We had some A-188-1 for repair with a similar fault (not working sockets of
the small board). In all cases the reason were broken tracks near the jack
sockets of the smaller pc board (i.e. the board with the 4 switches). We
assume that the faults happened during transportation or module installation
if the pc board is bended too much (e.g. because of too strong
wrapping/pressure during the transportation or if the module is held with
the two pc boards only during installation into the frame). If you are
experienced with soldering I'd recommend to bride over the pcb tracks that
lead away from the jack sockets (e.g. by connecting a wire between the jack
socket pin and the pin of the next electronic part of the pcb track, usually
a resistor).

If you are not able to to this repair yourself please send the module to the
dealer/representative where you purchase the device.

For the new pc A-188-1 boards (from third series) we asked our manufacturer
to use a thicker cooper for the pc boards to avoid such problems.

Sorry for any troubles. Of course we try to avoid such problems but for new
modules they may appear only after some weeks or months.
