Description
4.2.2 G2FASTSCAN: Gen2 Continuous Tag Query – Fast RF Channel Polling
G2FASTSCAN
Perform a continuous tag query over all RF channels
None
NOTES:
1. The actual number of EPC words returned is defined in the Protocol Control word. The number of
words can be any value between 0 and 6. The shown configuration (number of words = 6) is typical.
Refer to the G2WRITEEPC command (section 4.4.3) for detail on the defined number of EPC data
words.
2. The PC and CRC words are delimited from the EPC identifier with underscore characters on the
computer’s terminal.
3. No response is returned if a tag query fails.
This mode performs a continuous tag query function over all 50 RF channels in a similar manner as
the G2SCAN command, however failing channels are quickly skipped over. For each RF channel, a
single tag query is performed after which the RF channel is incremented (RF channel 50 rolls over to
channel 1). When a tag is successfully queried, the EPC identifier is displayed on the terminal and
the buzzer will output a short high-pitched chirp (if enabled).
The continuous query scanning mode is terminated by either pressing the escape <ESC> key, space
bar, or ENTER key a single time. This mode must be terminated prior to executing other Gen2
commands. Depending on the state of the reader when the escape key is hit, the RF may be on or off.
In the event that the RF is off and additional tag access commands are required, the following must be
performed:

4. The reader will require the RF be re-enabled: CLI command = RFON.
5. Perform a single query on the tag: CLI command = G2QRY.
6. Perform any additional access commands.
