About the Mobile Readers
The Savi® Mobile Reader SMR-650-217 and SMR-650-218 are portable radio frequency identification (RFID) readers that
communicate with active Savi RFID tags. The SMR-650-217 Reader and SMR-650-218 Reader include a USB interface
connector and work with a notebook or desktop computer or other devices with standard USB serial connectors. The only
difference between the SMR-650-217 Reader and the SMR-650-218 Reader is the length of the cable for the USB connector.
The SMR-650-217 Reader has a 20 inch (50.8 cm) cable and is designed to plug into a computer USB port or a USB hub.

In this guide, when the model of the mobile reader is not specifically mentioned, the information applies to both Savi
Mobile Reader models and kits.
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 UHF and LF antennas. The software on the computer or device determines if you use UHF or
LF commands.
UHF Mode
The UHF transmitter sends commands and write information to Savi RFID tags. In UHF mode, the mobile reader supports
single and continuous collections.
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 amber status LED is visible when the SMR-650 reader is receiving a UHF signal and is an indication that the tag ID
and the information in the data packets is being validated. When the amber LED flashes, it indicates that the mobile reader
received a valid data packet. The amber LED is only functional when receiving UHF data and is not functional during UHF
or LF transmission.
