This coupler is needed to enable communication between a USB or RS232 main station and a control. Insert the coupler into the hole of the main station and lay the control on top of the main station. The control will send the RF signal from the one control to the other.
The older, larger BS7s and the smaller, newer BS8s each have two options for mounting holders. One is the bracket - a piece that runs lengthwise, with the control snapping into place. The other is the plate - a piece the size of the base of the control, into which the control snaps.
