DF8000 unit address settings
Note that the DF8003 units that include 4 to 6 I/O modules, i.e. the double units,
always allocate two consecutive addresses on the RS485 line: the address se-
lected on S1-5 to S1-8 and the subsequent one. This applies both to even and odd
addresses.
On the front panel, the CPU module has also a reset button that can generate
hardware reset on the CPU microprocessor.
Internally, 6 jumpers (J1...J6) are available to reverse the 0/1 logic on each of the
six I/O modules (positive or negative logic). If the jumper is installed, then the cor-
responding I/O modules functions with positive logic (see Fig. 8).
