15.0 Setting Stationary Scan Time
The minimum stationary Scan Time needs to be set for a valid tag ID to be detected, and to take into consideration
how many tags are expected to be co located. The more tags located in the same area, the longer the scan time is
needed to identify all of the tags.
For a single tag to be identified, three pulse bursts are required. For an ID code 24 transmitter, the period length is
1310 (ms) / 1000 = 1.310 seconds. For three pulse bursts, the time would be 3*1.310 = 3.93 seconds. The
minimum scan rate should be set for 4 seconds to allow decoding of the ID for a single transmitter. If more tags are
located in the same area on the same frequency, the scan time would need to be set longer than 4 seconds. To
identify 6 tags, 12 seconds should be used. To identify more than 6 tags, a longer scan time will be needed. The
more tags located at the same time, the more time is needed to process all of the incoming pulses to identify
transmitter ID’s.
