The AT5118 tag can be factory-programmed, as specified by the customer, or user-programmed in the field using the AP4118 Rail Tag Programmer. The tag has extended data capacity of 1088 bits, including the 20 six-bit alphanumeric characters of data (120 bits) compatible with previous ATA/AAR read-only readers.
The AT5118 Harsh Environment Transportation Tag is beam-powered (a small portion of the RF signal continually energizes the tag’s circuitry), so no internal battery is required. In addition to giving the tag an unlimited service life, this feature limits the tag’s range and reduces the possibility of cross-reads from nearby tags. System discretion is enhanced to within a 5- to 10-foot (1.5- to 3-meter) diameter reading area.
The tag contains electronically programmable circuitry activated by the RF beam, which is broadcast by a system antenna. The tag encodes the signal received from an TransCore - brand reader system with an identification number or a data message. The encoded signal reflects back (backscatters) to the TransCore reader system. TransCore’s Amtech-brand readers — series AI1200, AI1300, AI1400, AI1600, and the Encompass® series of multiprotocol readers — can read the AT5118 Harsh Environment Transportation Tag.
