Description
4.2.4 G2CQRY: Gen2 Continuous Tag Query – Single RF Channel
G2CQRY {Q} {sel} {session} {target} {M}
Perform a continuous tag query over a single RF channel
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.
3. No response is returned if a tag query fails.
This mode performs a continuous tag query function on a single RF channel. 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 current RF channel is either the last retained RF channel from one of the two RF channel
scanning query modes or manually set through the RFCHAN command. The current RF channel
may be read through the following direct debug command:
The returned value will be a value between 1 (0x01) and 50 (0x32).
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. When the continuous query mode is terminated, the RF will remain enabled.
