Setting the Loop Address
 The analogue address of the Module is set using the first 7
switches of the 8-bit DIL switch, which in the case of the
Standard CHQ is located through the cut-out section on the top
of the PCB cover. On the DIN version, this switch is located on
the edge of the PCB behind the clear door (see Fig 4).
 The switches are numbered 1 to 8 (left to right):
