Similar to the Set co mm an d, Suspende d Se t is used to set a DataSeal for
new use. Unlike the Set command, when performing a Suspende d Se t
command, the Sealing Wire Must be opened (or completely disconnected
from the DataSeal). T he DataSeal will become armed (Set) once the
Sealing Wire has been connected to the DataSeal and closed.
11. Approve Open
The Approve Open command allows a Sealing Wire to be opened after the
DataSeal has been set in a way that the application can determine that the
DataSeal was opened with an approval. When the Sealing Wire will be
opened after receiving this command, the application will be a ble to
det ermine that t he opening is approved by examining the Approved Open
flag in the DataSeal's Status.
6.3.2 DataSeal's Status
The DataSeal's Status consists of 4 bytes. A DataReader may be used to
request the DataSeal's Status. The DataSeal's Status is used to indicate the
DataSeal's current state and is a bitwise value. Each bit in the Status
represents a specific status flag. The DataSeal's Status is divided into the
Short Status and Long Status paramet ers as explained below:
The DataSeal's Short Status parameter consists of 1 byte (8 bits) which is
a subset of the Long Status parameter. The Short Status contains the most
important flags. T hese flags are:
1. Tampered – The Tampered flag gets set if the Sealing Wire was
opened or tampered with. It remains set even if the Sealing Wire is
closed again. It can only be unset by performing on of the Se t
commands.
2. Low Battery Warning – Battery is low, replace the DataSeal.
3. Opened – Indicates that the Sealing Wire is open.
