If you are concerned about weak or corrupted SMPTE time code, we suggest that you use timecode1 in column J of the cobra.csv script header. Doing this will allow the script to continue firing if the time code is no longer able to be interpreted by the 18R2. You can also test the timecode quality from the 18R2 in TEST mode as tc0 to tc9 will display when receiving a SMPTE time code feed. We recommend at least a tc7 value. You can also view this from the COBRA Control Panel Show Controls user interface.
For more information on timecode1 and timecode2 SMPTE sensitivity options, please see What is the difference between the timecode1 and timecode2 script argument value?.
