4-36 Setting Up and Using Laser Alignment Fixtures
There may be times when an RF communication between each sensor
head and the UltraSpec analyzer is not convenient. Moving or keeping the
analyzer closer to the laser heads can minimize this inconvenience.
The sensor heads have memory for saving alignment readings. If commu-
nication with the UltraSpec analyzer is broken during rotation (while using
the Auto Sweep mode), these readings are stored in memory until they can
be transmitted. When the sensor head is turned off, the memory data is
erased.
If the UltraSpec analyzer is out of range of one or both sensor heads or if
some sort of RF interference is occurring, it will repeatedly attempt to com-
municate with the sensor heads. A message will be displayed on the ana-
lyzer until the communication link is established.
When communication using RF becomes difficult, CSI recommends that
you use the Direct Connect link as described in the following section.
