Set Application Commands
Command Set 157
Set Current Tag Protocol (93h)
To select a protocol, send the Set Current Tag Protocol code to the reader. A table of
valid protocol codes is found in
Get Current Tag Protocol (63h) . The following example sets
the protocol to GEN2:
Only protocols that are enabled in the reader are available. These protocols are listed in
the version information for the application, described in
Get Boot Loader/Firmware Version
(03h) .
Note
Changing protocol parameters manually using Set Protocol Configuration (9Bh)
will maintain their value across changes in the current protocol using Set
Current Tag Protocol (93h) . Their values will NOT be reset if the protocol is
reset, only if the module is power cycled or the application firmware is
reloaded by a
Start Bootloader (09h) followed by a Boot Firmware (04h) .
Note
Calling Set Current Tag Protocol will reset the Tag Buffer.
Set Write TX Power (94h)
The Set Write TX Power command sets the default, module-wide, power level to use for
writing to tags. This is necessary because a write operation may require a different RF
power setting than a read command. The format and arguments of this command are
identical to the Set Read TX Power command:
Note
Power settings for individual logical antenna ports specified in Set Antenna’s
Power and Settling Time override the value set here.
