Tag Communication
The Savi Fixed Reader SR-650-101 can transmit control commands and
data over a UHF link to SaviTags. In return, the SaviTags transmit status
information, recognition codes, and data over the UHF link to the reader,
depending on the commands the tag received.
The Savi Fixed Reader SR-650-101 supports three UHF air interface
protocols for SaviTags, which are formats through which Savi products
transmit data:
◆ Batch Collection System® (BCS)
◆ Extended BCS (EBCS)
◆ EchoPoint
BCS and EBCS air protocols support 20-bit tag identification; EchoPoint
air protocol supports 32-bit tag identification.
The following table lists the SaviTag models that are compatible with the
