[Function]
This command specifies the antenna output power.
The antenna output power for the write command and the antenna output power for the read command can be set to
separate values.
[Format]
<IP5>aaa(,bbb)
●Parameters
aaa = 0 - 240 (When a ThingMagic module is loaded)
bbb = 000 - 240. Antenna output power of the read command. Three-digit number with 10 times the dBm value (can
be omitted)
If you specify only aaa, the antenna output power is set with both the write command and read command
having the same value.
When both aaa and bbb are specified, the antenna output power setting is made by using the value of aaa
for the write command and the value of bbb for the read command.
For details on the actual antenna output power, refer to the antenna output power setting table.
[Coding Example 1]
<A>
<IP5>170
<Z>
The antenna output power is changed to 17.0 dBm without restarting the printer, and this value is
maintained even when the printer is turned OFF.
<A>
<IP5>120,090
<Z>
The antenna output power of the write command is changed to 12.0 dBm, and the antenna output
power of the write command is changed to 9.0 dBm without restarting the printer. These settings are
maintained after turning off the printer.
[Supplemental explanation]
1. This command cannot be used in combination with other than <A> and <Z>.
2. This command is not processed when receiving during printing. Will be processed after printing is completed.
3. Since the antenna output power changes, it may not be possible to read or write some tags depending on their type.
4. If you specify a value outside the range of parameters, a command error occurs.
5. The default factory setting is 100.
6. While the same setting can be performed with the [DC2] PA command, this command can instantaneously change
the radio output power without having to restart the printer.
7. While a value from 0 to 240 can be recorded in the nonvolatile memory of the printer, the units place is rounded off
to 0 during transmission to the reader/writer module.
8. A number that is less than 100 is set to three digits by supplementing with a zero in the high order digit.
