It is a Mode S transponder. It is compatible with Mode A/C SSR. Think
of Mode S as an enhancement to Mode A/C. It's not an alternate choice.
It really makes no sense to ask if these Mode S transponders support
mode A/C.
Paul's comparision table says it's just "Mode S", while Becker 6401 is
"Mode A, A+C, S". Technically it is possible to create a mode-S only
transponder. But I'm not sure if it's legal (certifiable).
If Trig supports A/C, that's good to know!
