Multiple prox.pad
plus Units Together
For multiple door applications, the prox.pad plus can
be networked together. When networking prox.pad
plus devices together on an RS-485 system, the
prox.pad plus units are all wired in parallel. This net-
working capability is available when connecting di-
rectly to your personal computer’s COM port or when
communicating over a computer network with the IEI
Gateway. Figure 3-10 shows an example of networking
multiple units together. The maximum number of de-
