Savi ST-621 License Plate Tag Description The Savi ST-621 license plate tag is a cost-effective, active RFID tag designed for various applications, including the tracking shipping containers and other conveyances. The ST-621 features a rugged form factor design, and has a replaceable battery with a typical life of five years.
Savi ST-621 License Plate Tag Installation Guide Features • ISO 18000-7 compliant active RFID data-rich tag • 400-foot (122 meters) omnidirectional line-of-sight range for monitoring, waking-up, and RF write/read operations • Replaceable battery with a typical life of five years • FCC, HERO, ETSI, RoHS (Directive 2002/95/EC) certified Activating the Tag The tag is shipped in sleep mode.

Activating the Tag Turn cap to close Correct battery orientation Whenever a battery is inserted into a tag, the tag will emit 5 beeps. Then, the tag will emit 2 short beeps to indicate adequate battery voltage or 3 short beeps if a fresh battery is required. Whenever a battery is inserted into a tag, the tag assumes that it is a fresh battery. Inserting a used battery into a tag may result in what appears to be a premature battery failure. 3. Replace the battery cap on the tag.

Placing the Tag for Best Performance Typical locations include mounting the tag inside the middle of the container or on the outside of the container on a flat surface. For best performance, make sure the tag is: • Mounted on a metal surface. • Mounted at no less than a 6 foot (1.8m) elevation. • Mounted vertically. • Not mounted behind or between metal objects The next figure shows an example of a tag mounted on an ISO container according to the performance guidelines.

Follow the instructions in the Savi Fixed Reader documentation to locate and position the Savi Fixed Reader for best performance. Mounting the Tag You can choose among several mounting methods for the tag, including using pressure sensitive tape (PST) or a plastic mounting sleeve.
Mounting the Tag Pressure sensitive tape The magnetic mount clamps directly onto the metal surface. The magnets hold the tag securely, but allow the tag and the magnetic bracket to be removed quickly. Once a mounting sleeve is fastened to an asset, you can leave it on the asset even after the tag is removed so it is available for future use with other compatible tags. Prior to re-use, visually inspect the PST-mounted sleeve to make sure it is attached securely.

Then, the tag will emit 2 short beeps to indicate adequate battery voltage or 3 beeps to indicate inadequate battery voltage. 3 short beeps means the tag needs a fresh battery. Whenever a battery is inserted into a tag, the tag assumes that it is a fresh battery. Inserting a used battery into a tag may result in what appears to be a premature battery failure.
