Create and Load Scripts to the 18R2 Controller

Scripts are created using a computer software program that generates a COBRA compatible script file. You will save the script file to a USB drive, and then insert the USB drive into the 18R2 Controller.

Steps to Load a Script into the 18R2

  1. Save cobra.csv file onto a USB drive.
  2. Turn off 18R2 and place USB into the 18R2.
  3. Power on the 18R2 and allow it to boot up normally.
  4. Once finished booting up, LEDs will circle on the main display. This may take seconds or minutes depending on the size of the script.
  5. Once complete, the 18R2 LEDs (1-18) will display all green (successful) or all red (unsuccessful). If unsuccessful, the 18R2 will rotate through the error codes and line numbers on the 7-segment displays. Script errors are displayed with an ER on the upper display and the code number on the lower display. For more information, see the 18R2 error section of the Error Code Reference Guide.

The 18R2 loads the scripts from the USB drive and saves them to the 18R2. The 18R2 will retain these scripts even if powered off or if you remove the batteries. When loading new scripts into the 18R2, the old scripts are erased and replaced with the new scripts. For more information on using scripts with the 18R2, please see the 18R2 Controller User Guide; Scripting.
