Write position control parameters (can be omitted)
tof: Temporary tag offset setting
Module control parameters
(can be omitted)
pow: Temporary radio output power
When this parameter is specified, the tag offset is changed
temporarily from other than the settings made from the RFID
user mode menu and the [DC2]PA command.
The valid period of the specified value is only once of all the
times the <IP0> command is issued.
The write stop position of items for which this parameter is not
specified conforms to the tag offset set in the printer.
The setting range is from 0 to 240 mm.
When this parameter is specified, the radio output power is
changed temporarily from other than the settings made from
the RFID user mode menu and the [DC2]PA command.
The value that can be specified is 10 times of the dBm value,
and is in the range of 0 to 240 (0.0 dBm to 24.0 dBm).
However, the units place is rounded off during transmission to
the module.
The valid period of the specified value is only once of all the
times the command is issued.
When this parameter is not specified, the write radio output
power conforms to the radio output power value set in the
printer.
This parameter cannot be used when the EPC/TID return
function is enabled by using EPC/TID return <RU>.
For details on the setup value, refer to the antenna output
table of antenna output <IP5>.
