Communicating With Your Wireless Tool; Establishing First Communication; Moving Tools Between Gateways - Starrett W798 Handbuch

WIRELESS OVERVIEW

Communicating with your Wireless Tool

Starrett Wireless Tools communicate with a DSA 4.0 Gateway using
encryption. This prevents outsiders from 'listening in' to the data
being sent. The first time a wireless tool talks to a Gateway they
establish a set of security keys. Both sides remember the key and
use it to reestablish communications. This can occur when the tool
is turned off or is moved out of radio range. Once the tool is within
range and turned on, the Wireless Tool and the Gateway will use the
security keys to automatically resume communicating.

Establishing First Communication

Make sure your DSA 4.0 system is on and communicating with the
Gateway (1). Turn on the tool, and after a little while the tool will
appear in the DSA 4.0 application on the Gateway Tab, match the UID
number on the tool with the one in DSA 4.0. The Permissions column
will be Red and labeled "Blocked". Click on the Blocked Button. The
Button will immediately turn Gray and display "Updating". After a
slight delay the button will turn green and display Allowed. At this
time the wireless tool has a blank security key, and after a slight
delay the Connection Status column will change to Online and show
Green. This means that they have exchanged keys and successfully
established a secure link.

Moving Tools Between Gateways

If a Wireless Tool has established a secure link with a Gateway (1) and
you want to move the tool to a new Gateway(2), the tool's security
key needs to be reset.
