1.3.4 Multiple Protocols and/or Services

Prior to the iNET Series, two radios were often used to service two dif-
ferent types of devices (typically connected to different SCADA hosts).
An iNET or iNET-II radio provides this functionality with a single
remote radio. Each of the two serial ports can be connected via IP to dif-
ferent SCADA hosts, transporting different (or the same) protocols.
Both data streams are completely independent and the transceiver pro-
vides seamless simultaneous operation as shown in.

By using a single radio, the cost of deployment is cut in half. Beyond
requiring only one radio instead of two, the biggest cost reduction comes
from using half of the required infrastructure at the remote site: one
