Odd number of jumpers required
For either address selection method, the hardware is designed so that an odd number of jumpers must be
used. That is, regardless of the numerical value of the node address, the parity (P) plug/resistor jumper
must be added or removed to provide an odd number of jumpers.
Plug jumper method
To use the plug jumpers to configure the UCN node address, take diagonal cutters and remove all the
zero-ohm resistor jumpers as illustrated in the following figure (if they exist). As an example, to
configure a HPM for a UCN node address of 11, install jumpers at positions 1, 2, and 8 (1 + 2 + 8 = 11)
by bridging the two circuit pins at each position. Because an odd number of jumpers are used, the P
(parity) jumper must be removed along with those at positions 4, 16, and 32. The unused plug jumpers
can be stored at their positions by hanging them on one pin.
