OMP40-2 basics
Introduction
The OMP40-2 is an optical machine tool probe suitable for use on small to medium machining and
small multi-tasking centres. It is designed to resist optical interference, false triggering and shock.
The OMP40-2 can be operated in either ‘Modulated’ or ‘Legacy’ optical transmission modes (see page
4.1, “Reviewing the probe settings”, for further information).
When operating in ‘Modulated’ mode, the OMP40-2 becomes compatible for use with an OMM-2 or
OMM-2C receiver with an OSI or OSI-D interface, or with an OMI-2 / OMI-2T / OMI-2H / OMI-2C
receiver / interface, to provide substantially increased resistance to light interference.
In ‘Modulated’ mode, it is possible to define the probe ID. This is factory set to PROBE 1, but can be
changed to PROBE 2 for use with twin probes or PROBE 3 for use with multiple probe systems.
In ‘Legacy’ mode, the OMP40-2 is compatible with an OMM receiver and an MI 12 interface, or with an
OMI receiver / interface.
All OMP40-2 settings are configured using Trigger Logic™. This technique enables the user to review
and subsequently change probe settings by deflecting the stylus whilst observing the LED display.
Configurable settings are:
• Switch-on / switch-off method
• Enhanced trigger filter setting
• Optical transmission method
• Optical power
Getting started
Three multicolour probe LEDs provide visual indication of selected probe settings.
For example:
• Switch-on and switch-off methods
• Probe status – triggered or seated
• Battery condition
