SMR-650 Reader Communication
The SMR-650 Reader has an ultra high frequency (UHF) transceiver and
low frequency (LF) transmitter that communicate with all Savi RFID tags
via the UHF and LF antennas. Your software determines if you are using
UHF or LF commands.
The SMR-650-212 Reader works on a wireless or wired LAN so you can
download and upload information to and from your database.
UHF Mode
The UHF transmitter sends commands and write information to Savi
RFID tags. In UHF mode, the mobile reader supports single and continuous
collection modes.
When the mobile reader is in single UHF mode, you can only perform
one tag collection within a fixed radius. When the mobile reader is in
continuous UHF mode, you can perform multiple tag collections while
moving through a facility.
The yellow status LED shows when the SMR-650 Reader is receiving
a UHF signal. When the yellow LED flashes, it indicates that the mobile
reader received a valid data packet. The yellow LED continues to flash until
all data is received. The yellow LED is not functional during UHF transmit
or LF transmit.
