They'll work just fine without a sitemonitor. Early syncinjectors ran standalone. They each had non-microcontroller based timing hardware in them, and adding sitemonitor control added a fair bit of cost. For a brief period, we actually had a version with this added on functionality, which we sold as a 'sitemonitor controlled syncinjector'.
When we switched the design to the latest iteration (RevH), it was actually cheaper to use a microcontroller to control all of the timing. At which point, having them be able to be controlled and monitored by a sitemonitor was effectively free, so they got that capability by default, and the separate sitemonitor controlled syncinjectors ceased to exist. And as an aside, this 'work in standalone mode' is not confined to the syncinjectors. The vast majority of the sitemonitor products will actually work without a base unit attached. There's a couple which need a separate power supply, and a couple that don't make sense to use in standalone, but the rest are perfectly happy to do what they're supposed to without the base unit. -forrest On Fri, Nov 21, 2014 at 2:00 PM, Josh Luthman via Af <af@afmug.com> wrote: > I have a site where I'm providing DC up the tower and want to minimize > products up there.
