It's great that DCS veterans are sharing their wisdom with novices here.
Somewhere I read, maybe in Barry's book, that one can keep the auxiliary power source (for me it's a Z500 brick) plugged in all the time to power the TIU, and doing so avoids the need to reboot the TIU. Also, doing so is comparable to keeping one's computer on all the time.
Do you think that keeping the TIU powered up all the time (with the little red light on) is a good idea? Could doing so be a safety hazard?
