FIFO trigger

This command is used to communicate with an RF tag and output the result when ID command execution request is turned on

with the RF tag stopped within the antenna communication area.

After communicating, the RF tag is prohibited to move.

When using this command, set 0003H to Communication specification area (Un\G1, Un\G4001).

RF tag C

RF tag B

Operable

• When ID command execution request (Y14, Y1C) is turned on, ID-BUSY (X3, XB) turns on and the module starts to

communicate with an available RF tag.

• After communication with the RF tag, the RF tag is prohibited to move and ID command complete (X4, XC) turns on.

• When ID command execution request (Y14, Y1C) is turned off, ID-BUSY (X3, XB) and ID command complete (X4, XC) turn

off and the module changes to a standby state.

• If no available RF tags are within the antenna communication area when ID command execution request (Y14, Y1C) is

turned on, the status flag (bit 10) of Error details storage area (Un\G41, Un\G4041) and Error detection (X5, XD) turn on.

• The module does not communicate with the RF tag (prohibited to move) that have already communicated with in the

communication area. When the RF tag prohibited to move moves outside the communication area, the moving prohibition

of RF tag is cleared.

• Set only one available RF tag in the antenna communication area. When multiple available RF tags are within the antenna

communication area, communication is not performed normally and Error detection (X5, XD) turns on.

• This function cannot be used to communicate with V680-D1KP.
