GEN2 SELECT

The following steps outline the process through which data may be read or written to a specific tag (known by its EPC).

1. Specify the length of the known EPC by entering ‘SELECTDATALEN [LENGTH]’, where [LENGTH] is measured in bytes.
2. Specify the EPC of the target tag by entering ‘SELECTDATA [EPC]’ (Example: SELECTDATA E2003412DC03011951069430).
3. Specify the offset; from what byte of the EPC onward should be used as the filter. Entering ‘SELECTDATALEN 4’, for example, will use the EPC previously stored in SELECTDATA and use the 4th byte onward as the filter to select a specific tag.
4. Now that the parameters describing a specified EPC have been set, the actual data to be read/written is specified. The memory bank of the target tag (already specified by its EPC in the previous steps) is selected by entering ‘MEMBANK EPC’, ‘MEMBANK TID’, or MEMBANK USER’.
5. Specify the address (at least 2 digits) at which the data write or read is to begin in the memory bank that was previously selected by entering ‘ADDR [ADDRESS]’, where [ADDRESS] is the desired address in hexadecimal format. (Example: ADDR 00).
6. If data is to be read, specify the number of words (16 bits) by entering ‘READWORDCOUNT [NUMBER OF WORDS]’ (Example: READWORDCOUNT 2).
7. In order to display the desired data with an inventory round, enter ‘SET TAGMETADATA2 DATA’.
8. Now that all the parameters have been set, the reading process can begin. Enter ‘RFID READ’.

RFID (UHF)

1. SET ANTENNA [A/B/AB, etc]
2. SET POWERBASE 22
3. SET READTIMEOUT 250 – This specifies the period of time the RFID Reader spends radiating before it collects the tag information (ms)
4. Place a tag in front of the antenna specified earlier
5. RFID AUTO – To start continuous radiating OR RFID READ – to radiate for 1 inventory round
6. RFID STOP – To stop radiating, only needed after an RFID AUTO

RFID TAG TABLE

1. RFID TAGTABLE ENABLED
2. RFID TAGTABLE CLEAR – Initialize the tag table
3. RFID AUTO (Optional) – To start radiating
4. RFID TAGTABLE – Will return the count of total RFID Tag Id’s in the tag table and the RFID Tag Id’s in the tag table with their first and last read timestamps.
5. RFID TAGTABLE CLEAR – Will clear the tag table (use this command when needed)

TRIGGERMODES

1. SET TRIGGERMODE [CONVEYOR,FORKLIFT, etc…]
2. SET TRIGGERINPUT [1‐4] – The number represents the photoeye(s) or other inputs that will act as trigger(s).
3. SET TRIGGERLEVEL 1 0 0 0 – The trigger level represented for all the possible input ports.
4. SET FILTERTYPE [None, Onetag, or Table]
5. SET READMODE TRIG
