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.
