Savi ST-674 Sensor Tag Description The Savi ST-674 tag is an active RFID tag for real-time tracking and environmental monitoring of sensitive, perishable items such as medical supplies, food stuff, and ammunition. The ST-674’s sensors monitor and log environmental conditions, both temperature and humidity, of assets and their contents during transport and while in storage.
Savi ST-674 Sensor Tag Installation Guide Figure 3: Bottom view Sensor port Features • ISO 18000-7 compliant active RFID tag with environmental sensor capability • Ideal for tracking sensitive items such as medical supplies, food, and ammunition • Supports low-frequency technology for more precise locating capabilities • Supports USB for reading and writing • 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 open Remove battery as shipped 2. Remove the battery. Wait a few seconds and then reinsert the battery, matching the negative (–) and positive (+) terminals to the symbols shown on the tag housing. The tag will not work if you install the battery in the wrong direction (reversed). Turn cap to close Correct battery orientation Whenever a battery is inserted into a tag, the tag will emit 5 beeps.
Savi ST-674 Sensor Tag Installation Guide Then, if the tag emits a long (1/2 second beep), that means it has an internal sensor failure. 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.
Initializing the Tag Initializing the Tag Once you activate the tag, you can initialize it for immediate use. 1. Unplug the USB port cover. 2. Insert the USB cable into the USB port on the tag and connect the other end to the USB port on the computer.
Savi ST-674 Sensor Tag Installation Guide 3. Refer to the Savi SmartChain Mobile User Guide or the Savi Smart- Chain WorkStation User Guide for instructions on the initialization process. Placing the Tag for Best Performance Savi Technology recommends that you mount the tag on a flat surface, with the tag aligned vertically. For best performance, place the tag as high as possible, safe from impact (for example, between the ribs of an ISO-type shipping container), and away from obstructions on the asset.
Placing the Tag for Best Performance Figure 4: Asset tag mounted on an ISO container door Note: Make sure you clean the surface of the container or other asset before attaching the tag. The tag will have 400-foot (122m) read/write range to Savi SR-650 Fixed Readers. For the most consistent communications with the tag, the Fixed Readers must be mounted: • to have an unobstructed line-of-sight to the tag • at 20 feet (6m) or higher caution: Tags mounted close to the ground may have less range.
Savi ST-674 Sensor Tag Installation Guide Mounting the Tag You can choose among several mounting methods for the tag, including using pressure sensitive tape (PST) or a plastic mounting sleeve. Whichever mounting method you select, the goal is to prevent accidental loss of the tag by sudden impact, vibration, or shock during transport. The fastener you choose often depends on the material from which the asset or container is constructed and your personal preference.
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.
Savi ST-674 Sensor Tag Installation Guide Security hole Replacing the Battery The tag is equipped with non-volatile memory, which means stored data is not lost when you replace the battery. 1. Remove the battery cap. 2. Remove the discharged battery from its compartment. For more information, see “Activating the Tag” on page 6. The lithium battery can be harmful to the environment. Follow current procedures for safely disposing of lithium batteries. The battery cannot be reused or recharged. 3.
Contacting Savi Support Then, if the tag emits a long (1/2 second beep), that means it has an internal sensor failure. Remove the battery and insert it again. If the tag emits the same long (1/2 second) beep, do not use the tag. 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.
