FH-2CV expander. Add 8 CV outputs to the FH-2 per FHX-8CV. Up to seven FHX-8CVs can be connected.
Connect the FHX-8CV expansion IN with a 10-pin cable from the "Expansion OUT" at the back of the FH-2 base. If you are connecting multiple FH-2s, daisy chain them to the serial with the FHX-8CV connected to the FH-2, connecting to another FHX-8CV expansion IN. All connection cables are connected in the direction where the red stripe is located on the lower side.
The channels that are assigned to individual FHX-8Cv s are set in the jumper on the back of the module. The table below corresponds to the jumper placement and extended number. By default, jumper 3 is only ON and is assigned to extended number 1.
