Savi ST-673 Sensor Tag
Description
The Savi ST-673 tag is an active RFID tag that enables real-time tracking
and environmental monitoring of sensitive, perishable items such as
medical supplies, food stuff, and ammunition. The ST-673 features
sensors that monitor and log the temperature and humidity of assets and
their contents during transportation and while in storage. The external
mounting bracket allows an externally-mounted ST-673 to monitor the
contents of a sealed container.

Features
• ISO 18000-7 compliant active RFID tag with environmental sensor
capability
• Ideal for tracking sensitive items such as medical supplies, food, and
ammunition
• Mounting bracket for attaching tag to metallic assets
• 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. You must remove and re-insert the
battery to wake up the tag. After you re-insert the battery, you can
initialize the tag.
1. Remove the battery cap.
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.
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. Continue tightening the cap until
it is secure.

If the O-ring is not properly compressed by the cap, water leakage and
damage may occur.
Note: When the tag is not in use, disable the tag by removing, reversing,
and re-inserting the battery. Store the battery at room temperature
(50-80 °F or 10-27 °C ).
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.

3. Refer to the Savi SmartChain Mobile User Guide or the Savi Smart-
Chain WorkStation User Guide for instructions on the initialization
process.
Placing Tags on Jet Engine Shipping Containers
11
Placing Tags on Jet Engine
Shipping Containers
The Savi ST-673 Sensor Tag in the supplied metal mounting sleeve
attaches through the ports on the jet engine container to monitor humidity
inside the shipping container.
There are a variety of jet engine shipping container configurations. Some
have the mounting hole for the tag on the bottom of the container; others
have a hole for the tag higher up on a side.
In many cases the top of the container may end up on a different bottom
platform, in which case the tag should be on the bottom section.
The tag will have a 100-foot (30m) read/write range to Savi SR-650 Fixed
Readers when mounted a foot or less above the ground, up to a range of
300-feet (100m) when mounted 3 or more feet (1m or more) above
ground level. 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.
Mounting the Tag
Mounting the tag requires screws and a metal mounting sleeve. The tag,
in the supplied metal mounting sleeve, attaches through the ports on the
jet engine container to monitor humidity inside the shipping container.
The ST-673 includes these required mounting fasteners:
• Stainless steel screws and washers
• Metal mounting sleeve

Mounting the Tag on a Jet Engine Container
You receive the tag and metal mounting bracket fully assembled. Follow
the instructions to mount the unit onto a jet engine container.
1. Carefully remove the red protective film covering from the pressure
sensitive tape (PST) on the bottom of the bracket. Avoid touching the
PST adhesive.
Remove strips of
protective film
2. Open the jet engine container and locate the container port. This is the
opening for the tag mounting bracket.
3. Unscrew the nut on the mounting bracket.

4. Remove the small rubber gasket washer from the mounting bracket.
5. To mount the tag, insert the mounting bracket and tag into the port
opening.
6. Apply pressure to the tape strips by pushing firmly against the tag.
Press as hard as possible on the top of the bracket and tag.
7. On the inside of the container, replace the small rubber gasket washer
and screw the nut onto the hollow screw stem to secure the tag. Close
the jet engine container.
8. If the port opening on the container is too large for the tag to be
mounted securely, insert a metal shoulder washer before replacing the
rubber washer and nut. Ensure that the lip on the metal shoulder
washer is inserted through the orifice and is facing the outside of the
container. The metal shoulder washer must be ordered separately.

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 7.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. Install a 3.6V lithium "A" battery, matching the negative (–) and posi-
tive (+) terminals to the symbols shown on the tag housing. The tag
will not work if you install the battery in the wrong direction
(reversed).
4. Replace the battery cap on the tag.
Whenever a battery is inserted into a tag, the tag will emit 5 short
beeps, one second apart.
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. Inserting a used battery into a tag may result in what
appears to be a premature battery failure.
After the beep, continue tightening the cap until it is secure.
