of the reader.
The LBT (Listen Before Talk) operating mode is permissible only in existing systems.
2.2.3.
“ModulationType”
Characteristics:
available from firmware:
v1.30.00
Data type:
Byte (8-bit)
Unit:
-
Value range:
0; 1
Description:
This parameter is used by the reader to specify the modulation type used for tag communication.
There are two modulation types available:
0:
Double Side Band (DSB)
1:
Phase Reversal Amplitude Shift Keying (PR-ASK)
Note
For readers manufactured for the European Union (ETSI), Phase Reversal Amplitude Shift Keying is used
irrespective of the setting of this parameter.
