3.3 Networking

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-
