Initialization issues

Problem

One or both of these issues occur:

  • The MX9 either hangs when the sensors are initialized or simply shuts off after a short time.
  • The three LEDs on the Control Unit (CU) continuously flash green for about 10 minutes, and then the Control Unit and Sensor Unit LEDs fail and eventually start flashing red.

Solution

  1. Try to reconnect the ODU cable.
  2. Check all the elements of the ODU cable connectors and sockets. If there is no visible damage.
  3. Try a different ODU cable. Please contact Trimble dealer in order to get another ODU cable.

Problem Details

Most likely the CU lost the connection to Laser1 and Laser2. In this case TMI log files will have many errors and most of them will be referring to the Laser 1 / Laser 2 connection failures like:

MSG 620 from Laser_1: "MSG_LAS_LASER_STATUS_ERROR"
