Point-to-Point System

Where permitted, the transceiver may also be used in a point-to-point
arrangement. A point-to-point system consists of just two radios—one
serving as a master and the other as a remote (see Figure 5). It provides
a simplex (or half-duplex) communications link for the transfer of data
between two locations.

IP/Ethernet Polling

Many newer data/control networks employ IP/Ethernet connectivity
throughout the system. The SD transceiver is well suited to provide con-
nectivity between such sites using its RJ-45 modular connector on the
front panel. Figure 6 shows an overview of such a system.
