companies or depart ment s.
6.5.1 Com panies Segregation by OrgID
OrgID is a unique value assigned to each company by Hi-G-Tek or by one
of its authorized dealers. Every device supplied to that company is pre-
programmed with the same OrgID at product ion, and t he cust omer can't
change it ever again. In every communication between two devices, the
caller (e.g. DataReader) sends its own OrgID value. When the consignee
(e.g. DataSeal) receives the message, it first compares the OrgID it received
with its own OrgID, and only if they match the consignee performs the
command and sends its response. If a DataSeal receives a message a
different OrgID than its own, it turns on the Ille gal O rgID flag in the Long
Status, and ignores the message.
There's one exception in which a DataSeal can respond to a message with a
different OrgID in order to allow collaborat ion with service providers. This
is described in more det ails in sect ion 6.5.3.
6.5.2 Department Isolation
Department is a unique value assigned by a company to a group of devices
belonging t o the same depart ment . It is possible to isolat e equipment
bet ween depart ment s by using t he Department paramet er in the various
devices.
The default value of Department is zero in all devices. When set to that
default sett ing, all t he devices can communicat e wit h one anot her without
any limitations.
If a DataReader's Department value is not zero, it can communicate only
with DataSeals that has the same Department value.
