Version 1.0
Setup
Before continuing with setup please be sure to read the Safety section of this document.
Below is the connection diagram for the AC/DC adapter.
The FRS Switches shall be used with a customized AC/DC adapter. Users of the FRS Switch must provide
their own AC/DC adapter in which the DC side power line is spliced and terminated in a banana plug
connector on each side of the splice as depicted above. The ground line should not be spliced.
The FRS Switches have 3 exposed receptacles.
Two banana receptacle connectors to interface with the DC output of an AC/DC power adapter.
One 2.1mm barrel jack receptacle connector used for the control signal.
The two banana receptacle connectors have corresponding labels above them to indicate which side of
the splice to connect. Labels will read “AC Adapter” to indicate that the banana plug connector on the
AC/DC adapter side of the spliced power line be connected here. While the other label will read “to
UUT” to indicate that the banana plug connector on the DC barrel jack side of the spliced power line be
connected here. Reversing the orientation can damage the FRS Switch. See example pictures of an FRS
Switch below with labels above the banana receptacle connectors.
The 2.1mm Barrel Jack Receptacle is labeled “Control” and is used with a DC signal to enable and disable
the switch. A corresponding barrel jack plug will be shipped with each FRS Switch. The FRS Switch does
not come with a control cable. The user must create their own control cable using the barrel jack plug
included in the shipment. See example picture of an FRS Switch below with a Control label above the
2.1mm barrel jack receptacle.
