One should check the message before hitting the send button.
Of course, the box is controlled via DC, the message should have read:
a *DC* Power-supply plus some diodes etc.
The *DC* is fed into the coax and switches the relais in the control-box
under the loop. 4 positions are possible using *DC* and diodes.
Sorry for the senior moment.
