Chapter 1: Introduction
General Information
The Edge is a 7-axis, articulated arm with a spherical working volume. Each joint
has a rotary optical encoder. The signals from these encoders are processed, using
advanced error coding and temperature compensation technology, and positional
data is sent to the touch screen controller, or the host computer using various
wired and wireless communication protocols.
The Base Assembly contains the majority of the electronics, including a power
switch, status indicators, fold-down touch screen controller, battery pack bay, and
communication ports. There are five major communications ports on the Edge
located on the Base Assembly:
• USB 2.0 Host Port (located on the fold-down controller)
• USB 2.0 Device
• Ethernet (802.3)
• Bluetooth (Internal Base Module)
• Wireless Local Area Network (WLAN 802.11 - Internal Base Module)
The Edge uses a non-volatile read/write FLASH memory. This memory stores
programming and some compensation data for the Edge. There are proprietary
methods that are capable of erasing, reading, and writing the FLASH memory.
These methods are used during manufacturing and field updating. Security for
the FLASH is limited to the anonymity of the access methods and the
unavailability of documentation for the address structure of the FLASH memory.
The only dynamic data stored in the Edge are settings which relate directly to the
operation of the Edge. Examples include the probe XYZ position, connection
settings, etc. The Edge does not maintain in memory, or cache, measurement data
of any type. Measurements recorded with the Edge are sent directly to the
properly connected computer.
The Probe End Assembly is found at the farthest point from the base. It is free to
rotate, has two control (Red and Green) buttons and two circular LED indicators
that provide visual feedback to the user. This assembly provides for the
attachment of probes and handle accessories.
