DCM1 & DCM1e Installation and User Guide V1.0 65
PCB jumper locations and settings.
The DCM1 has various internal jumpers, the setting of which
may require alteration during installation. The table below
lists each jumper and its purpose, together with the factory
default setting.
The diagram below the table shows the locations of the internal
jumpers (not to scale). In the case of the jumpers having two
possible positions, the black square in the symbol indicates
the default setting. If any jumpers need to be changed, undo
the eight screws securing the top cover of the DCM1, and
remove it. Use a pair of snipe-nosed pliers to gently remove
the jumpers, and to reposition them if necessary. Rex the
top cover using the original screws.
