Connecting Instruments to LAN 5
Agilent Connectivity Guide 95
Private Instrument Subnet on Corporate Intranet
In this topology, the computer is on the same subnet (same side of the
router) as the LAN instruments. Both are “shielded” from the corporate
LAN by the router. Other PCs on the network cannot easily reach the
instruments. The router runs a DHCP server for the local devices,
including the computer. This scenario presumes that the router does
Network Address Translation (NAT) when the PC or instruments
attempt to access the corporate intranet. Note that if the router were
replaced by a hub, switch, or bridge, then this would be equivalent to an
open instrument subnet topology (see next example).
