In AUTO mode, the Data Carrier (DC) can always be accessed when the
INHIBIT input is ON while the V600-HAM42-DRT power is ON. Therefore the
Data Carrier is automatically accessed when the Data Carrier enters the trans-
mission area, with no need for a simultaneous trigger (TRG) input.
Read data will be output with the data output signal while the Data Carrier is with-
in range.
If the Data Carrier is stopped within the transmission area after reading is ac-
cessed, it will not be accessed again. After the Data Carrier goes out of the trans-
mission area, or after operation is stopped by the INHIBIT input turning OFF, the
Data Carrier will revert to wait status.

If this time (t ) is shorter than the output time set by pin 1 of DIP switch 2 (out-

put mode), the output will continue during the output time. (When the DIP switch
pin is OFF, the output time is 100 ms; when ON, the output time is 500 ms.)
