4.11 Remote Access (Tunneling)
To "tunnel", in this context, is to transmit data between two points through a private conduit
on a shared or public network. The network could be an Ethernet LAN, a WAN, or the
Internet. The iServer allows for a connection between a serial device and a PC, or between
two serial devices, using an existing network rather than dedicated wiring.
The connected serial devices to iServer’s can communicate with each other back and forth
over the networks. This characteristic is called Tunneling and is illustrated in
Figure 4.25
.
Figure 4.25 Device-to-Device Communication
In order to use this Tunneling feature, some settings are required within the local and
remote iServer’s.
