Figure 3.6 –VPT10-H connection in multidrop mode.
Note that up to 63 devices can be paralleled connected on the same line. Caution must be taken when many
transmitters are connected on the same power line due to voltage drop on 250 ohm resistor and guarantee power
supply voltage is enough (Figure 3.7).
