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.

The SMR-650-218 Reader has a 9-foot (2.74 m) cable and is designed to operate in the Savi Total Asset Visibility Portable

Deployment Kit (TAV-PDK). See the Savi Total Asset Visibility Portable Deployment Kit User Guide for instructions on

where to plug in the Savi Mobile Reader SMR-650-218.

: In this guide, when the model of the mobile reader is not specifically mentioned, the information applies to both Savi

OTE

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.
