Works fine with dynalite. self powered by 232 or 485 port. Comes in really good packaging - well protected from shipping damage.
Adaptor PCB is not the same as one shown in pic, but still woks fine. Have only used for a couple of days, but seems quite stable. Dynalite requires bi directional coms and this unit works fine for it. I couldnt buy the components for that price.
