The Master Control Units (MCU) for the ION Laser Tracker and the V1 / V2 Laser Trackers are electronically equivalent and can be interchanged provided that the V1 / V2 MCU has had its firmware updated to a revision compatible with the ION Tracker. If the MCU was serviced recently, then the firmware would've been updated during that service. The current version of MCU Firmware can be downloaded from the Customer Support section of our web site.
The MCU's for the Vantage FARO Tracker are not compatible with the ION / V1 / V2 laser trackers. They have different cable connections and therefore can not be interchanged.
