I bought this set with the expectation, that it would be a “normal” set with 5 dip-switches. The bad news was: you can only use 16 devices of these set (without modifying the hardware), because you can only set 4 house codes …
The good news is: the chipset is the well known 2262/2272 chipset. The layout on the mainboards are different to those with dip switches: only D0-D3 (4 bits) are used to set the house code, the “normal” sets are using D0-D4 for the house code…
But you can use it with de usual setting “switch 2” if you look at the table, where I calculated from the Renkforce devices to the setting for switch2
